It may be objected that if man was developed out of any kind of animal (and this is the doctrine of evolution which, if it be not proved conclusively, has great probability and great scientific analogy in its favour) he would necessarily at first possess animal instincts; that these would only gradually be lost; that in the meantime they would serve as a protection and an aid, and that pre-historic men, therefore, would have important helps and feelings which existing savages have not. And probably of the first men, the first beings worthy to be so called, this was true: they had, or may have had, certain remnants of instincts which aided them in the struggle of existence, and as reason gradually came these instincts may have waned away. Some instincts certainly do wane when the intellect is applied steadily to their subject-matter. The curious 'counting boys,' the arithmetical prodigies, who can work by a strange innate faculty the most wonderful sums, lose that faculty, always partially, sometimes completely, if they are taught to reckon by rule like the rest of mankind. In like manner I have heard it said that a man could soon reason himself out of the instinct of decency if he would only take pains and work hard enough. And perhaps other primitive instincts may have in like manner passed away. But this does not affect my argument. I am only saying that these instincts, if they ever existed, DID pass away--that there was a period; probably an immense period as we reckon time in human history, when pre-historic men lived much as savages live now, without any important aids and helps. The proofs of this are to be found in the great works of Sir John Lubbock and Mr. Tylor, of which I just now spoke. I can only bring out two of them here. First, it is plain that the first pre-historic men had the flint tools which the lowest savages use, and we can trace a regular improvement in the finish and in the efficiency of their simple instruments corresponding to that which we see at this day in the upward transition from the lowest savages to the highest. Now it is not conceivable that a race of beings with valuable instincts supporting their existence and supplying their wants would need these simple tools. They are exactly those needed by very poor people who have no instincts, and those were used by such, for savages are the poorest of the poor. It would be very strange if these same utensils, no more no less, were used by beings whose discerning instincts made them in comparison altogether rich. Such a being would know how to manage without such things, or if it wanted any, would know how to make better.
