The paper examines Walter Chatton’s rejection of final causality. At the core of Chatton’s theory lies the claim that there are four kinds of cause, but only three kinds of causality, because final causality should in a sense be reduced to efficient causality. The author begins by situating Chatton’s theory in the context of the fourteenth-century discussions concerning the problematic status of ends as causes. After that, the paper reconstructs Chatton’s rejection of the opinio communis of his (...) time, according to which both final causes and final causality must be posited. The author claims that Chatton’s objections employ three main arguments, based on ontological parsimony, possible non-existence of ends, and the efficient character of love and desire. Then, Chatton’s own theory is presented. The author’s exposition is focused on Chatton’s thesis that final causes are said to be causes only in a metaphorical sense. The final part of the article examines William of Ockham’s reaction to Chatton’s theory. Arguing against Chatton’s teleology, Ockham wants to prove that we have good reasons to retain both final causes and final causality. (shrink)

This article focuses on one aspect of the late mediaeval debate over divine power, as it was discussed by Oxford philosophers Walter Chatton (d. 1343) and William Ockham (d. 1347). Chatton and Ockham would have agreed, for example, that God is ultimately responsible for the existence of the works of Pablo Picasso, but they would not agree over wheher it violates God's omnipotence to say that he cannot make something that Picasso made, for example, the painting Guernica, without (...) using Picasso himself as an intermediate cause. The context of their dispute was a larger debate regarding the ontological status of relations. This article (1) explains how these two issues, omnipotence and relations, became so interestingly tangled together, (2) tries to see which of the two men mentioned above got the better of their exchange, and finally (3) draws out some important consequences for fourteenth-century discussions of causality, occasionalism, and omnipotence.

William of Ockham (d. 1347) is well known for his commitment to parsimony and for his so-called ‘razor’ principle. But little is known about attempts among his own contemporaries to deflect his use of the razor. In this paper, I explore one such attempt. In particular, I consider a clever challenge that Ockham’s younger contemporary, Walter Chatton (d. 1343) deploys against the razor. The challenge involves a kind of dilemma for Ockham. Depending on how Ockham responds to (...) this dilemma, his razor will, Chatton argues, either prove unacceptably dull when it comes to determining ontological commitment or prove unacceptably sharp when it comes to determining commitments entailed by certain theological doctrines. While Chatton’s objection is subtle and interesting in its own right, the broader significance of the debate between these thinkers lies in the light it sheds on medieval approaches to issues surrounding metaphysical methodology.

Rondo Keele makes a foray into what he calls 'applied logic', investigating a complex argument strategy employed against Ockham by his greatest contemporary opponent, Walter Chatton. Chatton conceives a two-part strategy which attempts to force a kind of iteration of conceptual analysis, together with an infinite explanatory regress, in order to establish that one particular philosophical analysis is ultimately dependent on another. Chatton uses this strategy against Ockham in order to show that the latter's reductionist metaphysics depends ultimately upon (...) a deeper level of realist assumptions that he can neither evade nor explain away. Keele then shows how, earlier in his career, Chatton found himself on the receiving end of this same strategy, defending his own highly original solution to the problem of future contingents from the very iteration-regress attack he would subsequently use on Ockham. Keele concludes with an examination of Chatton's attempts to avoid the consequences of his own strategy, and draws some connections between this argument strategy and modal collapse in modern logics.

Thought experiments de facto play many different roles in biology: economical, ethical, technical and so forth. This paper, however, is interested in whether there are any distinctive features of biological TEs as such. The question may be settled in the affirmative because TEs in biology have a function that is intimately connected with the epistemological and methodological status of biology. Peculiar to TEs in biology is the fact that the reflexive, typically human concept of finality may be profitably employed to (...) discover mechanical-experimental causal relations in all living beings—with the obvious caveat that we do not hypostatise and interpret this concept as an ontological quality, since this would land one in an implicitly animistic, pre-Galilean view of nature. From a methodical point of view, the concept of finality is an essential assumption as well as a powerful heuristic tool in the practice of biology, that is, in the investigation of living beings in an intersubjectively testable and reproducible way.

Walter Chatton’s Reportatio has been dated to 1322-23, possibly at London, and his Lectura either as a revision of bachelor lectures given earlier at Oxford, or given after 1323. Stephen Brown has shown that material in Chatton’s Lectura dates to 1323-1324 when Chatton and Ockham were disputing in the same place, presumably London, before Ockham left England forever. The present article shows how arguments dating to one place and time can be used in a later work, and should not (...) be used to date that work. (shrink)

While many thirteenth-century scholastic philosophers thought that the human powers of sensation are distinct from the human intellect, this apparent consensus collapsed in the 1320s, ‘30s, and ‘40s. The proximate cause of this transformation was Walter Chatton’s rejection of William of Ockham’s arguments that the human powers of sensation are distinct from the human intellect. This article examines Chatton’s implicit and explicit motivations for rejecting Ockham’s arguments. I show that Ockham thinks that the senses are distinct from the (...) intellect because he holds that sensing is material and embodied in a way that thinking is not. I show that Chatton, on the other hand, sees no need to posit such a difference between sensation and thought with respect to materiality or embodiment because he thinks that nothing about the character of sensory experience shows it to be material or embodied in a way that thinking is not.

