In this entry, the central issues are these: 1. Is the concept of causation basic and unanalyzable, or, on the contrary, does it stand in need of analysis? 2. If it does need to be analyzed, how can this be done? Many different answers have been offered to these questions. But the various approaches can be divided up into four general types, which I shall refer to as direct realism, Humean reductionism, non-Humean reductionism, and indirect, or theoretical-term, realism. This (...) fourfold division, in turn, rests upon the following three distinctions: first, that between reductionism and realism; second, that between Humean and non-Humean states of affairs; and, third, that between states that are immediately observable and those that are not. Given those distinctions, I shall discuss what can be said for and against the four general approaches to causation mentioned above. (shrink)

Direct realism with respect to perceptual experiences has two facets, an epistemological one and a metaphysical one. From the epistemological point of view it involves the claim that perceptual experiences provide immediate justification. From the metaphysical point of view it involves the claim that in perceptual experience we enter into direct contact with items in the external world. In a more radical formulation, often associated with naive realism, the metaphysical conception of direct realism (...) involves the idea that perceptual experiences depend on the items in the external world they are related to. This paper describes a simple account that makes room for immediate justification provided by perceptual experience. The simple account establishes an explanatory relation between the justificatory role of a perceptual experience and the fact that such an experience provides a reason for a belief. The account is evaluated in the light of some objections. Different ways to react to those objections are discussed. It will appear that in order to preserve the explanatory relation established by the simple account, one has to accept naive realism. By breaking the connection between reason and justification, on the other side, one jeopardizes the possibility for perceptual experience to deliver immediate justification. (shrink)

Naïve realists traditionally reject the time lag argument by replying that we can be in a direct visual perceptual relation to temporally distant facts or objects. I first show that this answer entails that some visual perceptions—i.e., those that are direct relation between us and an external material object that has visually changed, or ceased to exist, during the time lag—should also count as illusions and hallucinations, respectively. I then examine the possible attempts by the naïve realist to (...) tell such perceptions apart from illusions and hallucinations, and after showing the inadequacy of the answers relying on a mere counterfactual or causal criterion, I explain why the problem is solved by introducing a view of visual perception as temporally extended into the past of objects and, in particular, as consisting in the whole causal chain of events or states of affairs going from external material objectxto subjectS. But this solution is not immune from defects for the naïve realist. I show that this view of perception raises a number of significant concerns, hence leaving the issue of the time lag problem still open for naïve realism. (shrink)

According to proponents of relational direct realism, veridical perceptual experiences are irreducibly relational mental states that include as constituents perceived physical objects or intrinsic aspects of them. One consequence of the theory is the rejection of the causal theory of perception. This paper defends the relational theory against several objections recently developed by Paul Coates. He argues that the required experiential relation is incoherent and unmotivated. The argument that it is incoherent commits a fallacy. In reply to the (...) argument that it is unmotivated, I suggest that the relational theorist's appeal to transparency provides sufficient motive and, when properly clarified, defeasibly justifies the theory as well. Coates also argues that rejection of the causal theory leaves relational theorists without any way of determining which object is perceived or of accommodating our scientific understanding of perceptual experiences as causally dependent on physical objects. I reply that relational theorists are able to provide the required explanations and discuss how the relational theory is consistent with this scientific understanding of perceptual experience.

This essay responds to Jeff Malpas's foregoing article, itself written in response to my various publications over the past two decades concerning Donald Davidson's ideas about truth, meaning, and interpretation. It has to do mainly with our disagreement as regards the substantive content of Davidson's truth-based semantic approach in relation to the problematic legacy of logical empiricism, including Quine's incisive but no less problematical critique of that legacy. I also raise questions with respect to Malpas's coupling of (...) Davidson with Heidegger, intended to provide a more adequate depth-ontological grounding for the formalized (logico-semantic) conception of truth that Davidson adopts from Tarski. My essay then argues the case for an outlook of objectivist causal realism joined with a theory of inference to the best, most rational explanation that would satisfy this need in more philosophically (as well as scientifically) accountable terms.

Minimally, causal realism (as understood here) is the view that accounts of causation in terms of mere, regular or probabilistic conjunction are unsatisfactory, and that causal phenomena are correctly associated with some form of de re necessity. Classic arguments, however, some of which date back to Sextus Empiricus and have appeared many times since, including famously in Russell, suggest that the very notion of causal realism is incoherent. In this paper I argue that if such objections (...) seem compelling, it is only because everyday expressions concerning causal phenomena are misleading with respect to certain metaphysical details. These expressions generally make reference to the relations of events or states of affairs, but ignore or obscure the role played by causal properties. I argue that on a proposed alternative, an analysis in terms of causal processes, more refined descriptions of causal phenomena escape the charge of incoherence. Causal necessity is here located in the relations of causal properties. I distinguish this view from the recent process theories of Salmon and Dowe, which are disinterested in causal realism.

Realism is vulnerable to the sceptical challenge. Metaphysical realism, in general, is the basis of different specific realist positions, such as semantic, internal, causal, intentional, explanatory, scientific, modal, etc., realisms. One aim of the paper is to show how these specific forms satisfy some of the realist criteria and also what counts as antirealism with respect to these forms. The other aim is to cope with realist antireductionism.

ABSTRACT When Hume, in the Treatise on Human Nature, began his examination of the relation of cause and effect, in particular, of the idea of necessary connection which is its essential constituent, he identified two preliminary questions that should guide his research: For what reason we pronounce it necessary that every thing whose existence has a beginning should also have a cause and Why we conclude that such particular causes must necessarily have such particular effects? Hume observes that our belief (...) in these principles can result neither from an intuitive grasp of their truth nor from a reasoning that could establish them by demonstrative means. In particular, with respect to the first, Hume examines and rejects some arguments with which Locke, Hobbes and Clarke tried to demonstrate it, and suggests, by exclusion, that the belief that we place on it can only come from experience. Somewhat surprisingly, however, Hume does not proceed to show how that derivation of experience could be made, but proposes instead to move directly to an examination of the second principle, saying that, "perhaps, be found in the end, that the same answer will serve for both questions". Hume's answer to the second question is well known, but the first question is never answered in the rest of the Treatise, and it is even doubtful that it could be, which would explain why Hume has simply chosen to remove any mention of it when he recompiled his theses on causation in the Enquiry concerning Human Understanding. Given this situation, an interesting question that naturally arises is to investigate the relations of logical or conceptual implication between these two principles. Hume seems to have thought that an answer to would also be sufficient to provide an answer to. Henry Allison, in his turn, argued that the two questions are logically independent. My proposal here is to try to show that there is indeed a logical dependency between them, but the implication is, rather, from to. If accepted, this result may be particularly interesting for an interpretation of the scope of the so-called "Kant's reply to Hume" in the Second Analogy of Experience, which is structured as a proof of the a priori character of, but whose implications for remain controversial.

In Explaining Attitudes, Baker argues that we should treat our everyday practices as relevant to metaphysical debates, resulting in a stance of realism with respect to intentional explanations. In this chapter I will argue that if one is going to be a practical realist about anything, it should be the self, or subject of attention. I will use research on attention combined with the stance of practical realism to argue in favor of a substantive self. That is, (...) I will present an account of the self that directs and controls attention, in line with our everyday view of the self. I will contrast this account with what I call the “illusion view,” which presents the self and its apparent causal power in the case of attention as an illusion. My account of the self will make use of several of Baker's ideas, including non-reductive materialism and broad supervenience. (shrink)

First published in 1925, A Theory of Direct Realism is divided in two parts: the first part is an attempt to formulate a realistic theory of Perception and of the physical world, and the second part is an exposition of Hegelian idealism and its compatibility with realism. This book on direct realism will be of interest to students of philosophy, history and literature.

