He's a Platonist, so he believes in the existence of a real world that is neither material nor mental. His central claim that conscious acts are in some sense noncomputational is prima facie false. And his concrete solution to problem collects together several other very difficult problems and essentially says, solve one, solve them all. (Great news for his publishers btw.) For those reasons, it's hard to take seriously because it's outrageously speculative.
