This paper explores the consequences of the theoretical forward activation enzymatic pathway A 0 A 1 A 2 A 3 where E 1 convents A 0 to A 1, E 2 converts A 1 to A 2 and E 3 converts A 2 to A 3. A 0, which is environmentally determined, also serves to activate (or modulate) the activity of E 3 in such a way as to keep the concentration of A 2 ([A 2]) constant at a particular (...) set-point value. For mathematical simplicity, first order rate kinetics are used where k 1, k 2 and k 3 are the rate constants for E 1, E 2, and E 3 respectively. It is shown that if k 3 is modulated appropriately so as keep [A 2] at the setpoint value with a changing upstream [A 0], then the modulation of k 3 must be anticipatory of the dynamics of the biochemical pathway. In other words, the rate of change of k 3, will be a function of [A 0], k 1, k 2, k 3, and the set-point value of [A 2]. If the modulation of k 3 does not perfectly model (anticipate) the reaction pathway of which it is a part, then the actual [A 2] will deviate from the set-point value. This type of anticipatory feed-forward activation may represent an important aspect of biological organization. (shrink)

According to our traditional conception of agency, most human beings are agents and most, if not all, nonhuman animals are not. However, recent developments in philosophy and psychology have made it clear that we need more than one conception of agency, since human and nonhuman animals are capable of thinking and acting in more than one kind of way. In this paper, I make a distinction between perceptual and propositional agency, and I argue that many nonhuman animals are perceptual agents (...) and that many human beings are both kinds of agent. I then argue that, insofar as human and nonhuman animals exercise the same kind of agency, they have the same kind of moral status, and I explore some of the moral implications of this idea.

According to liberal egalitarian morality, all human beings are one another's moral equals. Nonhuman animals, by contrast, are not considered to be our moral equals. This essay considers two challenges to the liberal egalitarian view. One is the ``separation problem,'' which is the challenge to identify a morally significant intrinsic difference between all human beings and all nonhuman animals. The other is the “equality problem,” which is to explain how all human beings can be morally equal when there are some (...) human beings whose psychological capacities are no higher than those of certain nonhuman animals. The focus throughout is on the ethics of killing but the arguments are of broader relevance. The essay reaches a skeptical conclusion about our ability to meet these challenges. (shrink)

Demonstratives have different semantic values relative to different contexts of utterance. But it is surprisingly difficult to describe the function from contexts to contents which determines the semantic value of a given use of a demonstrative. It is very natural to think that the intentions of the speaker should play a significant role here. The aim of this paper is to discuss a pair of problems that arise for views which give intentions this central role in explaining the characters of (...) demonstratives. As will emerge, these problems lead quickly to a foundational question about the semantics of demonstratives and many other context-sensitive expressions: the question of whether, in explaining their characters, we need to understand them as sensitive, not just to facts about the psychology of the speaker of the context, but also to facts about the audience of the context. I critically examine Jeffrey King’s theory of demonstratives, which answers this question in the affirmative, and argue that it ultimately collapses into a purely speaker-based view of the character of demonstratives. I then show how to develop a much simpler speaker-based theory which both handles all of the cases handled by King’s theory and avoids some of the more serious problems which King’s theory faces. Towards the end I consider how we might solve the very difficult problems which result from cases in which speakers use demonstratives with conflicting referential intentions. (shrink)

Alvin Plantinga gave a reductio of the conjunction of the following three theses: Existentialism (the view that, e.g., the proposition that Socrates exists can't exist unless Socrates does), Serious Actualism (the view that nothing can have a property at a world without existing at that world) and Contingency (the view that some objects, like Socrates, exist only contingently). I sketch a view of truth at a world which enables the Existentialist to resist Plantinga's argument without giving up either Serious Actualism (...) or Contingency. (shrink)

