2.131 In a picture, the elements of the picture stand in for objects.

Again, more literally: The elements of a picture stand [in], in the picture, for objects. So objects now seem to be the kind of things that can be represented, which sounds metaphysical again. This, we might say, is the problem of language. It is hard to talk about something without making it sound like a thing, an object, a res. How can the elements of a picture stand for possibility spaces? Well, in a graph the points on the coordinates do. In a painting or sentence ..., what? Every possible content is represented by every possible content. And what are the contents of a sentence? Clauses, words, letters, letter-parts? It's hard to see how there can be a right answer.
