La ley natural puede ser comprendida en tres sentidos: ley de nuestra razón práctica, ley impresa en la naturaleza y como ley de Dios

LITERAL, p. 2

But first, what is a theory of natural law a theory of? The question can be approached in th ree ways. In the first place, natural law can be regarded as a matter of cognition. Thus, when a theorist reconnects debate about Justice back to first principles, from which the mind can lay out properly considered and argued conclusions, he can be said to have (or practice) a theory of natural law. In the second place, natural law can be regarded as an issu e of nature or human nature, in which case it is a problem not only of epistemology and logic but also of how practical reason is situated in a broader or der of causality. Third, natural law can be approached not only as order in the mind or order in nature but also as the ordinance of a divine lawgiver.

Discourse about natural law can gravitate toward any one or a combination of this three foci: law in the human mind, in nature and in the mind of God. Contemporary literature on this subject shows there is little or no agreement as to how the three foci ought to be integrated. For there is no general agreement about what should count as a proper problem, much less about what philosophical instruments to apply to it.
