The "social problem," then, had clearly arisen in ancient Greece, though no doubt in an infinitely simpler form than that in which it is presented to ourselves; and it might perhaps have been expected that the Greeks, with their notion of the supremacy of the state, would have adopted some drastic public measure to meet it. And, in fact, in the earlier period of their history, as has been indicated above, we do find sweeping revolutions effected in the distribution of property. In Athens, Solon abolished debt, either in whole or part, by reducing the rate of interest and depreciating the currency; and in Sparta Lycurgus is said to have resumed the whole of the land for the state, and redivided it equally among the citizens. We have also traces of laws existing in other states to regulate in the interests of equality the possession and transfer of land. But it does not appear that any attempt was made in any state permanently to control by public authority the production and distribution of wealth. Meantime, however, the problem of social inequality was exercising the minds of political theorists; and we have notice of various schemes for an ideal polity framed upon communistic principles. Of these the most important, and the only one preserved to us, is the celebrated "Republic" of Plato; and never, it may be safely asserted, was a plan of society framed so consistent, harmonious and beautiful in itself, or so indifferent to the actual capacities of mankind. Following out what we have already indicated as the natural drift of Greek ideas, the philosopher separates off on the one hand the productive class, who are to have no political rights; and on the other the class of soldiers and governors. It is the latter alone with whom he seriously concerns himself; and the scheme he draws up for them is uncompromisingly communistic. After being purged, by an elaborate education, of all the egoistic passions, they are to live together, having all things in common, devoted heart and soul to the public good, and guiltless even of a desire for any private possession or advantage of their own. "In the first place, no one," says Plato, "should possess any private property, if it can possibly be avoided; secondly, no one should have a dwelling or store house into which all who please may not enter; whatever necessaries are required by temperate and courageous men, who are trained to war, they should receive by regular appointment from their fellow-citizens, as wages for their services, and the amount should be such as to leave neither a surplus on the year's consumption nor a deficit; and they should attend common messes and live together as men do in a camp: as for gold and silver, we must tell them that they are in perpetual possession of a divine species of the precious metals placed in their souls by the gods themselves, and therefore have no need of the earthly one; that in fact it would be
