Aristotle (384-322 BCE) was an ancient Greek philosopher and polymath who made substantial contributions to diverse fields such as biology, ethics, politics, metaphysics, logic, and aesthetics. A student of Plato, he established his own school, the Lyceum, in Athens and is celebrated for his empirical approach to knowledge, which emphasized observation and experience. Known to be intellectually curious, analytical, and methodical, Aristotle's systematic and organized thinking laid the groundwork for the scientific method.
