Abstract
That Wittgenstein in the Tractatus likens logic to geometry has been noticed; however, the extent and force of the analogy he develops between logical form and a broadly Kantian account of geometry has not been sufficiently appreciated. In this paper, I trace Wittgenstein's analogy in detail by looking closely at the relevant texts. I then suggest that we regard the fact that Wittgenstein develops his account of logical form by analogy with a Kantian account of geometry as evidence for the bold thesis that Wittgenstein belongs within a Kantian epistemological tradition. Finally, I supply two small pieces of the interpretive puzzle needed to support the larger thesis: first, evidence that Wittgenstein's concern with logical form involves a crucial epistemological component; second, a sketch of how Wittgenstein's account of logical and mathematical knowledge can be viewed as continuing a Kantian tradition.
