This target article presents a new computational theory of explanatory coherence that applies to the acceptance and rejection of scientific hypotheses as well as to reasoning in everyday life, The theory consists of seven principles that establish relations of local coherence between a hypothesis and other propositions. A hypothesis coheres with propositions that it explains, or that explain it, or that participate with it in explaining other propositions, or that offer analogous explanations. Propositions are incoherent with each other if they (...) are contradictory, Propositions that describe the results of observation have a degree of acceptability on their own. An explanatory hypothesis is acccpted if it coheres better overall than its competitors. The power of the seven principles is shown by their implementation in a connectionist program called ECHO, which treats hypothesis evaluation as a constraint satisfaction problem. Inputs about the explanatory relations are used to create a network of units representing propositions, while coherende and incoherence relations are encoded by excitatory and inbihitory links. ECHO provides an algorithm for smoothly integrating theory evaluation based on considerations of explanatory breadth, simplicity, and analogy. It has been applied to such important scientific cases as Lovoisier's argument for oxygen against the phlogiston theory and Darwin's argument for evolution against creationism, and also to cases of legal reasoning. The theory of explanatory coherence has implications for artificial intelligence, psychology, and philosophy. (shrink)

There has recently been a growing interest in the topic of vagueness and indeterminacy in contemporary metaphysics, with two views taking center stage. The semantic view holds that indeterminacy is due to vagueness in the extension of concepts, while the ontological view holds that indeterminacy is due to the vagueness of certain objects. There has, however, been little research on discussions of vagueness and indeterminacy in early-modern philosophy despite the relevance of vagueness and indeterminacy for issues such as real and (...) nominal definitions, clear and distinct ideas, and the principle of complete determination. In this paper, I survey discussions of vagueness in Locke, Leibniz, and Kant and point to ways in which the problem of vagueness and indeterminacy touches on broader issues in their respective philosophies. Although Locke, Leibniz, and Kant all suggest that vagueness is a semantic phenomenon, Kant also appears to countenance an ontological view according to which objects as appearances may sometimes be indeterminate.

Kant’s claim in the Subjective Deduction that we have multiple fundamental mental powers appears to be susceptible to some a priori metaphysical arguments made against multiple fundamental mental powers by Christian Wolff who held that these powers would violate the unity of thought and entail that the soul is an extended composite. I argue, however, that in the Second Paralogism and his lectures on metaphysics, Kant provides arguments that overcome these objections by showing that it is possible that a composite (...) could ground the unity of thought, that properties are powers and therefore the soul could possess multiple powers, and the soul is a thing in itself so it cannot be an extended composite. These arguments lend additional support to the attribution of multiple mental powers to us in the Subjective Deduction. (shrink)

In this article I reevaluate Immanuel Kant's moral philosophy from a post–Darwinian perspective. Taking an evolutionary approach to human reasoning and incorporating some recent work on the science of the emotions, I argue that the Kantian bifurcation of reason and emotion, which underlies his moral philosophy, is no longer tenable. Kant's practical defense of his ethics as being the only option that can save morality from the dangers posed by naturalism is also considered and rejected. Instead, I argue that an (...) evolutionary view of reason and emotion can provide an adequate ground for morality and explore the possibility and advantages of such an ethics. (shrink)

