At what point a history of socialism should begin is a question which might give occasion to high argument.
There are some who hold that we merely becloud our judgment if we allow ourselves to speak of socialism before the middle of the 18th century, or perhaps even somewhat later. On this view socialism is essentially a manifestation of the proletarian spirit; or, if socialism is not necessarily proletarian in character and origin, it at least postulates a society which tends to be comprehensive in its membership. Accordingly, it is suggested that a society which assumes for its efficient working the existence of a slave population, denied all rights, may at times speak a language suggestive of socialism, but it can know nothing of socialism as that word has been understood in the 19th and 20th centuries. The existence of a serf or slave population may in certain respects add a complication to life; but in other directions it quite obviously enormously simplifies the social and political problems of existence, as these are presented to that section of the population who are not slaves. On this view, a history of socialism should probably begin among these first ripples and disturbances which presaged the deluge of the French Revolution.
As against this view, which looks on socialism as something which cannot be dissociated from the social and political conditions of the last century and a half, there are some who carry their excavations for the roots of socialism not merely to ancient Greece, but to ancient China and to the early days of the children of Israel, and who accord a place in the socialist temple to Moses, in virtue of certain provisions in the Mosaic Law; and to Isaiah, in virtue of his poetic sensitiveness to the wrongs of this world.
If we are strict, it is probably to the former of these views that we should incline. We shall see presently how futile to our present-day mind is the justice and the equality of a state which attains these elevated aims by building on the slavery and oppression of the overwhelming majority of the population. Yet it does not follow that the history of socialism can exclude all that happened before the 18th century. Lycurgus and the polity of Sparta may in fact have little to teach us. The community of life which Minos introduced into Crete may have no point of contact with our modern needs. Plato, to ascend to higher names, may have dreamed a dream which would be but a nightmare today, if any attempt were made to realize it. Yet throughout the ages, somewhat surprisingly, the limitations imposed by the assumptions of Sparta and Athens have been overlooked. Plato and Lycurgus, to mention no others, have been permanent influences in molding communist theory. This is particularly true of Plato, though at times (as in Mably) Lycurgus runs him hard. It would be an unpardonable exaggeration to say that all communism and egalitarianism derive from Plato; but on the more visionary and Utopian side, he is everywhere. Like the fabled tree of the nursery, his evergreen branches have given support and shelter to all manner of strange birds, great and small: Tous les oiseaux du monde vont y faire leurs nids.
Even if the "socialism" of antiquity has, in its own right, no claim to be considered as an integral element in a history of socialism, its representatives demand attention as inspirers of socialism in others in much later centuries.
This subsequent appeal to Greece, as the presumed holder of the original title-deeds of socialism, has been made on two grounds. On the one hand, Greece, in its highly variegated political life, is presumed to have given examples of the actual functioning of the communistic way of life. Here, of course, it is pre-eminently Sparta that has fascinated later ages; though Crete also enters into the picture — and to a much lesser extent, Lipara. On the other hand, Greece has supplied the theory and the vision of Communism. On this side, needless to say, it is Plato, in The Republic and The Laws, who in himself very largely constitutes the legacy of Greece. Before approaching Plato, the begetter of much socialism which he would have disowned, it may be advisable to glance, even if hastily, at Greek communism in practice. More> Ancient Spartan Communism
