Moreover, my system, save in the mocking literary sense of the word, is not metaphysical. It contains much criticism of metaphysics, and some refinements in speculation, like the doctrine of essence, which are not familiar to the public; and I do not disclaim being metaphysical because I at all dislike dialectic or disdain immaterial things: indeed, it is of immaterial things, essence, truth, and spirit that I speak chiefly. But logic and mathematics and literary psychology (when frankly literary) are not metaphysical, although their subject-matter is immaterial, and their application to existing things is often questionable.

Speculations about the natural world, such as those of the Ionian philosophers, are not metaphysics, but simply cosmology or natural philosophy. Now in natural philosophy I am a decided materialist — apparently the only one living; and I am well aware that idealists are fond of calling materialism, too, metaphysics, in rather an angry tone, so as to cast discredit upon it by assimilating it to their own systems. But my materialism, for all that, is not metaphysical. I do not profess to know what matter is in itself, and feel no confidence in the divination of those esprits forts who, leading a life of vice, thought the universe must be composed of nothing but dice
