In a less-cited passage, Planck gives a slightly different formulation to his principle: “An important scientific innovation rarely makes its way by gradually winning over and converting its opponents: it rarely happens that Saul becomes Paul. What does happen is that its opponents die out and that the growing generation is familiarized with the idea from the beginning: another instance of the fact that the future lies with youth” (The Philosophy of Physics [New York, 1936], p. 97Google Scholar).

⁸ Our paper appeared in Science, 202 (Nov. 17, 1978), 717–23. In an unpublished, econometrically sophisticated examination of the acceptance of the wage-push theory of inflation, David Levy of the National Planning Association reports results that disconfirm Planck's Principle (“What Was Classical Monetary Theory?” [mimeo. draft, Feb. 19, 1980], pp. 30–32). I attempted another test by using marginal utility theory, drawing my sample from a list of acceptors of marginal utility compiled by Stigler, George, “The Adoption of the Marginal Utility Theory” (in The Marginal Revolution in Economics, ed. Black, R. D. Collison, et al. [Durham, NC, 1973], p. 312)Google Scholar. The test was of questionable value, however, because of difficulty in pinpointing the year of acceptance, small sample size, and an inappropriate age range (from 4 to 34) for acceptors at the time of the invention of marginal utility (1871). See Diamond, “Science as a Rational Enterprise,” pp. 124–29.
