He is considered the greatest classical Greek philosopher and one of the founders of Western philosophy. Socrates was the son of the Athenian Sophroniscus and Phainarete. When he grew up, like most young people of that time, he followed the profession of his father, who was a stonemason. Thus, Socrates turned to sculpture. In his philosophical research, Socrates analyzed questions of society, politics and even religion. Gradually, he gained fame and, consequently "followers", as his "lessons" were held in all parts of the city. His contribution to philosophy was so great that he became a "landmark of the ages", since all philosophers before him were called "pre-Socratics"”

Socrates, who lived up to his name, went down in history not only for his words, but left a strong legacy for the future of philosophy. This was a generation of disciples who spread, developed, and even challenged his words. The Athenians, Plato and Antisthenes, Euclid, Megareus, Phaedon of Ilia, and many others were the next "generation" of philosophers who further developed philosophy and founded philosophical schools in many parts of Greece. But there came a time when his city, Athens, felt that the great philosopher was corrupting the youth with his analyses and leading them to question the gods and the institutions. Thus, he was put on trial. In this trial, the Athenians sentenced Socrates to death and forced him to drink hemlock. But strange as it may seem to us, given the greatness of this man, this trial was perfectly legal and perhaps not so unjust. Despite the urging of his students to flee, Socrates eventually accepts the charge, dies, and remains in history.
