An instructive illustration is furnished by the question of the relation of the sexes, and elsewhere (Studies in the Psychology of Sex, Vol. VI, "Sex in Relation to Society") I have sought to show that we must distinguish between marriage, which is directly the affair of the individuals primarily concerned, and procreation, which is mainly the concern of society.

See, for instance, the opinion of the former Chief Inspector of Elementary Schools in England, Mr. Edmond Holmes, What Is and What Might Be (1911). He points out that true education must be "self-realization," and that the present system of "education" is entirely opposed to self-realization. Sir John Gorst, again, has repeatedly attacked the errors of the English State system of education.