However much one may wish for nonviolent solutions to the problems of unjust and unrestrained human violence that Glover explores in Humanity, some of those problems at present require violent responses. One cannot read his account of the Clinton administration’s campaign to sabotage efforts to stop the massacre in Rwanda in 1994 – a campaign motivated by fear that American involvement would cost American lives and therefore votes – without concluding that Glover himself believes that military intervention was morally required (...) in that case. Military intervention in another state that is intended to stop one group within that state from brutally persecuting or violating the human rights of members of another group is now known as “humanitarian intervention.” Those against whom the intervention is directed are almost always the government and its supporters, though this is not a necessary feature of humanitarian intervention. It is, however, a conceptual condition of humanitarian intervention that it does not occur at the request or with the consent of the government. The use of force within another state with the consent of the government counts as assistance rather than intervention. The principal reason that humanitarian intervention is contentious is that it seems to violate the target state’s sovereign right to control its own domestic affairs. Because humanitarian intervention is a response to human rights violations within the target state, it is regarded as altogether different from wars of defense against aggression. Indeed, since aggression is normally understood to be war against a state that.. (shrink)

In this article I present several challenges to the view that Shelly Kagan calls ‘modal personism’. First, there is a plausible account of our identity that, if true, greatly diminishes the scope of Kagan's view. But the scope of the view is already quite limited because the category of modal persons is restricted to those non-persons that had but have lost the potential to become persons. If the category were to include non-persons that retain the potential to become persons, Kagan's (...) view would have implausible implications about abortion and about the moral status of certain animals.

Social studies of science have often treated natural field sites as extensions of the laboratory. But this overlooks the unique specificities of field sites. While lab sites are usually private spaces with carefully controlled borders, field sites are more typically public spaces with fluid boundaries and diverse inhabitants. Field scientists must therefore often adapt their work to the demands and interests of local agents. I propose to address the difference between lab and field in sociological terms, as a difference in (...) style. A field style treats epistemic alterity as a resource rather than an obstacle for objective knowledge production. A sociological stylistics of the field should thus explain how objective science can co-exist with radical conceptual difference. I discuss examples from the Canadian North, focussing on collaborations between state wildlife biologists and managers, on the one hand, and local Aboriginal Elders and hunters, on the other. I argue that a sociological stylistics of the field can help us to better understand how radically diverse agents may collaborate across cultures in the successful production of reliable natural knowledge.

William Gilbert’s 1600 book, De magnete, greatly influenced early modern natural philosophy. The book describes an impressive array of physical experiments, but it also advances a metaphysical view at odds with the soon to emerge mechanical philosophy. That view was animism. I distinguish two kinds of animism – Aristotelian and Platonic – and argue that Gilbert was an Aristotelian animist. Taking Robert Boyle as an example, I then show that early modern arguments against animism were often effective only against Platonic (...) animism. In fact, unacknowledged traces of Aristotelian animism can be found in Boyle’s mechanical account of nature. This was Gilbert’s legacy. (shrink)

Should we accept that different moral norms govern our treatment of human and nonhuman animals? In this paper I suggest that the answer is both yes and no. At the theoretical level of morality, a single, unified set of norms governs our treatment of all sentient beings. But at the practical level of morality, different sets of norms can govern our treatment of different groups in different contexts. And whether we accept that we should, say, respect rights or maximize utility (...) at the theoretical level, we might also accept that we should apply a relatively Kantian set of norms to our treatment of humans and a relatively utilitarian set of norms to our treatment of nonhumans in practice, with many caveats. I argue that this moderate “monist in theory, hybrid in practice” view has many advantages over fully monist or hybrid alternatives. (shrink)

Some linguistic phenomena can occur in uses of language in thought, whereas others only occur in uses of language in communication. I argue that this distinction can be used as a test for whether a linguistic phenomenon can be explained via Grice’s theory of conversational implicature. I argue further, on the basis of this test, that conversational implicature cannot be used to explain quantifier domain restriction or apparent substitution failures involving coreferential names, but that it must be used to explain (...) the phenomenon of referential uses of definite descriptions. I conclude with a brief discussion of the relevance of this point to the semantics/pragmatics distinction. (shrink)

