“There is no absurdity so palpable but that it may be firmly planted in the human head if you only begin to inculcate it before the age of five, by constantly repeating it with an air of great solemnity.”

“But it is common knowledge that religions don’t want conviction, on the basis of reasons, but faith, on the basis of revelation. And the capacity for faith is at its strongest in childhood: which is why religions apply themselves before all else to getting these tender years into their possession. It is in this way, even more than by threats and stories of miracles, that the doctrines of faith strike roots: for if, in earliest childhood, a man has certain principles and doctrines repeatedly recited to him with abnormal solemnity and with an air of supreme earnestness such as he has never before beheld, and at the same time the possibility of doubt is never so much as touched on, or if it is only in order to describe it as the first step towards eternal perdition, then the impression produced will be so profound that in almost every case the man will be almost incapable of doubting this doctrine as of doubting his own existence, so that hardly one in a thousand will then possess the firmness of mind seriously and honestly to ask himself: is this true?”

“What disturbs and depresses young people is the hunt for happiness on the firm assumption that it must be met with in life. From this arises constantly deluded hope and so also dissatisfaction. Deceptive images of a vague happiness hover before us in our dreams, and we search in vain for their original. Much would have been gained if, through timely advice and instruction, young people could have had eradicated from their minds the erroneous notion that the world has a great deal to offer them.”

“Writers may be classified as meteors, planets, and fixed stars. They belong not to one system, one nation only, but to the universe. And just because they are so very far away, it is usually many years before their light is visible to the inhabitants of this earth.”

“Students and scholars of all kinds and of every age aim, as a rule, only at information, not insight. They make it a point of honour to have information about everything, every stone, plant, battle, or experiment and about all books, collectively and individually. It never occurs to them that information is merely a means to insight, but in itself is of little or no value.”

“It may sometimes happen that a truth, an insight, which you have slowly and laboriously puzzled out by thinking for yourself could have easily have been found already written in a book: but it is a hundred times more valuable if you have arrived at it by thinking for yourself. For only then will it enter your thought system as an integral part and living member, be perfectly and firmly consistent with it and in accord with all its other consequences and conclusions, bear the hue, colour and stamp of your whole manner of thinking, and have arrived at just the moment it was needed ; thus it will stay firmly and forever lodged in your mind.”

“How very paltry and limited the normal human intellect is, and how little lucidity there is in the human consciousness, may be judged from the fact that, despite the ephemeral brevity of human life, the uncertainty of our existence and the countless enigmas which press upon us from all sides, everyone does not continually and ceaselessly philosophize, but that only the rarest of exceptions do.”
