With the evolution of true maternity Nature was ready to proceed to her highest grades of work. Intelligence was next to be lifted to higher levels, and the order of mammals with greatest prehensile capacities, the primates with their incipient hands, were the most favourable subjects in which to carry on this process. The later stages of the marvellous story we have already passed in review. We have seen the accumulating intelligence lengthen the period of infancy, and thus prolong the relations of loving sympathy between mother and child; we have seen the human family and human society thus brought into existence; and along therewith we have recognized the necessity laid upon each individual for conforming his conduct to a standard external to himself. At this point, without encountering any breach of continuity in the cosmic process, we crossed the threshold of the ethical world, and entered a region where civilization, or the gradual perfecting of the spiritual qualities, is henceforth Nature's paramount aim. To penetrate further into this region would be to follow the progress of civilization, while the primitive canoe develops into the Cunard steamship, the hieroglyphic battle-sketch into epics and dramas, sun-catcher myths into the Newtonian astronomy, wandering tribes into mighty nations, the ethics of the clan into the moral law for all men. The story shows us Man becoming more and more clearly the image of God, exercising creative attributes, transforming his physical environment, incarnating his thoughts in visible and tangible shapes all over the world, and extorting from the abysses of space the secrets of vanished ages. From lowly beginnings, without breach of continuity, and through the cumulative action of minute and inconspicuous causes, the resistless momentum of cosmic events has tended toward such kind of consummation; and part and parcel of the whole process, inseparably wrapped up with every other part, has been the evolution of the sentiments which tend to subordinate mere egoism to unselfish and moral ends.
