One school of thought attributes Calvinism with setting the stage for the later development of capitalism in northern Europe. In this view, elements of Calvinism represented a revolt against the medieval condemnation of usury and, implicitly, of profit in general.[citation needed] Such a connection was advanced in influential works by R. H. Tawney (1880–1962) and by Max Weber (1864–1920). Calvin expressed himself on usury in a 1545 letter to a friend, Claude de Sachin, in which he criticized the use of certain passages of scripture invoked by people opposed to the charging of interest. He reinterpreted some of these passages, and suggested that others of them had been rendered irrelevant by changed conditions. He also dismissed the argument (based upon the writings of Aristotle) that it is wrong to charge interest for money because money itself is barren. He said that the walls and the roof of a house are barren, too, but it is permissible to charge someone for allowing him to use them. In the same way, money can be made fruitful.[136] He qualified his view, however, by saying that money should be lent to people in dire need without hope of interest, while a modest interest rate of 5% should be permitted in relation to other borrowers.
