Those who naturalize semantics concentrate on avoiding difficulties in getting the right sort of cause for the biological item which is to possess semantic properties (to be ?true of or to be ?about? some physical item). Using an analogy with sense?data, I argue that the real difficulties will be trying to get any proposed neural representation to be the right sort of effect of natural processes. The idea of a biological item which can be a semantic ?primitive? is as bankrupt (...) as the idea of a mental item which could be a perceptual ?primitive?. Eventually I propose a technique for finding naturalized representations without these problems. (shrink)

A new story is abroad that plato possessed two redundant devices in the "phaedo" to explain why some sensible "f" (a drift of snow, say) is "g" but never not-"g" (cold, say): (i) "f" participates in a special way in the (upper world) forms "f" and "g"; (ii) "f" is essentially "g" in its own (lower world) right. Were there such genuinely redundant devices, this would tidily explain both plato's coming to reject essential properties for sensibles in the "republic" and (...) aristotle's coming to reject forms for sensibles in the "categories". Now it is true in the "phaedo" that sensible "f" particulars can indeed by "g" and never not-"g", yet no redundant "essentialist" doctrine occurs there. Plato's reasoning is through and through form-ist: an "f" particular has a "participation" relation to the form "f", which form "f" has an "invariable accompaniment" relation to the form "g", which form "g" can never itself be not-"g"; the form "g"'s own never-not-"g" constraints thence get percolated back down the line of these canonical two worlds relations, by a still little-noticed "back-passing principle.".
