“A French essayist has said: 'What is terrible when you seek the truth, is that you find it.' You find it, and then you are no longer free to follow the biases of your personal circle, or to accept fashionable clichés. I immediately discerned within the Russian Revolution the seeds of such serious evils as intolerance and the drive towards the persecution of dissent. These evils originated in an absolute sense of possession of the truth, grafted upon doctrinal rigidity. What followed was contempt for the man who was different, of his arguments and way of life. Undoubtedly, one of the greatest problems which each of us has to solve in the realm of practice is that of accepting the necessity to maintain, in the midst of intransigence which comes from steadfast beliefs, a critical spirit towards these same beliefs and a respect for the belief that differs. In the struggle, it is the problem of combining the greatest practical efficiency with respect for the man in the enemy - in a word, of war without hate.”

“[Seeing clearly] is not so difficult to achieve, and yet it is rather unusual. To my mind, it is less a question of an exalted or shrewd intelligence than of good sense, goodwill and a certain sort of courage to enable one to rise above both the pressures of one's environment and the natural inclination to close one's eyes to facts, a temptation that arises from our immediate interests and from the fear which problems inspire in us.

“It was good of Friedrich Nietzsche to declare God dead – I declare that he has never been born. It is a created fiction, an invention, not a discovery. Do you understand the difference between invention and discovery? A discovery is about truth, an invention is manufactured by you. It is man-manufactured fiction. Certainly it has given consolation, but consolation is not the right thing! Consolation is opium. It keeps you unaware of the reality, and life is flowing past you so quickly – seventy years will be gone soon. Anybody who gives you a belief system is your enemy, because the belief system becomes the barrier for your eyes, you cannot see the truth. The very desire to find the truth disappears. But in the beginning it is bitter if all your belief systems are taken away from you. The fear and anxiety which you have been suppressing for millennia, which is there, very alive, will surface immediately. No God can destroy it, only the search for truth and the experience of truth – not a belief – is capable of healing all your wounds, of making you a whole being. And the whole person is the holy person to me”

“I believe that ideas such as absolute certitude, absolute exactness, final truth, etc. are figments of the imagination which should not be admissible in any field of science... This loosening of thinking seems to me to be the greatest blessing which modern science has given to us. For the belief in a single truth and in being the possessor thereof is the root cause of all evil in the world.”

“It is a difference of opinion which does not admit of proof. We each begin probably with a little bias towards our own sex, and upon that bias build every circumstance in favour of it which has occurred within our own circle;”