Peut-on et doit-on admettre des propriétés non physiques? Une ontologie minimale accepte seulement la réalité des propriétés physiques. Elle prend appui sur un critère d’existence restreint : le critère causal. A l’inverse, une ontologie d’accueil affirme la réalité d’au moins certaines propriétés non physiques, et conteste par là la validité du critère causal. Le but de cette investigation est de défendre une version modérée du réalisme par rapport aux propriétés non physiques et de proposer un nouveau critère d’existence (...) : le critère explicatif.

Rom Harré's generative account of causality has been drawn on heavily by advocates of critical realism. Yet Harré argues that critical realists often exaggerate the extent to which powerful causal explanations of social phenomena can be developed. Certain proponents of critical realism have responded to Harré's criticisms by suggesting that it is useful to consider the relevant issues in relation to the familiar Aristotelian classification of four causes. In this paper I contribute to this debate and pursue a similar (...) strategy. The paper adds to existing contributions in two ways. Firstly, I outline how Harré sees his generative account of causality as linking up with Aristotelian themes. It emerges that Harré at times conceives of his generative theory as part of an alternative to the Aristotelian system while at other times he draws connections between it and a reformulated account of formal causality. Secondly, I argue that when we consider the positions of Harré and proponents of critical realism on the scope of causal explanation in the social realm in relation to the interpretation of final causes offered by another philosopher profoundly influenced by the Aristotelian tradition, namely Charles Peirce, we can see both as limited in certain respects.

Recent work in defence of direct realism has concentrated on the representationalist and disjunctivist responses to the arguments from illusion and hallucination, whilst relatively little attention has been given to the argument from causation which has been dismissed lightly as irrelevant or confused. However such charges arise from an ambiguity in the thesis which is being defended and the failure to distinguish between metaphysical and epistemological issues and between factual and conceptual claims. The argument from causation, as an argument (...) against the conjunction of metaphysical direct realism and an explanation of the perceptual process in terms of a naturalistically understood causal chain of events, has not been answered in the philosophical literature. Moreover when the process of perception is fleshed out in terms of contemporary cognitive science, the difficulties are compounded. Neither representation-friendly mainstream cognitive science, nor representation-averse radical embodied cognitive science, is compatible with a theory of perception which is at the same time both direct and robustly realist.

Independence of Conditionals (IC) has recently been proposed as a basic rule for causal structure learning. If a Bayesian network represents the causal structure, its Conditional Probability Distributions (CPDs) should be algorithmically independent. In this paper we compare IC with causal faithfulness (FF), stating that only those conditional independences that are implied by the causal Markov condition hold true. The latter is a basic postulate in common approaches to causal structure learning. The common spirit (...) of FF and IC is to reject causal graphs for which the joint distribution looks ‘non-generic’. The difference lies in the notion of genericity: FF sometimes rejects models just because one of the CPDs is simple, for instance if the CPD describes a deterministic relation. IC does not behave in this undesirable way. It only rejects a model when there is a non-generic relation between different CPDs although each CPD looks generic when considered separately. Moreover, it detects relations between CPDs that cannot be captured by conditional independences. IC therefore helps in distinguishing causal graphs that induce the same conditional independences (i.e., they belong to the same Markov equivalence class). The usual justification for FF implicitly assumes a prior that is a probability density on the parameter space. IC can be justified by Solomonoff’s universal prior, assigning non-zero probability to those points in parameter space that have a finite description. In this way, it favours simple CPDs, and therefore respects Occam’s razor. Since Kolmogorov complexity is uncomputable, IC is not directly applicable in practice. We argue that it is nevertheless helpful, since it has already served as inspiration and justification for novel causal inference algorithms. (shrink)

My analysis of temporal direction begins by establishing that time-reversal scenarios, scenarios in which the direction of time itself is reversed, whether locally or globally, are incoherent. Building on this conclusion, I argue that temporal directionality cannot be defined or explicated in terms of processes in time, such as the movements of celestial bodies, biological evolution or radioactive decay. In other words, while it is easy to imagine any process occurring in reverse, one cannot define the "earlier"/"later" relation by appeal (...) to the stages of a process, for example, the consecutive stages of radioactive decay. The second section of the paper turns to a study of our firsthand experiences, and qualifies this result by arguing that experiences constitute the one class of events that cannot so much as be conceived as reversed in time. In the third section I suggested that our firsthand experiences figure as a standard by means of which temporal direction is given to us. I further argue that, despite the pivotal role played by experience in this scheme, we are fully warranted in being realists with respect to temporal directionality. (shrink)

I consider the first part of Marty’s Raum und Zeit, which treats of both the nature of space and spatial perception. I begin by sketching two charges that Marty raises against Kantian and Brentanian conceptions of space (and spatial perception) respectively, before detailing what I take to be a characteristically Martyan picture of space perception, though set against the backdrop of contemporary philosophy of perception. Marty has it that spatial relations are non-real but existent, causally inert relations that (...) are grounded in space, which is itself non-real but existent. Objects do not inhere in space in the way properties inhere in substances. Rather, there is a ‘non-real’ relation of ‘fulfillment’ (Erfüllung) that holds between objects and places in space, which itself subsists. I consider whether any contemporary philosophy of perception is equipped to make sense of Martyan space perception and I suggest that the most promising conception is Naïve Realism. I then outline a difficulty for this theoretical translation. Naïve Realism is a direct theory of perception whereby S is said to perceive O just in case S stands in a psychological relation of acquaintance with O, where this relation is both non-representational and explanatorily primitive. For Marty however, all relations are non-real and, insofar as they are grounded, are neither fundamental, nor brute or primitive in an explanatory sense. I close by detailing what I thereby take a distinctively Martyan form of Naïve Realism to involve. The central theoretical tenet that phenomenal character is fundamentally constituted by worldly objects is preserved; but the manifestly relational structure of the acquaintance relation, construed in particular as a relation of awareness, is treated as derivative. I make headway in spelling out the latter claim by bringing Marty into fleeting conversation with another Thomist - G.E.M. Anscombe. (shrink)

We argue that the societal consequences of the scientific realism debate, in the context of science-to-public communication are often overlooked and careful theorizing about it needs further empirical groundwork. As such, we conducted a survey experiment with 130 academics (from physics, chemistry, and biology) and 137 science communicators. We provided them with an 11-item questionnaire probing their views of scientific realism and related concepts. Contra theoretical expectations, we find that (a) science communicators are generally more inclined towards scientific (...) antirealism when compared to scientists in the same academic fields, though both groups show an inclination towards realism and (b) academics who engage in more theoretical work are not less (or more) realist than experimentalists. Lastly, (c), we fail to find differences with respect to selective realism but find that science communicators are significantly less epistemically voluntarist compared to their academic counterparts. Overall, our results provide first empirical evidence on the views of scientists and science communicators on scientific realism, with some results running contra to the theoretical expectations, opening up new empirical and theoretical research directions.

The number of positions identified with structural realism in philosophical debates about scientific knowledge has grown significantly in the past decade, particularly with respect to the metaphysical or ‘ontic’ approach (OSR). In recent years, several advocates of OSR have proposed a novel understanding of it in order to side-step a serious challenge faced by its original formulation, eliminative OSR. I examine the conceptual basis of the new, noneliminative view, and conclude that it too faces a serious challenge, (...) resulting in a dilemma for ontic structuralists regarding the ontological status of objects and properties, and the relative “ontological priority” of these entities with respect to the relations in which they stand.

