Every era gives birth to its own heroes. Starting from the glory times of ancient Greece and the Roman Empire with Aristotle, Heracles and Alexander the Great, passing through the dark ages, when St. Thomas and Roger Bacon created eternity and concluding with the creators of modern times – Eddisson and Enshtein, humanity created idealistic images of its best representatives. Formally, Kant was the ideological opponent of Newton, the rational genius, who made knowledge and mind exist at the level of God. Kant, the creator of the first scientific model of the creation of stars and planets, came to the position of the limits of practical morality. «The Critique of Practical Reason» is Kant's second work after the «Critique of Pure Reason». In it he describes "practical activity" as opposed to prudent practice. Philosophers of modern times supposed that the human mind is the most powerful thing and that its capabilities are unlimited, from the laws of the mind derive the other laws and principles.

As the newspaper Vesti.ru writes, police officers arrested a young man suspected of shooting an opponent during a dispute over the work of the philosopher Immanuel Kant. Two young people argued about the philosopher's work, the dispute raised the emergency of the quarrel, and then one of them took the traumatic gun and shot his opponent in the head. Although it is worth emphasizing that men with their practical actions were contrary to Kant's moral ideas, this is the fate of many brilliant ideas, regardless of when they were realized, and because of this humanity will grow for a long time..
