The method of Austrian economics stresses the use of words and concepts rather than mathematics, but, unlike mathematics, words and concepts change their meaning through time. That f '(x) < 0 implies a negatively sloping curve was as clear. to Newton as it is to a modern mathematical economist. The meaning Carl Menger ascribed to the term utility, however, differed from that of Mises. Furthermore, the meaning of words in one context can infuse and distort the meaning in another context. This is why, as Austrian economists, we must occasionally "clean house," re-examine our concepts, and clarify any that have become distorted.
