From Critical to Prophetic Idealism: Ethics, Law, and Religion in the Philosophy of Hermann Cohen.

摘要

In this study of the nineteenth-century German-Jewish philosopher Hermann Cohen, I argue that Cohen's revision of Kantian ethics and moral theology is permeated with concepts drawn from and logically contoured by his interpretation of Maimonidean rationalism and Jewish sources, more generally. Through an idealizing hermeneutic, Cohen normativizes certain philosophical problems in post-Kantian philosophy and addresses them under the title of "pantheism" and "positivism". Between both pantheism and positivism, Cohen's idealism presents a middle path, which I describe as "prophetic idealism", or a philosophy of time and ideality that interprets history, law, and ethical normativity as future-oriented. In other words, "prophecy" intimates a methodological role for temporality in practical philosophy and introduces a new meaning for legality in ethics. Cohen therefore offers a philosophy of Judaism, as a philosophy of religion, by normativizing the idea of prophecy and making it a conceptual model for reason-giving, agency, legal norms and ethical action. By focusing upon the critique of both pantheism and positivism, this dissertation therefore argues that Cohen's negotiations of nineteenth-century philosophical problems introduces a normative role for Judaism as a public philosophy and the argument concludes by suggesting that Cohen's philosophy of Judaism is instructive for contemporary public philosophy.
