a. I will now indicate more fully the main features, in so far as they possess philosophic interest. Though Plato represents what the state is in its truth, yet this state has a limit, which we shall learn to know, namely, that the individual—in formal justice—is not opposed to this universality, as in the dead constitution of the ideal states founded on the theory of legal right. The content is but the whole; the nature of the individual, no doubt, but as reflecting itself into the universal, not unbending, or as having absolute validity; so that practically the state and the individual are the same in essence. Because Plato thus takes his start from that justice which implies that the just man exists only as a moral member of the state, in dealing with his subject in greater detail, in order to show how this reality of the substantial mind is produced, he in the first place opens up before us the organism of the moral commonwealth, _i.e._ the differences which lie in the Notion of moral substance. Through the development of these moments it becomes living and existing, but these moments are not independent, for they are held in unity. Plato regards these moments of the moral organism under three aspects, first, as they exist in the state as classes; secondly, as virtues, or moments in morality; thirdly, as moments of the individual subject, in the empirical actions of the will. Plato does not preach the morality of reflection, he shows how traditional morality has a living movement in itself; he demonstrates its functions, its inward organism. For it is inner systematization, as in organic life, and not solid, dead unity, like that of metals, which comes to pass by means of the different functions of the organs which go to make up this living, self-moving unity.
α. Without classes, without this division into great masses, the state has no organism; these great distinctions are the distinction of the substantial. The opposition which first comes before us in the state is that of the universal, in the form of state life and business, and the individual, as life and work for the individual; these two fields of activity are so distinct that one class is assigned to the one, and another to the other. Plato further cites three systems of reality in the moral, the functions (αα) of legislation, counsel, in short, of diligence and foresight in the general behalf, in the interest of the whole as such; (ββ) of defence of the commonwealth against foes from without; (γγ) of care for the individual, the supplying of wants, agriculture, cattle-rearing, the manufacture of clothing and utensils, the building of houses, &c. Speaking generally, this is quite as it should be, and yet it appears to be rather the satisfaction of external necessities, because such wants are found without being developed out of the Idea of mind itself. Further, these distinct functions are allotted to different systems, being assigned to a certain number of individuals specially set apart for the purpose, and this brings about the separate classes of the state, as Plato is altogether opposed to the superficial conception that one and the same must be everything at one time. He accordingly represents three classes, (αα) that of the governors, men of learning and wisdom, (ββ) that of the warriors, (γγ) that of the producers of necessaries, the husbandmen and handicraftsmen. The first he also speaks of as guardians (φύλακας), who are really philosophically educated statesmen, possessing true knowledge; they have the warriors to work on their behalf (ἐπικούρους τε καὶ βοηθούς), but in such a way that there is no line of separation between the civil and military classes, both being united,[61] and the most advanced in years are the guardians.[62] Although Plato does not deduce this division of the classes, they follow from the constitution of the Platonic state, and every state is necessarily a system within itself of these systems. Plato then passes on to particular determinations, which are in some measure trifling, and might with advantage have been dispensed with; for instance, among other things, he goes so far as to settle for the highest rank their special titles, and he states what should be the duties of the nurses.[63]
