Philosophy is the study of fundamental questions about existence, knowledge, values, reason, mind, and language. It involves reasoning and arguing to understand complex issues rather than just observing data. Philosophers examine concepts like truth, justice, and beauty through thought experiments, analyzing particular cases, and debating different viewpoints. The goal is to develop rational, systematic frameworks for understanding broad topics rather than proving absolute truths. Major areas of philosophy include logic, epistemology, metaphysics, ethics, aesthetics, and political philosophy.
