Many epistemologists think we can derive important theoretical insights by investigating the English word ‘know’ or the concept it expresses. However, fewer than six percent of the world’s population are native English speakers, and some empirical evidence suggests that the concept of knowledge is culturally relative. So why should we think that facts about the word ‘know’ or the concept it expresses have important ramifications for epistemology? This paper argues that the concept of knowledge is universal: it is expressed by some word in every natural language. I also explore the implications of this thesis for philosophical methodology.

As current events around the world have illustrated, epistemological issues are at the center of our political lives. It has become increasingly difficult to discern legitimate sources of evidence, misinformation spreads faster than ever, and the role of truth in politics has allegedly decayed in recent years. It is therefore no coincidence that political discourse is currently saturated with epistemic notions like ‘post-truth,’ ‘fake news,’ ‘truth decay,’ ‘echo chambers,’ and ‘alternative facts.’ This book brings together leading philosophers to explore ways in which the analytic and conceptual tools of epistemology bear on political philosophy, and vice versa. It is organized around three broad themes: truth and knowledge in politics; epistemic problems for democracy; and disagreement and polarization. The authors provide new and rich insights on topics such as: propaganda, fake news, weaponized skepticism, belief polarization, political disagreement, the epistemic value of democracy, voter ignorance, irrationality in politics, political bullshit, and identity politics.

I acquired many intellectual debts while writing What’s the Point of Knowledge?, but I am especially indebted to my three symposiasts. David Henderson’s work helped me to appreciate the value of thinking about the point of epistemic evaluation; Catherine Elgin’s writings prompted me to investigate the purpose of the concept of understanding; and Krista Lawlor’s 2013 book revealed important connections between three of my primary epistemological interests: the role of epistemic evaluation, the semantics of knowledge claims and the work of J.L. Austin. It is therefore an honour to have such personally influential scholars engage with my work. Their thoughtful, generous and philosophically rich comments have provided yet another opportunity to clarify my thinking and develop some ideas further.

This article summarizes the key ideas in my book, ‘What's the Point of Knowledge?’. First, I articulate the method of function first epistemology, which looks at our epistemology from a practical point of view. Second, I outline my core hypothesis about the purpose of the concept of knowledge, namely, we have this concept to identify reliable informants. Third, I explain how this account is used to resolve a number of epistemological issues. I also draw connections between pragmatism and my own theory of knowledge.
