“The loosening of the marriage bond, that is the gradual return to a temporary union made and broken by mutual consent…reverts to what it was at first…The social vision…returns to regard the present only. Pride in the past, responsibility for the future, both disappear. And when a generation arrives which has known no sterner discipline, but which spends its early years in an atmosphere in submission to impulse, it does not add one whit to what has gone before, but, sinking into unrelieved lethargy, ekes out its meagre existence in the grip of forces which it is no longer able to control. Its energy sapped by its own indulgence, its vision reduced to a single dimension, it finds that it can no longer cope with the ultimate causes of things, and there comes a loss of affirmation, a failure of nerve, a denial of the gods, and a despondent fear of the future.”
