“Without the constantly living and articulated experience of absurdity, there would be no reason to attempt to do something meaningful. And on the contrary, how can one experience one's own absurdity if one is not constantly seeking meaning?”

Physics and Philosophy (1958)
Context: I remember discussions with Bohr which went through many hours till very late at night and ended almost in despair; and when at the end of the discussion I went alone for a walk in the neighbouring park I repeated to myself again and again the question: Can nature possibly be so absurd as it seemed to us in these atomic experiments?

What I Believe (1938)
Context: On they go — an invincible army, yet not a victorious one. The aristocrats, the elect, the chosen, the Best People — all the words that describe them are false, and all attempts to organize them fail. Again and again Authority, seeing their value, has tried to net them and to utilize them as the Egyptian Priesthood or the Christian Church or the Chinese Civil Service or the Group Movement, or some other worthy stunt. But they slip through the net and are gone; when the door is shut, they are no longer in the room; their temple, as one of them remarked, is the holiness of the Heart's affections, and their kingdom, though they never possess it, is the wide-open world.
With this type of person knocking about, and constantly crossing one's path if one has eyes to see or hands to feel, the experiment of earthly life cannot be dismissed as a failure. But it may well be hailed as a tragedy, the tragedy being that no device has been found by which these private decencies can be transmitted to public affairs. As soon as people have power they go crooked and sometimes dotty as well, because the possession of power lifts them into a region where normal honesty never pays.
