7. Existence / A. Nature of Existence / 6. Criterion for Existence
To be is to have causal powers
     Full Idea: To be is to have causal powers.
     From: Samuel Alexander (works [1927], §4), quoted by Jaegwon Kim - Nonreductivist troubles with ment.causation
     A reaction: This is sometimes called Alexander's Principle. It is first found in Plato, and is popular with physicalists, but there are problem cases... A thing needs to exist in order to have causal powers. To exist is more than to be perceived.
17. Mind and Body / A. Mind-Body Dualism / 6. Epiphenomenalism
Epiphenomenalism makes the mind totally pointless
     Full Idea: Epiphenomenalism supposes something to exist in nature which has nothing to do and no purpose to serve.
     From: Samuel Alexander (works [1927]), quoted by Jaegwon Kim - Philosophy of Mind p.129
     A reaction: An objection, but not, I think, a strong one. The fact, for example, that sweat is shiny is the result of good evolutionary reasons, but I cannot think of any purpose which it serves. All events which are purposeful are likely to have side-effects.
Epiphenomenalism is like a pointless nobleman, kept for show, but soon to be abolished
     Full Idea: Epiphenomenalism supposes something to exist in nature which has nothing to do, no purpose to serve, a species of noblesse which depends on the work of its inferiors, but is kept for show and might as well, and undoubtedly would in time be abolished.
     From: Samuel Alexander (Space, Time and Deity (2 vols) [1927], 2:8), quoted by Jaegwon Kim - Nonreductivist troubles with ment.causation IV
     A reaction: Wonderful! Kim quotes this, and labels the implicit slogan (to be real is to have causal powers) 'Alexander's Dictum'. All the examples given of epiphenomena are only causally inert within a defined system, but they act causally outside the system.
