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

“Който обича да марширува, напразно има мозък в главата — гръбначният би бил достатъчен.”

“I know quite certainly that I myself have no special talent; curiosity, obsession and dogged endurance, combined with self-criticism, have brought me to my ideas.”

“If it isn't urgent, worry about it later”

“The more cruel the wrong that men commit against an individual or a people, the deeper their hatred and contempt for their victim. Conceit and false pride on the part of a nation prevent the rise of remorse for its crime.”

“In the matter of physics, the first lessons should contain nothing but what is experimental and interesting to see. A pretty experiment is in itself often more valuable than twenty formulae extracted from our minds.”

“It is clear that all the valuable things, material, spiritual, and moral, which we receive from society can be traced back through countless generations to certain creative individuals. The use of fire, the cultivation of edible plants, the steam engine—each was discovered by one man.”

“I want to oppose the idea that the school has to teach directly that special knowledge and those accomplishments which one has to use later directly in life. The demands of life are much too manifold to let such a specialized training in school appear possible [...] The development of general ability for independent thinking and judgement should always be placed foremost.”

“Phantasie ist wichtiger als Wissen, denn Wissen ist begrenzt.”

“There are times when one feels liberated from one’s limits and human imperfections. At such moments, we see ourselves there, in a little corner of our little planet, our eyes fixed in wonder on the cold and yet deep beauty of that which is eternal, that which is elusive. Life and death are fused together and there is no evolution, nor destination, there is only BEING.”

“I fear the day that technology will surpass our human interaction. The world will have a generation of idiots.”

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

“I am a deeply religious nonbeliever. This is a somewhat new kind of religion.”

“Per perdere la testa, bisogna averne una...”

“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.”
