In the Synopsis to the Meditations Descartes assures us that ‘extensive doubt… [provides] the easiest route by which the mind may be led away from the senses’ (12). And in the Fifth Replies Descartes adds that it is essential to a proper understanding of the Meditations that ‘the entire testimony of the senses should be regarded as uncertain and even as false’ (350). But to deny our ordinary trust in the senses on the grounds of such ‘hyperbolic’ or ‘metaphysical’ doubts as that one might be dreaming or the victim of an evil demon is, as Descartes himself puts it, quite mad: ‘no sane person has ever seriously doubted that there really is a world and that human beings have bodies’ (16). We seem, then, to be confronted with a dilemma: on the one hand, the skepticism about the senses that we find in the First Meditation must be taken seriously. On the other hand, it is, in some sense, a sham. How, then, are we to understand these doubts?

The majority of philosophers believe that the existence of spatially coincident entities is not only a coherent idea but that there are millions of such entities. What such philosophers do not countenance are spatially coincident entities of the same kind. We will call this ‘Locke's Thesis’ since the denial goes back to An Essay Concerning Human Understanding. It is there that Locke wrote, ‘For we never finding, nor conceiving it possible that two things of the same kind should exist in the same place at the same time, we rightly conclude that, whatever exists anywhere at any time, excludes all of the same kind, and is there itself alone.’ It is not clear to me that the believer in spatially coincident entities can draw the ‘ontological line’ where Locke does. Many of the reasons that lead Locke and others to maintain that there exist spatially coincident entities of different kinds would also suggest that there are spatially coincident entities of the same kind. To illustrate this claim, a scenario of spatially coincident roads will be presented.

Faced with interminable combat over some piece of philosophical terrain, someone will inevitably suggest that the contested ground is nothing more than a philosophically manufactured mirage that is therefore not worth fighting for. Arthur Fine has long advocated such a response — the ‘Natural Ontological Attitude,’ or NOA — to the realism debate in the philosophy of science. Notwithstanding the prima facie incompatibility between the realist's and anti-realist's positions, Fine suggests that there is in fact enough common ground for NOA to stand on its own as a minimal alternative, one that enjoys the advantage of being free of the philosophical burdens of its overweight contenders.

Notwithstanding Fine's claim to have identified a position that is neither realist nor anti-realist, critics charge that NOA, as Fine describes it, is a realist position. I endorse this criticism below, with attention to the relation between NOA and Bas van Fraassen's Constructive Empiricism (CE). I show that Fine's repudiation of the globalism he identifies in realism (and in anti-realism) does not insulate him from that charge.

Our topic is the ontology and persistence conditions of material objects. One widely held doctrine is that identity-over-time has causal commitments. Another is that identity-over-time is just identity (simpliciter) as it relates one object that exists at two times. We believe that a tension exists between these two apparently sensible positions: very roughly, if identity is the primary conceptual component of identity-over-time and—as is plausible—identity is noncausal, then the conceptual origins of the causal commitments of identity-over-time become a mystery. We will begin by formulating the two widely held doctrines and our puzzle more fully and more carefully. Then, the remainder of the paper will be devoted to analyzing views one might adopt that could minimize the tension.

Despite all the attention given to Kant's universalizability tests, one crucial aspect of Kant's thought is often overlooked. Attention to this issue, I will argue, helps us resolve two serious problems for Kant's ethics. Put briefly, the first problem is this: Kant, despite his stated intent to the contrary, doesn't seem to use universalization in arguing for duties to oneself, and, anyway, it is not at all clear why duties to oneself, should be grounded on a procedure that envisions a world in which everyone wills the contrary of those duties.

