This title opens up the debate into the nature of skill, skilfulness and expertise in vocational and professional education. A detailed philosophical debate on the nature of expertise is long overdue and "Dimensions of Expertise" opens up that debate. Christopher Winch firstly explores an account of know-how, derived primarily from the pioneering work of Gilbert Ryle, and moves on to relate this epistemological debate to discussions concerning the nature of expertise in vocational and professional education, including attempts to provide a theory of expertise.
