We hardly appreciate the power which the idea of the State, like all other abstract ideas, exercised over the mind of Plato. To us the State seems to be built up out of the family, or sometimes to be the framework in which family and social life is contained. But to Plato in his present mood of mind the family is only a disturbing influence which, instead of filling up, tends to disarrange the higher unity of the State. No organization is needed except a political, which, regarded from another point of view, is a military one. The State is all-sufficing for the wants of man, and, like the idea of the Church in later ages, absorbs all other desires and affections. In time of war the thousand citizens are to stand like a rampart impregnable against the world or the Persian host; in time of peace the preparation for war and their duties to the State, which are also their duties to one another, take up their whole life and time. The only other interest which is allowed to them besides that of war, is the interest of philosophy. When they are too old to be soldiers they are to retire from active life and to have a second novitiate of study and contemplation. There is an element of monasticism even in Plato’s communism. If he could have done without children, he might have converted his Republic into a religious order. Neither in the Laws, when the daylight of common sense breaks in upon him, does he retract his error. In the state of which he would be the founder, there is no marrying or giving in marriage: but because of the infirmity of mankind, he condescends to allow the law of nature to prevail.
