Aristotelian philosophy is based on the ideas of the ancient Greek philosopher Aristotle, who lived from 384 to 322 BCE. It emphasizes the importance of empirical observation and logic in understanding the world. Aristotle believed that knowledge comes from experience and that we can learn about reality through our senses. He also introduced concepts such as the four causes, which explain why things exist and change. Another key aspect of Aristotelian philosophy is the idea of virtue ethics, which focuses on the character of individuals rather than specific actions. Aristotle argued that living a good life involves developing virtues, such as courage and wisdom, to achieve eudaimonia, or human flourishing. This approach has influenced many areas, including ethics, politics, and science.
