Empiricisms is about the value of experience and experiments. Why do we esteem them and what is their contribution to knowledge? The work is unique in the detail with which it explains empiricism, from its beginning in ancient medicine to its emergence as a philosophy of modern science. It elucidates the ideas of the so-called radical empiricists, clarifying their relation to historical empiricism, and explaining what is "radical" about them, and develops a
comparison between European empiricism and ideas and practice in traditional China. Bringing China into the argument is an unexpected innovation, and makes the work a model for comparative philosophy.
