Abstract
This paper considers the aporia in Dialectic of Enlightenment in two aspects of the self-destruction and self-critique of enlightenment and then emphasizes the dual vision which Horkheimer and Adorno hold on rationality. Firstly, it traces the explanation of the self-destruction of enlightenment so as to make explicit that it results in another form of the aporia, the self-critique of enlightenment. This is followed by formulating the criticism into two aspects, that Horkheimer and Adorno’s aporia leads them to be confronted by a self-contradiction. I argue that the criticism neglects their narrative strategy of history as critique and the methodology of immanent critique of Horkheimer and Adorno. In conclusion, it is elucidated that Horkheimer and Adorno rightly posit their aporia and suggest a proper solution, by which we could take the dual vision on rationality and their own model of immanent critique as its significances.
