Single Idea 5171

[filed under theme 17. Mind and Body / A. Mind-Body Dualism / 8. Dualism of Mind Critique ]

Full Idea

The problems of bridging the 'gulf' between mind and matter, in knowledge or in action, are all fictitious problems arising out of the senseless metaphysical conception of mind and matter as 'substances'.

Gist of Idea

The supposed 'gulf' between mind and matter is based on the senseless concept of 'substances'

Source

A.J. Ayer (Language,Truth and Logic [1936], Ch.7)

Book Ref

Ayer,A.J.: 'Language, Truth and Logic' [Penguin 1974], p.164

A Reaction

He is presumably implying that there is only one 'substance', the stuff of physics, thus voting for Spinoza's dual aspect theory. There could still be a 'gulf', between incommensurable properties, or untranslatable levels of description.

5326 Qualia must be united by a subject, because they lead to concepts and judgements [Ayer]
5324 Bodily identity and memory work together to establish personal identity [Ayer]
5327 Temporal gaps in the consciousness of a spirit could not be bridged by memories [Ayer]
5329 Why shouldn't we say brain depends on mind? Better explanation! [Ayer]

2611 It is currently held that quantifying over something implies belief in its existence [Ayer]
2610 Talk of propositions is just shorthand for talking about equivalent sentences [Ayer]
5661 We identify experiences by their owners, so we can't define owners by their experiences [Ayer]
