“There are sacraments of evil as well as of good about us, and we live and move to my belief in an unknown world, a place where there are caves and shadows and dwellers in twilight. It is possible that man may sometimes return on the track of evolution, and it is my belief that an awful lore is not yet dead.”

“New struggles. -- After Buddha was dead, they still showed his shadow in a cave for centuries -- a colossal, horrible shadow. God is dead, but given the way people are, there may still be caves for millennia in which his shadow is displayed. -- And we -- we must still defeat his shadow as well!”

“The propounders of what are called the "ethics of evolution," when the 'evolution of ethics' would usually better express the object of their speculations, adduce a number of more or less interesting facts and more or less sound arguments, in favour of the origin of the moral sentiments, in the same way as other natural phenomena, by a process of evolution. I have little doubt, for my own part, that they are on the right track; but as the immoral sentiments have no less been evolved, there is, so far, as much natural sanction for the one as the other. The thief and the murderer follow nature just as much as the philanthropist. Cosmic evolution may teach us how the good and the evil tendencies of man may have come about; but, in itself, it is incompetent to furnish any better reason why what we call good is preferable to what we call evil than we had before.”

“According to how gifted we are, we are all given a large or small key to this treasury of wonders. I have been blessed with a small key to the world of the young. It's a place where good and evil are clearly stamped. It's a place where the better part of human nature triumphs over tragedies, and where innocence rides high. It is a great pleasure to write there, because the young have what the rest of us only envy, and that is a belief in goodness and perpetual hope. ”

“God is dead, but considering the state the species man is in, there will perhaps be caves, for ages yet, in which his shadow will be shown.”

“Nothing can shake my belief that this world is the fruit of a dark god whose shadow I extend.”
