Key themes and ideas explored in "The Critique of Practical Reason" include:The Autonomy of Practical Reason: Kant distinguishes between theoretical reason (concerned with knowledge and understanding) and practical reason (concerned with morality and action). He argues that practical reason is autonomous, meaning it does not depend on empirical observations or external influences but derives its moral principles from pure reason.The Moral Law and Categorical Imperative: Kant presents the moral law as the "categorical imperative," which is an unconditional and universal principle that governs moral actions. He formulates the categorical imperative in various ways, such as "Act only according to that maxim whereby you can at the same time will that it should become a universal law" and "Treat humanity, whether in your own person or in the person of any other, in every case at the same time as an end and never merely as a means to an end."The Concept of Duty: Kant argues that moral actions are guided by the concept of duty, and moral worth lies in performing actions out of a sense of duty, regardless of personal inclinations or consequences.
