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.

If, as we who study ourselves have learned to do, every one who hears a good sentence, would immediately consider how it does in any way touch his own private concern, every one would find, that it was not so much a good saying, as a severe lash to the ordinary stupidity of his own judgment:  but men receive the precepts and admonitions of truth, as directed to the common sort, and never to themselves; and instead of applying them to their own manners, do only very ignorantly and unprofitably commit them to memory.  But let us return to the empire of custom.

Such people as have been bred up to liberty, and subject to no other dominion but the authority of their own will, look upon all other form of government as monstrous and contrary to nature.  Those who are inured to monarchy do the same; and what opportunity soever fortune presents them with to change, even then, when with the greatest difficulties they have disengaged themselves from one master, that was troublesome and grievous to them, they presently run, with the same difficulties, to create another; being unable to take into hatred subjection itself.

’Tis by the mediation of custom, that every one is content with the place where he is planted by nature; and the Highlanders of Scotland no more pant after Touraine; than the Scythians after Thessaly.  Darius asking certain Greeks what they would take to assume the custom of the Indians, of eating the dead bodies of their fathers (for that was their use, believing they could not give them a better nor more noble sepulture than to bury them in their own bodies), they made answer, that nothing in the world should hire them to do it; but having also tried to persuade the Indians to leave their custom, and, after the Greek manner, to burn the bodies of their fathers, they conceived a still greater horror at the motion.—­[Herodotus, iii. 38.]—­Every one does the same, for use veils from us the true aspect of things.
