26. Natural Theory / C. Causation / 5. Direction of causation
People assume events cause what follows them [Aristotle]
     Full Idea: Men take its occurring after as its occurring because.
     From: Aristotle (The Art of Rhetoric [c.350 BCE], 1401b30)
     A reaction: The Latin is 'post hoc propter hoc' - after this so because of this. It is quite a good inductive rule, but obviously open to abuse, as in legal cases, as when someone happens to acquire a lot of money just after a crime.
26. Natural Theory / C. Causation / 8. Particular Causation / e. Probabilistic causation
A cause won't increase the effect frequency if other causes keep interfering [Cartwright,N]
     Full Idea: A cause ought to increase the frequency of the effect, but this fact may not show up in the probabilities if other causes are at work.
     From: Nancy Cartwright (How the Laws of Physics Lie [1983], 1.1)
     A reaction: [She cites Patrick Suppes for this one] Presumably in experimental situations you can weed out the interference, but that threatens to eliminate mere 'probability' entirely.
