“But then there are also many people who would call me arrogant for being dismissive of René Descartes or dismissive of all of Christianity, which also has centuries of thought associated with it.”
Speak of the devil and he doth appear…
It’s never a real fight unless you’re being attacked from both sides!
Let me break down my critique of Descartes, then.
- The ways in which people change over time, especially when the brain is damaged, and the findings of modern neuroscience and cognitive science are pretty much knockdown evidence against dualism.
- Descartes was able to doubt his senses, but not able to properly doubt his own ability to use reason and logic. Insofar as you doubt your senses, you should similarly doubt your own capacity to reason; modern science tells us both of these things are processed by the brain and thus should be treated with a similar degree of skepticism.
- As for the existence of God, it’s pretty obviously wrong as well; just about as obviously wrong as, say, the Flying Spaghetti Monster, Russell’s teapot, or Scientology.
To quote Bertrand Russell:
I ought to call myself an agnostic; but, for all practical purposes, I am an atheist. I do not think the existence of the Christian God any more probable than the existence of the Gods of Olympus or Valhalla. To take another illustration: nobody can prove that there is not between the Earth and Mars a china teapot revolving in an elliptical orbit, but nobody thinks this sufficiently likely to be taken into account in practice. I think the Christian God just as unlikely.
