I actually phrased that statement that way to avoid and speculation about what might be possible, as it would be a distraction from the point I am making. As it happens, I think it is probable that such a model is possible in principle, and also that a complete model would not be understandable (in which case, Bonnini's paradox would apply, but it is not the reason why we currently don't have such a model). With regard to cognitive closure, I think the first sentence of the article you link to is trivially true, but I have yet to find a good argument against physicalism in matters of the mind, and philosophers cannot agree among themselves. I think it is interesting how little attention is said about biology in these arguments (Paul Churchland is one exception.)
