Scientific theory is a contrived foothold in the chaos of living phenomena.
Most intellectual people do not believe in God, but they fear him just the same.
Love, work, and knowledge are the wellsprings of our lives, they should also govern it.
The few bad poems which occasionally are created during abstinence are of no great interest.
Only the liberation of the natural capacity for love in human beings can master their sadistic destructiveness.
I contend to be a fighter for pureness and truth. I hesitate, because I am afraid of you and your attitude towards truth. To say the truth about you is dangerous to life.
Honest pioneer work in the field of science has always been, and will continue to be, life's pilot. On all sides, life is surrounded by hostility. This puts us under an obligation.
Follow the voice of your heart, even if it leads you off the path of timid souls. Do not become hard and embittered, even if life tortures you at times. There is only one thing that counts: to live one's life well and happily.
The fact that political ideologies are tangible realities is not a proof of their vitally necessary character. The bubonic plague was an extraordinarily powerful social reality, but no one would have regarded it as vitally necessary.
Political ideological systems are based on conceptions of the natural life process. They may further or hinder the natural life process. They themselves, however, do not function at the roots of the social process. They may be democratic; in that case they further the natural human life process. They may be authoritarian and dictatorial; in that case they are its deadly enemy.
