Aristotle (Ancient Stageira, 384 BC - Ancient Chalkida, 322 BC) was an ancient Greek philosopher and scientist born in Stageira, Halkidiki, Macedonia. At the age of 17 he entered the Academy of Plato in Athens, where he remained until the age of 37. After Plato's death, he left Athens and, by order of Philip, undertook the teaching of Alexander the Great in 343 BC / 42. According to the Εncyclopaedia Britannica: "Aristotle was the first genuine scientist in history ... and every subsequent scientist owes him something"

As a teacher of Alexander the Great, Aristotle acquired various opportunities and plenty of supplies. Thus, he founded a library in the Lyceum, which helped in the production of hundreds of his works. The fact that he was a student of Plato led him to the views of Platonism, but later, after Plato's death, he was led, more, to empirical studies and shifted from Platonism to empiricism. He believed that the ideas and knowledge of all peoples were ultimately based on perception. Many of his works were based on his views on the natural sciences.

Together with Plato's teacher he was an important figure in the philosophical thought of the ancient world, and his teaching penetrated deeply into Western philosophical and scientific thought until the Scientific Revolution of the 17th century. He was a naturalist, philosopher, creator of logic and the most important of the dialectics of antiquity.

His total influence often ranks him among the leading world figures of all time with the greatest influence, along with his teacher, Plato, and his student, Alexander the Great.
