Conditional Excluded Middle

In this essay I renew the case for Conditional Excluded Middle (CXM) in light of recent developments in the semantics of the subjunctive conditional. I argue that Michael Tooley’s recent backward causation counterexample to the Stalnaker-Lewis comparative world similarity semantics undermines the strongest argument against CXM, and I offer a new, principled argument for the validity of CXM that is in no way undermined by Tooley’s counterexample. Finally, I formulate a simple semantics for the subjunctive conditional that is consistent with both CXM and Tooley’s counterexample.

Don’t Know,Don’t Kill: Moral Ignorance,Culpability, and Caution

This paper takes on several distinct but related tasks. First, I present and discuss what I will call the “Ignorance Thesis,” which states that whenever an agent acts from ignorance, whether factual or moral, she is culpable for the act only if she is culpable for the ignorance from which she acts. Second, I offer a counterexample to the Ignorance Thesis, an example that applies most directly to the part I call the “Moral Ignorance Thesis.” Third, I argue for a principle—Don’t Know, Don’t Kill—that supports the view that the purported counterexample actually is a counterexample. Finally, I suggest that my arguments in this direction can supply a novel sort of argument against many instances of killing and eating certain sorts of animals.

On the Alleged Connection between Moral Evil and Human Freedom: A Response to Trakakis’ Third Critique

In this essay, I respond to Nick Trakakis’ “A Third (Meta-)Critique.” This critique is directed against my argument concerning the inadequacy of the traditional theistic argument from free will. I contend that the argument from free will does not adequately explain the distribution of moral evil in the world. I maintain that the third critique, like Trakakis’ earlier critiques, is unconvincing. I remain convinced that my original argument regarding the inadequacy of the traditional argument from free will is compelling. The argument from freedom of the will, considered in itself, is unpersuasive.

Response to Selinger on Dreyfus

My claim is clear and unambiguous: no machine will pass a well-designed Turing Test unless we find some means of embedding it in lived social life. We have no idea how to do this but my argument, and all our evidence, suggests that it will not be a necessary condition that the machine have more than a minimal body. Exactly how minimal is still being worked out.

Underdetermination and Rational Choice of Theories

The underdetermination of theory by data argument (UD) is traditionally construed as an argument that tells us that we ought to favour an anti-realist position over a realist position. I argue that when UD is constructed as an argument saying that theory choice is to proceed between theories that are empirically equivalent and adequate to the phenomena up until now, the argument will not favour constructive empiricism over realism. A constructive empiricist cannot account for why scientists are reasonable in expecting one theory to be empirically adequate rather than another, given the criteria he suggests for theory choice.

Trumping the causal influence account of causation

Here is a simple counterexample to David Lewis’s causal influence account of causation, one that is especially illuminating due to its connection to what Lewis himself writes: it is a variant of his trumping example

Are Our Concepts conscious state and conscious creature Vague?

Intuitively it has seemed to many that our concepts conscious state and conscious creature are sharp rather than vague, that they can have no borderline cases. On the other hand, many who take conscious states to be identical to, or realized by, complex physical states are committed to the vagueness of those concepts. In the paper I argue that conscious state and conscious creature are sharp by presenting four necessary conditions for conceiving borderline cases in general, and showing that some of those conditions cannot be met with conscious state. I conclude that conscious state is sharp, and the conclusion is then extended to conscious creature. The paper ends with a brief discussion of some implications.

Refutation by Parallel Argument

This paper discusses the method when an argument is refuted by a parallel argument since the flaw of the parallel argument is clearly displayed. The method is explicated, examined and compared with two other general methods.

Constituted Simples?

Many philosophers maintain that artworks, such as statues, are constituted by other material objects, such as lumps of marble. I give an argument against this view, an argument which appeals to mereological simples.

Single premise deduction and risk

It is tempting to think that multi premise closure creates a special class of paradoxes having to do with the accumulation of risks, and that these paradoxes could be escaped by rejecting the principle, while still retaining single premise closure. I argue that single premise deduction is also susceptible to risks. I show that what I take to be the strongest argument for rejecting multi premise closure is also an argument for rejecting single premise closure. Because of the symmetry between the principles, they come as a package: either both will have to be rejected or both will have to be revised.

The many minds account of vagueness

This paper presents an new epistemicist account of vagueness, one that avoids standard arbitrariness worries by exploiting a plenitudinous metaphysic.