With the publication of A Theory of Justice in 1971, John Rawls not only rejuvenated contemporary political philosophy but also defended a Kantian form of Enlightenment liberalism called “justice as fairness.” Enlightenment liberalism stresses the development and exercise of our capacity for autonomy, while Reformation liberalism emphasizes diversity and the toleration that encourages it. These two strands of liberalism are often mutually supporting, but they conflict in a surprising number of cases, whether over the accommodation of group difference, the design (...) of civic education, or the promotion of liberal values internationally. During the 1980’s, however, Rawls began to jettison key Kantian characteristics of his theory, a process culminating in the 1993 release of Political Liberalism and completing the transformation of justice as fairness into a Reformation liberalism. -/- Reconstructing Rawls argues that this transformation was a tragic mistake because it jeopardized the most important features of his theory, viz. the lexical priorities of right, liberty, and fair equality of opportunity as well as the difference principle. Controversially, this book contends that Rawls’s so-called “political turn,” motivated by a newfound interest in diversity and the accommodation of difference, has been unhealthy for autonomy-based liberalism and has pushed liberalism more broadly towards cultural relativism, be it in the guise of liberal multiculturalism or critiques of cosmopolitan distributive-justice theories. The book then demonstrates that the central elements of justice as fairness can only be defended within the context of a Kantian Enlightenment liberalism and that Rawls’s hope for a more pluralistic grounding for his theory, endorsed by a wide variety of belief systems present in modern democratic societies, is illusory. -/- Reconstructing Rawls is the first book to systematically compare Rawls’s and Kant’s theories and the first to offer an internal critique and reconstruction of justice as fairness, reconceiving it as a comprehensive, universalistic Kantian liberalism. By doing so, it gives us both the vision of a liberal world order—“a republicanism of all states, together and separately,” as Kant put it—and a mode of justification addressed to all men and women, not as members of particular nations, races, and faiths, but as human beings, as citizens of the world. In short, it reclaims Rawls for the Enlightenment. (shrink)

In this essay, I argue that Kant’s Anthropology from a Pragmatic Point of View is fundamentally about the sphere of civilization, and, with this, a particular kind of philosophical self-understanding. By civilization, Kant means to indicate the process by which human beings transform their inner natures based on pragmatic or prudential considerations born of our living together. Civilization is what we do to ourselves in order to get along with others with whom we share the earth. In the Anthropology, what (...) we come to understand about ourselves is the possibility of transforming our inner natures based on our will. (shrink)

When Kant announces in a letter to Reinhold that he has discovered a new domain of a priori principles, he situates these principles in a ‘faculty of feeling pleasure and displeasure ’. And it is indeed in his Critique of Aesthetic Judgement, named in this letter the Critique of Taste, that we find his elucidation of the relation of the principle of purposiveness to the feeling of pleasure. The kinds of judgements in which our feelings are evaluated in accordance with (...) a principle are what Kant names reflective judgements. And while reflective judgements emerge in the third Critique to include not only judgements of taste, but also judgements of the sublime and teleological judgements of nature, in this paper I will focus on the first, as the question of the relatedness of reflection to pleasure is most pronounced in this context. There is no consensus in Kant scholarship as to what the structure of reflective judgements is, as evidenced by the widely disparate views of those such as Guyer, Allison, Pippin, Ginsborg, Lyotard, and others.

This article discusses some of the ways in which natural language can express modal information – information which is, to a first approximation, about what could be or must be the case, as opposed to being about what actually is the case. It motivates, explains, and raises problems for Angelika Kratzer's influential theory of modal auxiliaries, and introduces a new approach to one important debate about the relationships between modality, evidentiality, context change, and imperative force.

According to the received opinion there is a theoretical incompatibility between Herbert Hart's The Concept of Law and Alf Ross's On Law and Justice, and, according to the received opinion, it stems above all from Hart's emphasis on the internal point of view. The present paper argues that this reading is mistaken. The Concept of Law does not go beyond On Law and Justice in so far as both present arguments to the effect that law is based on a shared (...) understanding between participants in a project perceived by every participant to be a project in common. The paper demonstrates that there are substantive parallels between Hart's combination of “acceptance” or “acknowledgement” and a “critical reflective attitude” and Ross's combination of “motivation” or “feeling” and a “coherent whole of meaning and motivation.” The main conclusion is that the views of norms and normativity put forward in The Concept of Law and On Law and Justice are very close in essential respects, and, more specifically, that the two works are at root identical in their representation of the basis of normativity in reality.

