[Postscript to the Logic of Scientific Discovery. Comprising:] Realism and the Aim of Science (Volume 1); The Open Universe (Volume 2); Quantum Theory and the Schism in Physics (Volume 3). by POPPER, Karl R - 1982–3

London: Hutchinson,, 1982–3. Edited by W. W. Bartley, III. 3 works, octavo. Original black cloth, titles to spine gilt. With the dust jackets. An excellent set in bright jackets with occasional minor nicks; original price stickers to front flaps of two volumes; small tape repair to verso of spine panel of Realism and the Aim of Science. First editions in book form, first impressions, of one of the major works on determinism and indeterminism, Popper's three-part postscript to his first published book, The Logic of Scientific Discovery (1936). Although the culmination of Popper's work in the philosophy of physics (reaching its peak in the second volume, The Open Universe) the Postscript took almost three decades to be published. Originally intended as appendices to a later edition of The Logic of Scientific Discovery, the three works grew into a fully-fledged work which actually exceeded in length The Logic of Scientific Discovery. In 1956–7 The Postscript was all set to be published and already existed in the form of galley proofs but because of his deteriorating eyesight Popper was never able to proof-read the galleys and the whole project remained on hold for 25 years.