This book begins with standard ontological topics--such as the nature of existence--and of metaphysics generally, such as the status of universals, form, and accidents. What is the proper subject matter of metaphysical speculation? Are essence and existence really distinct in bodies? Does the body lose its unifying form at death? Can an accident of a substance exist in separation from that substance? Are universals real, and, if so, are they anything more than general concepts? Among the figures it examines (...) are Thomas Aquinas, John Duns Scotus, William of Ockham, Walter Chatton, John Buridan, Dietrich of Freiburg, Robert Holcot, Walter Burley, and the 11th-century Islamic philosopher Ibn-Sina. There is also an emphasis on metaphysics broadly conceived. Thus, additional discussions of connected topics in medieval logic, epistemology, and language provide a fuller account of the range of ideas included in the later medieval worldview. (shrink)

The present paper has a negative aim and a positive aim, both limited in the present context to a sketch or outline. The negative aim, today less controversial, is to show that Aristotle’s theory of final causality has little or nothing to do with the teleology rejected by modern science and that, therefore, far from having been rendered obsolete, it has yet to be fully understood. This aim will be met through the identification and brief discussion of some key (...) points on which Aristotle’s theory differs from teleology as still commonly understood. The positive aim is more controversial as it proposes that we take an ontology of life as the proper context for understanding the significance and nature of final causation in Aristotle. The argument for final causation, in other words, is that, without it, we would lose the phenomenon of life and, indeed, of nature altogether, reducing nature to the inanimate and mechanical.

Intellective intuitive cognition plays a key role in William of Ockham’s philosophy. On many occasions, Walter Chatton argues that this kind of cognition is unnecessary. Chatton has two main arguments for his point. First, he raises doubts about the possibility of distinguishing intellective intuitive cognition from sensory intuitive cognition. The former always arises with the latter, and whatever we can explain through the former, we can explain equally well through the latter. Second, he argues that we cannot separate (...) the intellective intuitive cognition of a singular thing from the cognition of the species of that thing. We cannot intuitively and intellectively cognize a thing without recognizing that thing as a thing of a certain kind. Chatton’s conclusion is that since we can never experience an act of intellective intuitive cognition in itself, it is superfluous to posit this act of cognition. We can explain the singular cognition of an extramental singular simply by making the cognition of its species and the sensory intuitive cognition of it interact with each other. (shrink)

My aim in this paper is to advance our understanding of medieval approaches to consciousness by focusing on a particular but, as it seems to me, representative medieval debate. The debate in question is between William Ockham and Walter Chatton over the existence of what these two thinkers refer to as “reflexive intellective intuitive cognition”. Although framed in the technical terminology of late-medieval cognitive psychology, the basic question at issue between them is this: Does the mind (or “intellect”) (...) cognize its own states via higher-order (or “reflexive”) representational states? Their debate is representative both because it highlights the central dialectical issues and alternatives at play in medieval discussions of consciousness generally and because it showcases the two main types of approach to consciousness one finds in the later medieval period, namely, those that explain consciousness in terms of intentionality (typically, higher-order intentionality), and those that understand consciousness as a non-intentional, sui-generis mode of awareness.

This article presents a novel argument against a common principle of parsimony in philosophy. First, it identifies a widely employed principle of positive ontological parsimony, according to which we should, ceteris paribus, prefer smaller ontologies to larger ontologies. Next, it shows how this principle is used as part of a strategy by which to argue for antirealist positions in many subfields of philosophy: the ockhamistic antirealist strategy. Third, it argues that this principle commits its adherents to an (...) implausible epistemological thesis—the Eroding Ontology Thesis—according to which evidence for the existence of some entity is at least prima facie evidence against the existence of all other entities. Antirealists might decide to adopt a related position, ontological conservatism, according to which we should simply resist changing our ontology, but the article shows that it is independently unjustified. Therefore, it concludes, philosophers have good reason to cease employing one very common antirealist strategy. (shrink)

In Walter Chatton on Future Contingents, Jon Bornholdt presents the first full-length translation, commentary, and analysis of the various attempts by Chatton (14th century C.E.) to solve the ancient problem of the status and significance of statements about the future. At issue is the danger of so-called logical determinism: if it is true now that a human will perform a given action tomorrow, is that human truly free to perform or refrain from performing that action? Bornholdt shows that Chatton (...) constructed an original (though problematic) formal analysis that enabled him to canvass various approaches to the problem at different stages of his career, at all times showing an unusual sensitivity to the tension between formalist and metaphysical types of solution.

An appeal to ontological parsimony or economy plays an important, perhaps indispensable, role in evaluating metaphysical theories. This chapter focuses primarily on the first conception of grounding, grounding as metaphysical explanation. It briefly discusses the relation of ontological dependency and its connections with grounding as explanation. Debates about grounding are a recurring theme in the history of Western philosophy. Much of Aristotle's metaphysical method also presupposes the existence of a grounding relation. The chapter investigates both conceptual and (...) ontological grounding and explores the relationship between grounding and truthmaking. The chapter considers various alternatives or competitors to grounding theory. It examines the connection between grounding, fundamentally, and Ockham's Razor and also relation between grounding and ontological dependence. The chapter shows how grounding is different from causal explanation and discusses connections between grounding and entailment. (shrink)

