The goal of inquiry is to acquire knowledge of truths about the world. In this book, Jason Stanley argues that knowing how to do something amounts to knowing a truth about the world. When you learned how to swim, what happened is that you learned some truths about swimming, including a special kind of truth about it that answers the question, ‘How could you swim?’ Know How develops an account of the kinds of answers to questions, knowledge of which explains skilled action. Stanley presents a powerful case that it is our success as inquirers that explains our capacity for skilful engagement with the world.
