But One Cannot Aim To Be Pleasing To Women Any More Than One Can Aim To Have Taste, Or Beauty Of Expression, Or Happiness; For These Things Are Not Specific Aims Which One May Learn To Attain; They Are Descriptions Of The Adequacy Of One's Living. To Try To Be Happy Is To Try To Build A Machine With No Other Specification Than That It Shall Run Noiselessly.

The Physicists Have Known Sin; And This Is A Knowledge Which They Cannot Lose.
