How did David Hume challenge arguments for the existence of God?

The Scottish philosopher David Hume challenged traditional arguments for the existence of God primarily through his work in the Enquiry Concerning Human Understanding and his posthumous Dialogues Concerning Natural Religion. His critique focused on two main areas:1

• The Argument from Design: Hume attacked the popular 18th-century teleological argument, which inferred a divine designer from the apparent order of the universe. He argued that the universe and its supposed cause are unique and incomparable, making it impossible to apply experience-based reasoning to them. He further suggested that observed order could result from chance permutations of particles rather than deliberate design. Even if a designer were inferred, Hume argued one could not logically conclude that this being possesses the infinite power and goodness attributed to the God of traditional theism, as the world contains significant imperfection and suffering.231
• Miracles and Revelation: Hume argued that miracles, often cited as evidence for divine revelation, are highly improbable given the uniformity of nature. He maintained that a wise person must proportion their belief to the evidence, and historical accounts of miracles fail to provide a reliable foundation for religious systems.41

By emphasizing the limits of human knowledge, Hume’s skeptical approach effectively challenged the standard framework of Christian apologetics of his time.1
