[a_humean]

They are very very closely related, and philosophers and Pearl cite each other on the topic of causation, but Hume and philosophers are usually concerned with a slightly different problem. Hume is concerned about the nature of the necessity between any cause and effect which seemed to be implied by our experience of events. Whereas Pearl (much less knowledgeable about Pearl) is interested in how we can model events to give us high confidence in the relation applying in a particular case while leaving the topic of necessity and the fundamental nature of causation to the side and assuming a much more vague /ad hoc notion of what causation is.