Kant's Critique of Pure Reason makes important claims about space, time and mathematics in both the Transcendental Aesthetic and the Axioms of Intuition, claims that appear to overlap in some ways and contradict in others. Various interpretations have been offered to resolve these tensions; I argue for an interpretation that accords the Axioms of Intuition a more important role in explaining mathematical cognition than it is usually given. Appreciation for this larger role reveals that magnitudes are central to Kant's philosophy (...) of mathematics and to the part that intuition plays in it. (shrink)

The aggregate EIRP of an N-element antenna array is proportional to N 2. This observation illustrates an effective approach for providing deep space networks with very powerful uplinks. The increased aggregate EIRP can be employed in a number of ways, including improved emergency communications, reaching farther into deep space, increased uplink data rates, and the flexibility of simultaneously providing more than one uplink beam with the array. Furthermore, potential for cost savings also exists since the array can be formed using (...) small apertures. (shrink)

The author explains that there is scope for a general theory about the nature and place of form in the fundamentals of law. Form organizes the institutions, rules and other varieties of law, and the system as a whole. All such constructs have non‐formal elements, too, but form unifies each construct and provides its criteria of identity. Appropriate form makes a system of law possible. It also tends to beget good content in the law. It is indispensable to the basic (...) needs of a legal system, and when such an end is organizational, as with democracy, liberty, and the rule of law, form is end as well as means. (shrink)

Quine made it conventional to portray the contradiction that destroyed Frege’s logicism as some kind of act of God, a thunderbolt that descended from a clear blue sky. This portrayal suited the moral Quine was antecedently inclined to draw, that intuition is bankrupt, and that reliance on it must therefore be replaced by a pragmatic methodology. But the portrayal is grossly misleading, and Quine’s moral simply false. In the person of others – Cantor, Dedekind, and Zermelo – intuition was working (...) pretty well. It was in Frege that it suffered a local and temporary blindness. The question to ask, then, is not how Frege was overtaken by the contradiction, but how it is that he didn’t see it coming. The paper offers one kind of answer to that question. Starting from the very close similarity between Frege’s proof of infinity and the reasoning that leads to the contradiction, it asks: given his understanding of the first, why did Frege did not notice the second? The reason is traced, first, to a faulty generalization Frege made from the case of directions and parallel lines; and, through that, to Frege’s having retained, and attempted incoherently to combine with his own, aspects of a pre-Fregean understanding of the generality of logical principles.

This version of this paper has been superseded by a substantially revised version in G. Strawson, Real Materialism and Other Essays (OUP 2008) I take 'content' in a natural internalist way to refer to occurrent mental content. I introduce a 'thin' or ‘live’ notion of the subject according to which a subject of experience cannot exist unless there is an experience for it to be the subject of. I then argue, first, that in the case of a particular experience E, (...) its content C, and its (thin) subject S, [C ↔ E ↔ S]; and, second, that the metaphysical fact that underlies this (strong modal) equivalence is in fact identity: [E = S = C]. I suggest that the effort of thought required to grasp this is deeply revealing of the nature of reality. On the way I raise a doubt about the viability of the traditional object/property distinction. -/- . (shrink)

One of the most pressing philosophical problems in early modern Europe concerned how the soul and body could form a unity, or, as many understood it, how these two substances could work together. It was widely believed that there were three (and only three) hypotheses regarding the union of soul and body: (1) physical influence, (2) occasionalism, and (3) pre-established harmony. However, in 1763, a fourth hypothesis was put forward by the French thinker André-Pierre Le Guay de Prémontval (1716–1764). Prémontval’s (...) hypothesis, given the grand name of “psychocracy” (i.e., the dominion or the rule of the soul), held that there was a real influence between soul and body, but that this was an immaterial kind of influence as opposed to the physical kind that had been entertained heretofore. Prémontval’s hypothesis is the focus of this paper. I shall begin by sketching out the details of Prémontval’s hypothesis (Section 1), then proceed to consider its claims to constitute a true fourth hypothesis distinct from the other three (Section 2), before closing by briefly considering two objections and the responses either that Prémontval himself made or that may be made on his behalf (Section 3).

