Those who live not by law would be justified by Custom: but, as common practice is the worst teacher that ever was, so the truth and goodness of things is not to be estimated by the entertainment and acceptance they find in the world.
BENJAMIN WHICHCOTE, Moral and Religious Aphorisms
Just because you have become accustomed to a thing, does not make it right.
BRIAN HERBERT & KEVIN J. ANDERSON, Dune: House Atreides
Custom is second nature. Be accustomed to a bald head, sufficiently accustomed, and hair on it would seem monstrous.
ISAAC ASIMOV, Prelude to Foundation
Custom is the law of one description of fools, and fashion of another; but the two parties often clash; for precedent is the legislator of the first, and novelty of the last. Custom, therefore, looks to things that are past, and fashions to things that are present, but both of them are somewhat purblind as to things that are to come.
CHARLES CALEB COLTON, Lacon
