Thesis Anscombe was right: we see causing all the time
Where it stands
I make cedar doors and ceilings in Tetouan. When I push a chisel through cedar I do not see a chisel, then a cut, and infer a connection. I see the chisel cutting. When my apprentice drops a plank and it cracks, he does not observe two events and form a habit. He sees the plank crack because it was dropped.
Hume said we never see necessary connection, only one thing following another. Elizabeth Anscombe, in her lecture "Causality and Determination" (1971), replied that we learn causal concepts through countless ordinary verbs, scrape, push, carry, burn and many more. To see someone pushing a cart is already to see causing. The general word "cause" is an abstraction from these specific ones, not a mysterious extra that observation has to find.
I think she is right, and that Hume was misled by thinking of perception as a series of separate pictures. Craftsmen don't perceive like that. Neither do children learning to play.
Anscombe also argued that causation need not mean necessitation: a cause can bring something about without its effect being guaranteed. That fits my workshop too. The same stroke sometimes splits the wood.
I am not a philosopher, so tell me where this goes wrong.
