The citizens, as in other Hellenic States, democratic as well as aristocratic, are really an upper class; for, although no mention is made of slaves, the lower classes are allowed to fade away into the distance, and are represented in the individual by the passions. Plato has no idea either of a social State in which all classes are harmonized, or of a federation of Hellas or the world in which different nations or States have a place. His city is equipped for war rather than for peace, and this would seem to be justified by the ordinary condition of Hellenic States. The myth of the earth-born men is an embodiment of the orthodox tradition of Hellas, and the allusion to the four ages of the world is also sanctioned by the authority of Hesiod and the poets. Thus we see that the Republic is partly founded on the ideal of the old Greek polis, partly on the actual circumstances of Hellas in that age. Plato, like the old painters, retains the traditional form, and like them he has also a vision of a city in the clouds.

      There is yet another thread which is interwoven in the texture of the work; for the Republic is not only a Dorian State, but a Pythagorean league. The ‘way of life’ which was connected with the name of Pythagoras, like the Catholic monastic orders, showed the power which the mind of an individual might exercise over his contemporaries, and may have naturally suggested to Plato the possibility of reviving such ‘mediaeval institutions.’ The Pythagoreans, like Plato, enforced a rule of life and a moral and intellectual training. The influence ascribed to music, which to us seems exaggerated, is also a Pythagorean feature; it is not to be regarded as representing the real influence of music in the Greek world. More nearly than any other government of Hellas, the Pythagorean league of three hundred was an aristocracy of virtue. For once in the history of mankind the philosophy of order or (Greek), expressing and consequently enlisting on its side the combined endeavours of the better part of the people, obtained the management of public affairs and held possession of it for a considerable time (until about B.C. 500). Probably only in States prepared by Dorian institutions would such a league have been possible. The rulers, like Plato’s (Greek), were required to submit to a severe training in order to prepare the way for the education of the other members of the community. Long after the dissolution of the Order, eminent Pythagoreans, such as Archytas of Tarentum, retained their political influence over the cities of Magna Graecia. There was much here that was suggestive to the kindred spirit of Plato, who had doubtless meditated deeply on the ‘way of life of Pythagoras’ (Rep.) and his followers. Slight traces of Pythagoreanism are to be found in the mystical number of the State, in the number which expresses the interval between the king and the tyrant, in the doctrine of transmigration, in the music of the spheres, as well as in the great though secondary importance ascribed to mathematics in education.

      But as in his philosophy, so also in the form of his State, he goes far beyond the old Pythagoreans. He attempts a task really impossible, which is to unite the past of Greek history with the future of philosophy, analogous to that other impossibility, which has often been the dream of Christendom, the attempt to unite the past history of Europe with the kingdom of Christ. Nothing actually existing in the world at all resembles Plato’s ideal State; nor does he himself imagine that such a State is possible. This he repeats again and again; e.g. in the Republic, or in the Laws where, casting a glance back on the Republic, he admits that the perfect state of communism and philosophy was impossible in his own age, though still to be retained as a pattern. The same doubt is implied in the earnestness with which he argues in the Republic that ideals are none the worse because they cannot be realized in fact, and in the chorus of laughter, which like a breaking wave will, as he anticipates, greet the mention of his proposals; though like other writers of fiction, he uses all his art to give reality to his inventions. When asked how the ideal polity can come into being, he answers ironically, ‘When one son of a king becomes a philosopher’; he designates the fiction of the earth-born men as ‘a noble lie’; and when the structure is finally complete, he fairly tells you that his Republic is a vision only, which in some sense may have reality, but not in the vulgar one of a reign of philosophers upon earth. It has been said that Plato flies as well as walks, but this falls short of the truth; for he flies and walks at the same time, and is in the air and on firm ground in successive instants.

      Niebuhr has asked a trifling question, which may be briefly noticed in this place — Was Plato a good citizen? If by this is meant, Was he loyal to Athenian institutions? — he can hardly be said to be the friend of democracy: but neither is he the friend of any other existing form of government; all of them he regarded as ‘states of faction’ (Laws); none attained to his ideal of a voluntary rule over voluntary subjects, which seems indeed more nearly to describe democracy than any other; and the worst of them is tyranny. The truth is, that the question has hardly any meaning when applied to a great philosopher whose writings are not meant for a particular age and country, but for all time and all mankind. The decline of Athenian politics was probably the motive which led Plato to frame an ideal State, and the Republic may be regarded as reflecting the departing glory of Hellas. As well might we complain of St. Augustine, whose great work ‘The City of God’ originated in a similar motive, for not being loyal to the Roman Empire. Even a nearer parallel might be afforded by the first Christians, who cannot fairly be charged with being bad citizens because, though ‘subject to the higher powers,’ they were looking forward to a city which is in heaven.

      2. The idea of the perfect State is full of paradox when judged of according to the ordinary notions of mankind. The paradoxes of one age have been said to become the commonplaces of the next; but the paradoxes of Plato are at least as paradoxical to us as they were to his contemporaries. The modern world has either sneered at them as absurd, or denounced them as unnatural and immoral; men have been pleased to find in Aristotle’s criticisms of them the anticipation of their own good sense. The wealthy and cultivated classes have disliked and also dreaded them; they have pointed with satisfaction to the failure of efforts to realize them in practice. Yet since they are the thoughts of one of the greatest of human intelligences, and of one who had done most to elevate morality and religion, they seem to deserve a better treatment at our hands. We may have to address the public, as Plato does poetry, and assure them that we mean no harm to existing institutions. There are serious errors which have a side of truth and which therefore may fairly demand a careful consideration: there are truths mixed with error of which we may indeed say, ‘The half is better than the whole.’ Yet ‘the half’ may be an important contribution to the study of human nature.

      (a) The first paradox is the community of goods, which is mentioned slightly at the end of the third Book, and seemingly, as Aristotle observes, is confined to the guardians; at least no mention is made of the other classes. But the omission is not of any real significance, and probably arises out of the plan of the work, which prevents the writer from entering into details.

      Aristotle censures the community of property much in the spirit of modern political economy, as tending to repress industry, and as doing away with the spirit of benevolence. Modern writers almost refuse to consider the subject, which is supposed to have been long ago settled by the common opinion of mankind. But it must be remembered that the sacredness of property is a notion far more fixed in modern than in ancient times. The world has grown older, and is therefore more conservative. Primitive society offered many examples of land held in common, either by a tribe or by a township, and such may probably have been the original form of landed tenure. Ancient legislators had invented various modes of dividing and preserving the divisions of land among the citizens; according to Aristotle there were nations who held the land in common and divided the produce, and there were others who divided the land and stored the produce in common. The evils of debt and the inequality of property were far greater in ancient than in modern times, and the accidents to which property was subject from war, or revolution, or taxation, or other legislative interference, were also greater. All these circumstances gave property a less fixed and sacred character. The early Christians are believed to have held their property in common, and the principle is sanctioned by the words of Christ himself, and has been maintained as a counsel of perfection in almost all ages of the Church. Nor have there been wanting instances of modern enthusiasts who have made a religion of communism; in every age of religious excitement notions like Wycliffe’s ‘inheritance of grace’ have tended to prevail. A like spirit, but fiercer and more violent, has appeared in politics. ‘The preparation of the Gospel of peace’ soon becomes the red flag of Republicanism.

      We can hardly judge
