In this essay, we explore a fresh avenue into mind-body dualism by considering a seemingly distant question posed by Frege: "Why is it absurd to suppose that Julius Caesar is a number?". The essay falls into three main parts. In the first, through an exploration of Frege’s Julius Caesar problem, we attempt to expose two maxims applicable to the mind-body problem. In the second part, we draw on those maxims in arguing that “full blown dualism” is preferable to more modest, property-theoretic, versions. Finally, in the third part we close by suggesting that full blown dualism need not be spooky, resurrecting a broadly Lockean, rather than Cartesian, metaphysical picture.

The need to address our question arises from two sources, one in Kant and the other in a certain type of response to so-called Reformed epistemology. The first source consists in a tendency to distinguish theoretical beliefs from practical beliefs , and to treat theistic belief as mere practical belief. We trace this tendency in Kant's corpus, and compare and contrast it with Aquinas's view and a more conservative Kantian view. We reject the theistic-belief-as-mere-practical-belief view: it is bad descriptive anthropology, it embraces a misguided ideal of a fragmented self unattainable by human beings, and it will deter people from the most desirable sort of faith. The second source consists in the idea that since theistic beliefs function as answers to why-questions, their epistemic status hangs on whether they meet certain distinctively explanatory standards, whatever support they might receive from other sources. We argue that this is a non-sequitur and suggest questions for further research

The argument is not, however, problem-free. First: while the meaning of s might not guarantee a verifying state of affairs, mightn’t the fact of one’s believing that s is true guarantee a verifying state of affairs? And mightn’t this fact be exploited to secure knowledge of truths that are deeply contingent? Second: the argument seems to rely on the principle that if I can conceive that not P is actually the case, then I do not know that P. But it is generally agreed that a knowledge-conferring warrant for some P need not offer a watertight guarantee of P and thus need not render it inconceivable that the actual world falsifies P. Why then require such a guarantee when it comes to priori warrant? The first objection is that a guarantee of truth need not come from semantics. The second is that no such guarantee is required for a priori knowledge. I shall be exploring both of these ideas in what follows.

[John Hawthorne] We examine some well-known disjunctivist projects in the philosophy of perception, mainly in a critical vein. Our discussion is divided into four parts. Following some introductory remarks, we examine in part two the link between object-dependent contents and disjunctivism. In part three, we explore the disjunctivist's use of discriminability facts as a basis for understanding experience. In part four, we examine an interesting argument for disjunctivism that has been offered by Michael Martin. /// [Scott Sturgeon] The paper aims to do five things: sketch the backbone of disjunctivism about visual experience, explore the view of our title, defend a version of that view from two objections, press two more objections of my own, and sketch a more radical variety of disjunctivism which avoids much of the bother.

The need to address our question arises from two sources, one in Kant and the other in a certain type of response to so-called Reformed epistemology. The first source consists in a tendency to distinguish theoretical beliefs from practical beliefs (commitments to the world's being a certain way versus commitments to certain pictures to live by), and to treat theistic belief as mere practical belief. We trace this tendency in Kant's corpus, and compare and contrast it with Aquinas's view and a more conservative Kantian view. We reject the theistic-belief-as-mere-practical-belief view: it is bad descriptive anthropology, it embraces a misguided ideal of a fragmented self unattainable by human beings, and it will deter people from the most desirable sort of faith. The second source consists in the idea that since theistic beliefs function as answers to why-questions, their epistemic status hangs on whether they meet certain distinctively explanatory standards, Whatever support they might receive from other sources.

