There is much of economic theory which is pursued for no better reason than its intellectual attraction; it is a good game. We have no reason to be ashamed of that, since the same would hold for many branches of mathematics.
Sir John Richard Hicks (April 8, 1904 May 20, 1989) was one of the most important and influential economists of the twentieth century. Hicks was born in Leamington Spa in Warwickshire, England, and was educated at Clifton College and Balliol College, Oxford. Subsequently he became a lecturer at the LSE where he met Friedrich Hayek. He spent the years from 1935 to 1938 at the University of Cambridge, mainly occupied with writing on his book Value and Capital. From 1938 to 1946 Hicks was a Professor at the Victoria University of Manchester. In 1946 he returned to Oxford, first being a research fellow of Nuffield College (1946-1965), then becoming Drummond Professor of Political Economics (1952-1965), and, after that, research fellow of All Souls College (1965-1971).
