Abstract
One of the most frequently discussed notions in Wittgenstein’s Tractatus is the notion of simple object. However, among the literature on Tractarian objects, recent or classic, none has treated configurations of objects as a major and non-trivial issue. In this paper, I show that a detailed study of configurations of objects will yield a series of interesting and important results: it leads to a new understanding of the picture theory, helps us calculate the maximum numbers of internal and external properties of objects, and enables us to reinterpret and reach a solution to the notorious debate on whether properties and relations should be included as Tractarian objects.
