Most readers of the Tractatus take Wittgenstein's logic to be contentless, since tautologies do not picture reality. However, this fails to explain its transcendental status, especially given that Kant introduced transcendental logic through the notion of content. In this essay, I propose a transcendental interpretation of Wittgenstein’s logic, as "logic of depiction” endowed with a transcendental content: the formal rules governing the subject’s speech about objects. Tautologies turn out to be dispensable by-products of the transcendental (i.e., content-endowed) logic of depiction. (...) The result is a reconception of Wittgenstein's logic, grounded in a systematic comparison with Kant. (shrink)
