Throughout history skepticism and the urge to question accepted truths has been a powerful force for change and growth. Today, as we are bombarded by adverts, scientific studies praising the latest superfoods, and political rhetoric, a healthy amount of skepticism is widely encouraged. But when is such skepticism legitimate-for example, as a driver of new ideas-and when is it problematic? And what role might adopting a skeptical outlook play in leading an intellectually virtuous life?
In this Very Short Introduction Duncan Pritchard explores both the advantages of skepticism, in challenging outdated notions, and also how it can have unhelpful social consequences, in generating distrust. He considers the role of skepticism at the source of contemporary social and political movements such as climate change denial, post-truth politics, and fake news. Pritchard also examines the philosophical arguments for a radical form of skepticism which maintains that knowledge is impossible, and explores some of the main responses to these arguments. Finally, he considers the part skepticism might play in applying better thinking and learning to achieve a more meaningful life.
