Tractarian Scaffoldings

In the Tractatus Wittgenstein often uses graphic metaphors: a ladder, which is to be thrown away after it has been climbed; pictures with feelers; networks with fine square meshes. Although they are illuminating, it is not always clear in exactly what sense Wittgenstein employs them. In this paper, we will try to eliminate this fuzziness with respect to the concept of scaffolding (Gerüst).
