On the Method of Theoretical Physics. The Herbert Spencer Lecture. Delivered at Oxford, 10 June 1933. EINSTEIN, Albert.

First edition of this account of Einstein's scientific philosophy and methodology, in which he discusses the tension between empirical experimentation and theoretical reasoning. It was republished the following year in Mein Weltbild. The title page has a Clarendon Press "Revise" stamp, dated 10 June 1933; the ink correction to the text on page 13 is presumably to be implemented in the next printing. Boni 219; Weil 188. Duodecimo (172 x 113 mm), pp. 16. Recent pale blue card wrappers. A very good copy.