Many metaphysicians often appeal to Hume’s dictum (HD), according to which there are no necessary connections between distinct entities (or states of entities), in order to resist theories that commit us to such connections. Some have argued that HD is an unsupported dogma of metaphysics. But theories that commit us to necessary connections between distinct goings-on can also be resisted by invoking a normative twist on HD, which I call the Humean Solvent (HS): “Do not connect distinct entities (or states (...) of entities) beyond necessity”. HS is a principle of structural parsimony – assuming that a theory is structurally more parsimonious than another when the latter is committed to a more connected ontology than the former is. Just as Ockham’s ‘razor’ encourages us to cut down superfluous ontological commitments, the Humean ‘solvent’ encourages us to dissolve dispensable metaphysical glue: we ought not to glue elements of our ontology beyond necessity. HS has both a qualitative and a quantitative dimension: qualitatively, it encourages us to avoid using metaphysical glues that are unnecessarily strong, the strongest of which being metaphysically necessary connections; quantitatively, it encourages us not to metaphysically glue things that need no gluing. Thus, given HS, other things being equal, what is worst is a theory that entails that everything is metaphysically necessarily connected to anything else and what is best is a theory that leaves all things loose and separable. In this paper, I will first compare HD and HS as grounds for paradigmatic Humean doctrines in contemporary metaphysics, then I will argue that structural parsimony is neither a variety of ontological nor of ideological parsimony; finally, I will offer an argument for HS.

I assess various proposals for the source of the intuition that there is something problematic about contextuality, ultimately concluding that contextuality is best thought of in terms of fine-tuning. I then argue that as with other fine-tuning problems in quantum mechanics, this behaviour can be understood as a manifestation of teleological features of physics. Finally I discuss several formal mathematical frameworks that have been used to analyse contextuality and consider how their results should be interpreted by scientific realists. In the (...) course of this discussion I obtain several new mathematical results—I demonstrate that preparation contextuality is a form of fine-tuning, I show that measurement contextuality can be explained by appeal to a global constraint forbidding closed causal loops, and I demonstrate how negative probabilities can arise from a classical ontological model together with an epistemic restriction.

This light revision of Bornholdt's doctoral thesis (Würzburg, 2015) is effectively a medievally-oriented follow-up to Richard Gaskin’s 'The Sea Battle and the Master Argument' (1995). The book is stimulating from a philosophical point of view, but the exegesis is disappointingly unreliable.

The so-called bottoming-out problem is considered one of the most serious problems in Stuart Glennan's mechanistic theory of causality. It is usually argued that such a problem cannot be overcome with the acknowledgement of the non-causal character of fundamental phenomena. According to such a widespread view, in the mechanistic account causation must go all the way down to the bottom level; a solution to the bottoming-out problem, therefore, requires an appeal to an ancillary account of causation that covers fundamental phenomena. (...) In this paper I reconsider the arguments that led to this conclusion and criticize them. I argue that the no-causality-at-the-fundamental-level solution is in harmony with the causal anti-fundamentalism that characterizes the mechanistic theory. Moreover, contrarily to the dualistic solution put forward by Glennan, the no-causality-at-the-fundamental-level is not an ad-hoc solution.Finally, I provide the sketch for an account of the existence of an order in nature at the fundamental level that is consistent with the singularist and ontologically parsimonious spirit of the mechanistic account.

_ Source: _Page Count 24 Although the fourteenth-century Franciscan theologian Walter Chatton did not comment on Aristotle’s _Categories_, he discussed a number of issues relating to categories in his _Lectura_ on the _Sentences_. The author examines his response to the question ‘How many categories are there?’ He gives three methods by which we can arrive at the number of the categories, the last two of which seem to meet his approval. Chatton advocates a strong isomorphism between ontology and semantics: (...) the number of the categories is determined by and equal to the number of classes of things. (shrink)

Ockham developed two theories to explain the intentionality of memory: one theory that takes previously perceived things to be the objects of memory, and another that takes one’s own earlier acts of perceiving to be the objects of memory. This paper examines both theories, paying particular attention to the reasons that motivated Ockham to give up the first theory in favor of the second. It argues that the second theory is to be understood as a theory of double intentionality. At (...) the core of this theory is the thesis that one directly remembers one’s own acts, and indirectly also the objects of these acts. The paper analyzes the cognitive mechanism that makes this double intentionality possible and examines the causal account that Ockham gave for explaining the emergence of acts of remembering. It emphasizes that he accepted nothing more than a causal chain of acts and habits, thereby offering an ontologically parsimonious theory of memory. (shrink)

Powers ontologies are currently enjoying a resurgence. This would be dispiriting news for the moderns; in their eyes, to imbue bodies with powers is to slide back into the scholastic slime from which they helped philosophy crawl. I focus on Descartes’s ‘little souls’ argument, which points to a genuine and, I think persisting, defect in powers theories. The problem is that an Aristotelian power is intrinsic to whatever has it. Once this move is accepted, it becomes very hard to see (...) how humble matter could have such a thing. It is as if each empowered object were possessed of a little soul that directs it and governs its behavior. Instead of attempting to resurrect the Aristotelian power theory, contemporary philosophers would be best served by taking their inspiration from its early modern replacement, devised by John Locke and Robert Boyle. On this view, powers are internal relations, not monadic properties intrinsic to their bearers. This move at once drains away the mysterious directedness of Aristotelian powers and solves the contemporary version of the little souls argument, Neil Williams’s ‘problem of fit.’. (shrink)

In this essay, we reconsider two themes particularly discussed by the interpreters of Ockham: that of divine omnipotence and the hypothesis of the intuitive cognition of non-existent things. The purpose is to show that the hypothetical case considered by Ockham was subjected to opposite interpretations. For theological reasons, Ockham attributes not only to God but also to human beings the possibility of having acts of intuitive cognition of things that do not exist; nonetheless, he holds that it is contradictory for (...) God to give us the evident cognition of things that appear to be present when they are actually absent. Walter Chatton opposes this conclusion, arguing that no contradiction ensues from that hypothesis. Instead, he believes that it is impossible for God to give us the intuition of things that absolutely do not exist or are in no way present to us. Ockham’s arguments include some difficulties that Chatton acutely sees and discusses. In particular, Chatton calls into question Ockham’s missed distinction between the existence and the presence of the intuited thing. (shrink)

