“Нищо няма да допринесе за човешкото здраве и да повиши шансовете за оцеляване живота на земята толкова, колкото еволюцията на вегетарианското хранене.”

“Don't do anything that goes against your conscience, even if your country says so.”

“I fully agree with you about the significance and educational value of methodology as well as history and philosophy of science. So many people today - and even professional scientists - seem to me like somebody who has seen thousands of trees but has never seen a forest. A knowledge of the historic and philosophical background gives that kind of independence from prejudices of his generation from which most scientists are suffering. This independence created by philosophical insight is - in my opinion - the mark of distinction between a mere artisan or specialist and a real seeker after truth.

“Concerning matter, we have been all wrong. What we have called matter is energy, whose vibration has been so lowered as to be perceptible to the senses. There is no matter.”

“Never give up on what you really want to do. The person with big dreams is more powerful than one with all the facts.”

“The only difference between genius and insanity is that genius has its limits.”

“Teaching should be such that what is offered is perceived as a valuable gift and not as hard duty. Never regard study as duty but as the enviable opportunity to learn to know the liberating influence of beauty in the realm of the spirit for your own personal joy and to the profit of the community to which your later work belongs.” 

“The tendencies we have mentioned are something new for America. They arose when, under the influence of the two World Wars and the consequent concentration of all forces on a military goal, a predominantly military mentality developed, which with the almost sudden victory became even more accentuated. The characteristic feature of this mentality is that people place the importance of what Bertrand Russell so tellingly terms “naked power” far above all other factors which affect the relations between peoples. The Germans, misled by Bismarck’s successes in particular, underwent just such a transformation of their mentality—in consequence of which they were entirely ruined in less than a hundred years. I must frankly confess that the foreign policy of the United States since the termination of hostilities has reminded me, sometimes irresistibly, of the attitude of Germany under Kaiser Wilhelm II, and I know that, independent of me, this analogy has most painfully occurred to others as well. It is characteristic of the military mentality that non-human factors (atom bombs, strategic bases, weapons of all sorts, the possession of raw materials, etc.) are held essential, while the human being, his desires and thoughts—in short, the psychological factors—are considered as unimportant and secondary. Herein lies a certain resemblance to Marxism, at least insofar as its theoretical side alone is kept in view. The individual is degraded to a mere instrument; he becomes “human materiel.” The normal ends of human aspiration vanish with such a viewpoint. Instead, the military mentality raises “naked power” as a goal in itself—one of the strangest illusions to which men can succumb.”

“If someone can enjoy marching to music in rank and file, I can feel only contempt for him; he has received his large brain by mistake, a spinal cord would have been enough.”

“The religion of the future will be cosmic religion. It will transcend personal God and avoid dogma and theology.”

“Deux choses sont infinies : l’Univers et la bêtise humaine. Mais, en ce qui concerne l’Univers, je n’en ai pas encore acquis la certitude absolue.”

“I never think of the future - it comes soon enough.”

“To get to know a country, you must have direct contact with the earth. It's futile to gaze at the world through a car window.”

“I am not a genius, I am just curious. I ask many questions. and when the answer is simple, then God is answering.”

“Matter tells space how to curve, space tells matter how to move.”
