Immanuel Kant is the greatest philosopher of Western Europe, one of the leading thinkers of the Enlightenment, the founder of German classical philosophy, the founder of critical idealism, who made a decisive contribution to the development of the European philosophical tradition. Only a rational being has a will, thanks to which it is able to perform actions based on principles .And only a rational being, when achieving what he wants, is able to be guided by the law of morality. This and much more is discussed in the work “Fundamentals of the Metaphysics of Morals,” which became a prelude to the “Critique of Practical Reason.” The collection also includes “Anthropology from a Pragmatic Point of View” - the last major Kant's work, written on the basis of lecture notes, which presents a systematization of contemporary knowledge about man for the philosopher.
