Hence it is led to consider even the perceived qualities of matter,—sensible, and consequently felt, qualities,—as so many phosphorescences which follow the track of the cerebral phenomena in the act of perception. Matter, thus supposed capable of creating elementary facts of consciousness, might therefore just as well engender intellectual facts of the highest order. It is, then, of the essence of materialism to assert the perfect relativity of sensible qualities, and it is not without good reason that this thesis, which Democritus has formulated in precise terms, is as old as materialism.

Matter has thus too often been reduced to a mysterious entity which, just because all we