Suppose that X and Y can’t possibly exist apart in reality; then—by definition—there’s no real distinction between them, only a conceptual distinction. There’s a conceptual distinction between a rectilinear figure’s triangularity and its trilaterality, for example, but no real distinction. In fundamental metaphysics there is no real distinction between an object’s categorical properties and its dispositional properties. So too there is no real distinction between an object and its properties. And in fundamental metaphysics, for X and Y to be such (...) that there is no real distinction between them is for them to be identical. (shrink)

Many philosophers claim that it cannot be the case that a person ought to perform an action if this person cannot perform this action. However, most of these philosophers do not give arguments for the truth of this claim. In this paper, I argue that it is plausible to interpret this claim in such a way that it is entailed by the claim that there cannot be a reason for a person to perform an action if it is impossible that (...) this person will perform this action. I then give three arguments for the truth of the latter claim, which are also arguments for the truth of the former claim as I interpret it. (shrink)

Philosophy is a radical inquiry whose task is to interrogate the fundamental assumptions of some given activity, discipline, or set of beliefs. In doing so, philosophical inquiry must attempt to delineate a problem and to develop a method for resolving that problem. However, to be true to its intention, philosophy must be able to examine not only the object of its inquiry but also its own method of interrogation. To accomplish this task, philosophical inquiry must be able to create a (...) distance not only from the assumptions under investigation but also from its own assumptions, which is to say, that it must be able to raise questions about its own method. This self-reflexivity requires that any given philosophical investigation must be examined from an alternative vantage point. Since the assumptions which inform the inquiry are deeply imbedded within a given culture, immanent critique is insufficient. The only way to step outside the boundaries of these cultural presuppositions is to reflect on the given problem from the vantage point of another culture's philosophical tradition. Thus, I argue that philosophical inquiry is unable to go beyond certain limits without being cross-cultural philosophy. I illustrate the way in which cross-cultural philosophy does this with respect to the problem of the self by placing the Western philosophical approach to this problem in dialogue with the Indian Hindu-Buddhist narrative.

This article seeks to recover a neglected chapter in the historical and theoretical background of social theory in general and critical theory in particular with a view to refining the understanding of the presuppositions of a cognitively enhanced critical social science appropriate to our troubled times. For this purpose, it offers a brief reconstruction of the mathematical-philosophical tradition from ancient to modern times by extrapolating that part of it that is marked by the ideas of infinity, infinite processes and limit (...) concepts. It gives suggestive indications not only of how these ideas relate to extant social-theoretical thought, but especially also of the two related cognitive directions – the weak-naturalistic and the socio-cultural – in which such thought is currently challenged to go.

I argue that Irigaray's recent work develops a theoretically cogent and politically radical form of realist essentialism. I suggest that she identifies sexual difference with a fundamental difference between the rhythms of percipient fluids constituting women's and men's bodies, supporting this with a philosophy of nature that she justifies phenomenologically and ethically. I explore the politics Irigaray derives from this philosophy, which affirms the sexes' rights to realize the possibilities of their rhythmically diverse bodies.

Authors such as Krishnasamy Selvan argue that “all human endeavors including engineering and science” have a single primary objective: “bettering humanity.” They favor discussing “the history of science and measurement uncertainty.” This paper respectfully disagrees and argues that “human endeavors including engineering and science” should not pursue “bettering humanity” as their primary objective. Instead these efforts should first pursue individual betterment. One cannot better humanity without knowing what that means. However, there is no one unified theory of what is to (...) the betterment of humanity. Simultaneously, there is no one field (neither science, nor engineering, nor philosophy) entitled to rule univocally. Perhaps if theorists tended their own gardens, the common weal would be tended thereby. (shrink)

There is good reason to suppose that religious belief and ritual are manifestations of the archetypal blueprint for human existence encoded in the genetic structure of our species. As a consequence, religion has become a focus of study for psychobiologists and neuroscientists. However, scientific explanations of religious experience do not “explain away” such experience nor are they substitutes for the experience itself. On the contrary, scientific discoveries may be seen as corroboration of religious insights into the unus mundus, the essential (...) oneness of all experience, which links human nature with the nature of the cosmos.

What is the point of developing an epistemology for a topic—for example, morality? When is it appropriate to develop the epistemology of a topic? For many topics—for example, the topic of socks—we see no need to develop a special epistemology. Under what conditions, then, does a topic deserve its own epistemology? I seek to answer these questions in this article. I provide a criterion for deciding when we are warranted in developing an epistemological theory for a topic. I briefly apply (...) this criterion to moral epistemology and argue that some approaches to moral epistemology should be abandoned. I also argue that we can develop an epistemology for a topic without committing ourselves to a specific substantive theory of justification, such as reliabilism or coherentism, if we work within a suitably neutral framework.

