The Moral Noetic of the Natural Law

Law: the word, to many, conjures images of the courtroom or a legislature—ponderous tomes of tediously-written jargon rendering a complex web of oft-arbitrary-seeming stipulations and impingements.  So prevalent is this imagery that to speak of the “natural law” sounds often like a mere metaphor.  Exacerbating this “metaphorical” tenor of the phrase has been its use in ideological battles.  Sometimes it is made a shield against criticism; other times, a sword to cut down proposals.  But again and again, as history well shows, return to the notion is made, and not coincidentally when threat is made to the coherence of “nature” as normative in human experience.

The revival of interest in natural law in our own time is certainly related to the devastations wrought by positivism and existentialism in the intellectual and political life of a considerable part of Western society, which it is generally agreed is undergoing rapid and radical transformations.  By our own example, then, we realize how the theory of natural law may be influenced by the aspirations of a society, at a certain moment of its evolution, and how great is the danger for that theory of becoming nothing more than an expression of these aspirations.

Simon 1965: The Tradition of Natural Law: A Philosopher’s Reflections, 27.

Rather than capitulate theory of the natural law to these “aspirations of a society”, one ought instead to understand what that law is.  Perhaps most poignantly, we need to understand how that law is known.  How do we discover the first principles of the natural law?  How do these principles inform our moral reasoning?  Join us for this 8-week seminar, led by Dr. Matthew Minerd, to investigate these and other related questions.  Deadline for registration is 5 July 2023.
