13 ideas
T.H.Huxley gave the earliest clear statement of epiphenomenalism [Huxley, by Rey]
     Full Idea: T.H.Huxley gave the earliest clear statement of epiphenomenalism.
     From: report of T.H. Huxley (Method and Results [1893]) by Georges Rey - Contemporary Philosophy of Mind 3.1.1
     A reaction: This is, of course, impossible, because there can't be a clear statement of epiphenomenalism.
Brain causes mind, but it doesn't seem that mind causes actions [Huxley]
     Full Idea: All states of consciousness are caused by molecular changes of brain substance. It seems to me there is no proof that any state of consciousness is the cause of change in the motion of the matter of the organism.
     From: T.H. Huxley (Method and Results [1893], p.244), quoted by Georges Rey - Contemporary Philosophy of Mind 3.1.1
     A reaction: This sounds odd. Most people would say there is nothing more obvious than mental events causing actions. It certainly seems undeniable that actions are cause by the contents of thoughts, so a molecular account of intentional states is needed.
Consciousness is a terminal phenomenon, and causes nothing [Nietzsche]
     Full Idea: Everything of which we become conscious is a terminal phenomenon, an end - and causes nothing.
     From: Friedrich Nietzsche (The Will to Power (notebooks) [1888], §478)
     A reaction: This appears to endorse epiphenomenalism - which I take to be an incoherent concept. How can becoming fully aware of something, rather than subliminally or subconsciously aware, make no difference at all? If it exists, it has causal powers.
Epiphenomenalism is like a pointless nobleman, kept for show, but soon to be abolished [Alexander,S]
     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.
Epiphenomenalism makes the mind totally pointless [Alexander,S]
     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.
If epiphenomenalism were true, we couldn't report consciousness [Kim]
     Full Idea: If epiphenomenalism were true, it would be a mystery how such things could be known to us.
     From: Jaegwon Kim (Philosophy of Mind [1996], p.130)
     A reaction: If a brain were asked whether it was conscious, it would presumably say 'yes', but (if epiphenomenalism were true) the cause of that would have to be brain events, and NOT information that it is conscious, which the brain could not have. Big objection.
If epiphenomenalism just says mental events are effects but not causes, it is consistent with physicalism [Perry]
     Full Idea: Epiphenomenalism is usually considered to be a form of dualism, but if we define it as the doctrine that conscious events are effects but not causes, it appears to be consistent with physicalism.
     From: John Perry (Knowledge, Possibility and Consciousness [2001], §4.2)
     A reaction: Interesting. The theory was invented to put mind outside physics, and make the closure of physics possible. However, being capable of causing things seems to be a necessary condition for physical objects. An effect in one domain is a cause in another.
If an epiphenomenon has no physical effects, it has to be undetectable [Dennett]
     Full Idea: Psychologists mean a by-product by an 'epiphenomenon', ...but the philosophical meaning is too strong: it yields a concept of no utility whatsoever. Since x has no physical effects (according to the definition), no instrument can detect it.
     From: Daniel C. Dennett (Consciousness Explained [1991], 12.5)
     A reaction: Well said! This has always been my half-formulated intuition about the claim that the mind (or anything) might be totally epiphenomenal. All a thing such as the reflection on a lake can be is irrelevant to the functioning of that specified system.
Either intentionality causes things, or epiphenomenalism is true [Fodor]
     Full Idea: The avoidance of epiphenomenalism requires making it plausible that intentional properties can meet sufficient conditions for causal responsibility.
     From: Jerry A. Fodor (Making Mind Matter More [1989], p.154)
     A reaction: A wordy way of saying we either have epiphenomenalism, or the mind had better do something - and a good theory will show how. The biggest problem of the mind may not be Chalmer's Hard Question (qualia), but how thought-contents cause things.
The epiphenomenal relation of mind and brain is a 'causal dangler', unlike anything else [Papineau]
     Full Idea: If epiphenomenalism were true, then the relation between mind and brain would be like nothing else in nature. After all, science recognises no other examples of 'causal danglers', ontologically independent states with causes but no effects.
     From: David Papineau (Thinking about Consciousness [2002], 1.4)
     A reaction: This would be a good enough reason for me to reject the epiphenomenalist view, even if I thought it was a coherent proposal. Insofar as it proposes the existence of something (mind) with no causal powers at all, it strikes me as nonsense.
Maybe minds do not cause actions, but do cause us to report our decisions [Papineau]
     Full Idea: Even if conscious decisions did not contribute causally to the actions normally attributed to them, they would still presumably be the causes of the sounds I make when I later report my earlier conscious decisions.
     From: David Papineau (Thinking about Consciousness [2002], 1.4)
     A reaction: This is a good reply to my view (borrowed from Dennett - Idea 7379), that epiphenomalism proposes an absurdity (an entity with no causal powers). But if mind can cause speech, why could it not cause arm movements?
Functionalism defines mental states by their causal properties, which rules out epiphenomenalism [Crane]
     Full Idea: Functionalism holds that it is in the nature of certain mental states to have certain effects; therefore there can be no mental epiphenomena.
     From: Tim Crane (Elements of Mind [2001], 2.14)
     A reaction: I strongly resist the idea that a thing's identity is its function. Functionalism may not say that. Mind is an abstraction referring to a causal nexus of unknowable components.
If qualia are causally inert, how can we even know about them? [Lowe]
     Full Idea: The idea that 'qualia' exist but are causally inert is difficult to sustain: for if they are causally inert, how can we even know about them?
     From: E.J. Lowe (Introduction to the Philosophy of Mind [2000], Ch. 3)
     A reaction: The brain might be a special case. I can't know about a 'causally inert' object in my kitchen, but I might know about it if in some way I AM that object. Personally, though, I think everything that exists is causally active.
