Thomas Aquinas

uh-KWY-nuhs
Metaphysics

Thomas Aquinas (circa 1225 to 1274) is the central figure of Scholasticism, the medieval method that reconciled Aristotelian logic with the intellectual life of the new universities. His Five Ways offer cosmological arguments for a first cause, arguing that an endless chain of causes is impossible. His natural law theory grounds moral reasoning in the self-evident principle that the good should be done and pursued and the bad avoided, discovered by reason reflecting on human inclinations toward flourishing.

Quote, Associated With: Natural Law Theory, Section 1.1.1, Why natural law? Naturalistic fallacy?
Aquinas is particularly clear and explicit that in this context, 'natural' is predicated of something (say, a law, or a virtue) only when and because that of which it is predicated is in line with reason.
