But to any further definition of the marriage relation the World State of Utopia will not commit itself. The wide range of relationships that are left possible, within and without the marriage code, are entirely a matter for the individual choice and imagination. Whether a man treat his wife in private as a goddess to be propitiated, as a "mystery" to be adored, as an agreeable auxiliary, as a particularly intimate friend, or as the wholesome mother of his children, is entirely a matter for their private intercourse: whether he keep her in Oriental idleness or active co-operation, or leave her to live her independent life, rests with the couple alone, and all the possible friendship and intimacies outside marriage also lie quite beyond the organisation of the modern State. Religious teaching and literature may affect these; customs may arise; certain types of relationship may involve social isolation; the justice of the statesman is blind to such things. It may be urged that according to Atkinson's illuminating analysis [Footnote: See Lang and Atkinson's Social Origins and Primal Law.] the control of love-making was the very origin of the human community. In Utopia, nevertheless, love-making is no concern of the State's beyond the province that the protection of children covers. [Footnote: It cannot be made too clear that though the control of morality is outside the law the State must maintain a general decorum, a systematic suppression of powerful and moving examples, and of incitations and temptations of the young and inexperienced, and to that extent it will, of course, in a sense, exercise a control over morals. But this will be only part of a wider law to safeguard the tender mind. For example, lying advertisements, and the like, when they lean towards adolescent interests, will encounter a specially disagreeable disposition in the law, over and above the treatment of their general dishonesty.] Change of function is one of the ruling facts in life, the sac that was in our remotest ancestors a swimming bladder is now a lung, and the State which was once, perhaps, no more than the jealous and tyrannous will of the strongest male in the herd, the instrument of justice and equality. The State intervenes now only where there is want of harmony between individuals--individuals who exist or who may presently come into existence. Section 6
