We have already dealt generally from the theoretical side with the speculative nature of mind as yet unrealized, as well as with the highly important differences with respect to the kinds of knowledge (pp. 28-48). It must also be considered that we find in Plato as yet no developed consciousness of the organization of the theoretic mind, though certainly sensation, memory, &c., are distinguished by him from reason; these moments of the mind are, however, neither accurately discriminated, nor exhibited in their connection, so as to show the necessary relations between them. The only point of interest for us then in Plato’s philosophy of mind is his view of man’s moral nature; and this real, practical side of consciousness is Plato’s greatest glory, and hence must now be specially dealt with by us. Its form certainly does not suggest that Plato gave himself much trouble to discover a supreme moral principle, as it is now called, which, for the very reason that it is supposed to be all-embracing, has in it a certain lack of content. Neither did he trouble himself about a natural right, which is but a trivial abstraction foisted on to the real practical existence, the right; but it is of man’s moral nature that he treats in the Republic. Man’s moral nature seems to us to have little to do with the State; to Plato, however, the reality of mind—that is, of mind as opposed to nature—appeared in its highest truth as the organization of a state which, as such, is essentially moral; and he recognized that the moral nature (free will in its rationality) comes to its right, to its reality, only in an actual nation.
