Constant conjunction is a philosophical concept associated with the work of empiricist philosopher David Hume. It refers to the idea that our understanding of causation is based on the observation of events that consistently occur together. In other words, when we see one event (the cause) consistently followed by another event (the effect), we come to associate the two and infer a causal relationship between them.
