1869. This volume, like most textbooks on morals, has its origin in a course of instruction given by the author, in his regular college duties. Pupils who have listened to the lectures, naturally desire them in a permanent form, and in deference to this want, very generally expressed, and often urged, they are now submitted for publication, essentially as given to the classes. Moral Philosophy is the science of obligation or duty. It states and analyzes the facts connected with obligation and its perception, and determines principles of action and rules of duty. More particularly, the subjects of which it treats are moral beings, moral action, moral law, moral government, and personal rights and duties.
