If dualism is true, then mind is not spatio-temporal, and body is spatio-temporal. — quine
Such a thought is called 'epiphenomenalism'. Epiphenomenalism is a kind of dualism. Many philosophers reject epiphenomenalism. — quine
I have long been in agreement with this argument.
Descartes was aware of the problem: If mind and body are entirely incommensurate, how can mind make the body do things? His solution was the quite unsatisfactory notion that "god did it".
Dualism fails. — Banno
I don't think it fair to say that dualism fails because it hasn't explained how the mind and the body interact. There are a lot of things that physics hasn't explained (which is why we don't have a theory of everything) but it doesn't then follow that it's fair to say that physicalism fails for this reason.
That would be an argument from ignorance. — Michael
1. If physicalism is true, then physical matter produces the mind and consciousness.
2. It is not the case that physical matter produces the mind and consciousness.
Therefore:
3. Physicalism is false. — Chany
(1) If dualism is true, then mind is not spatio-temporal, and body is spatio-temporal.
(2) If mind is not spatio-temporal, and body is spatio-temporal, then mind and body cannot interact. — quine
Does a dualist have to believe that nonphysical existents are not spatio-temporal? — Terrapin Station
Descartes says that the essence of mind is thinking. He claims that the essential feature of body is extension. It implies that Descartes thinks that mind is beyond space and time. Anything beyond space and time cannot interact with something in space and time. — quine
According to Cartesian dualism, the mind is a non-spatial thing, so we can grant quine the first premise. — Michael
Get involved in philosophical discussions about knowledge, truth, language, consciousness, science, politics, religion, logic and mathematics, art, history, and lots more. No ads, no clutter, and very little agreement — just fascinating conversations.
