Permenides a Logical Atomist??

So Tilghman in Parmenides, Plato, and Logical Atomism tries to bring Parmenides theory within the context of Russell's theory of descriptions and language. He says that Parmenides had both a theory of meaning for words and sentences. His theory of meaning basically states that

"the meaning of an expression is what it names or denotes. If an expression does not denote anything it is meaningless, hence no expression apparently denoting a non-existent somewhat, "that which is-not," can be intelligible." p.153

This theory of meaning is central to his philosophy in that words are names and sentences are states of affairs. By applying this sentence meaning though it makes it harder for Parminedes to argue that the world is unchanging and homogeneous. Also embedded in each statement about change is a non-existent state of affair such as referring to the past in the statement "Jones is now fat." Implying both that Jones is now fat, but that at a certain time in the past fatness did not exist.

Tilghman's solution is to add a theory of prediction to Parminedes theory of meaning. So if we can talk about the various possibilities it allows us to discuss non-existent states of affairs. This seems to sum it up quite nicely for him, but I would have to disagree. He falls into an existential slum because everything is "equally meaningless" thus is homogeneous. Weird.