This is a position paper concerning the role of empirical studies of human default reasoning in the formalization of AI theories of default reasoning. We note that AI motivates its theoretical enterprise by reference to human skill at default reasoning, but that the actual research does not make any use of this sort of information and instead relies on intuitions of individual investigators. We discuss two reasons theorists might not consider human performance relevant to formalizing default reasoning: (a) that intuitions (...) are sufficient to describe a model, and (b) that human performance in this arena is irrelevant to a competence model of the phenomenon. We provide arguments against both these reasons. We then bring forward three further considerations against the use of intuitions in this arena: (a) it leads to an unawareness of predicate ambiguity, (b) it presumes an understanding of ordinary language statements of typicality, and (c) it is similar to discredited views in other fields. We advocate empirical investigation of the range of human phenomena that intuitively embody default reasoning. Gathering such information would provide data with which to generate formal default theories and against which to test the claims of proposed theories. Our position is that such data are the very phenomena that default theories are supposed to explain. (shrink)

In our paper, we argue for three necessary conditions for morally permissible animal research: (1) an assertion (or expectation) of sufficient net benefit, (2) a worthwhile-life condition, and (3) a no-unnecessary-harm/qualified-basic-needs condition. We argue that these conditions are necessary, without taking a position on whether they are jointly sufficient. In their excellent commentary on our paper, Matthias Eggel, Carolyn Neuhaus, and Herwig Grimm (hereafter, the authors) argue for a friendly amendment to one of our three conditions. In particular, they argue (...) for replacing the first condition—expectation of sufficient net benefit (ESNB)—with an expectation of knowledge production (EKP). In this reply, we will explain why we are open to this proposed amendment, but not yet convinced. (shrink)

Hermeneutic studies of science locate a circle at the heart of scientific practice: scientists only gain knowledge of what they, in some sense, already know. This may seem to threaten the rational validity of science, but one can argue that this circle is a virtuous rather than a vicious one. A virtuous circle is one in which research conclusions are already present in the premises, but only in an indeterminate and underdeveloped way. In order to defend the validity of science, (...) the hermeneuticist must describe a method by which a vague and confused initial knowledge of nature gets transformed into a clear and determinate knowledge of nature. I consider three such methods. The first is regressus demonstrativa, favoured by the physicians of Padua during the fifteenth and sixteenth centuries. The second is mathēsis, introduced by Martin Heidegger in his discussion of seventeenth-century science. The third is Denkstil, a key concept in Ludwik Fleck’s history of syphilology. I conclude by listing three desiderata for a hermeneutic science studies: that it be anti-metaphysical, historical, and sociological. --- Reprinted in: Erich Otto Graf, Martin Schmid & Johannes Fehr (eds.), Fleck and the Hermeneutics of Science (Collegium Helveticum Heft 14) (Zürich, 2016), pp. 85-93.

The aim of this article is to establish—and explore—James Baldwin’s significance for educational theory. Through a close reading of ‘Everybody’s Protest Novel’, I show that Baldwin’s thinking is an important precursor to the work of Stanley Cavell and Cora Diamond, and is relevant to a number of problems that are educationally significant, in particular problems of race and racism.

This chapter briefly summarises work by four key figures in the phenomenological philosophy of science: Edmund Husserl; Martin Heidegger; Patrick Heelan; and Joseph J. Kockelmans. In addition, some comparison is made with well-known figures in mainstream philosophy of science, and suggestions are given for further readings in the phenomenological philosophy of science.

Vagueness: an expression is vague if and only if it is possible that it give rise to a “borderline case.” A borderline case is a situation in which the application of a particular expression to a (name of) a particular object does not generate an expression with a definite TRUTH-VALUE. That is, the piece of language in question neither applies to the object nor fails to apply.

