Exploring the question of how particular laws come to be included within legal systems is a characteristic question of some theories known as theories of legal positivism
The question of whether all legal systems or even all laws, partake of some more general moral qualities is characteristic of some theories known as natural law theories
Hybrid theories (that of Dworkin) suggest that the manner in which any and every particular law becomes part of a legal system can only be understood in terms of the enterprise of law at its most general level

Natural law theory is not a single theory of law
It is the application of ethical or political theories to the question of how legal orders can acquire, or have legitimacy.
Which of the ideas presented by the different theories best serves as a source for the legitimacy of law?

Human law partook of
