John Locke is probably one of the highest-regarded English philosophers, and the first of the British empiricists. His ideas on the mind and consciousness have continued to resonate throughout philosophy and philosophical thought ever since An Essay Concerning Human Understanding first appeared in 1690. James Gibson's Locke's Theory of Knowledge and its Historical Relations was first published in 1917, and saw its fourth reprinting in 1968. Here, it is made available for the first time in paperback. This hugely detailed work is an invaluable collation of Locke's theories, exploring his thoughts on the problems of knowledge, the formation of ideas, causality and the self. Furthermore, Gibson also provides an in-depth historical evaluation of the effects of these theories on contemporary philosophy as a whole, and on thinkers such as Descartes, Kant and Leibniz more specifically. As such, this book is a valuable reference work for any student of philosophy.
