One declaims endlessly against the passions; one imputes all of man's suffering to them. One forgets that they are also the source of all his pleasures.Denis Diderot
Many men are deeply moved by the mere semblance of suffering in a woman; they take the look of pain for a sign of constancy or of love.Honoré de Balzac
Illusions commend themselves to us because they save us pain and allow us to enjoy pleasure instead. We must therefore accept it without complaint when they sometimes collide with a bit of reality against which they are dashed to pieces.Sigmund Freud
We have long observed that every neurosis has the result, and therefore probably the purpose, of forcing the patient out of real life, of alienating him from actuality.Sigmund Freud