The depth-bounded approach seeks to provide realistic models of reasoners. Recognizing that most useful logics are idealizations in that they are either undecidable or likely to be intractable, the approach accounts for how they can be approximated in practice by resource-bounded agents. The approach has been applied to Classical Propositional Logic (CPL), yielding a hierarchy of tractable depth-bounded approximations to that logic, which in turn has been based on a KE/KI system. -/- This Thesis shows that the approach can be (...) naturally extended to useful nonclassical logics such as First-Degree Entailment (FDE), the Logic of Paradox (LP), Strong Kleene Logic (K3 ) and Intuitionistic Propositional Logic (IPL). To do this, we introduce a KE/KI-style system for each of those logics such that: is formulated via signed formulae, consist of linear operational rules and branching structural rule(s), can be used as a direct-proof and a refutation method, and is interesting independently of the approach in that it has an exponential speed-up on its tableau system counterpart. The latter given that we introduce a new class of examples which we prove to be hard for all tableau systems sharing the V/& rules with the classical one, but easy for their analogous KE-style systems. Then we focus on showing that each of our KE/KI-style systems naturally yields a hierarchy of tractable depth-bounded approximations to the respective logic, in terms of the maximum number of allowed nested applications of the branching rule(s). The rule(s) express(es) a generalized rule of bivalence, is (are) essentially cut rule(s) and govern(s) the manipulation of virtual information, which is information that an agent does not hold but she temporarily assumes as if she held it. Intuitively, the more virtual information needs to be invoked via the branching rule(s), the harder the inference is for the agent. So, the nested application the branching rule(s) provides a sensible measure of inferential depth. We also show that each hierarchy approximating FDE, LP, and K3 , admits of a 5-valued non-deterministic semantics; whereas, paving the way for a semantical characterization of the hierarchy approximating IPL, we provide a 3-valued non-deterministic semantics for the full logic that fixes the meaning of the connectives without appealing to “structural” conditions. -/- Moreover, we show a super-polynomial lower bound for the strongest possible version of clausal tableaux on the well-known class of “truly fat” expressions (which are easy for KE), settling a problem left open in the literature. Further, we investigate a hierarchy of tractable depth-bounded approximations to CPL based only on KE. Finally, we propose a refinement of the p-simulation relation which is adequate to establish positive results about the superiority of a system over another with respect to proof-search. (shrink)

In lieu of an abstract, here is a brief excerpt of the content:125. HUME ON PRIMARY AND SECONDARY QUALITIES Hume's view of the primary/secondary quality distinction is, I believe, a matter of considerable interest. It bears upon Hume's position in relation to Locke and Berkeley, and has important implications for general features of his epistemology and metaphysics. The central part of my discussion will therefore be taken up with a consideration of those passages from his writings in which Hume (...) refers to the primary/ secondary quality distinction. Hume's treatment of this aspect of the 'modern philosophy' may be seen against the background of his discussion of perception and its objects, and it is therefore this with which I begin. HUME'S SYSTEM I refer to Hume's system in relation to perception and the manner in which objects affect the senses. Hume's avowed purpose here is to discuss the way in which objects appear to the senses (in particular, those of sight and touch), rather than to account for their real nature and operations. Our ignorance of the nature of bodies reflects the fact that we are limited in experience to those properties of objects which discover themselves 2 to the senses. In determining the nature of Hume's system there are, I think, two (related) factors to be taken into account: (i) Hume's distinction between perceptions and objects; and (ii) Hume's critique of the Naive or Direct Realist theory of perception. (i) Perceptions and Objects The distinction which Hume wishes to make between perceptions and objects, and his general account of the relation between them, is embodied in his 126. discussion of the idea of external existence (T 6). We may observe, that 'tis universally allow'd by philosophers, and is besides pretty obvious of itself, that nothing is ever really present with the mind but its perceptions or impressions and· ideas, and that external objects become known to us only by the perceptions they 3 occasion. We should note that what Hume is describing here is, in essence, the Indirect Realist account of perception, i.e. that we are acquainted with an external reality only in the form of perceptions ('impressions') which arise from sensory contact with it. That Hume is prepared to speak elsewhere of per4 ceptions in their relation to external objects as images is indicative of his commitment to a Representative theory. There are, of course, severe limitations upon our understanding of the relation between perceptions and objects. As every idea is deriv'd from a preceding perception, 'tis impossible our idea of a perception, and that of an object or external existence can ever represent what are specifically different from each other. In so far as external objects are supposed to differ from perceptions in their specific identity, we can form only a relative idea of them (T 68). Nevertheless the idea of bodies or objects is clearly to be distinguished from that of perceptions; while being specifically the same, like ideas and impressions, these items, or rather the ideas involved, are attended with the supposition of a difference, that is unknown and incomprehensible (T 244). As different existences perceptions and objects may be conceived to differ in respect of their relational properties, for example, but otherwise whatever is true of the one must also be true of the other. These two sets of distinctions — between, on the one hand, ideas and impressions and, on the other, perceptions and objects — may usefully be compared and 127. contrasted. In each case the items with which we are concerned are numerically different but specifically identical; and, furthermore, the relation between the items which make up each pair is a causal one. The obvious difference between the two cases is that while both impressions and ideas are objects of experience, the causal dependence of the one upon the other being revealed by the order of their appearance before the mind, we do not directly experience external objects as opposed to perceptions. Questions concerning the 'real nature' of objects or bodies belong to the province of natural - rather than 'moral' - philosophy, which indeed has reasonable hypotheses to offer (T 48). As for our idea of body, this comprises nothing more than the ideas... (shrink)

Proponents of the view that social structures are ontologically distinct from the people in whose actions they are immanent have assumed that structures can stand in causal relations to individual practices. Were causality to be no more than Humean concomitance correlations between structure and practices would be unproblematic. But two prominent advocates of the ontological account of structures, Bhaskar and Giddens, have also espoused a powers theory of causality. According to that theory causation is brought about by the (...) activity of particulars, in the social psychological case, individuals of some sort. Consistence would demand that structure be those individuals. But neither Giddens nor Bhaskar wish to reify structure to the extent that would fit it for a role as a powerful particular. If only human beings can be powerful particulars in these contexts, the only way that structures can be real must be as properties of conversational interactions. Human action is social just in so far as people direct themselves to engage well in joint activities with others. (shrink)

Extending the ideas from (Hofer-Szabó and Rédei [2006]), we introduce the notion of causal up-to-n-closedness of probability spaces. A probability space is said to be causally up-to-n-closed with respect to a relation of independence R_ind iff for any pair of correlated events belonging to R_ind the space provides a common cause or a common cause system of size at most n. We prove that a finite classical probability space is causally up-to-3-closed w.r.t. the relation of logical independence (...) iff its probability measure is constant on the set of atoms of non-0 probability. (The latter condition is a weakening of the notion of measure uniformity.) Other independence relations are also considered. (shrink)

In the last 20 years, a stream of research emerged under the label of „complex problem solving“ (CPS). This research was intended to describe the way people deal with complex, dynamic, and intransparent situations. Complex computer-simulated scenarios were as stimulus material in psychological experiments. This line of research lead to subtle insights into the way how people deal with complexity and uncertainty. Besides these knowledge-rich, realistic, intransparent, complex, dynamic scenarios with many variables, a second line of research (...) used more simple, knowledge-lean scenarios with a low number of variables („minimal complex systems“, MCS) that have been proposed recently in problem-solving research for the purpose of educational assessment. In both cases, the idea behind the use of microworlds is to increase validity of problem solving tasks by presenting interactive environments that can be explored and controlled by participants while pursuing certain action goals. The main argument presented here is: both types of systems - CPS and MCS – can only be dealt with successfully if causal dependencies between input and output variables are identified and used for system control. System knowledge is necessary for control and intervention. But CPS and MCS differ in their way of how causal dependencies are identified and how the mental model is constructed; therefore, they cannot be compared directly to each other with respect to the cognitive processes that are necessary for solving the tasks. Knowledge-poor MCS tasks address only a small fraction of the cognitive processes and structures needed for knowledge-rich CPS situations. (shrink)

