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.
Heraclitus and Parmenides both agreed that the world could be reduced to one thing, but they came into a fundamental disagreement about what that one thing was. Heraclitus thought that everything was made out of fire, because a fundamental property of the universe was that it was always changing and the only other thing that he could think about that was always changing was fire.
