12 ideas
Can the pineal gland be moved more slowly or quickly by the mind than by animal spirits? [Spinoza on Descartes]
     Full Idea: I am in ignorance whether the pineal gland can be agitated more slowly or more quickly by the mind than by the animal spirits.
     From: comment on René Descartes (Meditations [1641], §6.82) by Baruch de Spinoza - The Ethics V Pref
     A reaction: Is this the earliest statement of the problem of double causation? It is a classic difficulty for dualists, highlighted by Ryle, among others. Avoidance of double causation is a classic reason for moving to monism about mind.
Freedom and natural necessity do not contradict, as they relate to different conditions [Kant]
     Full Idea: Are freedom and natural necessity contradictory in an action? We have shown that freedom can relate to conditions of a kind entirely different from those in natural necessity, so each is independent of the other.
     From: Immanuel Kant (Critique of Pure Reason [1781], B585/A557)
     A reaction: I'm not sure I understand this, but I suspect that it means that a serious case of kleptomania while never provide even the hint of an excuse for a minor theft. We're all free, and that's that. I am dubious.
Can one movement have a mental and physical cause? [Ryle]
     Full Idea: The dogma of the Ghost in the Machine maintains that there exist both minds and bodies; that there are mechanical causes of corporeal movements, and mental causes of corporeal movements.
     From: Gilbert Ryle (The Concept of Mind [1949], I (3))
     A reaction: This nicely identifies the problem of double causation, which can be found in Spinoza (Idea 4862). The dualists have certainly got a problem here, but they can deny a conflict. The initiation of a hand movement is not mechanical at all.
Agency, knowledge, reason, memory, psychology all need mental causes [Kim, by PG]
     Full Idea: The following all require a belief in mental causation: agency (mind causes events), knowledge (perception causes beliefs), reasoning (one belief causes another), memory (events cause ideas), psychology (science of mental causes).
     From: report of Jaegwon Kim (Mind in a Physical World [1998], §2 p.031) by PG - Db (ideas)
     A reaction: A very good list, which I cannot fault, and to which I cannot add. The question is: is there any mental activity left over which does NOT require causation? Candidates are free will, and the contingent character of qualia. I say the answer is, no.
Mind is only interesting if it has causal powers [Kim]
     Full Idea: Unless mental properties have causal powers, there would be little point in worrying about them.
     From: Jaegwon Kim (Philosophy of Mind [1996], p.118)
     A reaction: This doesn't, on its own, actually rule out epiphenomenalism, but it does show why it barely qualifies as a serious theory. One might, in fact, say that we simply can't worry about something which has no causal powers. The powers might not be physical…
Experiment requires mental causation [Kim]
     Full Idea: Experimentation presupposes mental-to-physical causation and is impossible without it.
     From: Jaegwon Kim (Philosophy of Mind [1996], p.128)
     A reaction: So an epiphenomenalist can't do experiments? Kim implies that there is some special mental assessment of the feedback from physical events, but presumably a robot or a zombie could do experiments. Spiders do experiments.
Beliefs cause other beliefs [Kim]
     Full Idea: A brief reflection makes it evident that most of our beliefs are generated by other beliefs we hold, and "generation" here could only mean causal generation.
     From: Jaegwon Kim (Philosophy of Mind [1996], p.128)
     A reaction: This seems right, and yet implies an uncomfortable determinism, as if all our beliefs just happened to us. I don't claim proper free will, but I do say there is an element in belief formation which is just caused by bunches of beliefs. Call it character.
We try to cause other things to occur by causing mental events to occur [Perry]
     Full Idea: We try to cause other things to occur by causing mental events to occur.
     From: John Perry (Knowledge, Possibility and Consciousness [2001], §2.4)
     A reaction: A small and obvious, but important, point. Mental causation isn't just thoughts leading to physical happenings. Here Perry means that events can be designed to cause thoughts, such as a threatening letter. Not much room for epiphenomenalism here.
Maybe mind and body do overdetermine acts, but are linked (for some reason) [Papineau]
     Full Idea: Maybe physical effects of mental causes are always overdetermined by distinct causes (the 'belt and braces' view). Defenders say the two are still counterfactually dependent - but that would raise the question of why, if they are ontologically distinct.
     From: David Papineau (Thinking about Consciousness [2002], 1.5)
     A reaction: [He cites D.H. Mellor as defending 'belt and braces'] This strikes me as the sort of theory that arises from desperation: traditional dualism won't work, but we MUST keep mind separate, so that we can have free will, and save morality. All very confused!
Causation depends on intrinsic properties [Mellor/Crane]
     Full Idea: The problem thoughts pose for causation is that causation depends directly only on intrinsic properties, whereas the causal powers of token thoughts depend on their contents, which are not intrinsic.
     From: DH Mellor / T Crane (There is no question of physicalism [1990], p.194)
     A reaction: This, as we find later in the paper, depends on an externalist account of thoughts. Could a relational property not be causal? Edinburgh's being wetter than London is caused by its being further north?
In the 17th century a collisionlike view of causation made mental causation implausible [Flanagan]
     Full Idea: In the seventeenth century the dominant idea that causation is collisionlike made mental causation almost impossible to envision.
     From: Owen Flanagan (The Problem of the Soul [2002], p.136)
     A reaction: Interesting. This makes Descartes' interaction theory look rather bold, and Leibniz's and Malebranche's rejection of it understandable. Personally I still think of causation as collisionlike, except that the collisions are of very very tiny objects.
If minds are realised materially, it looks as if the material laws will pre-empt any causal role for mind [Heil]
     Full Idea: If a mental property is realised by a material property, then it looks as though its material realiser pre-empts any causal contribution on the part of the realised mental property.
     From: John Heil (Philosophy of Mind [1998], Ch.6)
     A reaction: This has a beautiful simplicity about it. I can see how some very odd phenomena might suddenly appear out of a physical combination, but not how entirely new causal laws can be created.
