In matching contemporary full mottled calf, spines raised and decoratively tooled with gilt, marbled end papers, red page edges, place-marking blue ribbon. Vol. I with 345 pages, Vol. II with 335 pages with one page Errata. Pages in beautiful condition with only a few marks. Binding shows age-consistent wear to boards, mild warping of boards. Vol. I front hinge starting at base, small hole in leather at base of spine. Very good overall. Uncommon. Arguably Condillac's most important work (important as well in the context of his peers in French and European Philosophy), it is also his most widely known title. Here he presents the "Sentient Statue" to demonstrate that human experience can be summed solely of sensations. Additional photos or more detailed condition reports available upon request.
