Elementary Propositions in Wittgenstein's Tractatus

This is the fourth paper in my continuing research on Wittgenstein’s Tractatus. The Tractatus theory of language has mainly two components: the “picture theory” and the “truth-function theory”. Elementary propositions is one of the basic concepts essentially connected with these two theories. In this paper I attempt a thorough study of the concept of elementary propositions. I identify and articulate seven basic features of elementary propositions. In addition to examining the accounts of other researchers on these basic features, I contribute what I call the metaphysical language formulized in the philosophy of the Tractatus, and the coordinate diagram of elementary propositions, to account for elementary propositions
