This book considers the important twentieth century Austrian philosopher, Ludwig Wittgenstein, and his conception of certainty. In his work entitled On Certainty, Wittgenstein provides not only a brilliant solution to a previously intractable philosophical problem, but also the elements of an entirely new way of approaching this and similar longstanding, apparently unresolvable, problems. In On Certainty, he re-conceives the problem of radical skepticism-the claim that we can never really be certain of anything except the contents of our own minds-as a kind of philosophical "disease" of thought. His approach to the problem, which is emphasized in the book, is similar to the treatment of disease, has two main goals: (1) bring about an awareness in the philosopher that this kind of extreme skepticism is not a methodological approach to be taken seriously, and, with this awareness, (2) an attempt to replace this radical skepticism with a practical, Common Sense framework. Implicit in Wittgenstein's approach are a number of strategies found in a contemporary approach to psychotherapy known as Cognitive Behavioral Therapy (CBT). These strategies, along with philosophical methods and scientific practices rooted in the Scottish School of Common Sense, seek to diagnose and treat irrational thoughts and beliefs that often emerge (and re-emerge) in the discipline of philosophy. The aim of this book, then, is to provide students of philosophy with the tools necessary to adjust and reshape these irrational, self-defeating thoughts and beliefs into something new, something healthy.

Ludwig Wittgenstein's On Certainty explores a myriad of new and important ideas regarding our notions of belief, knowledge, skepticism, and certainty. During the course of his exploration, Wittgenstein makes a fascinating new discovery about certitude, namely, that it is categorically distinct from knowledge. As his investigation advances, he recognizes that certainty must be non-propositional and non-ratiocinated; borne out not in the things we say, but in our actions, our deeds. Many philosophers working outside of epistemology recognized Wittgenstein's insights and determined that his work's abrupt end might serve as an excellent launching point for still further philosophical expeditions. In Exploring Certainty: Wittgenstein and Wide Fields of Thought, Robert Greenleaf Brice surveys some of this rich topography. Wittgenstein's writings serve as a point of departure for Brice's own ideas about certainty. He shows how Wittgenstein's rough and unpolished notion of certitude might be smoothed out and refined in a way to benefit studies of morality, aesthetics, cognitive science, philosophy of mathematics. Brice's work opens new avenues of thought for scholars and students of the Wittgensteinian tradition, while introducing original philosophies concerning issues central to human knowledge and cognition.