The main aim of this thesis is to defend moral realism. In chapter 1, I argue that moral realism is best understood as the view that moral sentences have truth-value, there are moral properties that make some moral sentences true, and moral properties are not reducible to non- moral properties. Realism is contrasted with non-cognitivism, error-theory and reductionism, which, in brief, deny, and, respectively. In the introductory chapter, it is also argued that there are some prima facie reasons to (...) assume that non-cognitivism and error-theory are erroneous. In chapters 2 and 3, I suggest that the two main forms of reductionism, analytic and synthetic reductionism, are mistaken. In chapter 4, I argue that the considerations in the previous chapters in relation to non-cognitivism, error-theory and reductionism provide support to moral realism. It is also suggested that these considerations make it plausible to hypothesise that moral properties depend on non- moral properties in a way I refer to as ‘the realist formula’. The realist formula confirms moral realism since it implies that moral properties are not reducible to non- moral properties. In chapters 5, 6 and 7, I argue that moral realism, much owing to the realist formula, is able to explain significant meta-ethical issues regarding moral disagreement, moral reason and moral motivation. Among other things, externalism concerning moral motivation is defended. The explanatory value of moral realism in relation to these meta-ethical issues is taken to suggest that this view is preferable to non-cognitivism, error-theory and reductionism. Some of the meta-ethical issues discussed in these chapters, particularly moral disagreement and motivation, have been thought to provide support to non-cognitivism and error-theory. I maintain that since realism, unlike reductionism, is able to counter these arguments, it justifies us in upholding the view that moral sentences have truth-value and the view that there are moral properties. In chapter 8, various objections against realism with regard to the dependence of moral properties on non- moral properties are responded to. In chapter 9, I consider an influential argument to the effect that moral properties are not involved in causal explanations. I maintain that this argument fails and that it therefore is reasonable to assume that moral properties are natural properties. However, the discussions in chapters 8 and 9 also suggest that moral realism might face problems that cannot be thoroughly discussed in this thesis. (shrink)

Positivists and phenomenalists of all sorts maintain, and long have maintained, some variant of the following thesis concerning the existence of physical objects: Such statements as ‘There is now a wall behind my back’ are synonymous with a class of statements of which the following is representative ‘If I shall turn my head, then I shall also have the visual experience called ‘seeing a wall'.’ This amounts to proposing what many of us call a philosophical analysis of ‘exist’ or, (...) more precisely, of one meaning of ‘exist'; for the thesis implies that this verb, in the sense in which we use it when we say ‘This wall exists', is dispensable in the sense of being definable. Realists, who oppose the thesis, hold that ‘exist', in the sense mentioned, is what I would call an undefined descriptive predicate; and then they go on to recommend that instead of defining existence in terms of what we see, we had better say that we shall, if we turn, see a wall because there is a wall. Thus one could say, perhaps, that the realists wish to convert the positivistic position; instead of founding existence upon experience, they want to found experience upon existence. To be sure, this is but a bare and crudely formulated schema of an issue that has been argued for a long time. Also, contemporary analysts for the most part do not discuss the issue directly; they give their attention to preliminary and, therefore, more fundamental questions. Like experienced chess players, who know to which characteristic situations in the middle game certain openings will eventually lead, we try to convince each other of the excellence of our respective openings. There is, in particular, one fundamental or opening move that is now widely discussed and which, I believe, most of us examine with a view to the position in which we shall find ourselves—in the middle game—with respect to the realism issue. I refer to the clarification of the relations between meaning and verification or, to put it the way positivists do, to the formulation of an adequate meaning criterion. Let me indicate the connection between these questions and the crude schema I have given for the realism issue. According to current garden varieties of positivism, a statement is meaningful if it is verifiable by experience. ‘There is a wall behind my back’ is, in this view, meaningful because it is synonymous with a class of statements each of which is verifiable by future experience. More pointedly, the familiar common sense statements about the existence of physical objects are considered as meaningful because they are verifiable. This has again the subjectivistic ring realists dislike so much; so they may again be inclined to convert the positivistic position, if only tentatively and because they feel that a piece of realistic common sense would thus be preserved. But to make the conversion is to say that ‘There is a wall behind my back’ is verifiable because it is meaningful. (shrink)

Finding out which terms – scientific or otherwise— fail to refer is an extremely complex business since both felicitous reference and failure to refer must be negotiated. Causal theories of reference –even so-called hybrid theories – posit that in order to refer to something, we need the regulative idea of an ontological reference, which operates even when we refer to impossibilia or inconceivable objects. Evidently, this is not the case of the referent of phlogiston, which is neither inconceivable nor (...) impossible, nor, alas, does it exist. In the antipodes, from a representational-physicalist point of departure, a term fails to refer if it has no actual ontological grounds: phlogiston fails to refer because it has no physical existence. Phlogiston can even be considered to be a fictional entity, and referring to a fictional entity is not the same as a reference in a fiction or a fictional reference Salmon : a fictional entity is an object in the same sense as an abstract object, and therefore we can genuinely refer to it. The question is: who claims that phlogiston does not exist? Nowadays, everyone does, fundamentally and primarily because science has established it as a fact. The process that led to this result is extremely complex, lengthy and multi-dimensional. It involved factors of several kinds: cognitive, social, political, historical, as well as ontological, and this last factor has been neglected. I do not claim that phlogiston once existed and then ceased to exist -- science only allows us a sneak-peek into what exists and what, sometimes mistakenly, is supposed to exist. Paraphrasing Latour, this inquiry is about following the journey of the referents, even when they do not end up being physical-existent or existing objects. I believe with Bach that the notion of reference is essentially pragmatic; that the difference between alluding to something and referring to or denoting something must be established; that to achieve this the semantic properties of terms are not sufficient, and finally that references are not semantic but cognitive properties that relate thoughts and objects of any kind. My assumption is that to refer to something one must be capable of having thoughts about it and that the propositions one attempts to communicate in the course of referring to it are singular with respect to it. Being in a position to have a thought about a particular thing requires being connected to that thing, via perception, memory, communication and/ or education. Therefore, only in an exceedingly narrow realist theory of reference does phlogiston fail to refer. Unless a theory of reference of scientific terms is based on the study of the actual linguistic communicative practices among scientists, it will inevitably pose serious epistemological difficulties.

We examine three business-related initiatives designed to achieve peace positive impacts in the Cape Town township of Langa. Each was seemingly straightforward in its purpose, logic, and implementation. However, their positive intent was frustrated and their impacts ultimately harmful to their articulated goals. Understanding why this is so can be difficult in violent, turbulent, and information-poor environments such as Langa, confounding progress even by actors with ethical intentions. To aid in sense making and to provide insight for more positive (...) future action, we develop from 125 interviews conducted for this study causal loop models for these initiatives within their conflict subsystems. These explain the perverse impacts of these initiatives by illuminating their (lack of) salience to key conflict factors, their (in)sufficiency to effect positive change in light of competing systems dynamics, and their (in)attentiveness to interdependencies with the intentions and actions of others. We thus contribute to understanding of the factors required to achieve positive social outcomes in more extreme contexts. More generally, we demonstrate the value of systems analysis both for scholarship related to business and peace and for reducing blind spots that can inhibit sound planning for ethical business action amidst complexity.

