Perception is a fact of mixed nature, at once physiological and mental; it is begun in the organs, is perfected in the consciousness. The soundness of the common opinion which regards our sensations as simple, irreducible, ultimate phenomena, by means of which we know the material world as it is, is extremely doubtful. Setting aside the discussion of this broad question, it is only necessary to say that, taking for their basis physical and physiological discoveries, recent works on psychology--notably those of Bain and Herbert Spencer in England, of Helmholtz and Wundt in Germany, and of Taine in France--have shown that sensations supposed to be simple must be dealt with, as chemistry, at its rise, dealt with bodies, also supposed to be simple. These psychologists have shown that neither colours, nor sounds, nor heat, probably, indeed, none of the qualities of the external world, at all resemble the ideas vulgarly entertained with regard to them; that perception is a state of consciousness that corresponds in us to realities external to ourselves, but which does not resemble them: so that this totality of attributes which we call the external world, and which, by a universal illusion, we think we see as it is in reality, is to a great extent the product of our own mind--a creation of which the external world furnishes only the raw material, which our senses then, after their own fashion, work up and complete.
