What is the central tension in David Hume’s philosophy regarding knowledge and belief?

• A. The nature of space and time
• B. Skepticism about causation and miracles
• C. Certainty about the external world
• D. The existence of God

Answer: (B)

The main idea here is how we justify our beliefs about cause and effect, and what that does to our confidence in knowing the world. David Hume argues that our understanding of causation comes from habit and experience, not from any logical necessity. We observe that certain events tend to follow others, so we come to expect a connection. But this expectation isn’t a result of rational proof that a necessary link must exist; it’s a psychological pattern we develop from repeated experience. That leaves a tension: our beliefs about how things cause one another feel firm, yet they aren’t backed by solid deductive justification.

Hume pushes this further with miracles, arguing that extraordinary reports contradict the uniform experience we rely on to judge natural law. Since the weight of evidence for regular patterns in nature far exceeds the testimony for rare, miraculous events, trusting such miracles undermines the very basis of what we claim to know from experience. In short, knowledge about the world rests on causal inferences that lack rational certainty, and miracles highlight how fragile that foundation can be.

The other options miss this core issue. The discussion isn’t primarily about space and time, nor is it about asserting absolute certainty about an external world as a settled fact, and while God’s existence enters Hume’s critiques, the central epistemic tension he foregrounds is how we justify causal beliefs and handle miraculous testimony.
