Just like a man grieving because he has recently lost in his dreams some thing that he had never had in reality, or hoping that tomorrow he would dream that he found it again. That is how mathematics is created; it has its fatal flaw.

That swimming, sloping, elusive something about the dark-bluish tint of the iris which seemed still to retain the shadows it had absorbed of ancient, fabulous forests where there were more birds than tigers and more fruit than thorns, and where, in some dappled depth, man's mind had been born.

It was an interesting thing to do. Why did I write any of my books, after all? For the sake of the pleasure, for the sake of the difficulty. I have no social purpose, no moral message; I've no general ideas to exploit, I just like composing riddles with elegant solutions.

Devices which in some curious new way imitate nature are attractive to simple minds.

When I try to analyze my own cravings, motives, actions and so forth, I surrender to a sort of retrospective imagination which feeds the analytic faculty with boundless alternatives and which causes each visualized route to fork and re-fork without end in the maddeningly complex prospect of my past.

Solitude is the playfield of Satan.

for better or worse, it is the commentator who has the last word.
