The girl at this period is also passing through a crisis, but this fact is better understood by her friends than is the crisis of the boy's life. Her parents are anxious that she shall pass the crisis safely, and they have more patience with her eccentricities. She, too, often shows nervousness, irritability, petulance, or willfulness. She has headaches and backaches, she manifests lassitude and weariness, and is, perhaps, quite changed from her former self. She weeps easily or over nothing at all. She is dissatisfied with herself and the whole world. She feels certain vague, romantic longings that she could not explain if she tried. She inclines toward the reading of sensational love stories, and if not well instructed and self-respecting may be easily led into flirtations or conduct that later in life may make her blush to remember. Certain physical changes begin to be manifest. She increases rapidly in height, her figure grows fuller and more rounded, her breasts are often sore and tender. Hair makes its appearance on the body, and altogether she seems to be blossoming out into a fuller and riper beauty. She is changing from the girl to the woman, and this is a matter of sex. At this time the organs of sex, which have been dormant, awaken and take on their activity, and it is this awakening which is making itself felt throughout her whole organization. We are sometimes apt to think that sex is located in certain organs only, but in truth sex, while centralized in the reproductive organs, makes itself manifest throughout the whole organization. I used to feel somewhat indignant when I heard people talk of sex in mind, and I boldly asserted that it did not exist, that intellect was neuter and had no reference to sex; but I do not feel so now. When I see what an influence the awakening of sex has upon the entire body and upon the character, I am led to believe that sex inheres in mind as well. That does not mean that the brain of one sex is either inferior or superior to the other; it means only that they differ; that men and women see things from different standpoints; that they are the two eyes of the race, and the use of both is needed to a clear understanding of any problem of human interest. You know that the true perspective of objects cannot be had with one eye only, for each eye has its own range of vision, and one eye can see much farther on one side of an object than the other can. You can try this for yourself. If, then, in viewing the vital problems of life we have the man's view only or the woman's view only, we have not the true perspective. We cannot say that either has superior powers of vision, but we can say that they differ, as this difference is inherent in them as men and women, and not merely as individuals.
