... I came fortunately upon Darwin’s and Spencer’s works “The Data of Ethics,” “First Principles,” “Social Statics,” “The Descent of Man.” Reaching the pages which explain how man has absorbed such mental foods as were favorable to him, retaining what was salutary, rejecting what was deleterious, I remember that light came as in a flood and all was clear. Not only had I got rid of theology and the supernatural, but I had found the truth of evolution. "All is well since all grows better” became my motto, my true source of comfort. Man was not created with an instinct for his own degradation, but from the lower he had risen to the higher forms. Nor is there any conceivable end to his march to perfection. His face is turned to the light; he stands in the sun and looks upward.
