• Causation
• David Hume's empiricism
• Ideas vs Impressions
• Two kinds of impressions
• Sense impressions
• Impressions coming from introspection
• All our ideas are copied from our impressions
• Cause and effect is a tricky one for David Hume
• What exactly do we see when observing a causal process?
• We don't see any "force" or "power" that causes effects
• Hume says we do experience
• That cause and effect are contiguous in space and time
• Causes occur prior to their effects
• There is a necessary connection between cause and effect
• Cannot have the cause without the effect
• But how do we experience a necessary connection?
• Hume's theory of causation is known as regularity theory
• All theories of causation accept that there are many regularities in the world, and that they have something to do with cause and effect
• Elizabeth Anscombe
• Responded to David Hume's ideas on causation
• Causation doesn't imply necessitation
• It can cause $B$ without necessitating $B$
• Necessity is a logical consequence, relative to the laws of physics
• Not a subjective relation that only exists in our minds
