In this article I attempt to show that a phenomenon in visual perception called change blindness poses a problem for this doctrine. Specifically, I argue that phenomenal character is not sensitive, as it should be if reductive intentionalism is correct, to fine-grained variations in content. The standard antiintentionalist strategy is to adduce putative cases in which phenomenal character varies despite sameness of content. This paper explores an alternative antiintentionalist tack, arguing, by way of a specific example involving change blindness, that content can vary despite sameness of phenomenal character.

Specifically, it is argued that if we accept Pascal’s premises, then we can infer that the god for whom Pascal encourages us to wager is irrational. But if God is irrational, then the prudentially rational course of action is to refrain from wagering for him.

For example, assuming that language use is a rule-governed activity, what facts determine that a speaker's current usage of a word accords with her previous usage or, in terms of rulefollowing, what facts determine that the rule a speaker is following in her current usage of a word is equivalent to the rule she followed in her previous usage of the word? Kripke reads Wittgenstein as articulating this problem most perspicuously in the form of a paradox in §201 of the Investigations: This was our paradox: no course of action could be determined by a rule, because every course of action can be made out to accord with the rule. The answer was: if everything can be made out to accord with the rule, then it can also be made out to conflict with it. And so there would be neither accord nor conflict here. According to Kripke, this paradox "may be regarded as a new form of philosophical scepticism" (RPL: 7), since it casts doubt on whether there are any facts that determine that we are following a rule and, by extension, whether it is possible by means of the notion of rule-following to make sense of the claim that we mean one thing rather than another. Kripke proceeds to develop the skeptical paradox in a form that challenges the possibility of any language, public or

Two underlying assumptions motivate this approach to phenomenal character: (1) that conscious experiences are diaphanous or transparent, in the sense that it is impossible to discern, via introspection, any intrinsic features of an experience of x that are not experienced as features of x; and (2) that the immediate objects of consciousness are not objects per se, but rather properties. This paper explores these assumptions, advancing the thesis that each is rejectable on phenomenological grounds.

This paper mounts a case for the thesis that these attributes are incompatible. More exactly, it provides compelling evidentiary support for the claim that, given the basic structure of consciousness, it is impossible for a psychological being to be disembodied (and vice versa). But if it is impossible for a psychological being to be disembodied (and vice versa), then, since psychologicality and disembodiment are both essential to God under classical theism, the God of classical theism does not—and cannot—exist.
Frankfurt Cases, Alternate Possibilities, and Prior Signs

According to a compelling (yet relatively under-discussed) response to Frankfurt’s attack on PAP, Frankfurt has not succeeded in showing that the principle is false, since in the scenario he asks us to imagine the agent has an alternate possibility: he can (unwittingly) force the intervener’s hand by revising his decision to perform the action in question and thereby avoid performing the action himself. This response to Frankfurt has been objected to, however, on the grounds that the agent does not avoid performing the action since the intervener acts upon an involuntary prior sign. The goal of this article is to show that this objection fails. While it is true that the prior sign upon which the intervener acts is involuntary, it is a consequence of a change of mind that is voluntary. It follows that the agent does what is needed to avoid performing the action in question (in the counterfactual sequence).

Though neither of these theses is novel, there is a dearth of direct arguments for them in the scholarly literature and the relationship between them has so far gone underrecognized. This article attempts to remedy this lack, advancing the claim that if all conscious states have phenomenal character, then all state consciousness involves self-consciousness.

Despite its title, it is more than a specialist tome devoted to an historically isolable development, and it is not merely a subsidiary, underlaborer's attempt to recount the prehistory of Kant's achievement. Rather, by tracing several important background currents through the period concerned, Hochstrasser illuminates the odd historical fact that German enlighteners at the end of this span knew or thought so little of those at its beginning. The central topics are eclecticism; the so-called “histories of morality” that were part of its self-conscious legitimation method; the rationalism-voluntarism split in early modern natural law; and the associated distinction among moral philosophy (ethics), natural (positive) law, and international law (ius gentium) that devel...

Specifically, in the penultimate chapter entitled "Reductionism," they argue that NM is unintelligible, that "there is no sense to literally identifying neural states and configurations with psychological attributes." This is a provocative claim indeed. If Bennett and Hacker are right, then a sizeable number of philosophers, cognitive scientists, neuroscientists, etc., subscribe to a view that is not merely false, but strictly meaningless. In this article I show that Bennett and Hacker's arguments against NM, whether construed as arguments for the meaninglessness of or the falsity of the thesis, cannot withstand scrutiny: when laid bare they are found to rest upon highly dubious assumptions that either seriously mischaracterize or underestimate the resources of the thesis.
