Originally published in 1788, the Critique of Practical Reason ( Kritik der praktischen Vernunft ) is the second of Immanuel Kant's three critiques, following the Critique of Pure Reason . Critique of Practical Reason is focused more on Kant's moral philosophy and decisive influence over the development of the fields ethics and oral philosophy, serving as the primary reference point for future works of deontological moral philosophy. This edition is based on a translation previously published in 1889 by scholar Thomas Kingsmill Abbott (1829-1913) Immanuel Kant (1724-1804) is widely considered to be one of the greatest thinkers of all time and one of the most important figures in Western philosophy. He is best known for his seminal work, the Critique of Pure Reason , which is credited with revolutionizing philosophical thought and laying the foundations for modern philosophy. Kant's philosophy was deeply rooted in the Enlightenment tradition and focused on the concept of universal morality and the power of reason. He believed that all humans have a moral obligation to obey certain laws, and that these laws should be based on rational principles. Kant also argued that all knowledge comes from experience, and that the ultimate truth lies in a synthesis of intuition and reason. Further, he argued that morality must be based on universal principles, rather than on subjective considerations. Kant's work has had a profound impact on the development of many philosophical schools of thought, including Kantianism, Neo-Kantianism, and Post-Kantianism. His influence continues to be felt in many fields, from philosophy to theology and beyond.
