As an ill air may endanger a good constitution, so may a place of ill example endanger a good man, nay, there are some places that have a kind of privilege to be licentious, and where luxury and dissolution of manners seem to be lawful; for great examples give both authority and excuse to wickedness. Those places are to be avoided as dangerous to our manners. Hannibal himself was unmanned by the looseness of Campania, and though a conqueror by his arms, he was overcome by his pleasures. I would as soon live among butchers as among cooks—not but a man may be temperate in any place—but to see drunken men staggering up and down everywhere, and only the spectacle of lust, luxury and excess before our eyes, it is not safe to expose ourselves to the temptation. If the victorious Hannibal himself could not resist it, what shall become of us then that are subdued, and give ground to our lusts already? He that has to do with an enemy in his breast, has a harder task upon him than he that is to encounter one in the field; his hazard is greater if he loses ground, and his duty is perpetual, for he has no place or time for rest. If I give way to pleasure, I must also yield to grief, to poverty, to labor, ambition, anger, until I am torn to pieces by my misfortunes and lusts. But against all this philosophy propounds a liberty, that is to say, a liberty from the service of accidents and fortune. There is not anything that does more mischief to mankind than mercenary masters and philosophy, that do not live as they teach—they give a scandal to virtue. How can any man expect that a ship should steer a fortunate course, when the pilot lies wallowing in his own vomit? It is a usual thing first to learn to do ill ourselves, and then to instruct others to do so: but that man must needs be very wicked that has gathered into himself the wickedness of other people.