In this paper, I argue that Nietzsche’s published works contain a substantial, although implicit, argument for the will to power as ontology—a critical and descriptive, rather than positive and explanatory, theory of reality. Further, I suggest this ontology is entirely consistent with a naturalist methodology. The will to power ontology follows directly from Nietzsche’s naturalist rejection of three metaphysical presuppositions: substance, efficient causality, and final causality. I show that a number of interpretations, including those of Clark, Schacht, Reginster, and (...) Richardson, are inconsistent with Nietzsche’s naturalism, because they presuppose efficient or final causality. In contrast, I argue that the will to power is not an explanatory theory, but a description of the basic, necessary character of reality, designed to critically reveal and minimize metaphysical presuppositions—to reject false explanations of reality and human behavior. It avoids substance-metaphysics by describing reality as will, a causal process without discrete efficient causes or agents. It eliminates efficient causality by describing events as maximal manifestations of power, rather than as agent-actualized potentialities. Finally, it opposes teleology by describing life as tending toward the activity of resistance as such, rather than toward explanatory end-states, such as the accumulation of power or overcoming of resistances.

In lieu of an abstract, here is a brief excerpt of the content:Reviewed by:Wilfrid Sellars and Phenomenology: Intersections, Encounters, Oppositions ed. by Daniele De Santis and Danilo MancaHeath WilliamsDE SANTIS, Daniele and Danilo Manca, editors. Wilfrid Sellars and Phenomenology: Intersections, Encounters, Oppositions. Athens: Ohio University Press, 2023. xiv + 272 pp. Cloth, $95.00This is an eminently readable and engaging collection of essays. There is much more here than merely comparing and contrasting two disparate thinkers. There are important contributions to metaphysics, (...) epistemology, thought about the relation between science and culture, and the future of phenomenology and pragmatism. It has what one wants from a collection of edited papers: very few contributions that are obscure or tangential, with nearly every one addressing a broadly relevant philosophical topic.The two major motifs running through the various works in this edited book are epistemologically orientated questions on the myth of the given, and metaphysically orientated questions arising from the contrasting scientific and manifest images. As Landfredi states, these "are two main theoretical dimensions in which phenomenology and Sellars's approach critically confront each other."To the metaphysical motifs firstly. Husserl's thoughts on the relation between the scientific and manifest image is outlined in his Crisis of the European Sciences and Sellars's in Philosophy and the Scientific Image of Man. In contemporary metaphysics, the competition between the manifest and scientific image has been heightened thanks to the aggressive scientific realism of works like Ladyman and Ross's Everything Must Go, coupled as it is with a dismissal of our commonsense perceptual and cognitive capacities.Both Lanfredi and Manca take a conciliatory approach, aiming to minimize incompatibility between Husserl's manifest and Sellars's scientific images. Manca's attentive and judicious reading makes apparent the origins of the metaphysical commitments of both thinkers. The former accepts the power of the scientific method of mathematization but warns that its ontology remains forever incomplete until the lifeworld is considered. The latter's scientific realism ultimately affords science the final say on what exists. The difference between them comes down to whether the emergent properties of a system are ultimately reducible to parts and the arrangement between them. Sellars thinks they are, while for Husserl "the parts are not juxtaposed from without but integrated with each other in such a way that they become able to generate new [End Page 546] properties." A thematically related analysis is found in the contribution of De Santis, who argues that Simons's adaptation of Husserlian mereology fails to provide a solution on how to build complex particulars out of basic ones.Hopp's article connects our two domains of critical encounter as he suggests that you can get from a phenomenological epistemology to a metaphysical reification of items in manifest image, because fulfilled perceptual knowledge claims presuppose the existence of that which is perceived. He thinks there are resources within Husserl not only to defend this position but to use it to critique many of the claims that undergird Sellars's prosecution of the myth. Hopp ends by asking what current experimental evidence the scientific realist has to rule out the existence of macrosized phenomenologically given objects. One might refer to the above-mentioned work by Ladyman and Ross by way of reply.Epistemological themes include the claim that aspects of phenomenology can be imported or modified to forge a coherent account of perceptual knowledge that (a) affords perception a role in epistemology and (b) explains the concomitant, vexing relation between the space of reasons of causes while (c) avoiding the myth of the given.Two authors who demonstrate close parallel between Husserl and Sellars are Nunziante and Rump. Nunziante shows that one of Sellars's attempts at (a) comes via his account of "perceptual takings," which is influenced by, and homologous to, Husserl's account of the passive synthesis of prepredicative perception in Experience and Judgement, as handed to Sellars by Farber. These prove to be essential stepping stones in Sellars's thinking about how the perceptual realm marries to the intellectual one.Rump shows that Sellars's attempt to solve the regress problem for coherentism in order to solve (a) stumbles on the problem of how causal, nonconceptual, noncategorial, and nonpropositionally structured protoperceptual experiences furnish...

