本書作者享利·E·阿利森觀為美國波士頓大學教授，當代英語世界研究康德哲學的權威學者。本書齣版於1990年。書中對康德的自由理論進行全麵、詳盡、細緻的探討。作者在第一編中指齣在《純粹理性批判》的核心之處存在著關於理性行為能力的內在一貫的一般理論，接著在第二編運用這種關於理性行為能力的論述，作為理解康德的道德行為能力概念以及與之相關的道德心理學的鑰匙，第三編則集中探討康德在《道德形而上學基礎》和《實踐理性批判》中為道德律和自由建立根據的努力。作者提齣“結閤論”和“交互論”，來解讀康德本人對自由概念與道德律的論證，這無疑是康德哲學研究界的一個重大獨創，將會影響一代學者對康德哲學的研究。

In his new book the eminent Kant scholar Henry Allison provides an innovative and comprehensive interpretation of Kant's concept of freedom. The author analyzes the concept and discusses the role it plays in Kant's moral philosophy and psychology. He also considers in full detail the critical literature on the subject from Kant's own time to the present day. In the first part Professor Allison argues that at the centre of the Critique of Pure Reason there is the foundation for a coherent general theory of rational agency. The second part employs this account of rational agency as a key to understanding Kant's concept of moral agency and associated moral psychology. The third part focuses on Kant's attempt to ground both moral law and freedom in the Groundwork and the Critique of Practical Reason. This is a major contribution to the interpretation of Kant which will be of special interest to scholars and graduate students of Kant's moral theory.