Abstract:This paper places the debate on intrinsic value taking place in environmental ethics within the context of the traditional controversy between realism and antirealism. It lays the groundwork for a new kind of realism with respect to intrinsic value. The latter does not claim that intrinsic value is real in the sense that it exists in an external, mind-independent reality; nor does it claim that that there are objective truthmakers of valuing statements. First, it aims at acts of (...) valuing instead of values. So, the question is whether there are cases in which something merits an act of intrinsic valuing. We propose that the core of realism with regard to intrinsic value is the endorsement of what might be is provisionally called the axiological rule of excluded middle; it says that for a given subject or group of subjects any entity either merits an act of intrinsic valuing or does not. However, for the proposed account to work, the paper also seeks a new account of meriting an act of valuing itself, endowing this specific relation with a new, more "embodied" sense. (shrink)

I argue that scientific and poetic modes of objectivity are perspectival duals: 'views' from and onto basic natural forces, respectively. I ground this analysis in a general account of objectivity, not in terms of either 'universal' or 'inter-subjective' validity, but as receptivity to basic features of reality. Contra traditionalists, bare truth, factual knowledge, and universally valid representation are not inherently valuable. But modern critics who focus primarily on the self-expressive aspect of science are also wrong to claim that our knowledge (...) is or should be ultimately mediated by ourselves. In objective science, we represent nature as a field of phenomena determined by and within explanatorily-basic physical structures that encode the causal impact of elemental physical forces. These causally-basic forces hence ground the possibility of objective scientific theory, even though (I argue) they are systematically excluded from its representational contents. I show how my notions of force and field emerge partly through my effort to naturalize concepts of 'God' and 'Laws' in 17th-century natural philosophy. In science, we use the structure of basic forces' impact to see corresponding objects. We do not see these forces themselves—and this relates to the 'transcendence' of 'God'. I supplement this historical analysis by critiquing standard accounts of objectivity, and by synthesizing elements from neo-Kantian epistemology and current 'structural' realism into a view that I call 'dynamic structuralism'. Finally, I argue that physics systematically relies on passive characterizations of phenomena like inertia and impressed force. Dynamic alternatives that are just as empirically adequate are possible, but they are non-scientific. Poetic objectivity involves a direct presentation of nature as an order of interacting forces. I elaborate first by developing a novel theory of the relation between beauty and sublimity, mediated by a basic category of 'sensory force' (e.g. a 'singing' tone in a beautiful melody). I then describe the interaction between sensory and affective dimensions of aesthetic experience, in relation to an original historical analysis of passion and 'disinterestedness' in Kant, Schiller and Nietzsche. I synthesize these lines of analysis into a critique of the role of 'expression' in art. I also resist 'spectator'-centric aesthetics, in this connection, by developing an account of artistic objectivity in dialogue with Ruskin's critique of the 'pathetic fallacy'. I contrast artistic objectivity with Romantic ideals of self-expression, while elaborating its positive relation to certain currents within Victorian and Modernist aesthetics, including Imagists' stress on 'exteriority'. My project creatively extends Nietzsche's view that philosophical and scientific theories are 'perspectival' expressions of theorists' drives. It is a virtue of Nietzsche's account that he takes the outlet of strong human drives in creative acts of theorizing to be just one among many higher modes of 'will to power' in nature—many of which are totally impersonal. But Nietzsche is still too focused on self-expression or willing one's own power. Objective science involves external forces' 'expression' in and through us, not just 'expressing' our own powers. And Nietzsche's vitalistic 'will to power' must be replaced by a basic ontology that better accommodates inorganic phenomena, like the 'lawful' order of celestial motions. Thus I aim to de-anthropomorphize and 'de-organicize' post-Kantian notions of willful striving and organic development, while preserving for force the primary ontological and evaluative status that theorists from Schiller and Goethe to Schelling and Schlegel to Emerson and Nietzsche attributed to will or to life.

In this paper, I outline a disjunctivist proposal for understanding the intentionality of perceptions and hallucinations within a naïve realist framework. For the case of genuine perceptual experience, naïve realists can endorse a version of the view that their intentionality is phenomenally-grounded: perceptual experiences have intentionality in virtue of being relations of conscious acquaintance to aspects of the mind-independent environment. By contrast, hallucinations have intentionality dependently or derivatively, in virtue of their indiscriminability from, or similarity with respect (...) to, perceptual experiences. Within this proposal, naïve realists can allow that perceptions and hallucinations have a property in common – that of being intentionally directed at apparently mind-independent entities – whilst having wholly different metaphysical natures.

In the years spanning the first half of the 20th century Bertrand Russell wavered between two incompatible accounts of physical reality. On one account, physical objects were taken to be logical constructs of phenomenal entities, the immediate data of sense experience. Such a view roughly fits the familiar characterization of being a combination of “Hume plus mathematical logic.” This type of phenomenalism, in the empiricist tradition, contrasted starkly with a variant of scientific realism, including a realistic account of (...) class='Hi'>causal connections as relations between universals, that Russell developed between 1912 and 1927, and which was derived from Kant’s distinction between a noumenal and a phenomenal world. My concern in this paper is with the viability of the unique form of scientific realism Russell developed, the role of universals and causal explanation in it, and criticisms that have been directed at it. I will argue that an early refutation of Russell’s realism by the mathematician M. Newman and a recent revival of that refutation by W. Demopoulos and M. Friedman ignore the critical role universals play in Russell’s scientific realism and hence fail to refute his view. I will also briefly consider a recent “anti-realist” argument that repeats Newman’s mistake: interpreting predicates in terms of extensions and not as referring to universal properties and relations.

This provocative but persuasive book is essentially a radical attack upon the Humean conception of causality and the presentation and defense of a counter-theory, closer to everyday experience and pre-Humean traditional views. As formulated by empiricist philosophers, the Humean approach depends on two basic postulates. The philosophical analysis of any non-empirical concept must be a formal explication; any residue elements have to be accounted for in terms of their psychological origins. The world as experienced can be conceived adequately as a (...) logically independent system of things or flux of events, without the unwarranted assumption that individuals persist diachronically. As the grounds for undermining these assumptions, the authors develop a conception of causes as "powerful particulars," i.e., things which have both a nature and powers. So long as the nature remains unchanged the agent in question will continue to behave in this fashion with a natural necessity, stemming from the individual’s nature and specific powers. The opening chapter discusses the problem of conceptual and natural necessity—as distinct from logical necessity which alone is allowed by the Humean empiricists. Natural necessity is the mark of the relationship between real causes and their respective effects, whereas conceptual necessity characterizes the way our statements about such are themselves related. Later the irreducibility of natural necessity is emphasized and its differences from logical entailment spelled out. Chapter two takes up the subject of the "regularity theory and its allies." Characteristic of such are two claims: the empirical content of a causal-relationship statement is exhausted by the actual or hypothetical regularity between independent entities, and the necessity ordinarily attributed to causal production is an illusion, to be accounted for in various ways. Subsequent chapters are devoted to assaulting the pillars of the Humean notion either directly or indirectly through an illuminating and attractive account of their own theory of nature, causal powers, and natural necessity. The final chapter, entitled "Fields of Potential," indulges in speculation about the nature of ultimate entities on the basis of an extended generalization of the notion of the powerful individual, and concludes with a brief account of the historical antecedents of Faraday’s modern field theory and the metaphysical implications of a generalized field theory.—A.B.W.

