| 2364 | Causation is only observation of similar events following each other, with nothing visible in between [Hobbes] |
| Full Idea: In knowing the meaning of 'causing', men can only observe and remember what they have seen to precede the like effect at some other time, without seeing between the antecedent and subsequent event any dependence or connexion at all. | |
| From: Thomas Hobbes (Leviathan [1651], 1.12) |
| 8608 | Counterfactuals 'backtrack' if a different present implies a different past [Lewis] |
| Full Idea: A counterfactual can be said to 'backtrack' if it can be said that if the present were different a different past would have led up to it (rather than if the present were different, the same past would have had a different outcome). | |
| From: David Lewis (New work for a theory of universals [1983], 'Dup,Sup,Div') | |
| A reaction: A nice clear definition of a concept which is important in Lewis's analysis of causation. In the current context he is concerned with elucidation of determinism and materialism. I would say (intuitively) that all counterfactuals backtrack. |
| 8584 | Causal counterfactuals must avoid backtracking, to avoid epiphenomena and preemption [Lewis] |
| Full Idea: My counterfactual analysis of causation needs counterfactuals that avoid backtracking; else the analysis faces fatal counterexamples involving epiphenomenal side-effects or cases of causal preemption. | |
| From: David Lewis (New work for a theory of universals [1983], 'Laws and C') | |
| A reaction: The concept of true epiphenomena (absolutely no causal powers) strikes me as bogus. |
