"There are many points upon which Comte and Buckle are one; perhaps they are even more than those in which they differ: but while the former are mostly subsidiary, the latter are mostly fundamental. Comte's laws of civilization are evolved as a necessary deduction... Buckle... proves the predictability of human actions by statistics. ...Buckle ...discovers the laws of civilization first inductively, and then ...reverses the process and proves them deductively. ...Every step Buckle takes is strictly reasoned, and his proof is more positive and verified than any Comte chooses ...Buckle's work stands on the same basis as any other scientific work, while Comte with all his positive claim ...[has] no inductive complement to his deductive proof."
