The moral insight of man, to say nothing of his finer spiritual insight, owes much of its penetrating clearness to the feminine element of his nature; and unless this element be developed in due proportion to the intellectual element, he can have, at best, but distorted views of right and wrong, justice and injustice. On this side of his nature, the rays of an unclouded womanhood must strike, before it can be awakened into a genial vitality, and thus impart health, vigor, and subtlety to the intellectual side. 'You cannot think,' says Ruskin (Sesame and Lilies: 2. Of Queen's Gardens), 'that the buckling on of the knight's armor by his lady's hand was a mere caprice of romantic fashion. It is the type of an eternal truth--that the soul's armor is never well set to the heart unless a woman's hand has braced it; and it is only when she braces it loosely that the honor of manhood fails.' On the other hand, woman can be a true woman, only to the degree to which she is permitted to share with man all his highest interests, to sympathize with all his noblest aims, and to work side by side with him in the regeneration of the world. That which is especially distinctive in her nature, must be subdued, toned, and guided by a greater breadth and solidity of intellectual culture; and this can be most effectually secured by co-education, and by her being afforded the opportunity to move with man along the higher planes of learning and of thought, and to have a larger share with him than she has hitherto had, in the fruits of the world's intellectual and moral conquests.
