... man by nature is not a wild or unsocial creature, neither was he born so, but makes himself what he naturally is not, by vicious habit; and that again on the other side, he is civilized and grows gentle by a change of place, occupation, and manner of life, as beasts themselves that are wild by nature, become tame and tractable by housing and gentler usage...
