Civilization can only revive when there shall come into being in a number of individuals a new tone of mind independent of the one prevalent among the crowd and in opposition to it. A new public opinion must be created privately and unobtrusively. The existing one is maintained by the press, by propaganda, by organization, and by financial influences which are at its disposal. The unnatural way of spreading ideas must be opposed by the natural one, which goes from man to man and relies solely on the truth of the thoughts and the hearer's receptiveness of new truth.

Because I have confidence in the power of truth and in the spirit, I believe in the future of mankind. Affirmation of the world and of life contains within itself an optimistic willing and hoping which can never be lost. It is, therefore, never afraid to face the dismal reality and to see it as it really is.

The path of awakening is not about becoming who you are. Rather it is about unbecoming who you are not.

Every patient carries her or his own doctor inside.

But merely accepting authoritarian truth, even if that truth has some virtue, does not bring skepticism to an end. To blindly accept a truth one has never reflected upon retards the advance of reason. Our world rots in deceit. . . . Just as a tree bears the same fruit year after year and at the same time fruit that is new each year, so must all permanently valuable ideas be continually created anew in thought. But our age pretends to make a sterile tree bear fruit by tying fruits of truth onto its branches.

Preservation of life is the only true joy.

We cannot understand what happens in the universe. What is glorious in it is united with what is full of horror. What is full of meaning is united to what is senseless. The spirit of the universe is at once creative and destructive — it creates while it destroys and destroys while it creates, and therefore it remains to us a riddle. And we must inevitably resign ourselves to this.
