Context: Justice is the constitution or fundamental law of the moral universe, the law of right, a rule of conduct for man in all his moral relations.

1780s, Letter to Peter Carr (1787)
Context: He who made us would have been a pitiful bungler, if he had made the rules of our moral conduct a matter of science. For one man of science, there are thousands who are not.
