Dialogues Concerning Natural Religion

David Hume 1779

Three speakers debate what nature can tell us about God in a series of philosophical conversations. Cleanthes compares the world to a machine, while Philo questions whether that comparison proves a divine designer.

  • One of the most important works ever written on whether reason and evidence can prove that God exists.
  • Argues that the order we see in nature is too weak a clue to tell us much about its maker, who could just as well be flawed, careless, or one of many gods.
  • Asks how a good and all-powerful God could allow so much pain and suffering, and suggests the world looks more like it was made by a force that does not care.
  • Its attack on the "design argument" (the idea that a well-ordered world must have a wise designer) is still the starting point for nearly every serious debate on that question.
  • Shaped later thinkers such as Immanuel Kant, who also concluded that reason alone cannot prove God, and it remains standard reading in philosophy of religion courses.

  • Published only after his death

    Hume held the book back for over twenty years and arranged for it to appear after he died.

  • Friends urged him to hide it

    Friends, including Adam Smith, warned that publishing it would cause a scandal and harm his name.

  • Revised on his deathbed

    Hume was still making changes to the manuscript in 1776, during the final months of his life.

  • Printer's name left off

    The first edition gave no publisher's name, likely to protect those involved from religious anger.
