Emanuel Rutten sent me the following interesting argument which I am posting with his permission. Please make sure to be clear that if you cite this post, everything except the title, the preceding sentence and this sentence, is taken verbatim from Rutten. He has some other interesting arguments on his blog, some of which alas are in Dutch.
Take the following metaphysical principle, connecting possible worlds, knowledge and truth: ‘If it is impossible to know that p, then p is necessarily false’. This principle seems cogent. For, if a given proposition p could be true, then, plausibly, there is some possible world in which some subject knows that p is true. In other words, if in *all* possible worlds *all* subjects do not know that some proposition is true, then, plausibly, that is because that very proposition cannot in fact be true.
Well, on a Cartesian view of knowledge, that is, to know p is to be certain that p is true, the above principle has an interesting consequence. For, take for p the proposition ‘God does not exist’. It seems reasonable to hold that it is impossible to know that God does not exist. For, whatever the arguments against God, there will always be some (perhaps an extremely remote) possibility that God does exist after all, so that we can never truly say, on the Cartesian view, that we know that God does not exist. But then it follows that it is necessarily false that God does not exist. Hence, it is necessarily true that God exists. The principle thus entails theism. Is this new argument for theism convincing?
For his essay, “Grounding and Omniscience.” Dennis will be presenting this paper in an invited session on Philosophical Theology at the Pacific Meeting next spring in San Diego (I’ll also be presenting at the same session).
The finalists for the prize, whose papers will also be published in OSPR, are (in alphabetical order):
Shieva Kleinschmidt, “Many-One Identity and the Trinity”
Christian Miller, “Error Theory and Theism Revisited”
Meghan Sullivan, “Semantics for Blasphemy”
Congratulations to all concerned!
