Hume's philosophy of causality

David Hume's philosophy of causality suggests that we cannot perceive causal connections directly; instead, we only observe a sequence of events. For example, when we see a ball hit another and the second ball move, we associate the first event with causing the second. Hume argued that our belief in causation stems from habit and experience, not rational proof. This challenges traditional views of laws of nature, suggesting they are not absolute truths but rather patterns we’ve observed repeatedly, leading us to expect certain outcomes based on past experiences, rather than inherent necessities in nature itself.
