It must be reiterated that our reasoning still leaves Utopian marriage an institution with wide possibilities of variation. We have tried to give effect to the ideal of a virtual equality, an equality of spirit between men and women, and in doing so we have overridden the accepted opinion of the great majority of mankind. Probably the first writer to do as much was Plato. His argument in support of this innovation upon natural human feeling was thin enough--a mere analogy to illustrate the spirit of his propositions; it was his creative instinct that determined him. In the atmosphere of such speculations as this, Plato looms very large indeed, and in view of what we owe to him, it seems reasonable that we should hesitate before dismissing as a thing prohibited and evil, a type of marriage that he made almost the central feature in the organisation of the ruling class, at least, of his ideal State. He was persuaded that the narrow monogamic family is apt to become illiberal and anti-social, to withdraw the imagination and energies of the citizen from the services of the community as a whole, and the Roman Catholic Church has so far endorsed and substantiated his opinion as to forbid family relations to its priests and significant servants. He conceived of a poetic devotion to the public idea, a devotion of which the mind of Aristotle, as his criticisms of Plato show, was incapable, as a substitute for the warm and tender but illiberal emotions of the home. But while the Church made the alternative to family ties celibacy [Footnote: The warm imagination of Campanella, that quaint Calabrian monastic, fired by Plato, reversed this aspect of the Church.] and participation in an organisation, Plato was far more in accordance with modern ideas in perceiving the disadvantage that would result from precluding the nobler types of character from offspring. He sought a way to achieve progeny, therefore, without the narrow concentration of the sympathies about the home, and he found it in a multiple marriage in which every member of the governing class was considered to be married to all the others. But the detailed operation of this system he put tentatively and very obscurely. His suggestions have the experimental inconsistency of an enquiring man. He left many things altogether open, and it is unfair to him to adopt Aristotle's forensic method and deal with his discussion as though it was a fully-worked-out project. It is clear that Plato intended every member of his governing class to be so "changed at birth" as to leave paternity untraceable; mothers were not to know their children, nor children their parents, but there is nothing to forbid the supposition that he intended these people to select and adhere to congenial mates within the great family. Aristotle's assertion that the Platonic republic left no scope for the virtue of continence shows that he had jumped to just the same conclusions a contemporary London errand boy, hovering a little
