In sum, all actions and habits are to be esteemed good or evil by their causes and usefulness in reference to the commonwealth, and not by their mediocrity, nor by their being commended. For several men praise several customs, and, contrarily, what one calls vice, another calls virtue, as their present affections lead them.
Thomas HobbesCompetition of praise inclineth to a reverence of antiquity. For men contend with the living, not with the dead.
Thomas Hobbes
