Knowledge how to do things is a pervasive and central element of everyday life. Yet it raises many difficult questions that must be answered by philosophers and cognitive scientists aspiring to understand human cognition and agency. What is the connection between knowing how and knowing that? Is knowledge how simply a type of ability or disposition to act? Is there an irreducibly practical form of knowledge? What is the role of the intellect in intelligent action? This volume contains fifteen state of the art essays by leading figures in philosophy and linguistics that amplify and sharpen the debate between "intellectualists" and "anti-intellectualists" about mind and action, highlighting the conceptual, empirical, and linguistic issues that motivate and sustain the conflict. The essays also explore various ways in which this debate informs central areas of ethics, philosophy of action, epistemology, philosophy of language, and philosophy of mind and cognitive science.
