Everything has changed, except our way of thinking.

I never made one of my discoveries through the process of rational thinking

Consider the concepts referred to in the words 'where', 'when', 'why', 'being', to the elucidation of which innumerable volumes of philosophy have been devoted. We fare no better in our speculations than a fish which should strive to become clear as to what is water.

I hate all the loathsome nonsense that goes with patriotism.

I refuse to make money out of my science. My laurel is not for sale like so many bales of cotton.

But could not our situation be compared to one of a menacing epidemic? People are unable to view this situation in its true light, for their eyes are blinded by passion. General fear and anxiety create hatred and aggressiveness. The adaptation to warlike aims and activities has corrupted the mentality of man; as a result, intelligent, objective and humane thinking has hardly any effect and is even suspected and persecuted as unpatriotic.

Time is an illusion.
