The word 'happiness' would lose its meaning if it were not balanced and contrasted and compared to sadness. In comparing how an experience could have been worse we develop gratitude and happiness, while if we compare it how it could have been better we develop bitterness and sadness.
Carl JungIt seems to be very hard for people to live with riddles or to let them live, although one would think that life is so full of riddles as it is that a few more things we cannot answer would make no difference. But perhaps it is just this that is so unendurable, that there are irrational things in our own psyche which upset the conscious mind in its illusory certainties by confronting it with the riddle of its existence.