This paper traces a rather peculiar debate between William Ockham, Walter Chatton, and Robert Holcot over whether it is possible for God to know more than he knows. Although the debate specifically addresses a theological question about divine knowledge, the central issue at stake in it is a purely philosophical question about the nature and ontological status of propositions. The theories of propositions that emerge from the discussion appear deeply puzzling, however. My aim in this paper is (...) to show that there is a way of making sense of these views (and, by implication, of much of what is puzzling about medieval theories of propositions). The key, I argue, lies in getting clear about the precise theoretical roles these thinkers assign to propositions in their accounts of propositional attitudes. (shrink)

The article focuses on one important aspect of this debate between Realists and Nominalists in the Late Middle Ages, namely the controversy between William Ockham and Walter Burley about the nature and status of relations and relatives, for the category of ad aliquid is the most intriguing category after substance, and in Late Antiquity and the Middle Ages many authors attempted to develop new formulations of the Aristotelian theory of relatives. Burley believed that when two substances are related (...) one to the other, five distinct elements can be singled out: the relation itself (for instance, the form of paternity); the ultimate substrate of that relation (namely, the substance that denominatively receives the name of the relation - the animal which is called ‘father’ because it begot another similar to itself); the fundamentum of the relation (namely the categorial item in virtue of which the relation inheres in its substrate - in our example, the generative power); the antecedent term of the relation (namely the aggregate formed by the substrate in which the relation inheres and the relation itself - in our example, the father); and the consequent term of the relation (namely, the aggregate formed by the substance with which the subiectum is somehow connected and the relation correlated to the first one - in our example, the son). In fact, according to Burley, any relation has its own converse. The foundation is the main component, since it joins the relation to the underlying substances, permits the relation to link the antecedent term to the consequent term, and transmits some of its properties to the relation. Ockham, on the contrary, believed that terms such as ‘relativum’, ‘relatio’, and ‘ad aliquid’ are terms of second intention, since they signify other (vocal, written, mental) terms, when taken in personal supposition. In Ockham’s opinion, Socrates qua father cannot be regarded as a relative; it is the name ‘father’ (and the corresponding intentio) that is a relative. This implies that the abstract terms of the category, namely those terms that in Burley’s view signify relations such as ‘paternitas’, and the concrete terms, namely those terms that in Burley’s view signify relatives such as ‘pater’, are synonymous according to Ockham. He thinks that any abstract term belonging to the category of ad aliquid is semantically equivalent to the definition (in a broad sense) of the correlated concrete term, so that, for instance, ‘paternity’ in a sentence like ‘a father is a father because of paternity’means: a father is a father because he has begotten a son. Such differences between them in their divergent interpretations of Aristotle’s theory of ad aliquid consist in the opposing roles that reality plays in their explanations of human knowledge, and Ockham’s rejection, in favour of a principle of ontological parsimony, of the principle of a close isomorphism between (mental) language and the world. For Burley, extra-mental reality was the model that our knowledge has to adequate and reproduce, whilst Ockham conceived of reality as a simple object of our knowledge, which does concern reality, but is articulated according to inner principles. Burley’s thought was dominated by the object-label scheme, as the basic semantic relation, and by hypostatization, regarded as the practice of replacing logical and epistemological rules by ontological standards and references, as the main device for explaining the semantic function of language. On the contrary, for Ockham reality must consist of as few as possible kinds of being. (shrink)

Ockham’s Razor advises us to not multiply entities without necessity. Recently, Jonathan Schaffer and Karen Bennett have argued that we ought to replace Ockham’s Razor with the Laser, the principle that only advises us to not multiply fundamental entities without necessity. In this paper, I argue that Ockham’s Razor is preferable to the Laser. I begin by contending that the arguments offered for the Laser by Schaffer and Bennett are unpersuasive. Then I offer two cases of theory assessment that I (...) believe the Razor handles better than the Laser. Finally, I argue that accepting the Laser gives rise to a difficult explanatory challenge: It is difficult to explain why fundamental entities and non-fundamental entities ought to be treated differently in ontological parsimony assessments. A recurring secondary theme of the paper is that the most tempting ways of responding to my arguments frequently result in the Laser losing much of its significance for debates about ontology. Thus, not only is it difficult to defend a preference for the Laser over the Razor, but it is especially difficult to do so while maintaining the Laser’s dialectical significance. (shrink)

Polanyi’s vision of the cosmic process as undergirded by a logic of emergence common to both the mental life of human beings and the processes of non-human nature can be vindicated if one is prepared to make certain adjustments in the notion of morphogenetic fields with an active center or organizing principle. Given the author’s field-oriented interpretation of Whiteheadian societies, it should be possible to think of entelechies or final causes in developmental rather than strictly Aristotelian terms. That is, (...) the “common element of form” or organizing principle of a Whiteheadian society depends for its own existence on the spontaneous activity of previous sets of actual occasions and yet serves as the ongoing principle of formal and final causality for the present set of actual occasions and still others to follow it. In Aristotelian language, matter and form thus dialectically condition one another and neither is ontologically superior to the other. (shrink)

In this paper, I intend to present the way in which contingency and causal determinism relate in some major late-medieval views on the metaphysics of causation. I will focus on Thomas Aquinas, John Duns Scotus, William of Ockham, and John Buridan. First, I will show that Scotus’s new insights into the metaphysics of modalities had important consequences for the way contingency was related to causality: Ockham and Buridan do not consider contingency as a by-product of the necessary emanation of (...) God any more but as a distinctive property of God as the first cause and, therefore, of the created world as a whole. Second, I will show that the growing interest from Scotus onward in explaining and justifying inductive reasoning led to an extensive analysis of the nature and function of the principle of the uniformity of nature. Third, I will explain why the progressive psychologization of final causes led to the exclusion of final explanations from physics. The consequence of this process is the development a new way of conceiving chance and hazard, and the separation between free and natural agents. We can speak here of a tendentially mechanistic picture of the world. (shrink)

