“Now I have two immediate objects in view. The first is to devote myself to the evolutionary life more thoroughly than I have yet done—to think, speak, do nothing but what is evolutionary. Hitherto I have been little more than a passive Evolutionist. Henceforth I shall be the active agent, the apostle of Evolution. I shall give Evolution ample opportunity to vindicate my fitness, and that as publicly as possible in order to convert others.”
