What makes people irrational thinkers?

[Belacqua]

He repeatedly describes the materialistic view of matter as inert and incapable of doing more than very simple types of activity. Why he believes that or (if he doesn't believe that) why he writes it, I do not know. In any case, his arguments against materialism fail (as far as I can see) on exactly this point.

Suppose that matter is capable of more types of activity than Hart understands.

How does this show that his arguments about God are incorrect?

I'm wondering if you can construct an argument, based on what Hart says, that if matter is more active than he says it is, his arguments for God fail. But you'd have to do this without begging the question -- that is, it wouldn't be sufficient to argue that of course pretty soon physicalist investigations will be able to answer all the questions they have so far been unable to answer, including why there is something rather than nothing.

To form an argument that's convincing to people who don't already assume he's wrong, you'd have to engage with what he says and show (rather than just assert) that his (allegedly) over-simple view of matter is fatal to his argument.
