The Rulers and their auxiliaries the body of Guardians must be lodged in residences, sufficient for shelter and comfort, yet suitable for military men, and not for tradesmen. Every arrangement must be made for rendering them faithful guardians of the remaining citizens. It would be awful indeed, if they were to employ their superior strength in oppressing instead of protecting the flock entrusted to them. To ensure their gentleness and fidelity, the most essential guarantee is to be found in the good musical and gymnastic training which they will have received. But this alone will not suffice. All the conditions of their lives must be so determined, that they shall have the least possible motive for committing injustice towards the other citizens. None of them must have any separate property of his own, unless in special case of proved necessity: nor any house or store cupboard from which others are excluded. They must receive, from the contributions of the remaining citizens, sufficient subsistence for the health and comfort of military men, but nothing beyond. They must live together in their camp or barrack, and dine together at a public mess-table. They must not be allowed either to possess gold and silver, or to drink in cups of those metals, or to wear them as appendages to clothing, or even to have them under the same roof. They must be told, that these metals, though not forbidden to the other citizens, are forbidden to them, because they have permanently inherent in their mental constitution the divine gold and silver, which would be corrupted by intermixture with human.[86] [Footnote 86: Plato, Republic, iii. pp. 416-417.] [Side-note: If the Guardians fail in these precautions, and acquire private interests, the city will be ruined.] If these precautions be maintained, the Guardians may be secure themselves, and may uphold in security the entire city. But if the precautions be relinquished--if the Guardians or Soldiers acquire separate property in lands, houses, and money--they will then become householders and husbandmen instead of Guardians or Soldiers: hostile masters, instead of allies and protectors to their fellow-citizens. They will hate their fellow-citizens, and be hated by them in return: they will conspire against them, and will be themselves conspired against. In this manner they will pass their lives, dreading their enemies within far more than their enemies without. They, and the whole city along with them, will be perpetually on the brink of destruction.[87] [Footnote 87: Plato, Republic, iii. p. 417 A-B.] [Side-note: Complete unity of the city, every man performing his own special function.]
