Critique of Practical Reason (Kritika Prakticheskogo Razuma)

Immanuel Kant is the greatest philosopher of the modern era, the founder of classical German philosophy. Kant's range of professional interests was unusually broad. He developed a theory of the origin of the solar system, studied earthquakes, and lectured on physics and geography. However, Kant's most important works, which truly revolutionized his thinking, are the so-called 'critical works.' 'The Critique of Practical Reason' was published in 1788. This is Kant's main moral and philosophical work. Starting from the concept of a universal moral law (the categorical imperative), Kant offers a strictly ethical justification for it. At the heart of this law lies the idea of ​​transcendental freedom, or personal freedom of will, which is inherent in man and is unthinkable without moral self-discipline. For, as the philosopher believed, only an absolutely voluntary act can be recognized as moral.
