“A "simple aspect of science" may be defined as one which, through good fortune, I happen to understand.”

“A science which is postulated on the assumption that human beings are avaricious through all eternity is utterly devoid of point (whether in problems of distribution or any other aspect) to a person who is not avaricious.”

“The whole history of science has been the gradual realization that events do not happen in an arbitrary manner, but that they reflect a certain underlying order, which may or may not be divinely inspired.”

“Dream or nightmare, we have to live our experience as it is, and we have to live it awake. We live in a world which is penetrated through and through by science and which is both whole and real. We cannot turn it into a game simple by taking sides.”

“Philosophy, art, and science are not the mental objects of an objectified brain but the three aspects under which the brain becomes subject.”

“I will never understand all the good that a simple smile can accomplish.”
