Aristotle (384 BC to March 7, 322 BC) was born in Starkila, Thrace, Greece. He was an ancient Greek philosopher and scientist, a student of Plato and a teacher of Alexander the Great. Together with Plato and Socrates, he is called the founder of western philosophy.
Aristotle was first and foremost a great philosopher. Although he was a student of Plato, he gave up the idealistic view held by his teacher. Plato believes that idea is the prototype of physical object, which exists independently of physical object. Aristotle believes that the real world is made up of all kinds of things, and their forms and materials are harmonious.
"thing" is the substance of things, and "shape" is the individual characteristic of all things. Just like a chicken flying around with wings, the "shape" of this chicken is that it can flap its wings, coo and lay eggs.
The origin of geocentric theory:
The origin of geocentric theory is very early Originally formed by Miletus School, it was later put forward by the ancient Greek scholar Odoksos. After being perfected by Aristotle, Ptolemy further developed into geocentric theory. In the 1300 years before the establishment of Heliocentrism in the 6th century, geocentric theory was always dominant.
Aristotle's geocentric theory holds that the universe is a limited sphere, which is divided into two layers: heaven and earth. The earth is located in the center of the universe, so the sun and the moon revolve around the earth and objects always fall to the ground. There are nine celestial bodies with equal distance outside the earth, and the order from inside to outside is: Moon Day, Mercury Day, Venus Day, Sun Day, Mars Day, Jupiter Day, Saturn Day, sidereal day Day and Power Day.
There is nothing in this outer space. God promoted the celestial bodies of stars, which led to the movement of all celestial bodies. The earth where human beings live stands quietly in the center of the universe. Greek philosophers believe that eternal and sacred celestial bodies can only make uniform circular motion corresponding to their noble status.
