second and better nature, is the very work with which education is concerned. There is room, however, for misunderstanding here, and this I must pause to guard against; I must not be interpreted as saying that all natural feelings or actions are to be crushed out by a cold, reasoning logic. But it must be remembered that every virtue has its negative representative, and that this negative phase is simply and only the same virtue, but in an uneducated state, and not at all another and different thing; as, for instance, license is not different in its essence from self-control--it is only uneducated self-control. Obstinacy is merely uneducated firmness, and the worst forms of barbarous superstition are but the outcome of uneducated reverence. The lawlessness and bravado of our American children and youth, so severely commented upon by foreigners, are simply an index of the uneducated state of the greatest amount of directive force that the world has ever seen. A fatal error is committed in education when this central truth is overlooked, as when one treats these manifestations as in themselves wrong, instead of recognizing their value, and bending the energies in their proper direction. If a missionary should begin his work by destroying in the mind of the savage all reverence for his own and only gods, he would have sawed off the branch on which he himself hoped to stand, and it were wise for him to make his escape from the country as soon as possible. SEXUAL EDUCATION. Up to the period of life at which the sexes diverge, that is, up to the time when the boy becomes a man and the girl a woman, the physical system pursues the even tenor of development, broken only by the two marked advances of the cutting of the first and second teeth. But now, the strength of the general system is supposed, in the counsels of the Creator, to have attained sufficient strength and firmness to be fully capable of assuming a new duty. In both sexes, organs up to this time quiescent, that is, as to any functional action, take on rapidly an independent life, assert their own character, and take up their peculiar work. Heretofore, all the physical development of the child has been for self alone; the gradual growth of each organism has pointed to nothing outside; each has been in a manner isolated. But now we have a foreshadowing of a nobler meaning to human life, for man is not to be alone, an isolated individual; he attains his highest significance only in relation to others.[8] I say it is supposed that by thirteen or fourteen years of steady _educated_ growth, the system in both sexes has acquired strength enough to assume this last duty; and if this growth has been educated growth in both sexes, it does do so. I am considering, however, only the girls, and all that is said hereafter must be understood as applying specially to them. It makes its first trial of its newly acquired power, and, in a well-trained organism, such as we