In this article, I want to argue that scepticism for Kant must be seen in ancient and not just modern terms, and that if we take this into account we will need to take a different view of Kant's response to Hume from the one that is standardly presented in the literature.

Against a view currently popular in the literature, it is argued that Kant was not a niıve realist about perceptual experience. Naive realism entails that perceptual experience is object-dependent in a very strong sense. In the first half of the paper, I explain what this claim amounts to and I undermine the evidence that has been marshalled in support of attributing it to Kant. In the second half of the paper, I explore in some detail Kant’s account of hallucination and (...) argue that no such account is available to someone who thinks that veridical perceptual experience is object-dependent in the naive realist sense. Kant’s theory provides for a remarkably sophisticated, bottom-up explanation of the phenomenal character of hallucinatory episodes and is crucial for gaining a proper understanding of his model of the mind and its place in nature.

This article puts forward a revisionary reading of Hegel's reception in Britain at the turn of the nineteenth century, in suggesting that the stance of the British Hegelians is very close to the sort of non-metaphysical or category theory interpretations that have been in vogue amongst contemporary commentators. It is shown that the British Hegelians arrived at this position as a way of responding to the hostile existentialist reaction to Hegel begun by Schelling in the 1840s, which led them to (...) abandon the standard Neoplatonic reading of his idealism, and arrive at the sort of non- metaphysical account which is most fully developed by J M E McTaggart in his interpretation of Hegel's Logic.

According to the ‘One Object’ reading of Kant's transcendental idealism, the distinction between the appearance and the thing in itself is not a distinction between two objects, but between two ways of considering one and the same object. On the ‘Metaphysical’ version of the One Object reading, it is a distinction between two kinds of properties possessed by one and the same object. Consequently, the Metaphysical One Object view holds that a given appearance, an empirical object, is numerically identical to (...) the thing in itself that appears as that object. I raise various indiscernibility arguments against that view; because an appearance has different spatiotemporal and modal properties than a thing in itself, no appearance can be identical to a thing in itself. I point out that these arguments are similar to arguments against Monism, the view that material objects are numerically identical to the matter of which they are made. I outline some strategies Monists have developed to respond to these indiscernibility arguments and then develop parallel responses on behalf of the Metaphysical One Object view. However, I then raise another indiscernibility argument, to which, I argue, the Metaphysical One Object view cannot respond, even using the resources I have developed thus far. I develop a modified version of the Metaphysical One Object view that can respond to this new indiscernibility argument, but, I argue, this modified version of the One Object view is only a terminological variant of the Two Object view. When the Metaphysical One Object view is fully thought through it becomes the Two Object view. I conclude that Kantian appearances are not numerically identical to the things in themselves that appear to us. (shrink)

While Peirce is a seminal figure for contemporary semiotic philosophers, it is axiomatic of a fully semiotic perspective that no philosopher or philosophy can provide any final answer, as signs are always interpreted and the context of interpretation always varies. Semiosis is evolutionary: it may or may not be construed as progressive but it cannot be static. While Peirce offers a way out of the mind-body divide that both permeates and separates classical rationalism and empiricism, he himself is read in (...) this article as closer to the rationalist tradition exemplified by Kant and Hegel that he critiques than to either thoroughgoing empiricism or post-Nietzschean relativism. From a contemporary perspective, Peirce thus falls short of qualifying as a fully semiotic thinker, notwithstanding his key role in the development of semiotic philosophy. (shrink)

In the Transcendental Ideal Kant discusses the principle of complete determination: for every object and every predicate A, the object is either determinately A or not-A. He claims this principle is synthetic, but it appears to follow from the principle of excluded middle, which is analytic. He also makes a puzzling claim in support of its syntheticity: that it represents individual objects as deriving their possibility from the whole of possibility. This raises a puzzle about why Kant regarded it as (...) synthetic, and what his explanatory claim means. I argue that the principle of complete determination does not follow from the principle of excluded middle because the externally negated or ?negative? judgement ?Not (S is P)? does not entail the internally negated or ?infinite? judgement ?S is not-P.? Kant's puzzling explanatory claim means that empirical objects are determined by the content of the totality of experience. This entails that empirical objects are completely determinate if and only if the totality of experience has a completely determinate content. I argue that it is not a priori whether experience has such a completely determinate content and thus not analytic that objects obey the principle of complete determination. (shrink)

