The ontology of the Tractatus is a strictly formal presentation of our language and thinking (of everything intelligible), not metaphysics as a systematic account of the being and the world. According to it, propositions are constructed (4.5), and “a proposition constructs a world” (4.023). Together, these are touchstones of Wittgenstein’s logico-philosophical doctrine which legitimates the reconstruction of Wittgenstein’s constructivist “ontology of ways” that the present chapter undertakes. Neither modal nor tropic in character, Wittgenstein’s “ways” elucidate the forms in which the elements of a basal ontological system can be articulated such as to realize ontological systems of higher order. The advantage of this original ontology is the elegant solution it affords to the problem of constructing ontological systems—such as states of affairs, thinking, language, logic and works of art.
