ABSTRACT
Bridgman, Percy . . . the most striking thing about cosmogony is the perfectly hair raising extrapolations which it is necessary to make. We have to extend the times of the order of 1013 years and distances of the order of 109 light years laws which have been checked in a range of not more than 3 102 years, and certainly in distances not greater than the distance which the solar system has traveled in that time, or about 4 102 light years. It seems to me that one cannot take such extrapolations seriously unless one subscribes to a metaphysics that claims that laws of the necessary mathematical precision really control the actual physical universe.
