Schumpeter's style ran not only to frequent digressions, which I have tried to eliminate, but also to surplus words, to stating what is already implied, to burdening the reader with phrases that distract his attention. In such a sentence as, "It is surely not too much to ask economists to realize that behavior in human societies differs from behavior in animal societies or in physical systems" (p. 1046 of the 1939 edition), I have deleted the italicized words without using dots to so indicate. Occasionally it was convenient to alter the punctuation. I have generally resisted the temptation to substitute.
