Fact and Utterance

According to #2.141 of the Tractatus, "The picture is a fact."  So, since Wittgenstein classifies the Proposition as a Picture, a Proposition is a Fact, in this scheme.  Now, while a written sentence, like a painting, survives the process that first produces it, an oral utterance is no more separable from the uttering of it than a sneeze is from the expulsion of it.  In other words, an Utterance originates not as a Fact, but as an Element in a Fact, as the Fact-Element relation is conceived in the Tractatus.  Thus, either some Utterances are not Propositions, or else some Propositions are not Facts, a difficulty more easily avoided after the abstraction of 'Language' from the context of Communication.