Macroscopic irreversible processes emerge from fundamental physical laws of reversible character. The source of the local irreversibility seems to be not in the laws themselves but in the initial and boundary conditions of the equations that represent the laws. In this work we propose that the screening of currents by black hole event horizons determines, locally, a preferred direction for the flux of electromagnetic energy. We study the growth of black hole event horizons due to the cosmological expansion and accretion (...) of cosmic microwave background radiation, for different cosmological models. We propose generalized McVittie co-moving metrics and integrate the rate of accretion of cosmic microwave background radiation onto a supermassive black hole over cosmic time. We find that for flat, open, and closed Friedmann cosmological models, the ratio of the total area of the black hole event horizons with respect to the area of a radial co-moving space-like hypersurface always increases. Since accretion of cosmic radiation sets an absolute lower limit to the total matter accreted by black holes, this implies that the causal past and future are not mirror symmetric for any spacetime event. The asymmetry causes a net Poynting flux in the global future direction; the latter is in turn related to the ever increasing thermodynamic entropy. Thus, we expose a connection between four different “time arrows”: cosmological, electromagnetic, gravitational, and thermodynamic. (shrink)

In lieu of an abstract, here is a brief excerpt of the content:138 HUME AND WITTGENSTEIN: CRITERIA VS. SKEPTICISM As far as philosophical admonitions go, there are probably few as famous as Wittgenstein's Blue Book warning: We are up against one of the great sources of philosophical bewilderment : we try to find a substance for a substantive, (p. 1) Wittgenstein, of course, could have added: This is something we should have learned long ago from Hume. He could have quoted (...) the following passage from the Appendix to the Treatise: Philosophers begin to be reconcil'd to the principle, that we have no idea of external substance, distinct from the ideas of particular qualities. This must pave the way for a like principle with regard to the mind, that we have no notion of it, distinct from the particular perceptions. Neither causal necessitation, self, nor substances could be located by Hume no matter how hard he tried to analyse his experience of the world. For Hume, there were no experiential 'facts-of-thematter ' in virtue of which one could acknowledge, with epistemic justification, causal connectivity or necessity, the temporal extension of one's own mind, or the elusive particularity of that in which qualities are sometimes said to inhere. We know that for Hume, since he tells us, his skepticism is engendered by his inability to surrender either of the two principles, the conjunction of which he takes to be impossible. He is unable to deny that whatever is distinguishable is separable, and, as well, that there are de re connections between what is distinguishable. (T 636) What this means for Hume is that the world 'as it really is' could well be utter- 139 Iy chaotic, or, at least, structured by relations and connections which bear no resemblance to the relations and connections imposed upon our perceptions and subsequently projected onto the world. Hume, of course, is neither the disputatious sort of ersatz skeptic at whom he sneers in the opening paragraphs of An Enquiry Concerning the Principles of Morals; nor is he a fainthearted skeptic, who will, in the end, return to us everything he had only seemed to take away. We know just how unrelenting he is in his attempt to show that "the understanding never observes any real connexion among objects, and that even the union of cause and effect, when strictly examin'd, resolves itself into a customary association of ideas." (T 259-260) Although Book I of the Treatise is called "Of the Understanding," misunderstanding is not a topic that exercises Hume. Of course, it is not all that difficult to understand why this is so. 'Misunderstanding ' is, on its semantic face, inseparably concerned with language; and a concern for and about language is not something that attracts very much of Hume's explicit attention. Indeed, I am inclined to think that Hume's most important explicit comment about language is to be found in Book II, where he notes:...the sense of interest has become common to all our fellows, and gives us a confidence of the future regularity of their conduct: And 'tis only on the expectation of this, that our moderation and abstinence are founded. In like manner are languages gradually establish'd by human conventions without any promise. (T 490) 140 In Wittgensteinian terms, I think that Hume is saying, in effect, that the conventions that determine what is just with respect to property in a society are, as it were, definitive of a form of social life; that is, not agreements, contracts, or compacts — promises, as Hume refers to these — since such compacts are themselves embedded in something deeper, namely, in the human conventions that ground such compacts and contracts. Although I am going beyond what Hume says here, there is no reason to believe that we cannot identify the analogical linguistic counterparts of promises and conventions. The linguistic conventions provide the foundational matrix for the applicability of the justifying truth-making procedures. In essence, sense precedes, and determines, truth conditions. What I will argue for here is the view that it is impossible for Wittgenstein to have been a skeptic of a Humean variety; since such skepticism presupposes realism; and, whatever else Wittgenstein is, or isn't, he is not...

What distinguishes philosophy is its attention to reality and sense as such, or what is traditionally called being and essence. As a result, philosophy as a way of life is, most fundamentally, not directly a matter of doing one kind of thing rather than another outside the classroom but instead of how we live with respect to our being. Enacting our being in one way rather than another inflects whatever it is we do. Consequently, even if we only (...) study philosophy in the conventional, apparently unlived way in the classroom, we are in active relation to our being and therefore fully living philosophy as a way of life.

In this paper I call attention to the fact that Lonergan gives two radically opposed accounts of how sense perception relates us to the external world and of how we know that this relation exists. I argue that the position that Lonergan characteristically adopts is not the one implied by what is most fundamental in his theory of cognition. I describe the initial epistemic position with regard to the problem of skepticism about the external material world that is in (...) fact implied by his theory of cognition, and I sort out some confusion about various forms of direct and representative perceptual realism. The paper concludes with a critique of Lonergan’s theory of description and explanation in empirical science that makes evident the difficulties into which he is led by lack of clarity in his theory of perception.

Bell's theorem is believed to establish that the quantum mechanical predictions do not generally admit a causal representation compatible with Einsten's principle of separability, thereby proving incompatibility between quantum mechanics and relativity. This interpretation is contested via two convergent approaches which lead to a sharp distinction between quantum nonseparability and violation of Einstein's theory of relativity.In a first approach we explicate from the quantum mechanical formalism a concept of “reflected dependence.” Founded on this concept, we produce a (...) class='Hi'>causal representation of the quantum mechanical probability measure involved in Bell's proof, which is clearly separable in Einstein's sense, i.e., it does not involve supraluminal velocities, and nevertheless is “nonlocal” in Bell's sense. So Bell locality and Einstein separability aredistinct qualifications, and Bell nonlocality (or Bell nonseparability) and Einstein separability arenot incompatible. It is then proved explicitly that with respect to the mentioned representation Bell's derivation does not hold. So Bell's derivation does notestablish thatany Einstein-separable representation is incompatible with quantum mechanics. This first—negative—conclusion is asyntactic fact.The characteristics of the representation and of the reasoning involved in the mentioned counterexample to the usual interpretation of Bell's theorem suggest that the representation used—notwithstanding its ability to bring forth the specified syntactic fact—isnot factually true. Factual truth and syntactic properties also have to be radically distinguished in their turn. So, in a second approach, starting from de Broglie's initial relativistic model of a microsystem, a deeper, factually acceptable representation is constructed. The analyses leading to this second representation show that quantum mechanics does indeed involve basically a certain sort of nonseparability, called here de Broglie-Bohr quantum nonseparability. But the de Broglie-Bohr quantum nonseparability is shown to stem directly from the relativistic character of the considerations which led Louis de Broglie to the fundamental relation p = h/λ,thereby being essentially consistent with relativity. As to Einstein separability, it appears to be a still insufficiently specified conceptof which a future, improved specification, will probably be explicitly harmonizable with the de Broglie-Bohr quantum nonseparability.The ensemble of the conclusions obtained here brings forth a new concept of causality, a concept offolded, zigzag, reflexive causality, with respect to which the type of causality conceived of up to now appears as aparticular case of outstretched, one-way causality. The reflexive causality is found compatible with the results of Aspect's experiment, and it suggests new experiments.Considered globally, the conclusions obtained in the present work might convert the conceptual situation created by Bell's proof into a process of unification of quantum mechanics and relativity.

