Originally published posthumouly in 1779, David Hume’s Dialogues Concerning Natural Theology sounded the death knell for natural theology. Natural theology was the attempt to discern the character and existence of God from creation alone, apart from revelation. Addressing arguments from the appearance of design in the world (a posteriori), what is now called the cosmological arguement (a priori), and the moral argument, Hume describes in an engaging manner the interactions of an ‘orthodox’ Christian, Demea (who is really a Christian mystic); a deist, Cleanthes; and a empircal skeptic, Philo. Though the dialogues seem to favour Cleanthes as Hume’s representative, Philo throughout best represents Hume’s thought and is consistently given the upper hand in the dialogues: it is in Philo, then, that we should seek Hume’s voice. Speaking through Philo, Hume concludes that everyone must concede that the first cause of the universe bears some remote resemblance to man, yet that this not so very different from atheism and such a concession, apart from revelation, cannot be further explained and can have no effect on the way a person lives his life–it is a practically meaningless concession. In light of his rejection elsewhere of the possibility of revelation, we see here in Philo the intent of Hume’s book: thinly disguised by the concluding paragraph, Philo intends the reader to conclude with him that God is not clear in creation and that any first cause we attribute to the universe is nothing like the Christian God–it would be unknowable, probably evil, and unable affect the lives of anyone.
Apart from revelation, then, Hume’s book is a devestating critique of religion–a critique that is strikingly relevant today, parroted often by the New Atheists. Yet we don’t live in world without revelation: God has made Himself abundantly clear in creation, so much so that all are held accountable, and has revealed Himself from the beginning of His creation verbally to His creatures. Humes argument is a devestating critque of religion that would start with man as the ultimate reference point for meaning, that would make man’s autonomous reason the measure of God’s existence and attributes. In so doing, Hume’s book is a valuable read for the biblically saturated Christian today. He shows that to begin with man’s autonomous reason is to end up without God, but God has never left it up to our autonomous reason: in making us in His image, we have been born with the interpretive tools necessary to accurately discern His invisible attributes in His creation (Rom. 1:18ff): it is only in our unrighteousness that we suppress this knowledge and attempt to work on the foundation of our finite reason alone. More than this, God has also revealed Himself clearly in His Scriptures: the Bible testifies to the fullness of His character as man in this life can know Him and His work. When one begins with Scripture, Hume’s arguments appear hollow.
To aid the interested reader in better understanding Hume’s argument, I have provided below an outline of Hume’s Dialogues summarizing each part of the book and with it a shorter outline .
