Abstract

After a discussion of Bacon's views on the subject, Van Leeuwen examines a different theory of certainty. This is the theory that was elaborated by Chillingworth and Tillotson, two English Protestant clergymen, in the course of a controversy centering upon the problem of deciding with certainty which beliefs constituted a Rule of Faith, i.e., the basic requirements of belief for Salvation. Chillingworth and Tillotson attempted to avoid both dogmatism and total skepticism by insisting on the existence of levels of certainty and maintaining that the criteria of common sense are appropriate for the solution of theoretical religious questions. According to Van Leeuwen, the application of this theory is extended to scientific contexts in the work of Wilkins and Glanvill and is inherent in the scientific work of such members of the Royal Society as Boyle and Newton. The exposition is good; but the author's claim to a rigorous evolutionary line in the development of the doctrine of certainty among the figures he has treated is sometimes overstated.—T. J. C.
