I edited my post when I posted it here, and included a final paragraph that outlined four big problems. These are problems that anyone who would - as you say - start in with metaphysics would encounter. One of these problems is what I have called the fourth problem. Might as well be the first problem, number is unimportant. It's about a linguistic or conceptual problem.
I'm a bit influenced here by David Papineau who discussed conceptual dualism in his philosophy of consciousness. Basically, he proposes that we have two different types of concepts - different classes - material concepts and phenomenal concepts, and that these different sorts of concepts are responsible for the 'feeling', the 'idea' that there is something different between the brain and the mind.
Now, I don't want to discuss Papineau here - obviously - but I am influenced by this way of thinking about concepts. I suppose you might call it Ryle's category error, but refined to concepts. I'm saying that causality and purpose, per example, are empirical concepts and that applying them beyond the empirical world - like per example, on the empirical world itself - is without basis.
What Jamest does, I think, is quite intuitive. Because he lives in the empirical world and is used to using causal relationships between everyday things, he applies the same 'causality' detector for the empirical world itself. But, we must ask ourselves, is there any basis for this? Why should we believe that this method that makes accurate predictions in the empirical world can also make predictions about the metaphysical?
Indeed, when we think about, we are immediately puzzled! We can't even test whether causality could be used in that way.. We can't think of any argument. It's obvious that, even if metaphysics is possible, Jamest is on the wrong end. More importantly, most philosophers have thusfar been on this wrong end and have been unable to substantiate this.
As for myself, I have no problem with saying 'something caused this or that' - you want to say it, that's just fine with me. Even philosophically, I feel sympathetic for it, because it is quite intuitive. I just ask 'why be so certain about it'. I think I'll look up Nietzsche and quote him next..
