Wittgenstein's ideas (2.12-2.15) regarding pictures as models of reality immediately made me think of Stevens' "Study of Two Pears." Wittgenstein's ideas are as follows:
2.12 A picture is a model of reality.
2.13 In a picture objects have the elements of the picture corresponding to them.
2.131 In a picture the elements of the picture are the representatives of objects.
2.14 What constitutes a picture is that its elements are related to one another in a determinate way.
2.141 A picture is a fact.
2.15 The fact that the elements of a picture are related to one another in a determinate way represents that things are related to one another in the same way.
Upon analyzing Stevens' poems about pears, it seems that one can never get to the pearness of pears because other details get in the way; one begins to see other aspects (color, shape, form, etc.) with every passing moment, as demonstrated in Stevens' poem. While the painting attempts to show the pearness of pears, in a way, this painting is only successful at doing so with these two particular pears the picture represents. That is not to say that this picture does not represent reality as Wittgenstein claims, but it only represents the reality that once was when these particular two pears served as the model for this painting. However, this reality is no longer. While other pears may share similar elements to the two pears in the painting, they are not identical. According to Wittgenstein, I believe pears are related to each other in a determinate way because of this. The two pears described in the poem are representatives (and representatives only) of the two pears the artist of the painting was painting, to which, I believe is safe to assume, Stevens and Wittgenstein would agree.
