About This Item

London: Printed for J. Johnson, W.J. and J. Richardson, W. Otridge and Son, F.C. and J. Rivington, et. al, 1805. Twenty-first Edition. Hardcover. Very Good. 2 vol. 8vo. [9], 8-510, [4]; [17], 2-459, [29] pp. Full tree calf with board edges gauffered, spines decorated and lettered in gilt, each with a black morocco label. Illustrated with a large fold-out plate in volume one, "An Analysis of Mr. Locke's Doctrine of Ideas". The Twenty-First Edition, to which are now added An Analysis of Mr. Locke's Doctrine of Ideas, on a large sheet, A Defence of Mr. Locke's Opinion Concerning Personal Identity, with an Appendix, A Treatise on the Conduct of the Understanding, Some Thoughts Concerning Reading and Study for a Gentleman, Elements of Natural Philosophy, and A New Method of a Common-Place Book. Collation matches what is called for in Yolton for the nineteenth and twentieth editions (published in 1793 and 1796 respectively), except for the printers marks. Yolton does not call for frontispieces in the volumes. Printed by Bye and Law, St. John's Square, Clerkenwell. Yolton 87, 89. A lovely set of Locke's magnum opus: an extraordinarily influential work in modern philosophy. A Very Good set with scattered light foxing and age toning, two small tears to the fold-out Analysis of Locke's View on Ideas, some rubbing and wear to the extremities (very minor loss to the label on volume two), and a tiny hole on the front board of volume one.


An Essay Concerning Human Understanding is one of John Locke's two most famous works, the other being his Second Treatise on Civil Government. First appearing in 1690, the essay concerns the foundation of human knowledge and understanding. He describes the mind at birth as a blank slate (tabula rasa, although he did not use those actual words) filled later through experience.
