Even the preliminary knowledge, what the differences between the sexes now are, apart from all question as to how they are made what they are, is still in the crudest and most incomplete state. Medical practitioners and physiologists have ascertained, to some extent, the differences in bodily constitution; and this is an important element to the psychologist: but hardly any medical practitioner is a psychologist. Respecting the mental characteristics of women; their observations are of no more worth than those of common men. It is a subject on which nothing final can be known, so long as those who alone can really know it, women themselves, have given but little testimony, and that little, mostly suborned. It is easy to know stupid women. Stupidity is much the same all the world over. A stupid person's notions and feelings may confidently be inferred from those which prevail in the circle by which the person is surrounded. Not so with those whose opinions and feelings are an emanation from their own nature and faculties. It is only a man here and there who has any tolerable knowledge of the character even of the women of his own family. I do not mean, of their capabilities; these nobody knows, not even themselves, because most of them have never been called out. I mean their actually existing thoughts and feelings. Many a man thinks he perfectly understands women, because he has had amatory relations with several, perhaps with many of them. If he is a good observer, and his experience extends to quality as well as quantity, he may have learnt something of one narrow department of their nature--an important department, no doubt. But of all the rest of it, few persons are generally more ignorant, because there are few from whom it is so carefully hidden. The most favourable case which a man can generally have for studying the character of a woman, is that of his own wife: for the opportunities are greater, and the cases of complete sympathy not so unspeakably rare. And in fact, this is the source from which any knowledge worth having on the subject has, I believe, generally come. But most men have not had the opportunity of studying in this way more than a single case: accordingly one can, to an almost laughable degree, infer what a man's wife is like, from his opinions about women in general. To make even this one case yield any result, the woman must be worth knowing, and the man not only a competent judge, but of a character so sympathetic in itself, and so well adapted to hers, that he can either read her mind by sympathetic intuition, or has nothing in himself which makes her shy of disclosing it. Hardly anything, I believe, can be more rare than this conjunction. It often happens that there is the most complete unity of feeling and community of interests as to all external things, yet the one has as little admission into the internal life of the other as if they were common acquaintance. Even with true affection,
