Aristotle was a Greek philosopher who lived between 384-322 B.C. He was one of the greatest thinkers of the world and his written works encompassed all major areas of thought. Aristotle mistakenly believed that the Earth was at the center of the universe and made up of only four elements: earth, water, air, and fire.
While Aristotle's view that substance is form clearly draws from Platonic doctrine, his insistence that form can exist only in conjunction with matter marks a radical departure from Plato's teachings. According to Aristotle, substance is form, which in general can only exist when combined with matter.n Aristotle's theory, whatever exists is a combination of both form and matter. Matter cannot exist without form nor can form exist without matter. Since a vacuum is defined as a place devoid of matter, a vacuum thus cannot exist.
