Aristotle

Born in 384 BCE in Stagira, Aristotle was a student of Plato and went on to become the tutor of Alexander the Great. His wide-ranging work encompasses ethics, politics, metaphysics, logic, biology, and more. Aristotle's philosophy emphasized the pursuit of virtue, the importance of empirical observation, and the application of reason in understanding the natural world. His works, including "Nicomachean Ethics" and "Politics," continue to influence philosophy, science, and political thought.

Some insightful quotes attributed to Aristotle are:

1. "It is the mark of an educated mind to be able to entertain a thought without accepting it."
   

2. "We are what we repeatedly do. Excellence, then, is not an act but a habit."
   

3. "It is the nature of desire not to be satisfied, and most men live only for the gratification of it."
