Chapter 1

Definition and Use of the Science

Moral Philosophy, Morality, Ethics, Casuistry, Natural Law, mean all the same thing; namely, that science which teaches men their duty and the reasons of it.

The use of such a study depends upon this, that, without it, the rules of life, by which men are ordinarily governed, oftentimes mislead them, through a defect either in the rule, or in the application.

These rules are, the Law of Honour, the Law of the Land, and the Scriptures.
