214 NATURAL SELECTION ixpigeon, the production of which are equally beyond itsundirected power.The objections which in this essay I have taken to theview that the same law which appears to have sufficed forthe development of animals has been alone the cause of man'ssuperior physical and mental nature, will, I have no doubt,be overruled and explained away. But I venture to thinkthey will nevertheless maintain their ground, and that theycan only be met by the discovery of new facts or new laws,of a nature very different from any yet known to us. I canonly hope that my treatment of the subject, though necessarilyvery meagre, has been clear and intelligible and that;itmay prove suggestive both to the opponents and to theupholders of the theory of natural selection.
