The modern antagonist of the equality of the sexes would argue that the differences between men and women are not confined to the single point urged by Plato; that sensibility, gentleness, grace, are the qualities of women, while energy, strength, higher intelligence, are to be looked for in men. And the criticism is just: the differences affect the whole nature, and are not, as Plato supposes, confined to a single point. But neither can we say how far these differences are due to education and the opinions of mankind, or physically inherited from the habits and opinions of former generations. Women have been always taught, not exactly that they are slaves, but that they are in an inferior position, which is also supposed to have compensating advantages; and to this position they have conformed. It is also true that the physical form may easily change in the course of generations through the mode of life; and the weakness or delicacy, which was once a matter of opinion, may become a physical fact. The characteristics of sex vary greatly in different countries and ranks of society, and at different ages in the same individuals. Plato may have been right in denying that there was any ultimate difference in the sexes of man other than that which exists in animals, because all other differences may be conceived to disappear in other states of society, or under different circumstances of life and training. The first wave having been passed, we proceed to the second—community of wives and children. ‘Is it possible? Is it desirable?’ For as Glaucon intimates, and as we far more strongly insist, ‘Great doubts may be entertained about both these points.’ Any free discussion of the question is impossible, and mankind are perhaps right in not allowing the ultimate bases of social life to be examined. Few of us can safely enquire into the things which nature hides, any more than we can dissect our own bodies. Still, the manner in which Plato arrived at his conclusions should be considered. For here, as Mr. Grote has remarked, is a wonderful thing, that one of the wisest and best of men should have entertained ideas of morality which are wholly at variance with our own. And if we would do Plato justice, we must examine carefully the character of his proposals. First, we may observe that the relations of the sexes supposed by him are the reverse of licentious: he seems rather to aim at an impossible strictness. Secondly, he conceives the family to be the natural enemy of the state; and he entertains the serious hope that an universal brotherhood may take the place of private interests—an aspiration which, although not justified by experience, has possessed many noble minds. On the other hand, there is no sentiment or imagination in the connections which men and women are supposed by him to form; human beings return to the level of the animals, neither exalting to heaven, nor yet abusing the natural instincts.
