Current Research

I work in epistemology, especially the social and political aspects of epistemology. Most of my research explores the relationship between knowledge and practical life.

I also dabble in cognitive science, ethics, and philosophy of language.

The Role of Truth in Politics

I am at the early stages of writing a book about the role of truth in politics. Much has been written about the post-truth world of fake news, dodgy experts, and “alternative facts.” But journalists and academic commentators have largely ignored recent philosophical insights about the nature of deep disagreements, the dangers of thinking for oneself, and the ways in which knowledge can actually be harmful to democracy.

Unlike many scholars, I do not rush to truth’s defense. This book’s central thesis is that, in many situations, we should relegate the role of truth in political life. Instead we should focus on deferring to appropriate authorities, the role of emotion in politics, and fostering mutual understanding.
