Natural theology

Can anything be known about God by reason alone? Natural theology is the study of God without appeal to revelation. These readings ask what the unaided mind can say about the divine, and where its power stops.

Book X of Plato’s Laws opens its treatment of impiety with this speech, in which the Athenian Stranger and his two companions turn to the “Gods” as the ground of the whole code. He speaks of a “prelude” to the laws and undertakes a “demonstration”. The dialogue is Plato’s last and longest, and this passage is cited as an early case of argument about the divine as a part of lawmaking. It sits under natural theology as the proposal to prove the gods by reason.

In Book XI of the Metaphysics, part 7, Aristotle is marking out the “theoretical sciences” and asking how a science of “being qua being” stands to “physics” and “mathematics”. He names “theology” as the third, concerned with what is “separable and unmovable”. The treatise is the main source of the term in its philosophical use, and the Scholastics took the division from it. It stands under natural theology as the place where theology is first reckoned a science.

In Book VI of the City of God, Augustine reports the scholar Marcus Terentius Varro’s division of theology into three kinds, the fabulous, the natural (“physical”) and the civil, and here takes up the second kind, that of the philosophers. He is arguing against the claim that the pagan gods are to be worshipped for the sake of eternal life. The City of God was written after the sack of Rome in 410. It sits under natural theology as a record of how the philosophers’ “theology” was distinguished from the theology of the poets and the city.

This is from the Transcendental Dialectic of the Critique of Pure Reason, in the section on the impossibility of a speculative theology. Kant distinguishes “theologia rationalis” from “theologia revelata”, and within the first “transcendental theology” from “natural theology”, and defines the “deist” and the “theist”. The Critique of 1781 set the terms in which later philosophy of religion has been argued. It sits under natural theology as a classification of what reason alone might claim about a supreme being.
