The laws of conscience, which we pretend to be derived from nature, proceed from custom; every one, having an inward veneration for the opinions and manners approved and received amongst his own people, cannot, without very great reluctance, depart from them, nor apply himself to them without applause. In times past, when those of Crete would curse any one, they prayed the gods to engage him in some ill custom. But the principal effect of its power is, so to seize and ensnare us, that it is hardly in us to disengage ourselves from its gripe, or so to come to ourselves, as to consider of and to weigh the things it enjoins. To say the truth, by reason that we suck it in with our milk, and that the face of the world presents itself in this posture to our first sight, it seems as if we were born upon condition to follow on this track; and the common fancies that we find in repute everywhere about us, and infused into our minds with the seed of our fathers, appear to be the most universal and genuine; from whence it comes to pass, that whatever is off the hinges of custom, is believed to be also off the hinges of reason; how unreasonably for the most part, God knows.