In "Truth and Meaning", Davidson suggested that a truth theory can do the work of a theory of meaning: it can give the meanings of expressions of a language, and can explain the semantic competence of speakers of the language by stating information knowledge of which would suffice for competence. From the start, this program faced certain fundamental objections. One response to these objections has been to supplement the truth theory with additional rules of inference (e.g. from T-sentences to meaning (...) theorems). I argue that these modifications of Davidson's original idea fail to solve the problems with Davidsonian semantics, and that the prospects for a solution to these problems within the Davidsonian framework are dim. A general lesson to be drawn is that Davidsonian theories do not provide a viable alternative to Russellian and Fregean approaches to semantics which recognize the reality of language-independent contents.

Review of David Chalmers' _The Character of Consciousness_.

In the fusillade he lets fly against Foss (1984), Bourgeois (1987) sometimes hits a live target. I admit that I went beyond the letter of van Fraassen's The Scientific Image (1980), making inferences and drawing conclusions which are often absurd. I maintain, however, that the absurdities must be charged to van Fraassen's account. While I cannot redress every errant shot of Bourgeois, his essay reveals the need for further discussion of the concepts of the phenomena and the observables as used (...) by van Fraassen. (shrink)

Aron Gurwitsch’s Gestalt-inspired “field theory of consciousness” was introduced in the same period as Wolfgang Köhler’s theory of “electrical brain fields.” I consider parallels between these theories, drawing on results that have emerged in the last five years. First, I consider the claim that fields of consciousness supervene on electromagnetic fields in the brain, then I outline Gurwitsch’s field theory of consciousness, and finally I consider how the structures described by Gurwitsch might relate to structures in the brain’s electro-magnetic field. (...) Along the way, I expose a dogma (that qualia are paradigmatic conscious states) and develop an interpretation of Gurwitsch’s field theory. (shrink)

In response to Anderson and Arzyutov’s paper, I argue that ambiguities in the Russian social-scientific concept of “etnos” reveal its place in what I call a “field style” for thinking and doing science. Tolerance for ambiguity is, I suggest, a methodological strength of the field sciences. I support these reflections by also addressing the etnos concept’s origins in the complex history of Ukrainian nationalism.

Colin Howson argues that (1) my sociologistic reliabilism sheds no light on the objectivity of epistemic content, and that (2) sorites does not threaten the reliability of modus ponens . I reply that argument (1) misrepresents my position, and that argument (2) is beside the point.

In response to arguments against the existence of God, and in response to perceived conflicts between divine attributes, theists often face pressure to give up some pretheoretically attractive thesis about the divine attributes. One wonders: when does this unacceptably water down our concept of God, and when is it, as van Inwagen says, ‘permissible tinkering’ with the concept of God? A natural and widely deployed answer is that it is permissible tinkering iff it is does not violate the claim that (...) God is the greatest possible being. Call this the ’perfect being defense.’ In this paper I lay out some influential uses of the perfect being defense, and then argue that this strategy for defending theism fails. (shrink)

Terry Horgan and Mark Timmons have recently provided an updated presentation and defense of a metaethical view that they call cognitivist expressivism. Expressivists claim that moral judgments express propositional attitudes that do not represent or describe the external world. Horgan and Timmons agree with this claim, but they also deny the traditional expressivist claim that moral judgments do not express beliefs. On their view, moral judgments are genuine, truth-apt beliefs, thus making their form of expressivism a cognitivist one. In this (...) essay, I argue that Horgan and Timmons have failed to demonstrate that moral judgments express sui generis, nondescriptive content by showing that at least some moral content is descriptive. In addition, I show how the descriptivist can account for those properties that Horgan and Timmons consider distinctive of moral belief. In doing so, I remove one of the expressivist's most important lines of motivation for positing nondescriptive moral content in the first place. At the end of the essay, I briefly sketch a view that I call partial or modest moral realism. (shrink)

