Allan Hazlett – författare

Most people have wondered whether anything really matters, some have temporarily thought that nothing really matters, and some philosophers have defended the view that nothing really matters. However, if someone thinks that nothing matters--if they are a "nihilist about value"--then it seems that it is irrational for them to care about anything. It seems that nihilism about value mandates total indifference. This is the "problem of nihilism" Allan Hazlett addresses in The Epistemology of Desire and the Problem of Nihilism. Hazlett argues that the problem of nihilism arises because desire--and thus caring--is a species of evaluation that admits of irrationality. This contradicts the influential Humean view that desire does not admit of irrationality, which has a ready solution to the problem of nihilism: since desire does not admit of irrationality, it cannot be irrational to care about something that you believe does not matter. However, following G.E. Anscombe, Hazlett argues that desire has the same relationship to goodness as belief has to truth: just as truth is the accuracy condition for belief, goodness is the accuracy condition for desire. This reveals desire as an appropriate target of epistemological inquiry, in the same way that belief is an appropriate target of epistemological inquiry. Desires can amount to knowledge (in the same way that beliefs can amount to knowledge) and, crucially for the problem of nihilism, desire admits of irrationality (in the same way that belief admits of irrationality). Nevertheless, although it is obviously irrational to believe something that you believe is not true, Hazlett argues that it is not irrational to desire something you believe is not good, despite the fact that goodness is the accuracy condition for desire. This provides a solution to the problem of nihilism, and shows that nihilism about value can coherently be combined with the anti-Humean view that desire is a species of evaluation.

The value of true belief has played a central role in history of philosophy--consider Socrates' slogan that the unexamined life is not worth living, and Aristotle's claim that everyone naturally wants knowledge--as well as in contemporary epistemology, where questions about the value of knowledge have recently taken center stage. It has usually been assumed that accurate representation--true belief--is valuable, either instrumentally or for its own sake. In A Luxury of the Understanding, Allan Hazlett offers a critical study of that assumption, and of the main ways in which it can be defended. Hazlett defends the conclusion that true belief is at most sometimes valuable. In the first part of the book, he targets the view that true belief is normally better for us than false belief, and argues that false beliefs about ourselves--for example, unrealistic optimism about our futures and about other people, such as overly positive views of our friends--are often valuable vis-à-vis our wellbeing. In the second part, he targets the view that truth is "the aim of belief," and argues for anti-realism about the epistemic value of true belief. Together, these arguments comprise a challenge to the philosophical assumption of the value of true belief, and suggest an alternative picture, on which the fact that some people love truth is all there is to "the value of true belief".

Skepticism remains a central and defining issue in epistemology, and in the wider tradition of Western philosophy. To better understand the contemporary position of this important philosophical subject, Allan Hazlett introduces a range of topics, including:• Ancient skepticism• skeptical arguments in the work of Hume and Descartes• Cartesian skepticism in contemporary epistemology• anti-skeptical strategies, including Mooreanism, nonclosure, and contextualism• additional varieties of skepticism• the practical consequences of Cartesian skepticismPresenting a comprehensive survey of the key problems, arguments, and theories, together with additional readings, A Critical Introduction to Skepticism is an ideal guide for students and scholars looking to understand how skepticism is shaping epistemology today.
