Note 9 — THE COURS DE PHILOSOPHIE POSITIVE.

Those who wish to see this idea followed out, are referred to "A System of Logic, Ratiocinative and Inductive." It is not irrelevant to state that M. Comte, soon after the publication of that work, expressed, both in a letter (published in M. Littré's volume) and in print, his high approval of it (especially of the Inductive part) as a real contribution to the construction of the Positive Method. But we cannot discover that he was indebted to it for a single idea, or that it influenced, in the smallest particular, the course of his subsequent speculations.
