If this be true of the physical element of sex, it is equally true of the mental element. No careful observer can fail to remark the larger proportionate amount of thought and feeling, as compared with the total vital force of the individual, which we find given by women to all that concerns the subject of sex. Words spoken, slight courtesies rendered, excite a more permanent interest in women. That which may be the mere passing thought or action of the man, at once forgotten by him, obliterated by a thousand other intellectual or practical interests in his life, often make a quite undue impression upon the woman. Incidents are thought of over and over again, and are supposed to mean much more than they do mean. A romance or a scandal, a tale of true or false love, will always excite interest, where business, politics, science, or philosophy will fall upon deaf ears. All that concerns the mental aspect of sex, the special attraction which draws one sex towards the other, is exhibited in greater proportionate force by women, is more steady and enduring, and occupies a larger amount of their thought and interest. The frivolity and ephemeral character of the seducer’s impulses, as compared with the earnestness of the seduced, illustrates the profounder character of sexual passion in woman. Wide-spread unhappiness, social disturbance, and degradation continually arise from the vital force of human sex in woman, unguarded, unguided, and unemployed. Passion and appetite are not identical. The term ‘passion,’ it should always be remembered, necessarily implies a mental element. For this reason it is employed exclusively in relation to the powers of the human being, not to those of the brute. Passion rises into a higher rank than instinct or physical impulse, because it involves the soul of man. In sexual passion this mental, moral, or emotional principle is as emphatically sex as any physical instinct, and it grows with the proportional development of the nervous system. This mental element of human sex exists in major proportion in the vital force of women, and justifies the statement that the compound faculty of sex is as strong in woman as in man. Those who deny sexual feeling to women, or consider it so light a thing as hardly to be taken into account in social arrangements, confound appetite and passion; they quite lose sight of this immense spiritual force of attraction, which is distinctly human sexual power, and which exists in so very large a proportion in the womanly nature. The impulse towards maternity is an inexorable but beneficent law of woman’s nature, and it is a law of sex.
