Why should men dispute concerning the reality of virtue, and whether it be founded in the nature of things, which yet surely is not matter of question; but why should this, I say, be disputed, when every man carries about him this passion, which affords him demonstration that the rules of justice and equity are to be the guide of his actions ? For every man naturally feels an indignation upon seeing instances of villany and baseness, and therefore cannot commit the same without being self-condemned. ”
