"To plead the organic causation of a religious state of mind, then, in refutation of its claim to possess superior spiritual value, is quite illogical and arbitrary, unless one have already worked out in advance some psycho-physical theory connecting spiritual values in general with determinate sorts of physiological change. Otherwise none of our thoughts and feelings, not even our scientific doctrines, not even our dis-beliefs, could retain any value as revelations of the truth, for every one of them without exception flows from the state of their possessor's body at the time."

“I am against bigness and greatness in all their forms, and with the invisible molecular moral forces that work from individual to individual, stealing in through the crannies of the world like so many soft rootlets, or like the capillary oozing of water, and yet rending the hardest monuments of man's pride, if you give them time. The bigger the unit you deal with, the hollower, the more brutal, the more mendacious is the life displayed. So I am against all big organizations as such, national ones first and foremost; against all big successes and big results; and in favor of the eternal forces of truth which always work in the individual and immediately unsuccessful way, under-dogs always, till history comes, after they are long dead, and puts them on top. — You need take no notice of these ebullitions of spleen, which are probably quite unintelligible to anyone but myself.”

“"What is meant by saying that my choice of which way to walk home after the lecture is ambiguous and matter of chance?...It means that both Divinity Avenue and Oxford Street are called but only one, and that one either one, shall be chosen.”

“The mere word 'design' by itself has no consequences and explains nothing. It is the barrenest of principles. The old question of whether there is design is idle.”

“An unlearned carpenter of my acquaintance once said in my hearing: "There is very little difference between one man and another; but what little there is, is very important." This distinction seems to me to go to the root of the matter.”

“Man's chief difference from the brutes lies in the exuberant excess of his subjective propensities — his preeminence over them simply and solely in the number and in the fantastic and unnecessary character of his wants, physical, moral, aesthetic, and intellectual. Had his whole life not been a quest for the superfluous, he would never have established himself as inexpugnably as he has done in the necessary.”

“The impulse to take life strivingly is indestructible in the race.”