In his recent book, Daniel Korman contrasts ontological conservatives with permissivists and eliminativists about ontology. Roughly speaking, conservatives admit the existence of ‘ordinary objects' like trees, dogs, and snowballs, but deny the existence of ‘extraordinary objects', like composites of trees and dogs. Eliminativists, on the other hand, deny many or all ordinary objects, while permissivists accept both ordinary and extraordinary objects. Our aim in this paper is to outline some of our reasons for being drawn to permissivism, as well as some of our misgivings about conservative metaphysics. In the first section, we discuss a tempting epistemic line of argument against conservatism. This isn’t a line of argument we find especially promising. Our most basic complaint against conservatism is not that conservatism has poor epistemic standing even if true, but instead that conservatism is weird. We develop this thought in the second part of the paper. In the final section we discuss some larger methodological issues about the project of ontology.

Scotus contended that the humanity of Socrates has less than a numerical unity. But what does that claim come to? And how does Scotus’s position relate to familiar debates concerning the existence of universals and/or tropes? This paper provides a detailed sketch of Scotus’s view, arguing that it is not intrinsic to Socrates’s nature that it has numerical unity. The paper goes on to explain why Ockham’s attack on the coherence of Scotus’s argument does not succeed. What initially looks like a successful master argument against Scotus’s view is ultimately a failure on account of its neglect of the role of intrinsic determination.

We see things. We also perceptually demonstrate things. There seems to be some sort of link between these two phenomena. Indeed. in the standard case, the former is accompanied by a capacity for the latter. One sees a dog and can, on the basis of one’s perceptual capacities, think thoughts of the form ‘That is F’. But how strong is that link? Does seeing a thing (in the success sense of seeing) inevitably bring with it the capacity for perceptually demonstrating it? In what follows, we argue for a negative answer to this question. In so doing, we hope to shed some light on the phenomenon of perceptual demonstration. After presenting the main argument in section one, we go on in section two to consider a series of objections and replies.

Epistemicism is one of the main approaches to the phenomenon of vagueness. But how does it fare in its treatment of_ moral_ vagueness? This paper has two goals. First, I shall explain why various recent arguments against an epistemicist approach to moral vagueness are unsuccessful. Second, I shall explain how, in my view, reflection on the Sorites can inform normative ethics in powerful and interesting ways. In this connection, I shall be putting the epistemicist treatment to work, engaging with a family of somewhat neglected issues concerning continuity that lie at the interface of metaphysics and ethics.

Assuming that we find the concept of naturalness coherent, we shall no doubt wish to allow that certain relations count as highly natural. Many of us will think that various spatio-temporal and causal relations—is the cause of, is spatially separated from, is later than—are highly natural. Some of us will think that various basic semantic and mentalistic relations—refers to, attends to, believes.…--- are highly natural. Some will think that various logico-mathematical relations—being the successor of, being identical to…—are highly natural.

This article examines the methodology of a core branch of contemporary political theory or philosophy: “analytic” political theory. After distinguishing political theory from related fields, such as political science, moral philosophy, and legal theory, the article discusses the analysis of political concepts. It then turns to the notions of principles and theories, as distinct from concepts, and reviews the methods of assessing such principles and theories (e.g., the reflective-equilibrium method), for the purpose of justifying or criticizing them. Finally, it looks at a recent debate on how abstract and idealized political theory should be, and assesses the significance of disagreement in political theory. The discussion is carried out from an angle inspired by the philosophy of science.

Certain passages in Kaplan’s ‘Demonstratives’ are often taken to show that non-vacuous sentential operators associated with a certain parameter of sentential truth require a corresponding relativism concerning assertoric contents: namely, their truth values also must vary with that parameter. Thus, for example, the non-vacuity of a temporal sentential operator ‘always’ would require some of its operands to have contents that have different truth values at different times. While making no claims about Kaplan’s intentions, we provide several reconstructions of how such an argument might go, focusing on the case of time and temporal operators as an illustration. What we regard as the most plausible reconstruction of the argument establishes a conclusion similar enough to that attributed to Kaplan. However, the argument overgenerates, leading to absurd consequences. We conclude that we must distinguish assertoric contents from compositional semantic values, and argue that once they are distinguished, the argument fails to establish any substantial conclusions. We also briefly discuss a related argument commonly attributed to Lewis, and a recent variant due to Weber.
