Abstract
I argue that the picture theory provides both a common referential hase and a common logical syntax for languages embodying alternative conceptual schemes. I offer an analysis of depiction, explicating the Tractarian concepts of pictorial structure, pictorial relationship, and representational form. Significant failure of reference and the existence of languages with incompatible ontological commitments show that on the molar level depiction is not required for sense. Using three premises, taken to be axiomatic for Wittgenstein, I show that analysis leads to a base of elementary propositions which must depict in order to be significant. There, the relations between pictorial structure, pictorial relationship and representational form are such that reference is secured and conceptual relativity precluded.
