“Two things are infinite: the universe and human stupidity; and I'm not sure about the universe.”

“This topic brings me to that worst outcrop of herd life, the military system, which I abhor... This plague-spot of civilization ought to be abolished with all possible speed. Heroism on command, senseless violence, and all the loathsome nonsense that goes by the name of patriotism -- how passionately I hate them!”

“Look to the stars and from them learn.”

“When we first got married, we made a pact. It was this: In our life together, it was decided I would make all of the big decisions and my wife would make all of the little decisions. For fifty years, we have held true to that agreement. I believe that is the reason for the success in our marriage. However, the strange thing is that in fifty years, there hasn’t been one big decision.”

“The value of a man should be seen in what he gives and not in what he is able to receive.”

“A clever person solves a problem. A wise person avoids it.”

“Wisdom is not a product of schooling but of the lifelong attempt to acquire it.”

“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.”

“What really interests me is whether God had any choice in the creation of the World.”

“The woman who follows the crowd will usually go no further than the crowd. The woman who walks alone is likely to find herself in places no one has ever been before.”

“I love to travel, but hate to arrive”

“Gravitation cannot be held responsible for people falling in love. How on earth can you explain in terms of chemistry and physics so important a biological phenomenon as first love? Put your hand on a stove for a minute and it seems like an hour. Sit with that special girl for an hour and it seems like a minute. That's relativity.”

“I don't know, I don't care, and it doesn't make any difference!”

“The best way to cheer yourself is to cheer somebody else up.”

“I am not more gifted than the average human being. If you know anything about history, you would know that is so--what hard times I had in studying and the fact that I do not have a memory like some other people do… I am just more curious than the average person and I will not give up on a problem until I have found the proper solution. This is one of my greatest satisfactions in life--solving problems--and the harder they are, the more satisfaction do I get out of them. Maybe you could consider me a bit more patient in continuing with my problem than is the average human being. Now, if you understand what I have just told you, you see that it is not a matter of being more gifted but a matter of being more curious and maybe more patient until you solve a problem.”
