Few people have ever seriously wished to be exclusively rational. The good life which most desire is a life warmed by passions and touched with that ceremonial grace which is impossible without some affectionate loyalty to traditional forms and ceremonies.

Habit is the enormous flywheel of society, its most precious conservative agent. There is no more miserable human being than one in whom nothing is habitual but indecision. Full half the time of such a man goes to the deciding, or regretting, of matters which ought to be so ingrained in him as practically not to exist for his consciousness at all.