This article addresses the pressing issue of what process courts should use to identify those questions whose resolution lies beyond their appropriate capacity and legitimacy. The search for such a process is a basic constitutional problem that has defied a clear answer for well over a hundred years. The chequered history of earlier attempts illustrates why commentators have once again begun to gravitate towards institutional approaches. The general features of institutional approaches include emphasis on uncertainty, judicial fallibility, systemic impact, collaboration (...) between branches of government and incrementalism in judging. These features, however, are relied upon in support of two conflicting views of the role of judges in public law adjudication. One is restrictive, and advocates sharp limitations to the ambit of judicial review. The other is contextual, and, in stark contrast, it proposes to expand the ambit of review in reliance on the idea of using principles of restraint to structure the exercise of judicial discretion. While this article does not take sides between them, it nonetheless seeks to refine the contextual institutional approach by outlining a general framework for reasoning with principles of restraint, and by addressing some of the key difficulties such a reasoning process would face.

Avia Pasternak’s book makes a significant contribution to our understanding of citizen responsibility for historical wrongs. This review nevertheless offers some scepticism about resting citizen liability exclusively on the idea of intentional participation. It argues that the necessity of the state possessing continuing legal responsibility over time is so intrinsic to the function of statehood that the question of citizen liability should be seen as part of the general theory of political obligation. So seen, fair play duties provide a more (...) plausible general ground for citizen liability, even when adapted to unjust regimes. The model of intentional participation may by contrast harbour a muted connection between the ideas of blameworthiness and responsibility that the book in the main wishes to deny. And the practical problems of resting responsibility on intentional participation alone are substantial. Pasternak’s major contribution, untouched by this critique, is to explain how the special obligations undertaken by intentional citizenship strengthen and extend beyond that more foundational duty of responsible citizens.

Game theory studies the choices of two or more agents strategically interacting under various conditions. This paper examines two applications of omniscience in game theory. The first has to do with the paradox of altruism. The paradox of altruism results when players, by seeking to maximize the outcomes of other players, bring about inferior outcomes for all the players. Not surprisingly, an omniscient player could not find herself ensnarled in an altruistic paradox. The second application is what Steven Brams has (...) called the “paradox of omniscience”. The paradox of omniscience is the surprising proposition that omniscience disadvantages a player in certain games if her opponent knows that she is omniscient. Contrary to Brams, I argue that there is no resolution of the paradox of omniscience with regard to normal games. Indeed, I show that omniscience is not the only divine property that is a strategic liability in normal games. Omniscience then has a mixed standing in game theory—in some cases a strategic asset; in others, a strategic liability. (shrink)

Next SectionCharlie Pelling presents an impropriety paradox for the truth account of assertion. After solving his paradox I show that it is a version of the liar paradox.

Second, it turns to those papers that examine the foundational role that human needs play in MacIntyre’s ethics. Third, it places in dialogue those papers that defend MacIntyre’s politics as a form of (...) ‘revolutionary Aristotelianism’ with those that contest the soundness of this categorization. (shrink)

The article features an analytic protocol for examining controversial criminal cases in critical thinking courses. The rubric has been designed to be useful to busy critical thinking teachers who wish to draw on student interest in true crime.

Due to their generality, the guidelines can be readily applied to a wide-range of cases, giving educators a high degree of (...) flexibility in the selection of criminal affairs. (shrink)

I knew that this was a book a long time in the making, and one that bore the mark of many years of teaching the philosophy discussed in the work.

In the essay I argue that the routine use of contraception is morally tantamount to early-term abortion because it produces the same result: namely, it prevents the creation of a human life that would have otherwise probably taken place. Because it can be shown that contraception is ethically acceptable, it follows that early-term abortion is as well.

