One of the fundamental theses of Gadamer’s philosophical hermeneutics is that all knowledge is historically conditioned. This thesis appears to be self-refuting. That is, it appears to contradict itself insofar as its assertion that every knowledge claim is historically conditioned seems to assert an absolute, unconditionally true knowledge claim. If the historicity thesis does, in fact, refute itself in this way, then that spells trouble for philosophical hermeneutics. Gadamer was well aware of this, and so he attempts in several passages (...) to respond to this charge of self-contradiction. Those passages, however, are brief and difficult to understand. They consequently have been either neglected or inadequately understood. This paper makes better sense of those passages in order to defend Gadamer’s historicity thesis as coherent. (shrink)

Free will sceptics claim that we lack free will, i.e. the command or control of our conduct that is required for moral responsibility. There are different conceptions of free will: it is sometimes understood as having the ability to choose between real options or alternatives; and sometimes as being the original or true source of our own conduct. Whether conceived in the first or in the second way, free will is subject to strong sceptical arguments. However, free will sceptics face (...) a difficulty: doubting the existence of free will might itself be problematic, whether free will exists or not. Three main considerations are offered in support of this claim. Firstly, it is said that free will sceptics confuse contexts: even if they are right to doubt the existence of free will in the philosophy classroom, they are wrong to do so in other contexts, such as day-to-day interactions or a court of law. Secondly, it is said that free will scepticism is incompatible with inescapable and indispensable human practices such as practical deliberation or moral criticism and evaluation. For, to deliberate about what to do, we must presume that we have true options or alternatives. And to judge that some human practices are wrong, we need to assume the existence of moral responsibility. Thirdly, free will scepticism is sometimes said to be self-defeating, on the grounds that it cannot be rational to believe free will scepticism, because free will is required for rationality. This thesis critically assesses these arguments. None takes free will scepticism down, but all are instructive about how not to be a sceptic. They trace the ‘contours’ of free will scepticism by discrediting some conceptions of free will and some arguments for free will scepticism. (shrink)

We have no reason to believe that reasons do not exist. Contra Bart Streumer’s recent proposal, this has nothing to do with our incapacity to believe this error theory. Rather, it is because if we know that if a proposition is true, we have no reason to believe it, then we have no reason to believe this proposition. From a different angle: if we know that we have at best misleading reasons to believe a proposition, then we have no reason (...) to believe it. This has two consequences. Firstly, coming close to believing the error theory is idle or pointless. Secondly, philosophers who argue that believing sweeping theories like determinism or physicalism is self-defeating because they are either false or believed for no reason pursue a worthwhile argumentative strategy.

This article aims at reconstructing the logic and assessing the force of Socrates' argument against Protagoras' 'Measure Doctrine' at Theaetetus 171a–c. I examine and criticise some influential interpretations of the passage, according to which, e.g., Socrates is guilty of ignoratio elenchi by dropping the essential Protagorean qualifiers or successfully proves that md is self-refuting provided the missing qualifiers are restored by the attentive reader. Having clarified the meaning of MD, I analyse in detail the broader section 170a–171d and argue, against (...) an extensive scholarly consensus, that it contains two slightly different formulations of the same argument, and not two distinct arguments, that Socrates does not highlight his own strategy at 171a–c as especially clever, and that his argument successfully shows that md turns out to be untenable for Protagoras himself when submitted to scrutiny in dialectical contexts, without aiming at proving its absolute falsehood. Finally, I clarify the philosophical import of the final image of Protagoras' momentary return from the underworld. (shrink)

Self-defeating and self-justifying expressions are reflexive insofar as they pertain to themselves. However, the reflexivity involved is often pragmatic, i.e., does not entirely depend upon the logical properties of what is expressed but also upon the expressive act. In this paper I present a general account of pragmatic reflexivity and apply it to some familiar self-defeating and self-justifying expressions in epistemology. This application indicates some important, if often neglected features of the epistemological issues involved. The account I defend suggests that (...) epistemology is particularly sensitive to pragmatic reflexivity since what epistemologists do, i.e., inquire, theorize, and defend theories, is also the subject of the inquiry and resultant theories.
