“Never attribute to malice that which can be adequately explained by stupidity, but don't rule out malice.”

“Don't think about why you question, simply don't stop questioning. Don't worry about what you can't answer, and don't try to explain what you can't know. Curiosity is its own reason. Aren't you in awe when you contemplate the mysteries of eternity, of life, of the marvelous structure behind reality? And this is the miracle of the human mind--to use its constructions, concepts, and formulas as tools to explain what man sees, feels and touches. Try to comprehend a little more each day. Have holy curiosity.”

“Is it not better for a man to die for a cause in which he believes, such as peace, than to suffer for a cause in which he does not believe, such as war?”

“Heroism on command, senseless violence, and all the loathsome nonsense that goes by the name of patriotism -how passionately I hate them!”

“Nella vita quotidiana sono il classico solitario, ma la consapevolezza di appartenere alla comunità invisibile di quelli che lottano per la verità, per la bellezza e per la giustizia mi ha risparmiato ogni sensazione di isolamento”

“Never do anything against conscience, even if the state demands it.”

“In the view of such harmony in the cosmos which I, with my limited human mind, am able to recognize, there are yet people who says there is no God. But what makes me really angry is that they quote me for support of such views. (The Expanded Quotable Einstein, Princeton University, page 214)”

“Imagination is everything”

“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.”

“In scientific thinking are always present elements of poetry. Science and music requires a thought homogeneous.”

“Due cose sono infinite: l'universo e la stupidità umana, ma riguardo l'universo ho ancora dei dubbi.”

“Die Welt wird nicht bedroht von den Menschen, die böse sind, sondern von denen, die das Böse zulassen.”

“The only sure way to avoid making mistakes is to have no new ideas.”

“If I were not a Jew I would be a Quaker.”

“What a deep [trust] in the rationality of the structure of the world and what a longing to understand even a small glimpse of the reason revealed in the world there must have been in Kepler and Newton to enable them to unravel the mechanism of the heavens in long years of lonely work!”