Numerous writers have recently called for reform in psychological theorizing and research methodology designed to appreciate the teleological, active agent capacities of humans. This paper presents three studies that probe individual's abilities to volitionally control their eating behavior. These investigations suggest one way that researchers might consider the operation of telic powers in human action. Rather than seeing teleological explanations as rivals to the more traditional causal explanations favored in psychological research, this paper elaborates a position that sees human volition (...) as a causal force embedded in the traditional causal influences studied in psychological research. Finally, the theoretical and methodological refinements suggested here and elsewhere are seen against the backdrop of a philosophy of science that sees change as a more gradual, evolutionary process, rather than the Kuhnian, revolutionary process.

Medieval scholastics share a commitment to a substance-accident ontology and to an analysis of efficient causation in which agents act in virtue of their powers. Given these commitments, it seems ready-made which entities are the agents or powers: substances are agents and their accidents powers. William of Ockham, however, offers a rather different analysis concerning material substances and their essential powers, which this article explores. The article first examines Ockham’s account of propria and his reasons for claiming that a (...) material substance is essentially powerful sine accidentibus. However, the article subsequently argues that, given Ockham’s reductionism about material substance, only substantial forms – never substances – are truly agents and powers. Thus, a material substance is essentially powerful but only by courtesy – per accidens, as Ockham calls it – because it has a non-identical part, its substantial form, which does all the causal work by itself, per se.

Against the background of the current discussion about self-organization theories and complexity theories and their application within biology and ecology, the question of teleology gains a new significance. Some scholars insist on the total elimination of any reference to teleology from the realm of the natural sciences. However, it seems especially hard to eradicate teleological expressions from scientific language when the issue of understanding living beings is at stake. For this reason, other scholars opt for a middle path that allows (...) for some teleological language. Yet, it is an open question whether teleological expressions are to be considered as playing a merely metaphorical or a necessary heuristic role in the sciences. Moreover, the ontological presuppositions, which underpin different positions in the debate, need to be depicted and analyzed. This paper aims at addressing the question of teleology within the life sciences by taking into account both Kant’s critical philosophy and Whitehead’s ontology. My analysis starts with Georg Toepfer’s distinction among different concepts of teleology and then focuses on the role of “internal purposiveness” (innere Zweckmäßigkeit) for biology today. I show how purposiveness (Zweckmäßigkeit; hereafter: ZM) corresponds to a very complex form of reciprocal causation (Wechselwirkung) rather than to any model of final causation. Drawing on Kant’s analysis of “natural purposes” in the Critique of Judgment as well as selforganization theory, I claim that reciprocal causation – however complex it might well be – is not sufficient to describe living beings adequately. However, since the natural sciences are still caught up in the presuppositions of modern scientistic and materialistic ontology, a step beyond mere efficient causation seems to be impossible within their methodological framework. And yet, as I will show, a genuine teleology of nature implies the idea of anticipation of totality. This kind of teleological consideration is presented at first in its role as a regulative concept in Kantian terms. Finally, I follow the path of Whitehead’s ‘philosophy of organism’ and claim for natural teleology the state of a necessary ontological presupposition. Whitehead’s ontology offers an ontological underpinning for teleological issues that, by avoiding any recourse to supernatural forces, invites life and natural sciences to a fruitful dialogue at the limit of their methodological boundaries, pressing them beyond their unreflected presuppositions.

In this paper, I propose a framework that supports both free will and anomalous mind-matter interaction (psychokinesis). I begin by considering the argument by the physicist Sean Carroll that the laws of physics as we understand them rule out psychokinesis (and other modes of psi). I find Carroll’s claims problematic, in part due to what I believe are misunderstandings of arguments borrowed from David Hume. I proceed to consider a more dispositional notion of causality (in contrast to one characterized by (...) universal and necessary laws) which I argue is more hospitable to both psychokinesis and free will. I then incorporate recent work from the philosophy of mind and science to arrive at a framework that supports both real volition and psychokinesis, which I argue are intimately linked. This approach is fundamentally dispositional, but grounded in an ontologically prior field of awareness and potentiality. I also consider that the regularities (or causal natures) we observe in our physical world are ultimately supported by what we might term teleological “intentions” within a nonlocal, mind-like quantum ground.

This paper is dedicated to William of Ockham’s theory of habit, which he considers to be a disposition of a power of the soul. I will argue that Ockham’s view on the relation between a habit and its manifestation sheds new light on his well-known thesis that sensible and intelligible species are not needed to account for cognition. The identity conditions of habits are themselves the ground of their intentionality: there is no way to track a habit from an (...) act of a given kind except by stipulating a causal relation between them. In this sense, a study of Ockham’s theory of habit is a step towards our understanding of the relation between similarity and causation in his theory of intentionality. Ockham’s theory of habit accommodates intentional phenomena that, contrary to the scholarly consensus, are not ipso facto semantic phenomena. (shrink)

It is well-known that Chatton is among the earliest and most vehement critics of Ockham’s theory of judgment, but scholars have overlooked the role Chatton’s criticisms play in shaping Ockham’s final account. In this paper, I demonstrate that Ockham’s most mature treatment of judgment not only contains revisions that resolve the problems Chatton identifies in his earlier theories, but also that these revisions ultimately bring his final account of the objects of judgment surprisingly close to Chatton’s own. Even (...) so, I argue that, at the end of the day, there remain significant differences between their respective analyses of the structure and intentionality of judicative states. (shrink)

