The Guardians, of both sexes, thus educated and disciplined, are intended to pass their whole lives in the discharge of their duties as Guardians; implicitly obeying the orders of the Few Philosophical chiefs, and quartered in barracks under strict regulations. Among these regulations, there are two in particular which have always provoked more surprise and comment than any other features in the commonwealth; first, the prohibition of separate property--next, the prohibition of separate family--including the respective position of the two sexes. [Side-note: Purpose of Plato in these regulations.] The directions of Plato on these two points not only hang together, but are founded on the same reason and considerations. He is resolved to prevent the growth of any separate interest, affections, or aspirations, in the mind of any individual Guardian. Each Guardian is to perform his military and civil duties to the Commonwealth, and to do nothing else. He must find his happiness in the performance of his duty: no double functions or occupations are tolerated. This principle, important in Plato's view as regards every one, is of supreme importance as applying to the Guardians,[93] in whom resides the whole armed force of the Commonwealth and by whom the orders of the Chiefs or Elders are enforced. If the Guardians aspire to private ends of their own, and employ their force for the attainment of such ends, nothing but oppression and ruin of the remaining community can ensue. A man having land of his own to cultivate, or a wife and family of his own to provide with comforts, may be a good economist, but he will never be a tolerable Guardian.[94] To be competent for this latter function, he must neither covet wealth nor be exposed to the fear of poverty: he must desire neither enjoyments nor power, except what are common to his entire regiment. He must indulge neither private sympathies nor private antipathies: he must be inaccessible to all motives which could lead him to despoil or hurt his fellow-citizens the producers. Accordingly the hopes and fears involved in self-maintenance--the feelings of buyer, seller, donor, or receiver--the ideas of separate property, house, wife, or family--must never be allowed to enter into his mind. The Guardians will receive from the productive part of the community a constant provision, sufficient, but not more than sufficient, for their reasonable maintenance. Their residence will be in public barracks and their meals at a common mess: they must be taught to regard it as a disgrace to meddle in any way with gold and silver.[95] Men and women will live all together, or distributed in a few fractional companies, but always in companionship, and under perpetual drill; beginning from the earliest years with both sexes. Boys and girls will be placed from the beginning under the same superintendence; and will receive the same training, as well in gymnastic as in music.
