Here is a clip of Sam Harris presenting one of the standard arguments against dualism -- namely, that physical damage to the brain is known to affect practically every function of consciousness, so therefore we have good reason to view consciousness as inseparable from (and probably originating in) the brain.
The argument obviously poses a problem for religions that teach eternalism -- i.e. that there is some sort of permanent soul which leaves the body at death and goes to heaven, limbo or hell, or into a new body. My question: is it also a problem for Buddhism?
Yes, it poses a problem
Buddhism teaches that consciousness is one of five aggregates. If consciousness originates in the brain then it is really just a byproduct of the form aggregate. Indeed, so are the remaining three (sensation, perception, formations). Moreover, the Buddha clearly taught that the mind is capable of entering "formless states" which would be impossible unless it can operate independently of the brain.
No, it does not pose a problem
Buddhism doesn't teach eternalism. Instead, it posits an ongoing process of dependent origination. Even if Harris is correct, there is no logical objection to the process of consciousness arising again and again, driven by karma. Buddhadharma can therefore neither be classified as materialism nor Cartesian (substance) dualism. It is perhaps closer to property dualism.
The formless realms remain problematic, but a) they are a holdover from the sravaka movement, and b) they are not essential. Indeed, from the Buddhist point of view one wants to avoid these realms because no progress can be made while in them.
Buddhism teaches that a given mindstream (rearising via D.O.) can transmigrate into the animal realm, where there is a loss of cognitive functionality as well. Therefore, the argument from brain damage is already anticipated.
How would you respond to Harris?