Functional contexts have long been recognized to support evaluative judgments of a certain kind, even where there is no element of design: we speak, for example, of such things as good roots or defective hearts in connection with judgments about proper functions; an animal might even be judged defective for failing to possess a certain species-typical, functional behavioral disposition. These are obviously not moral judgments, but it is interesting to wonder whether the latter might be understood in a similar way. (...) Can moral virtues, for example, be understood as dispositions to function properly in certain spheres of human life involving the will, so that someone lacking them might be said to have a defective character? ;One possibly tempting way of pursuing this broadly Aristotelian line, which has been proposed in recent work by Philippa Foot, would be to argue that there is a single type of functional framework within which to understand both function-related evaluations in biology generally, and function-related evaluations pertaining to ethics and practical rationality; in both cases, it might be thought, talk of species-typical functions and proper functioning is to be understood in relation to the flourishing of the organisms in question, the difference being that the functions relevant to ethics would involve the will. ;I argue that this way of fleshing out a neo-Aristotelian approach to ethics and practical rationality is misguided. Much of the dissertation is devoted to showing this by developing a positive account of functional teleology in biology which makes clear that the flourishing or welfare-promotion of organisms is neither a general nor an ultimate end within the biological functional framework. The view I defend recognizes the crucial role played by natural selection history in shaping facts about present functional teleology, but it is importantly different from what are generally known as "etiological" views. In particular, it does not involve any direct reduction of facts about function to facts about causal history, and it suggests a non-reductionist view of functional teleological explanation, which I also defend. The rejection of etiological views of function in general leaves open the possibility that there is some kind of functional framework, distinct from the biological one, that might be relevant to ethics; I explore this in the last chapter.

Two of the best currently practising scholars of Ockham, Marilyn Adams and Paul Spade, seem to have accepted a reading of Ockham's ontological program which, although it contains much that is uncontroversially correct, attributes to Ockham a reductionist view that is on my interpretation of his works far too radical to be genuinely Ockham's. Their reading runs as follows. So far as entities go, Ockham accepts only particular substances and some particular qualities. Aristotle's categories, according to Ockham, are not (...) 10 broad classes of radically different sorts of things, but rather are classes of non-complex terms arranged roughly according to the kinds of questions they can be used to answer. When we look at these terms we find that those in the category of substance and some in the category of quality are not definable by some longer expression synonymous with them but simply signify each of the members of a certain class of substances or qualities. These terms are said to be absolute. But other terms can either be replaced by a definition that is synonymous with the term defined or can be interpreted as making “exponible” the sentences in which they occur. These terms are all said to be connotative. It is in principle possible to reword all the sentences in which these connotative terms appear so that the only categorematic terms left are absolute terms from the categories of substance and quality.

Avicenna's theory of final causality stands out as one of the most profound and original achievements of Islamic philosophy. Writing mainly in Arabic in various cities of Persia from the end of the 4th/10th to the beginning of the 5th/11th centuries AH/AD, Avicenna extended the range of Aristotelian teleology to encompass not only motion but also existence; he did so by dividing the final cause into an extrinsic, kinetic end , and an intrinsic, static perfection . ;My dissertation (...) is organized to test Avicenna's hypothesis that the final cause thus extended was applicable to every subject of every science. I begin by examining how the final cause behaves in the relations between logical entities--terms, premises, definitions, quiddities--and then argue that Avicenna saw the final cause as a bridge between that world of logical entities and the sensible world, whose own relations logic is supposed to systematize. I go on to explain how Avicenna used the twin aspects of Aristotle's notion of nature--one an extrinsic agent keeping the world of natural things in order, the other an intrinsic form serving as the natural thing's source of motion--as a basis for his division of final causes into ends and perfections; I also examine how this division helped Avicenna attempt a reconciliation of chance and natural necessity. I then assess how Avicenna's medical experience--specifically his close observation of the complex teleological processes that cause an organism to exist and function--provided empirical support for his distinction between ends and perfections. Finally I argue that Avicenna viewed the relation between final and efficient causes as one of reciprocal necessitation, based on the premise that each was both cause and effect of the other; here Aristotle's notions of limit and actuality provide some of the metaphysical background to Avicenna's teleology. ;Previous studies of Avicenna's theory of causality have focused almost entirely on the efficient cause; my intention here is to prove that an understanding of Avicenna's teleology should be a prerequisite to any future such study.

The range of this volume, and thus the task especially of its editor, is enormous: to confront the question of teleology from Plato through Aristotle, Maimonides, Aquinas’s commentaries on the Physics, Copernicus, Machiavelli, Bacon, Galileo, Descartes, Spinoza, and Newton, to Kant, Hegel, and then to Einstein, and to recent theories of anthropic-principle cosmology or else versions of the many-worlds cosmology of chance and necessity, and then to Niels Bohr and quantum mechanics, and finally to the problem of current molecular-biological theories (...) of evolution.

