The transcendental problem that obsessed the great Western philosophers such as Kant and Husserl should be, according to Wittgenstein, conceived as a matter of understanding a process of reasoning in which a conclusion follows necessarily from stated rules. Once these rules, regarded as a priori categories by Kant and as eidos and eidetic relations by Husserl, are demonstrated to be no more than the language usages or rules of language-games related to our forms of life, Kant’s transcendental idealism and Husserl’s transcendental phenomenology no longer have a leg to stand on.
