This article presents a reading of aphorism 6.36111 of Tractatus Logico-Philosophicus by Wittgenstein, from its localization in the critical, wide-reaching, debate on the project of transcendental philosophy. The intention of the article consists of clarifying the historical background suggested by the mention of the?Kantian problem”. This shows that Wittgenstein found in the context of the dispute about spacial representation, that which is not explicity in the aphorism, some arguments to reject the key concept of Kant’s theoretic philosophy: the ideality of (...) space as a pure form of intuition.