Castoriadis’s radical ontology of indeterminacy postulates a third term between the complete determinacy of the traditional conception of being and the absolute indeterminacy of the traditional conception of nothingness. Castoriadis himself made considerable efforts to demonstrate how ontological conceptions which equate being with determinacy fail to grasp the reality of being in all ontological regions and contexts. He did somewhat less in regard to the opposite pole of the ontological dichotomy, the identification of indeterminacy with nothingness, though he certainly recognized (...) this identification as equally suspect.This article examines the use and interpretation of the concept of nothingness in two of the most important and exemplary employments of this concept in twentieth century philosophy. Nothingness is a key concept for both Heidegger and Sartre, however they may differ in regards to its meaning and significance. In both, the concept of nothingness disguises indeterminate modes of being which both perceive but which they refuse to accord the status of being, preferring instead the stark and absolute opposition between being, which continues to be understood in traditional terms as determinacy, and nothingness, a catch-all category which absorbs and homogenizes anything falling short of the absolute determinacy predicated of true being.

Some philosophers, most notably Julian Savulescu, have argued that potential parents have a moral reason to do what they can to have a child with the highest expected level of well-being.1 This is not just a reason to do what will make a particular child better off than he or she would otherwise be but also a reason to choose, from among different possible children, the one that has the highest expected well-being. The claim that potential parents have such a (...) reason is then often deployed as a premise in arguments in support of genetic enhancement. Robert Sparrow has argued in response that this claim implies that potential parents have a reason to choose to have female children only, primarily because women are genetically disposed to live, on average, 3–7 years longer than men.2 He takes this implication to be a reductio of this particular form of argument in support of human enhancement. In her paper, Sexual dimorphism and human enhancement, Paula Casal seeks to rebut Sparrow's argument and then goes on to suggest that a better case for the selection of female children could be made on grounds of moral enhancement, since women are far less genetically disposed to be violent and aggressive than men.3 Recognising, however, that the creation of only female children would lead to human extinction, she concludes that the way to achieve the best outcome would be to use techniques of genetic modification, should they become available, to make men more like women in certain respects: smaller, less aggressive, less competitive, less violent, less obsessed with sex, less prone to taking great risks, and less likely to die early from accident, combat, or disease.Like Larry Temkin, I am largely in agreement with Casal on these matters.

Some content externalists claim that if C is a theoretical concept and “C” expresses C, then the content of C in a community at a time is determined by how some members of the community at the time—call them “experts”—understand C or use “C”. Thus, when non-expert Chauncey utters “C”, the content of the concept he expresses does not depend entirely on his intrinsic physical properties, contra the claims of content internalism. This paper proposes that “concept” expresses a theoretical concept, (...) such that the externalist’s insights should apply to how we understand claims expressing the view itself and to how we evaluate the arguments alleged to motivate it. With respect to the first, I argue that the content externalist should regard it as unclear at present which proposition her theory expresses, and should take it that content externalism teaches us about our linguistic community rather than about the metaphysical nature of concepts. With respect to the second, I argue that by externalism’s own lights, the famous externalist thought experiments shouldn’t establish content externalism. In conclusion, I suggest that making sense of content externalism requires presupposing internalism. (shrink)

Bruineberg et al. argue that one ought not confuse the map (model) for the territory (reality) and delineate a distinction between innocuous Pearl blankets and metaphysically laden Friston blankets. I argue that all we have are models, all knowledge is conditional, and that if there is a Pearl/Friston distinction, it is a matter of the domain of application: latents or observations. This suggests that, if anything, Friston blankets may inherit philosophical significance previously assigned to observations.

: The paper's first interest is in re-forming exploitive human-environment relations. It shows that culture/nature dichotomies are not only false, but obscure the commonality of culture to humans and nonhuman beings and processes. The paper draws upon the Roman genesis of "culture" to describe its function in finding appropriateness among co-evolving human and nonhuman projects. Culture, thus, is the process through which co-eval projects are brought together. The study argues that through dialectic interrelationships, culture works to move biospheric relations towards (...) mutualism and away from parasitism (or exploitation). This is evident among nonhuman beings and processes as well as cultures in which humans are more central. The paper draws upon various interrelationships in the Mississippi watershed to illustrate these points. It then briefly explores the usefulness of a culture of nature perspective in planning and managing development projects. (shrink)