if and only if for every W in V, W is independent of the set of all its non-descendants conditional on the set of its parents. One natural question that arises with respect to DAGs is when two DAGs are “statistically equivalent”. One interesting sense of “statistical equivalence” is “d-separation equivalence” (explained in more detail below.) In the case of DAGs, d-separation equivalence is also corresponds to a variety of other natural senses of statistical equivalence (such as representing (...) the same set of distributions). Theorems characterizing d-separation equivalence for directed acyclic graphs and that can be used as the basis for polynomial time algorithms for checking d-separation equivalence were provided by Verma and Pearl (1990), and Frydenberg (1990). The question we will examine is how to extend these results to cases where a DAG may have latent (unmeasured) variables or selection bias (i.e. some of the variables in the DAG have been conditioned on.) D-separation equivalence is of interest in part because there are algorithms for constructing DAGs with latent variables and selection bias that are based on observed conditional independence relations. For this class of algorithms, it is impossible to determine which of two d-separation equivalent causal structures generated a given probability distribution, given only the set of conditional independence and dependence relations true of the observed distribution. We will describe a polynomial (in the number of vertices) time algorithm for determining when two DAGs which may have latent variables or selection bias are d-separation equivalent. (shrink)

In lieu of an abstract, here is a brief excerpt of the content:176 HISTORY OF PHILOSOPHY to be accounted for in some way. Goldsmith takes no cognizance of these categorical statements. Secondly, there is no support for Goldsmith's conclusion to be found in Hobbes's comment at the end of De Corpore. A cursory reading of the passage makes it clear that the comments concerning other hypotheses refer only to Part IV of De Corpore and not to the whole system as (...) Goldsmith suggests. Indeed the earlier parts are said to comprise the "theorems" of the systems, and the only way Hobbes suggests they might be found corrigible is if a mistake in deduction has occurred. Finally, Goldsmith pays insufficient attention to Hobbes's account of the process of analysis and sometimes seems to confuse it with the imaginary annihilation of the world which Hobbes uses as an expository device in expounding his concept of space. As Hobbes describes the process it begins with a phenomenal whole which is subjected to continued conceptual analysis until unanalyzable elements are reached. These logically primitive notions are referred to by Hobbes as "the most universal things" and as "first principles" which are "manifest of themselves" or "known to nature" (E. W. I, 69), all of which strongly suggests that they are coguized and not simply posited. Goldsmith mentions these descriptions of Hobbes's first principles in Chapter I, but presents no arguments to justify his abandoning them in favor of "suppositions or assumptions." When Goldsmith moves to Hobbes's political theory, he is on much firmer ground. The sections concerning human nature and natural law are generally excellent, particularly the account in Chapter IV of the relations between the various laws of nature. The treatment throughout this part of the book is exhaustive, although the point of some extended discussions is not very clear. There is a long discursive section in Chapter v on contraetarian thought which seems quite unrelated to anything it follows or precedes. And there are some curious allotments of emphasis. While Hobbes's "economic policy," which is a peripheral matter, is given a section to itself, the concept of obligation, which has been the focus of so much dispute in recent years and which is a central concern, is dealt with only by implication and in passing. In general Goldsmith accepts the traditional interpretation which sees the laws of nature as primarily prudential precepts found out by reason. These precepts are said to be like the "laws" of physics with respect to man's behavior in that they indicate regularities about the world which are ignored at one's own risk. Goldsmith suggests that the possible knowledge of God as a first cause serves only to reinforce man's awareness of the total causal nexus. The laws of nature are, properly speaking, laws only when they become civil regulations under the authority of a sovereign. The final chapter of the book attempts to assess the success of Hobbes's endeavor to create a science of politics by the "test" of its ability to explain the political phenomena of law, religion, and history. This is followed by eight appendices in which various disputes with other interpreters are briefly argued. The book contains an adequate index and a selected bibliography.

The following is an assessment of critical realism, a philosophy of science advanced in the mid-1970s to mid-1980s by Roy Bhaskar. My contention is that critical realism points toward a way out of the post-positivist intellectual morass in which we currently find ourselves. ;I identify two challenges posed by proponents of what I refer to as post-positivist perspectivism: epistemic relativism and the anti-realism that relativism presupposes. I take these challenges to have political implications, in that both undermine our capacity to (...) talk seriously about falsehood. I argue that critical realism is most valuable as a non-Humean account of causality. As such it provides for a direct counter to anti-realism and an indirect counter to epistemic relativism. ;I attempt to determine the significance of critical realism by engaging with a set of representative interlocutors: Kant, Hilary Putnam, Charles Varela and Rom Harre, Brian Ellis and, to a limited extent, Charles Taylor. Following an introductory chapter, in which I set out Bhaskar's position, I devote a chapter to Kant's transcendental idealism, a chapter to Hilary Putnam's internal realism, a chapter to Bhaskar's theory of truth and a chapter to Bhaskar's extension of his views to the social and psychological sciences. In the chapter on Bhaskar's philosophy of social and psychological science I respond to objections raised by Charles Varela and Rom Harre in relation to the causal efficacy of social structures, and to objections raised to the general position, articulated by Brian Ellis. I also raise certain concerns of my own regarding Bhaskar's conceptualization of the efficacy of reasons and his treatment of actions. I conclude by reflecting, in a final chapter, on the significance of Bhaskar's work in relation to the challenges of relativism and anti-realism. (shrink)

This paper examines pain states (and other intransitive bodily sensations) from the perspective of the problems they pose for pure informational/representational approaches to naturalizing qualia. I start with a comprehensive critical and quasi-historical discussion of so-called Perceptual Theories of Pain (e.g., Armstrong, Pitcher), as these were the natural predecessors of the more modern direct realist views. I describe the theoretical backdrop (indirect realism, sense-data theories) against which the perceptual theories were developed. The conclusion drawn is that pure representationalism (...) about pain in the tradition of direct realist perceptual theories (e.g., Dretske, Tye) leaves out something crucial about the phenomenology of pain experiences, namely, their affective character. I touch upon the role that introspection plays in such representationalist views, and indicate how it contributes to the source of their trouble vis-à-vis bodily sensations. The paper ends by briefly commenting on the relation between the affective/evaluative component of pain and the hedonic valence of emotions. (shrink)

This book provides a post-positivist theory of deterministic and probabilistic causality that supports both quantitative and qualitative explanations. Features of particular interest include the ability to provide true explanations in contexts where our knowledge is incomplete, a systematic interpretation of causal modeling techniques in the social sciences, and a direct realist view of causal relations that is compatible with a liberal empiricism. The book should be of wide interest to both philosophers and scientists. Originally published (...) in 1989.

Geography has traditionally been assigned the role of handmaiden in evolutionary studies. In this work a different understanding of the relationship between biological change and locational setting is developed: evolution as a dynamic form of spatial interaction. In the causal model presented, adaptive change is portrayed as a negative feedback response contributing to a general spatial-temporal process of resource cycle tightening involving exchanges between the two fundamental structural sectors (abiotic and biotic) of the earth's surface system. As such, it (...) is rejected as evolution per se. This position makes it possible to circumvent the adaptation yields adaptation circularity, and to view locational circumstances as being evolutionarily causal, yet not deterministic with respect to population-level change. A parallel interpretation of the relation between range and range change and evolution is also implicit; the individualistic hypothesis is thereby superceded by a model of community evolution allowing for individualistic rates of population (adaptive and) range change, but operating on the principle that populations should tend to change range in common directions (as a response to spatially-varying degrees of efficiency of turnover of resources vital to biotic sector function). This in turn leads to the possibility of normative biogeographic modelling. Comment is also made on the relationship of the present understanding to disequilibrium and dynamic equilibrium interpretations of evolutionary change, and to human cultural evolution. (shrink)

The purpose of this review article is to offer a criticism of the interpretation of Duns Scotus’s conception of intelligible being that has been proposed by Michael Renemann in his book Gedanken als Wirkursachen. In the first place, the author shows that according to Scotus, for God “to produce a thing in intelligible being” and “to conceive a thing” amounts to altogether one and the same act. Esse intelligibile therefore does not have “priority of nature” with respect to (...) “esse intellectum” or “esse repraesentatum”, contrary to Renemann’s interpretation. The distinction between Scotus’s second and third “instants of nature” consists in something else, then: the relation of reason, of which Scotus says that it is produced in the third instant, is not the relation of being actually conceived (first, because actual intellection comes already in the second instant, and second, because divine intellection, being the measure of the conceived objects, is not relative bud absolute) but it is a relation of comparison, viz. of an image to its exemplar. Next, the author shows how a misreading of two passages of Scotus’s Ordinatio misled both the Vatican editors and Renemann to create the chimaera of “verum esse secundum quid”. By way of a conclusion the author argues that Scotus’s doctrine of “esse intelligibile” does not make him any less a direct realist than Suárez, his position being quite plausible even from the point of view of common sense.

