Moderate structural realism about space-time

This paper sets out a moderate version of metaphysical structural realism that stands in contrast to both the epistemic structural realism of Worrall and the—radical—ontic structural realism of French and Ladyman. According to moderate structural realism, objects and relations (structure) are on the same ontological footing, with the objects being characterized only by the relations in which they stand. We show how this position fares well as regards philosophical arguments, avoiding the objections against the other two versions of structural realism. In particular, we set out how this position can be applied to space-time, providing for a convincing understanding of space-time points in the standard tensor formulation of general relativity as well as in the fibre bundle formulation.     

Can religious arguments persuade?

In his famous essay “The Ethics of Belief,” William K. Clifford claimed “it is wrong always, everywhere, and for anyone, to believe anything upon insufficient evidence.” (Clifford’s essay was originally published in Contemporary Review in 1877; it is presently in print in Madigan (1999)). One might claim that a corollary to Clifford’s Law is that it is wrong, always, everywhere, and for anyone, to withhold belief when faced with sufficient evidence. Seeming to operate on this principle, many religious philosophers—from St. Anselm to Alvin Plantinga—have claimed that non-believers are psychologically or cognitively deficient if they refuse to believe in the existence of God, when presented with evidence for His existence in the form of relevant experience or religious arguments that are prima facie unassailable. Similarly, many atheists fail to see how believers can confront the problem of evil and still assert their belief in a benevolent, omnipotent, and omniscient Creator. In this paper, I propose to explain why religious arguments so often fail to persuade (I take the term ‘religious argument’ to include arguments whose conclusions are either assertions or denials of religious claims). In doing so, I first offer an account of persuasion and then apply it to religious arguments. I go on to argue that at least some religious arguments commit a form of question-begging, which I call “begging the doxastic question.”~An argument begs the doxastic question, on my account, when a subject would find the argument persuasive only if she antecedently believes the argument’s conclusion. This form of question begging is not, strictly speaking, a case of circularity and thus, is not a fallacy; rather, it would explain why one coming to the argument would fail to be persuaded by it unless he already accepted its conclusion. This has the effect, when applied to religious argumentation, that religious arguments are rarely persuasive, which raises the further question: what good are religious arguments? I end by suggesting some non-persuasive functions of religious argument. Finally, I suggest that a full understanding of religious argumentation should give evidentialists pause, for religious beliefs look less like belief states that are sensitive to evidentiary states and more like framework principles or fundamental commitments.     

How is the question ‘Is Existence a Predicate?’ relevant to the ontological argument?

It is often said that the ontological argument fails because it wrongly treats existence as a first-level property or predicate. This has proved a controversial claim, and efforts to evaluate it are complicated by the fact that the words ‘existence is not a property/predicate’ have been used by philosophers to make at least three different negative claims: (a) one about a first-level phenomenon possessed by objects like horses, stones, you and me; (b) another about the logical form of assertions of existence; and (c) still another about a second-level phenomenon possessed by concepts when they are instantiated. I argue that only the last of these claims, originally voiced by Kant, is both plausible and relevant to the ontological argument. And I try to show that the relevance of the Kantian version comes from its providing the underlying justification for a different, and far less controversial, criticism of the ontological argument.     

Transcendental Arguments and Practical Reason in Indian Philosophy

This paper examines some Indian philosophical arguments that are understandable as transcendental arguments—i.e., arguments whose conclusions cannot be denied without self-contradiction, insofar as the truth of the claim in question is a condition of the possibility even of any such denial. This raises the question of what kind of self-contradiction is involved—e.g., pragmatic self-contradiction, or the kind that goes with logical necessity. It is suggested that these arguments involve something like practical reason—indeed, that they just are arguments against the primacy of “theoretical reason.” This characterization illuminates a characteristically Indic appeal to ordinary language.

Ethical Naturalism and Moral Twin Earth

In order to rebut G. E. Moore’s open question argument, ethical naturalists adopt a theory of direct reference for our moral terms. T. Horgan and M. Timmons have argued that this theory cannot be applied to moral terms, on the ground that it clashes with competent speakers’ linguistic intuitions. While Putnam’s Twin Earth thought experiment shows that our linguistic intuitions confirm the theory of direct reference, as applied to ‘water’, Horgan and Timmons devise a parallel thought experiment about moral terms, in order to show that this theory runs against our linguistic intuitions about such terms. My claim is that the Horgan–Timmons argument does not work. I concede that their thought experiment is a good way to test the applicability of the theory of direct reference to moral terms, and argue that the upshot of their experiment is not what they claim it is: our linguistic intuitions about Moral Twin Earth are parallel to, not different from, our intuitions about Twin Earth.

The Knowledge Argument against Physicalism: Its Proponents and Its Opponents

The knowledge argument usually takes the form of a thought experiment where the subject, having some psychological deficiency, lacks any introspective data to derive the knowledge of her experience. Most defenders of the knowledge argument see the argument as both a support of dualism and an objection to any full-blooded form of physicalism. However, this paper argues that the knowledge argument against physicalism may be directed, in an exactly parallel form, against reductive dualism; moreover, although most physicalists who are the opponents of the knowledge argument do not give any convincing response to the knowledge argument, some kinds of physicalism can live with the knowledge argument.     

The Comparative Set Fallacy

This paper argues for the validity of inferences that take the form of: A is more X than B; therefore A and B are both X. After considering representative counterexamples, it is claimed that these inferences are valid if and only if the comparative terms in the inference are taken from no more than one comparative set, where a comparative set is understood to be comprised of a positive, comparative, and superlative, represented as {X, more X than, most X}. In all instances where arguments appearing to be of this form are invalid, it is the case that the argument has fallaciously taken terms from more than one comparative set. The fallacy of appealing to more than one comparative set in an inference involving comparative terms is shown to be analogous to the fallacy of equivocation in argumentation. The paper concludes by suggesting a conflation of logical issues with grammatical issues is the core difficulty leading some to consider inferences in the form of A is more X than B; therefore A and B are X to be invalid.     

Plato on the role of contradiction in education

In this paper, I will look at two passages from the discussion of education in Book VII of Plato’s Republic: 523b-524d and 537e-539d. These passages, when taken together, present a puzzle for the coherency of the educational programme Socrates describes. Both discuss contradiction. One says that contradiction is educationally edifying, the other, that it is corrupting. This sounds like a contradiction about contradiction. As far as I know, no one has noticed this puzzle before. By the end of this paper, I hope to have not only provided a solution to the apparent contradiction about contradiction that is compelling, but also one that shows that this puzzle, which might at first have seemed restricted to a textual issue about the educational programme in the Republic, is in fact one that has far reaching implications for a range of Plato’s theories across several dialogues. Along with education, corruption, and contradiction, I will discuss Plato’s theory of psychology, and his theory of forms.