In this paper I present and assess a controversy between Edmund Husserl and Heinrich Rickert on the nature of judgment, in order to bring to light the originality of Husserl's proposal concerning this important issue. In the first section I provide some context for Rickert's theory of judgment by sketching a reconstruction of nineteenth century logical theory and then proceed to introduce Rickert's view. I suggest that nineteenth century logic is characterized by a criticism of the traditional view that sees (...) categorial judgment as the essential form of judgment and the uniting and separating of ideas as sufficient for the constitution of a judgment. Hume inaugurates this criticism, but it finds its most mature expression in the work of Lotze, Brentano, and Rickert. Rickert, in particular, sees simple affirmation and negation of the transcendent value of truth as the essence of judgment. In the second section I present Husserl's criticism of Rickert. Husserl's criticism revolves around the distinction between simple judgments and the higher-order affirmative or negative stance we can adopt with respect to previously articulated simple judgments. Simple judgments register the mereological relation holding among something and one of its properties, and they do not entail an affirmative or negative stance. Their function is to constitute states of affairs drawing on concrete perceptual situations. Higher-order affirmation or negation occurs when we set out to revisit a foregoing simple judgment in order to confirm or disconfirm the veridicality of its proposed state of affairs. In the third part I suggest a diagnosis of the origin of the mistake in earlier theories. Simple judgments are easy to conflate with non-simple, higher-order judgmental stances because they have the same logical value and they cannot be seen without the aid of genuinely phenomenological reflection. In conclusion, I suggest that Husserl's analysis amounts to a vindication of categorial judgment in its traditional form ‘S is P’, which continues to maintain a phenomenological legitimacy even in the wake of Frege's canonical dismissal of subject and predicate.

Questions of identity such as ‘Who am I?’ are often answered by appeals to one or more affiliations with a specific nation (citizenship), culture, ethnicity, religion, etc. Taking as given the idea that identity over time—including identification and re-identification—for objects of a particular kind requires that there be criteria of identity appropriate to things of that kind, I argue that citizenship, as a ‘collectivist’ concept, does not generate such criteria for individual citizens, but that the concept person—which specifies the kind (...) of entity that I am—does generate such criteria. Confusion on this point has led some writers on citizenship to equivocate between identity for individuals and what is properly called self-determination in terms of their group affiliations and commitments. In the second part of the paper, I articulate and defend a relational view of personhood, and argue that it provides adequate grounding for morality in general, and moral education in particular. While not denying the value of civics or citizenship education, the link between morality and citizenship is derivative, at best. Finally, I examine the implications of a relational conception of personhood for the specific context of schools and classrooms, arguing that this conception is appropriately represented when the classroom functions as a community of inquiry, in which each member is encouraged to see her/himself as one among others. Drawing on the theory and practice of Philosophy for Children, I conclude with a call to reunite citizenship and moral education with their philosophical roots. (shrink)

Research on human infants has begun to shed light on early-developing processes for segmenting perceptual arrays into objects. Infants appear to perceive objects by analyzing three-dimensional surface arrangements and motions. Their perception does not accord with a general tendency to maximize figural goodness or to attend to nonaccidental geometric relations in visual arrays. Object perception does accord with principles governing the motions of material bodies: Infants divide perceptual arrays into units that move as connected wholes, that move separately from one (...) another, that tend to maintain their size and shape over motion, and that tend to act upon each other only on contact. These findings suggest that o general representation of object unity and boundaries is interposed between representations of surfaces and representations of objects of familiar kinds. The processes that construct this representation may be related to processes of physical reasoning. (shrink)

: Wittgenstein raises the notion of "conversion" in philosophy through his claims that philosophical understanding is a matter of the will rather than the intellect. Soulez examines this notion in Wittgenstein's philosophy through a series of reflections on the aims and methodology of his philosophical "grammar," in relation to comparable models among Wittgenstein's contemporaries (Freud, James) and from the history of philosophy (Saint Augustine, Descartes).
