Aristotle - Philosophy and Ethics

Science

Physics

Aristotle extended the ancient Greek belief of four earthly elements with a new one, called Aether. The common four elements were Fire, Earth, Air and Water. He thought of Aether as the divine substance that makes up the heavenly spheres and bodies (the stars and planets). Aristotle's physics also contained motion, causality, optics, chance and spontaneity.

In one of his works on optics, the first evidence of a camera obscura can be found.
