'The possibility of all education (of which military drill is only one particular form) is based upon, the existence of this power which the nervous system possesses, of organising conscious actions into more or less unconscious, or reflex, operations. It may be laid down as a rule, that if any two mental states be called up together, or in succession, with due frequency and vividness, the subsequent production of the one of them will suffice to call up the other, and that whether we desire it or not.'[1] [1] Huxley's Elementary Physiology, pp. 284-286. The body of the accomplished man has thus become by training different from what it once was, and different from that of the rude man; it is charged with stored virtue and acquired faculty which come away from it unconsciously. Again, as to race, another authority teaches:--'Man's life truly represents a progressive development of the nervous system, none the less so because it takes place out of the womb instead of in it. The regular transmutation of motions which are at first voluntary into secondary automatic motions, as Hartley calls them, is due to a gradually effected organisation; and we may rest assured of this, that co-ordinate activity always testifies to stored-up power, either innate or acquired. 'The way in which an acquired faculty of the parent animal is sometimes distinctly transmitted to the progeny as a heritage, instinct, or innate endowment, furnishes a striking confirmation of the foregoing observations. Power that has been laboriously acquired and stored up as statical in one generation manifestly in such case becomes the inborn faculty of the next; and the development takes place in accordance with that law of increasing speciality and complexity of adaptation to external nature which is traceable through the animal kingdom; or, in other words, that law, of progress from the general to the special in development which the appearance of nerve force amongst natural forces and the complexity of the nervous system of man both illustrate. As the vital force gathers up, as it were, into itself inferior forces, and might be said to be a development of them, or, as in the appearance of nerve force, simpler and more general forces are gathered up and concentrated in a more special and complex mode of energy; so again a further specialisation takes place in the development of the nervous system, whether watched through generations or through individual life. It is not by limiting our observations to the life of the individual, however, who is but a link in the chain of organic beings connecting the past with the future, that we shall come at the full truth; the present individual is the inevitable consequence of his antecedents in the past, and in the examination of these alone do we arrive at the adequate explanation of him. It behoves us, then, having found any faculty to be innate, not to rest content there, but steadily to follow
