Book excerpt: Kojin Karatani's Transcritique introduces a startlingly new dimension to Immanuel Kant's transcendental critique by using Kant to read Karl Marx and Marx to read Kant. In a direct challenge to standard academic approaches to both thinkers, Karatani's transcritical readings discover the ethical roots of socialism in Kant's Critique of Pure Reason and a Kantian critique of money in Marx's Capital. Karatani reads Kant as a philosopher who sought to wrest metaphysics from the discredited realm of theoretical dogma in order to restore it to its proper place in the sphere of ethics and praxis. With this as his own critical model, he then presents a reading of Marx that attempts to liberate Marxism from longstanding Marxist and socialist presuppositions in order to locate a solid theoretical basis for a positive activism capable of gradually superseding the trinity of Capital-Nation-State.
