Publications on Cohen in the English language are small in number and this volume aims to fill the gap. It offers an analysis of Cohenโs System of Philosophy - the three-volume classic on logic, ethics, and aesthetics - and his writings on Judaism and religion. The book highlights Cohenโs contributions in these fields, including his discussions with Maimonides, Leibniz, Kant, and Hegel. It demonstrates the congeniality of Cohenโs critical idealism as expounded in the System and his writings on Judaism, and offers an overview of contemporary Cohen research.
