In this investigation of the philosophical attainments of former times, in morals, religion, and law, I am limited by the extent of this course, both as regards the principles of which I shall give the history, and the works in which they are made the subject of inquiry. This historical sketch can embrace only the general rules of conduct, the leading principles and fundamental truths of morality; and the most interesting systems advanced in ancient or modern times. I proceed to give a brief account of the Moral Philosophy of antiquity, that is, before the introduction of Christianity. (PsycINFO Database Record (c) 2016 APA, all rights reserved)
