Immortality is a belief grounded upon other men's sayings, that they knew it supernaturally; or that they knew those who knew them that knew others that knew it supernaturally.
Thomas HobbesIn 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 Hobbes