Social network analysis (SNA) is an increasingly popular approach that provides researchers with highly developed tools to map and analyze complexes of social relations. Although a number of network scholars have explicated the assumptions that underpin SNA, the approach has yet to be discussed in relation to established philosophies of science. This article argues that there is a tension between applied and methods-oriented SNA studies, on the one hand, and those addressing the social-theoretical nature and implications of networks, (...) on the other. The former, in many cases, exhibits positivist tendencies, whereas the latter incorporate a number of assumptions that are directly compatible with core critical realist views on the nature of social reality and knowledge. This article suggests that SNA may be detached from positivist social science and come to constitute a valuable instrument in the critical realist toolbox. (shrink)

Great scholars in philosophy possess a keen analytical mind, excel in logical reasoning, and exhibit meticulous attention to detail. They rigorously define terms, avoiding ambiguities and errors. Originality and the willingness to challenge conventions are their hallmarks. They make significant contributions across various philosophical fields. They transparently address the exact aim of their research, and what it is not. Finally, they anticipate the impact of their theories on the current literature, and how such an impact should blossom across the future (...) generations. In this respect, great philosophers address open problems and propose big questions for the foreseeable research efforts of those who will follow. Mario Alai embodies the qualities of a great scholar in philosophy, and the various essays in this volume are an evidence to that. It is challenging to condense a lifetime of research in one book. However, the Editors of the present volume’s aim was to face this challenge, to make a collection dedicated to Mario Alai’s work not only possible but, as metaphysicians would say, actual. The book attempts to bring together the reflections of three different generations of scholars - i.e., mentors, colleagues, and students - on Alai’s thought. Viewed from this perspective, the extensive and valuable contributions that follow, crafted in honor of Mario Alai and his scholarly endeavors, come as no surprise. All the chapters focus on a theme that was very dear to the philosophical curiosity of Mario Alai. Moreover, in engaging with these different topics, the plethora of contributions gives us a sense of the work by Alai. To make sense of the different contributions as a unified enterprise, this volume is organized into three sections, which seek to gather writings that revolve around Mario’s most substantial contributions, while elucidating their contemporary significance in the global discourse. Moreover, it endeavors to offer precious insights into the origins and development of these contributions, as observed through Mario’s writings and responses. This represents a sort of closure of the theoretical circle, clearly showing how the work by Mario Alai has been appreciated through different generations, originating from his relation to his mentors, on the one hand, while also shedding new light on his students’ research interests, on the other. Editing such a wealth of material was, again, no small feat. Still, the taxonomy we have chosen for this book will assist readers in navigating the profound depths of Alai’s philosophical research. Consequently, the book is structured into the following three parts: 1. Realism in History of Philosophy, History of Science, and Metaphysics. 2. Scientific Realism. 3. Realism in Philosophy of Language, Epistemology, and Experimental Philosophy. Each contribution actively participates in a substantial conversation with Alai’s body of work, as a deep theoretical dialogue between the author and Mario. Consequently, it appeared fitting to let Alai conclude this conversation, with direct responses to these philosophy-provoking pieces in his honor. We shall refrain from further commentary on the works within this book and allow them to express their significance independently to appreciate the river of ideas flowing through Mario’s work1. Beyond their philosophical substance, they are a vivid testament to Alai’s enduring dedication and ongoing contributions, in different moments of his research life. (shrink)

The most common form of direct realism is Phenomenological Direct Realism (PDR). PDR is the theory that direct realism consists in unmediated awareness of the external object in the form of unmediated awareness of its relevant properties. I contrast this with Semantic Direct Realism (SDR), the theory that perceptual experience puts you in direct cognitive contact with external objects but does so without the unmediated awareness of the objects’ intrinsic properties invoked by PDR. (...) PDR is what most understand by direct realism. My argument is that, under pressure from the arguments from illusion and hallucination, defenders of intentionalist theories, and even of relational theories, in fact retreat to SDR. I also argue briefly that the sense-datum theory is compatible with SDR and so nothing is gained by adopting either of the more fashionable theories. (shrink)

In the last decade, several researchers have proposed theories of actual causation that make use of structural equations and directed graphs. Many of these researchers are committed to a widely-endorsed folk attribution desideratum, according to which an important constraint on the acceptability of a theory of actual causation is agreement between the deliverances of the theory with respect to specific cases and the reports of untutored individuals about those same cases. In the present article, we consider a small (...) collection of related theories of actual causation, including a purely structural theory and two theories that supplement the structural equations with considerations of defaults, typicality, and normality. We argue that each of these three theories are meant to satisfy the FAD, and then we present empirical evidence that they fail to do so for several variations on a simple scenario from the literature. Drawing on our previous work on the responsibility view of folk causal attribitons, we conclude by offering a solution that allows the latter two theories to satisfy the FAD for these cases. The solution is to give up on concerns with typicality and focus on injunctive norms in supplementing the graphical modeling machinery. (shrink)

Thomas Reid famously claimed that our perceptual experiences reveal what primary qualities are in themselves, while providing us with only an obscure notion of secondary qualities. I maintain that this claim is largely correct and that, consequently, any adequate theory of perception must explain the fact that perceptual experiences provide significantly less insight into the nature of secondary qualities than into the nature of primary qualities. I maintain that neither naïve realism nor the standard Russellian variety of the content (...) view can provide a satisfying explanation; instead, in order to provide a satisfying explanation, we must posit that perceptual experiences represent properties via Fregean modes of presentation. Further, I maintain that we must depart from the standard Fregean variety of the content view in two important respects. First, the relevant modes of presentation must be characterized without appealing to causal relations between perceptual experiences and perceived properties; and second, we must posit that primary and secondary qualities are represented via modes of presentation of different kinds. The resulting view is that primary qualities are represented via perceptual modes of presentation analogous to highly detailed descriptions, while secondary qualities are represented via perceptual modes of presentation analogous to impoverished descriptions.

The world contains objective causal relations and universals, both of which are intimately connected. If these claims are true, they must have far-reaching consequences, breathing new life into the theory of empirical knowledge and reinforcing epistemological realism. Without causes and universals, Professor Fales argues, realism is defeated, and idealism or scepticism wins. Fales begins with a detailed analysis of David Hume's argument that we have no direct experience of necessary connections between events, concluding that Hume was (...) mistaken on this fundamental point. Then, adopting the view of Armstrong and others that causation is grounded in a second-order relation between universals, he explores a range of topics for which the resulting analysis of causation has systematic implications. In particular, causal identity conditions for physical universals are proposed, which generate a new argument for Platonism. The nature of space and time is discussed, with arguments against backward causation and for the view that space and time can exist independently of matter or causal process. Many of Professor Fales's conclusions seem to run counter to received opinion among contemporary empiricists. Yet his method is classically empiricist in spirit, and a chief motive for these metaphysical explorations is epistemological. The final chapters investigate the perennial question of whether an empiricist, internalist and foundational epistemology can support scientific realism. (shrink)
