bear upon the very young child strongly affect its later growth in good or evil, yet this period between fourteen and twenty-five is the most critical time of preparation for the work of adult life. Another important fact announced by physiological observation, is the absolute necessity of establishing a proper government of the human faculties, by the growth of intelligent self-control. Reason, not Instinct, is the final guide of our race. We cannot grow, as do the lower animals, by following out the blind promptings of physical nature. From the earliest moment of existence, intelligence must guide the infant. At first this guiding intelligence is that of the mother, and through all the earlier stages of life, a higher outside intelligence must continue to provide the necessary conditions of growth, until the gradual mental development of the child fits it for independent individual guidance. The great difficulty of education lies in the adjustment of intelligence, for there are antagonisms to be encountered. There is first of all to be considered the adaptation of parental intelligence to the large proportion of indispensable physical instinct, with which each child is endowed by Nature. There is next the adjustment of the two intelligences, the parental and filial. These relations are constantly changing, and the true wisdom of education consists in meeting these changes rightly. It is very important to observe that each new phase of life, each new faculty, begins in the child-like way--that is to say, there is always a large proportion of the blind, instinctive element which absolutely needs a higher guidance. The instinctive life of the body always necessarily exists, and, therefore, constantly strives to make itself felt. This life of sensation will (in many different ways) obtain a complete mastery over the individual, if Reason does not exist, and grow into a controlling force. This danger of an undue predominance of the instinctive force is emphatically true of the life of sex. It begins, child-like, in a tumult of overpowering sensations--sensations and emotions which need as wisely-arranged conditions and as high a guiding influence as does the early life of the child. At this period of life, an adjustment of the parental and filial intelligence is required, quite as wisely planned as in childhood, in order to secure the gradual growth of intelligent self-control in the young life of sex. If we do not recognise this necessity, or fail to exercise this directing influence, we do not perceive the crowning obligation of the older to the younger generation. However much parents may now shrink from this obligation, and, owing to incorrect views of sex, be really unable to exercise the kind of influence required, the necessity for such influence, nevertheless, exists as a law of human nature, unchangeable, rooted in the human constitution. It is Nature’s method, that every new faculty requires intelligent control from the outset,
