Christian theologian and philosopher St. Augustine of Hippo once wrote “lex iniusta non est lex”, which his Latin for “an unjust law is no law at all”. This idea is one of the fundamental tenets of natural law theory and has been echoed not only by other theologians such as Thomas Aquinas, but frequently in philosophical, legal and civic discourse.

Even still, there is an ongoing debate about discrimination based on capacity that Hart brushes
