Aristotle (384 BCE-322 BCE) lived in ancient Greece, and is known as one of the most highly regarded philosophers and scientists in human history. Though he was prolific in many fields, some of his most famous contributions include creating a discipline of formal logic, zoology, and his ethical and political theories. He studied under and with Plato in Athens, which is reflected in many of his writings. In his later years, Aristotle founded his own school called the Lyceum where he taught students and lectured to the larger public for free.
