Einstein

“It is undeniable that the enlightened Greeks and the old Oriental sages

had achieved a higher level in this all-important field

than what is alive in our schools and universities.”

— Albert Einstein

“A calm and modest life brings more happiness

than the pursuit of success combined with constant restlessness.”

— Albert Einstein

Stupidity

“Against stupidity we have no defense. Neither protests nor force can touch it. Reasoning is of no use. Facts that contradict personal prejudices can simply be disbelieved — indeed, the fool can counter by criticizing them, and if they are undeniable, they can just be pushed aside as trivial exceptions. So the fool, as distinct from the scoundrel, is completely self-satisfied. In fact, they can easily become dangerous, as it does not take much to make them aggressive. For that reason, greater caution is called for than with a malicious one. Never again will we try to persuade the stupid person with reasons, for it is senseless and dangerous.”

— Dietrich Bonhoeffer
