The same view is reflected in the speculations of political philosophers. Plato, indeed, in his Republic, goes so far as to eliminate the family relation altogether. Not only is the whole connection between men and women to be regulated by the State, in respect both of the persons and of the limit of age within which they may associate, but the children as soon as they are born are to be carried off to a common nursery, there to be reared together, undistinguished by the mothers, who will suckle indifferently any infant that might happen to be assigned to them for the purpose. Here, as in other instances, Plato goes far beyond the limits set by the current sentiment of the Greeks, and in his later work is reluctantly constrained to abandon his scheme of community of wives and children. Yet even there he makes it compulsory on every man to marry between the ages of thirty and thirty-five, under penalty of fine and civil disabilities. Plato, no doubt, as we have said, exaggerates the opinions of his time; but the view, which he pushes to its extreme, of the subordination of the family to the State, was one, as we have already pointed out, which did predominate in Greece. It reappears in a soberer form in the treatise of Aristotle. He too would regulate by law both the age at which marriages should take place and the number of children that should be produced, and would have all deformed infants exposed. And here, no doubt, he is speaking in conformity if not with the practice, at least with the feeling of Greece. The modern conception that the marriage relation is a matter of private concern, and that any individual has a right to wed whom and when he will, and to produce children at his own discretion, regardless of all considerations of health and decency, was one altogether alien to the Greeks. In theory at least, and to some extent in practice (as for example in the case of Sparta), they recognised that the production of children was a business of supreme import to the State, and that it was right and proper that it should be regulated by law with a view to the advantage of the whole community. * * * * *
