Final answer:
The ancient Greek philosophers used reason and logic to understand the world, engaging in philosophical discussions and debates. They relied on critical thinking and rational analysis rather than experimentation and observation.
Step-by-step explanation:
The ancient Greek philosophers, such as Socrates, Plato, and Aristotle, used reason and logic to understand the world around them. They engaged in philosophical discussions and debates to explore various aspects of the natural world, ethics, politics, and human nature. They relied on critical thinking and rational analysis rather than experimentation and observation, which sets them apart from later scientific approaches. For example, Greek philosophers sought to explain natural phenomena like wind and lightning as natural forces rather than the actions of gods or spirits.
