It’s not explanation, but James Woodward gave an interventionist account of this concept in physics by building on structural models created by Peter Spirtes. Ernst Mach and Bertrand Russell pioneered challenges to this concept in physics including arguments from vagueness, determinism, non-locality, and time asymmetry. This concept is measured by comparative similarity (15[1])of possible worlds in a (*) counterfactual theory of it by David Lewis. This metaphysical concept (-5[1])is defined as a necessary connection between impressions (10[1])and (10[1])critiqued in a work introducing a problem of induction. That work argues that this concept arises in the mind only due to the constant conjunction of impressions and is by David Hume. For 10 points, name this concept, wherein one event makes another event occur. ■END■ (10[1])
