Mr. Wittgenstein begins his theory of Symbolism with the statement ( 2.1 ): “We make to ourselves pictures of facts.” A picture, he says, is a model of the reality, and to the objects in the reality correspond the elements of the picture: the picture itself is a fact. The fact that things have a certain relation to each other is represented by the fact that in the picture its elements have a certain relation to one another. “In the picture and the pictured there must be something identical in order that the one can be a picture of the other at all. What the picture must have in common with reality in order to be able to represent it after its manner⁠—rightly or falsely⁠—is its form of representation” ( 2.161 , 2.17 ).
