“ Now the most striking characteristic of man, that in fact which marks him specially, as contrasted with other animals, is self-consciousness. The simplest mental act into which we can analyse the operations of the human mind—the act of sense-perception—is never merely a change, physical or psychical, but is the consciousness of a change. Human experience consists, not of processes in an animal organism, but of these processes recognized as such. ”
