    A Critical Introduction to Skepticism

    A Critical Introduction to Skepticism

    By Allan Hazlett

    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 skepticism

    Presenting 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.

    A Luxury of the Understanding

    A Luxury of the Understanding

    By Allan Hazlett

    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.
