VIRTUE OF LAW AND MORALITIES OF FULLER

Abstract

Lon Fuller, who is one of main figures of contemporary natural law theory, in his magnum opus The Morality of Law, talks about four different moralities; morality of duty, morality of aspiration, internal and external moralities of law. These are all together making a unity from teleological viewpoint. So, in this article, I, by mentioning Greek thought, will try to explain why Fuller's stand can be called virtue of law and how he is abandoning the substantive aims of natural law doctrine while justifying his own claim.
