An essay concerning humane understanding. In four books

London: Printed for Awnsham and John Churchill, 1706. FIFTH EDITION. Index bound after Contents and before text. Contemporary full-paneled calf, panels blind-stamped on front and rear boards, edges partially rubbed with corners reinforced, rebacked; interior excellent. Fifth edition, containing expansions of all four books. This edition includes the final textual changes by Locke, though it was published posthumously. It was also the last edition printed in folio format. Locke’s (1632-1704) famous work of empirical philosophy deals with the fundamental issues of how we think, perceive, and express ourselves through language, logic and religion. All later editions were based upon this 1706 printing.
