Vagueness and Bayesian probability

This paper is a response to Michael Laviolette and John W. Seaman Jr.´s ( ibid. vol.2, no.1, p.4 (1994)) position paper “The efficacy of fuzzy representations of uncertainty,” which criticizes fuzzy representations of uncertainty, and suggests that Bayesian probability can do better. The commenter argues that the author´s make some misleading comments about Bayesian probability, and he briefly discusses the problem of giving a satisfactory interpretation of membership functions
