The first is from the English translation of Ludwig Lachmann’s 1966 essay “The Significance of the Austrian School of Economics in the History of Ideas ,” which appears on pages 45-64 of Ludwig M. Lachmann, Capital, Expectations, and the Market Process , Walter E. Grinder, ed. (1977); the quotation is from page 46 (original emphasis):

The second quotation is from page 15 of Brian Loasby’s fine 1976 book, Choice, Complexity and Ignorance :
