Aristotle (384 BC - 322 BC)

Aristotle is often described as the father of logic. This may be a bit of an overstatement, as many math historians believe that some of the ideas attributed to Aristotle were not original to him. At the very least, Aristotle offered one of the first formal approaches to systemizing logical thought, called propositional logic. He established logical rules of thought that were referred to as syllogisms. For example, if all men are living creatures, and living creatures require water for their existence, then all men require water for their existence. Aristotle served as the personal tutor to King Philip II's son Alexander. Following the completion of Alexander's education, Aristotle founded his own school, the Lyceum. Some math historians suspect that many of the ideas attributed to Aristotle were actually first proposed by students at the Lyceum. Most famous for his discourses on logical thought, Aristotle also wrote on a wide range of philosophical topics, including works on politics, ethics, and physics. Even when Aristotle wrote on these disparate topics, he frequently integrated mathematical concepts into his writing. In his discussions regarding the well-known Zeno's paradoxes, he offered arguments that in some way foreshadowed many of the basic theory of limits in calculus, some two thousand years before that topic was formulated.