That <Emphasis Type="Italic">F</Emphasis>

Jeffrey King’s principal objection to the direct-reference theory of demonstratives is analyzed and criticized. King has responded with a modified version of his original argument aimed at establishing the weaker conclusion that the direct-reference theory of demonstratives is either incomplete or incorrect. It is argued that this fallback argument also fails.

Vague terms,indexicals, and vague indexicals

Jason Stanley has criticized a contextualist solution to the sorites paradox that treats vagueness as a kind of indexicality. His objection rests on a feature of indexicals that seems plausible: that their reference remains fixed in verb phrase ellipsis. But the force of Stanley’s criticism depends on the undefended assumption that vague terms, if they are a special sort of indexical, must function in the same way that more paradigmatic indexicals do. This paper argues that there can be more than one sort of indexicality, that one term might easily have both sorts, and that therefore, and despite Stanley’s worries, vagueness might easily be assimilated to one form.

Is Equality Essentially Comparative?

Larry Temkin has shown that Derek Parfit’s well-known Mere Addition Paradox suggests a powerful argument for the intransitivity of the relation “better than.” The crux of the argument is the view that equality is essentially comparative, according to which the same inequality can be evaluated differently depending on what it is being compared to. The comparative view of equality should be rejected, I argue, and hence so too this argument for intransitivity.

Mr. Magoo’s mistake

Timothy Williamson has famously argued that the (KK) principle (roughly, that if one knows that p, then one knows that one knows that p) should be rejected. We analyze Williamson’s argument and show that its key premise is ambiguous, and that when it is properly stated this premise no longer supports the argument against (KK). After canvassing possible objections to our argument, we reflect upon some conclusions that suggest significant epistemological ramifications pertaining to the acquisition of knowledge from prior knowledge by deduction.

Media Violence and Freedom of Speech: How to Use Empirical Data

Susan Hurley has argued against a well known argument for freedom of speech, the argument from autonomy, on the basis of two hypotheses about violence in the media and aggressive behaviour. The first hypothesis says that exposure to media violence causes aggressive behaviour; the second, that humans have an innate tendency to copy behaviour in ways that bypass conscious deliberation. I argue, first, that Hurley is not successful in setting aside the argument from autonomy. Second, I show that the empirical data are irrelevant to statutory regulation of media violence. They do not yield a sufficiently strong correlation between exposure to media violence and non-autonomously copied criminal violence, and they do not yield a way ex ante to individuate the viewers who will be affected by media violence.

The Notion of Pseudo-Argument in Perelman’s Thought

According to Perelman (Rhétoriques, Presses Universitaires de Bruxelles, 1989: 80), a pseudo-argument is an argument that is supposed to be convincing from a given audience viewpoint, while it is not from another audience viewpoint. Such a claim raises the traditional problem of the boundaries between the well known “convince versus persuade” dichotomy. This paper aims at investigating it from a contemporary rhetorical and argumentative perspective which will take into account the fictional dimension of persuasion. In this perspective, it will be claimed that the notion of an “as if” argument better fits to some rhetorical phenomena.

Foot and Aristotle on Virtues and Flourishing

This article compares the views of Foot and Aristotle on virtues and flourishing. It is argued that the view put forward in Philippa Foot’s recent book, Natural Goodness, suffers from a certain sort of vagueness and it is open to other criticisms which the Aristotelian view can avoid. Foot’s views have been subjected to criticism in the recent literature by David Copp and David Sobel. These criticisms are given consideration in the article and it is argued that the more traditional Aristotelian view advocated by the author will have the means to answer some of these criticisms whereas Foot’s view will not.

Blair on Rodin: Rejoinder

The article is a brief response to Jacob Blair’s critique of David Rodin’s argument in War and Self-Defense that there are circumstances in which war conceivably could be justified not as self-defence, but as law enforcement or punishment. It argues that while Rodin’s position potentially is less dilemmatic than Blair suggests, Blair nevertheless usefully highlights tensions within it. Blair’s own argument in favour of ar as law-enforcement is suggestive, but in no way conclusive.

Towards a New Epistemology of Mathematics

In this introduction we discuss the motivation behind the workshop “Towards a New Epistemology of Mathematics” of which this special issue constitutes the proceedings. We elaborate on historical and empirical aspects of the desired new epistemology, connect it to the public image of mathematics, and give a summary and an introduction to the contributions to this issue.
