The brain reflects everything in the physical world. To completely understand it, we'd have to understand everything in the physical world and then there'd have to be no new things. But there are always new things just as a matter of course. People won't understand my argument because it's basically the same fundamental argument as ultrafinitism but it's true. Abstractions are not real. Abstract means "to take away." But you have to take away from something. If you take away everything, there's nothing left.
