Every gain made by individuals or societies is almost instantly taken for granted. The luminous ceiling toward which we raise our longing eyes becomes, when we have climbed to the next floor, a stretch of disregarded linoleum beneath our feet.

Love casts out fear; but conversely fear casts out love. And not only love. Fear also casts out intelligence, casts out goodness, casts out all thought of beauty and truth.

Actual happiness always looks pretty squalid in comparison with the overcompensations for misery. And, of course, stability isn't nearly so spectacular as instability.