It is unclear in the Groundwork exactly what Kant takes to be necessary for an act to be morally good or worthy. Traditionally it has been thought that for Kant there are two conditions: it is 1) done in accord with duty, or the moral law, and 2) done for the sake of duty alone. The second condition is commonly thought to entail that an act is not morally good if the agent has a ‘supporting inclination’ or desire to do what is right — be it an inclination of self-interest, or one stemming from some emotion of ‘fellow feeling,’ such as sympathy, compassion, or love. Recent Interpreters, however, claim that Kant is not so strict, because for him the mere presence of a supporting inclination does not necessarily impugn the moral goodness of a dutiful act.

Near the end of the long and often convoluted discussion of freedom in the chapter ‘Of Power’ in An Essay concerning Human Understanding, Locke states that in ‘The care of ourselves, that we mistake not imaginary for real happiness, is the necessary foundation of our liberty’ (E 266). He goes on to explain that ‘we are by the necessity of preferring and pursuing true happiness as our greatest good, obliged to suspend the satisfaction of our desire in particular cases’ (E 266). Locke then adds that the ability to suspend our desires in particular cases is ‘the hinge on which turns the liberty of intellectual Beings’ (E 266).

The Duisburg Nachlaβ is a bundle of Kant's handwritten notes (R4674- 4684 in volume 17 of the Academy Edition). These notes almost certainly go back to some time in 1775. Though very obscure, they replay issues in Kant's early metaphysics just as clearly as they anticipate issues in the Critique of Pure Reason. This makes them an important way-station in Kant's philosophical development — all the more important, because he published nothing in the 1770s and left no other extended writings in his own hand. A proper understanding of the Duisburg Nachlaβ might therefore explain some of Kant's later ideas: their origins in his earlier thinking and their philosophical motivations. The purpose of this paper is to lay the groundwork for such an explanation—at least a partial one. I shall argue that Kant's efforts in the Duisburg Nachlaβ to correct certain difficulties in the Inaugural Dissertation of 1770 anticipate and naturally lead to the crucial claim in the Critique of Pure Reason that the understanding legislates laws to nature (A125-128; B163-165).

Possession and control of an object enhance the freedom of its holder. Property protects this freedom; but it restricts the freedom of ail others. Drawing the boundaries of freedom with respect to external objects is a central and difficult challenge for libertarians. What justifies my ownership of, say, the cup I am drinking from? Several possible answers come to mind: answers based on need, on welfare, on desert or on equality. None of these is endorsed by the libertarian; none of these, arguably, can justify private property in the cup. From a proprietarian point of view the legitimacy of any holding derives from the moral power of its previous owner. An owner has the power of transfer, the power to make another person the owner. What justifies my ownership of the cup is the exercise of the power of the person who gave it to me; his ownership was justified by the exercise of the power of the person who sold it to him; the latter's ownership was justified by the exercise of the power of the person who bequeathed it to him; and so on and so forth. But series of transfers of this kind, long as they may be, must come to an end. There must have been a point where something not privately owned became the private property of an individual or group.

Libertarians must assert a principle of just appropriation. Such a principle specifies the ways in which a person can come to own a natural resource which was previously not (privately) owned.

In the lengthy debate over the question of scientific realism one of the least discussed positions is structural realism. However, this position ought to attract critical attention because it purports to preserve the central insights of the best arguments for both realism and anti-realism. John Worrall has in fact described it as being ‘the best of both worlds’ that recognizes the discontinuous nature of scientific change as well as the ‘no-miracles’ argument for scientific realism. However, the validity of this claim has been called into question by Stathis Psillos. He questions its ability to correctly account for the examples of scientific change that its supporters, like Worrall (following Poincaré), claim ought to be understood in a structural realist light.

In this paper I examine these arguments for and against structural realism and demonstrate that neither Worrall nor Psillos is fully correct. I agree with Psillos’ claim that realism with regards to a theory ought not to be ‘all or nothing,’ that one should not always take the whole of a theory to be true or else commit only to the belief in its directly empirical content.

