Then now let us consider what will be their way of life, if they are to realize our idea of them. In the first place, none of them should have any property of his own beyond what is absolutely necessary; neither should they have a private house or store closed against any one who has a mind to enter; their provisions should be only such as are required by trained warriors, who are men of temperance and courage; they should agree to receive from the citizens a fixed rate of pay, enough to meet the expenses of the year and no more; and they will go to mess and live together like soldiers in a camp. Gold and silver we will tell them that they have from God; the diviner metal is within them, and they have therefore no need of the dross which is current among men, and ought not to pollute the divine by any such earthly admixture; for that commoner metal has been the source of many unholy deeds, but their own is undefiled. And they alone of all the citizens may not touch or handle silver or gold, or be under the same roof with them, or wear them, or drink from them. And this will be their salvation, and they will be the saviours of the State.
But should they ever acquire homes or lands or moneys of their own, they will become housekeepers and husbandmen instead of guardians, enemies and tyrants instead of allies of the other citizens; hating and being hated, plotting and being plotted against, they will pass their whole life in much greater terror of internal than of external enemies, and the hour of ruin, both to themselves and to the rest of the State, will be at hand. For all which reasons may we not say that thus shall our State be ordered, and that these shall be the regulations appointed by us for guardians concerning their houses and all other matters?
—Plato in The Republic
And there is another objection to the proposal. For that which is common to the greatest number has the least care bestowed upon it. Every one thinks chiefly of his own, hardly at all of the common interest; and only when he is himself concerned as an individual. For besides other considerations, everybody is more inclined to neglect the duty which he expects another to fulfill; as in families many attendants are often less useful than a few

Next let us consider what should be our arrangements about property: should the citizens of the perfect state have their possessions in common or not?...when they till the ground for themselves the question of ownership will give a world of trouble. If they do not share equally enjoyments and toils, those who labor much and get little will necessarily complain of those who labor little and receive or consume much…
…how immeasurably greater is the pleasure, when a man feels a thing to be his own; for surely the love of self is a feeling implanted by nature and not given in vain, although selfishness is rightly censured; this, however, is not the mere love of self, but the love of self in excess, like the miser’s love of money; for all, or almost all, men love money and other such objects in a measure…
…And further, there is the greatest pleasure in doing a kindness or service to friends or guests or companions, which can only be rendered when a man has private property.
—Aristotle in Politics
