Aristotle (March 384 -322 BC) was born in Stajila, Thrace. His father was a court doctor of the Macedonian king. /kloc-at the age of 0/7, he went to Athens Academy and studied under Plato for 20 years until Plato died in 347 BC. He is full of reverence for his teacher, and wrote in his mourning poem: For such a stranger, the bad guys have no right to praise him, and their mouths can't say his name. It was the first time that he proved by words and actions that a virtuous person is a happy person, and none of us can compare with him. The admiration for Plato's personality did not make him blindly worship Plato's theory. According to legend, his motto is: "I love my teacher, and I love the truth more." He clearly criticized Plato's idealism, tried to overcome Plato's tendency to despise sensory experience and not pay attention to the study of motion changes, and founded his own philosophical system. After Plato's death, he left Athens, went to Yasos and opened a branch of the college.
