The Critique of Practical Reason

"The Critique of Practical Reason," written by Immanuel Kant, explores moral philosophy, focusing on how we make ethical decisions. Kant argues that reason should guide our actions, emphasizing that moral principles are universal and based on a duty to act according to what is right, rather than on personal desires or consequences. He introduces the concept of the "categorical imperative," a rule for determining moral actions by considering whether the action could be made a universal law. Ultimately, Kant seeks to establish a rational foundation for ethics, highlighting the importance of autonomy and moral responsibility in human behavior.
