Abstract

The philosophies of late Brentano and early Wittgenstein can be brought closer in two ways. One way discovers a surprising amount of part-whole theory in the Tractatus if we see states of affairs (not wholly wilfully) as thinglike rather than factlike. This throws up a modal analogue to Chisholm's entia successiva in the form of situations. The other way sees all propositions as truth-functions of existential propositions, supporting Brentano's view that existentials are primary, and incidentally yielding a reistic semantics for the Tractatus. I draw a quick moral, that we should beware of excessive simplicity in metaphysics, and apply it to Chisholm's views on part and whole.