In ‘What's Puzzling Gottlob Frege?’ Michael Thau and Ben Caplan argue that, contrary to the common wisdom, Frege never abandoned his early view that, as he puts it in Begriffsschrift, a Statement of identity ‘expresses the circumstance that two names have the same content’ and thus asserts the existence of a relation between names rather than a relation between (ordinary) objects. The arguments at the beginning of ‘On Sense and Reference’ do, they agree, raise a problem for that view, but, they insist, Frege does not, as the ‘standard’ Interpretation has it, take these arguments to refute it. Rather, they claim, Frege is out to defend (a version of) his earlier view against these objections: indeed, the defense he there offers is pretty much the same defense offered in Begriffsschrift against what are pretty much the same objections.

A growing number of political and legal theorists deny that there is a widespread duty to obey the law. This has lent a sense of urgency to recent disagreements about whether a state's legitimacy depends upon its ‘subjects’’ having a duty to obey the law. On one side of the disagreement, John Simmons, Robert Paul Wolff, David Copp, Hannah Pitkin, Leslie Green, George Klosko, and Joseph Raz hold that a state could only be legitimate if the vast majority of its subjects have a duty to obey the law. On the other side, M.B.E. Smith, Jeffrey Reiman, Kent Greenawalt, Christopher Morris, Rolf Sartorius, Jeremy Waldron, Christopher Wellman, William Edmundson and Allen Buchanan claim that a state could be legitimate even if its subjects lacked a duty to obey the law.

This disagreement contains two separate disputes. One is a linguistic dispute about the meaning of ‘legitimacy,’ or about what it means to call something a ‘legitimate state.’ The other is a Substantive dispute about whether the various aspects of legitimacy are linked together. Since discussing the linguistic dispute will help us examine the Substantive dispute, let us consider it first.

It is a common antirealist strategy to reject realism about some domain of entities for broadly epistemological reasons. When this strategy is applied to realism about moral facts, it takes something like the following form:

In numerous essays over the years, and most recently in his Meaning, Paul Horwich has worked to articulate and defend a version of the use theory of meaning. At the heart of his project is the idea that the meaning of a word is constituted by a regularity in speakers’ use of it — i.e., by a regularity in speakers’ dispositions to accept as true, to reject as false, or neither to accept nor to reject sentences containing it. A ‘use regularity,’ thus construed, is a dispositional acceptance property distinctive of a particular word and, derivatively, of sentences containing the word.

Pornography may harm women in a variety of ways. But among the harms that pornography has sometimes been alleged to cause is a surprising one: it violates women's right to freedom of speech. Pornography ‘silences’ women; and laws against pornography are justified (among other reasons) in order to stop pornographers from expressing themselves in a way that prevents women from speaking. Or so claims Catherine Mackinnon.

On Kant's view, the feeling of respect is the mark of moral agency, and is peculiar to us, animals endowed with reason. Unlike any other feeling, respect originates in the contemplation of the moral law, that is, the idea of lawful activity. This idea works as a constraint on our deliberation by discounting the pretenses of our natural desires and demoting our selfish maxims. We experience its workings in the guise of respect. Respect shows that from the agent's subjective perspective, morality is the experience of being bound and necessitated, but also of being free and emancipated from inclinations.

Respect is a feeling that is generated by the agent's reflection on the nature of her own agency. It is not directed to anybody in particular, but to the very idea of rational agency, which is characterized by self-mastery and self-legislation. Contrary to animals, we do not derive our ends from nature, but we are capable of setting ends of our own, by exercising practical reason, that is, by engaging in the activity of law making.

The word ‘consciousness’ is notoriously ambiguous. This is mainly because it is not a term of art, but a mundane word we all use quite frequently, for different purposes and in different everyday contexts. In this paper, I am going to discuss consciousness in one specific sense of the word. To avoid the ambiguities of the word ‘consciousness,’ I will introduce a term of art: intransitive self-consciousness. As the term suggests, the phenomenon I have in mind is a kind of self-consciousness, or self-awareness.
