Pleasure is continually disappointed, reduced, deflated, in favor of strong, noble values: Truth, Death, Progress, Struggle, Joy, etc. Its victorious rival is Desire: we are always being told about Desire, never about Pleasure.
For the rational, psychologically healthy man, the desire for pleasure is the desire to celebrate his control over reality. For the neurotic, the desire for pleasure is the desire to escape from reality.
For most men, and most circumstances, pleasure --tangible material prosperity in this world --is the safest test of virtue. Progress has ever been through the pleasures rather than through the extreme sharp virtues, and the most virtuous have leaned to excess rather than to asceticism.
Whenever I meet with anything agreeable in this world it surprises me so much -- and pleases me so much (when my passions are not interested in one way or the other) that I go on wondering for a week to come.
The goal towards which the pleasure principle impels us -- of becoming happy -- is not attainable: yet we may not -- nay, cannot -- give up the efforts to come nearer to realization of it by some means or other.
