In this book, Henrik Lagerlund offers students, researchers, and advanced general readers the first complete history of what is perhaps the most famous of all philosophical problems: skepticism. As the first of its kind, the book traces the influence of philosophical skepticism from its roots in the Hellenistic schools of Phyrronism and the Middle Academy up to its impact inside and outside of philosophy today. Along the way, it covers skepticism during the Latin, Arabic, and Greek Middle Ages and during the Renaissance before moving on to cover Descartes's methodological skepticism and Pierre Bayle's super-skepticism in the seventeenth century. In the eighteenth century, it deals with Humean skepticism and the anti-skepticism of Reid and Kant, taking care to also include reflections on the connections between idealism and skepticism. The book covers similar themes in a chapter on G.E. Moore and Ludwig Wittgenstein, and then ends its historical overview with a chapter on skepticism in contemporary philosophy. In the final chapter, Lagerlund captures some of skepticism's impact outside of philosophy, highlighting its relation to issues like the replication crisis in science and knowledge resistance.

Within much contemporary epistemology, Kant’s response to skepticism has come to be epitomized by an appeal to transcendental arguments. This form of argument is said to provide a distinctively Kantian way of dealing with the skeptic, by showing that what the skeptic questions is in fact a condition for her being able to raise that question in the first place, if she is to have language, thoughts, or experiences at all. In this way, it is hoped, the game played by the skeptic can be turned against herself.1 At the same time, however, this appeal to transcendental arguments is also widely felt to show what is wrong with Kant’s response to skepticism: for, it is suggested, such arguments can only be made to work against the background of his transcendental idealism. As we shall see, what this doctrine amounts to is much disputed; but as with any form of idealism, the worry is that it means compromising the very realism and objectivity we want to defend against skepticism in the first place, so that the price for adopting this Kantian strategy appears too high—the cure of using transcendental arguments in conjunction with transcendental idealism is almost as bad as the disease.2 Faced with this difficulty, two kinds of response have been canvassed. On the first, it is accepted that transcendental arguments do require a commitment to the wider philosophical framework of transcendental idealism, but it is claimed that this framework can and should be defended against the suggestion that it is itself ‘‘quasi-skeptical.’’ On the second, transcendental idealism is indeed abandoned as wrongheaded, but it is held that Kant’s transcendental arguments can be made to..
