“There is only one thing I will not concede: that it might be meaningless to strive in a good cause.”

“The only thing I can recommend at this stage is a sense of humor, an ability to see things in their ridiculous and absurd dimensions, to laugh at others and at ourselves, a sense of irony regarding everything that calls out for parody in this world. In other words, I can only recommend perspective and distance.”

“In any case, ideals are something we strive for; they are somewhere on the horizon of our efforts; they provide meaning and direction; they are not, however, static quotas that we either fulfill or do not.”

“... no one ever develops and achieves self-awareness in a vacuum, beyond all ears and systems. The period you grow up in and mature in always influences your thinking. This in itself requires no self-criticism. What is more important is how you have allowed yourself to be influenced, whether by good or by evil.”

“Without a global revolution in the sphere of human consciousness, nothing will change for the better in the sphere of our being as humans, and the catastrophe toward which this world is headed — be it ecological, social, demographic or a general breakdown of civilization — will be unavoidable. If we are no longer threatened by world war or by the danger that the absurd mountains of accumulated nuclear weapons might blow up the world, this does not mean that we have definitely won. We are still incapable of understanding that the only genuine backbone of all our actions, if they are to be moral, is responsibility.”

“At one time, the state of culture in Czechoslovakia was described, rather poignantly, as a 'Biafra of the spirit'. . . I simply do not believe that we have all lain down and died. I see far more than graves and tombstones around me. I see evidence of this in . . . expensive books on astronomy printed in a hundred thousand copies (they would hardly find that many readers in the USA) . . .”

“Hope is definitely not the same thing as optimism. It is not the conviction that something will turn out well, but the certainty that something makes sense, regardless of how it turns out.”
