Derrida states that deconstruction is not a critique in the Kantian sense. This is because Kant defines the term critique as the opposite of dogmatism. For Derrida, it is not possible to escape the dogmatic baggage of the language we use in order to perform a pure critique in the Kantian sense. Language is dogmatic because it is inescapably metaphysical. Derrida argues that language is inescapably metaphysical because it is made up of signifiers that only refer to that which transcends them—the signified. In addition, Derrida asks rhetorically "Is not the idea of knowledge and of the acquisition of knowledge in itself metaphysical?" By this, Derrida means that all claims to know something necessarily involve an assertion of the metaphysical type that something "is" the case somewhere. For Derrida the concept of neutrality is suspect and dogmatism is therefore involved in everything to a certain degree. Deconstruction can challenge a particular dogmatism and hence de-sediment dogmatism in general, but it cannot escape all dogmatism all at once.
