 | | Plato's philosophy rejects scientific rationalism (establishing facts through experiment) in favour of arguments, because mind, not matter, is fundamental, and material objects are merely imperfect copies of abstract and eternal ‘ideas’. |
 | | Born of a noble family, Plato entered politics on the aristocratic side, and in philosophy became a follower of Socrates. |
 | | Moreover, the Earth, which lay at the exact centre of the cosmos, was a sphere and was surrounded by a band of crystalline spheres which held in place the Sun, the Moon, and the planets. |