The great philosopher and historian of philosophy, Etienne Gilson, sets out to show that final causality or purposiveness and formal causality are principles for those who think hard and carefully about the world, including the world of biology. Gilson insists that a completely rational understanding of organisms and biological systems requires the philosophical notion of teleology, the idea that certain kinds of things exist and have ends or purposes the fulfillment of which are linked to their natures-in other words, (...) formal and final causes. His approach relies on philosophical reflection on the facts of science, not upon theology or an appeal to religious authorities such as the Church or the Bible. (shrink)

Walter Chatton (ca. 1290–1343) is not exactly a household name—even among historians of medieval philosophy. Indeed, to the extent that he is known to scholars, it is more for his role as a critic of William of Ockham (d. 1347) than for any particular philosophical contribution of his own. Part of the reason for this owes to Chatton's own philosophical style: he uses his objections to Ockham's (and, to a lesser extent, to Peter Aureol's) views as a foil (...) for developing his own. Another, larger part of the explanation, however, is that the bulk of Chatton's philosophical writings have not been accessible for research and study. Thanks to the efforts of the late Joseph Wey and Girard Etzkorn, this is no longer the .. (shrink)

Part I argues that ontological arguments, like other classical proofs of the existence of God, are parts of larger arguments in which they are embedded. These larger arguments include reasons supporting the proofs’ premises and responses to them, and to the proofs’ claims to validity and non-circularity, since, in the final analysis, our assessment of the proofs will express our best judgment of the cumulative force of all the considerations bearing on their overall adequacy. Part II illustrates these (...) points by examining contemporary defences of, and attacks on, one of the ontological argument’s central premises, namely, that God’s existence is logically possible.

Existentialist Ontology and Human Consciousness The majority of the distinguished scholarly articles in this volume focus on Sartre's early philosophical work, which dealt first with imagination and the emotions, then with the critique of Husserl's notion of a transcendental ego, and finally with systematic ontology presented in his best-known book, Being and Nothingness. In addition, since his preoccupation with ontological questions and especially with the meanings of ego, self, and consciousness endured throughout his career, other essays discuss these themes (...) in light of later developments both in Sartre's own thought and in the phenomenological, hermeneutic, and analytic traditions.

One of the world's great philosophers, William of Ockham's On the Connection of the Virtues (De connexione virtutum) provides insightful perspectives on ordinary issues of human conduct. Written in reasonably simple and nontechnical language, it is translated into English here for the first time. Ockham's views on many subjects have been misunderstood, his views on ethics as much as any. This book is designed to avoid some pitfalls that arise in reading medieval philosophy generally and Ockham in particular. Wood (...) begins her introduction with an account of what is known about Ockham's life and works and with a discussion of his place in the history of philosophy, followed by a brief general guide to his views. Finally, there is a historical account of the medieval debate on the connection of the virtues, to which Ockham's treatise is an important contribution. Problems of interpretation are addressed in the commentary, which follows the translation. Translation, commentary, and introduction provide students of Ockham's treatise with what they need to appreciate his stance on ethical issues and to approach his arguments critically. (shrink)

This massive study makes an important contribution to the history of philosophy for two reasons. First of all, it stands as the most complete and careful philosophical analysis of Ockham's thought to date. Adams's expositions and analyses will become the gloss which generations of students will have to reckon with as they confront the text of Ockham. Secondly, this work represents an exemplary method of philosophical commentary, one that proves to be a remarkably illuminating way into the mind of a (...) medieval scholastic disputant. Because Ockham's thought is intensely dialectical and argumentative, Adams appropriately exposes his doctrines through an exacting recovery of his argument within its dialogical context. For example, in the crucial chapter 2, "Universals Are Not Things other than Names," we come to understand Ockham's nominalism as it emerges from his rejection of moderate realism; Adams presents this rejection through a reconstruction of Ockham's encounter with the living tradition of Aquinas, Scotus, Walter Burleigh, William of Alnwick, Nervaeus Natalis, and Henry of Harclay. As the dialectic proceeds from figure to figure, the issue of the universal reshapes itself with great sophistication. Adams's formidable analytic powers and her sharp focus on the key philosophical issue enable her to succeed in this method. The reader also gets the sense that Adams herself believes one can come to truth through philosophical argument, and not just the truth of what Ockham taught but the truth of what he sought. This earnestness enables her to keep a fix on the dialectic's "emerging rule" which becomes the source of unity in what could otherwise degenerate into a bewildering complexity of historical detail or the vanity of analytic logic-chopping.

Professor de Rijk's interest here is in the views on reality put forward by the medieval thinkers from Boethius to William of Ockham, but especially in the 12th-14th centuries, the period from Abelard onwards.Theology was naturally a key influence, but sematic theories - the philosophical theories on how terms signify, or how a name has its meaning and how this is affected by its context - were fundamental as the starting point of ontological speculation. The categories formulated in (...) order to differentiate various types of context and their impact on the semantics of the verb esse, 'to be', and its related forms. De Rijk's aim is to understand how these medieval thinkers interpreted reality according to their own semantic views, and to see how their own particular concerns - for instance William of Ockham's application of the 'principle of parsimony' to ontology - shaped the nature of their thought.

Many who write on race consider it an ‘illusion’. Others argue that race is real, even if socially constructed, because the notion of race, and the categorizing of people in terms of race, has greatly affected their lives. This paper criticizes a reason that is often given for thinking that race is an illusion: the fact that there is no biological basis of race. I defend two primary claims. First, while there is no biological basis for membership in a socio-economic (...) class, by which I mean one's being relatively affluent or poor in a particular society, no one takes socio-economic class to be an illusion. Second, race is arguably a more fundamental reality than is socio-economic class. For one's racial identity can causally contribute to, and account at least partly for, one's membership in a socio-economic class. But membership in a socio-economic class does not thus contribute to, or account for, people's racial identities. (shrink)
