London: Hutchinson. 1959. 8vo. Publisher's grey cloth with gilt red lettering-piece to spine, top-edge stained red, pale green endpapers, publisher's dust-jacket printed in red with printed price of 50s to front flap; pp. 479, [1]; spine of jacket sunned, slight discolouration and spotting to rear cover; slight spotting to fore-edge of textblock; otherwise near fine.

He also argues that the only true knowledge is scientific, empirical truth. Popper's belief that human knowledge is fallible would later extend beyond science and into the political realm. The principles expounded in this book led him to criticise many, including Marxists, for continuing to follow an empirical theory that had failed in practice (The Poverty of Historicism, 1944).
