Philosophy is the pursuit of wisdom, truth, and knowledge through deep, fundamental thinking about the nature of the universe, human existence, values, and meaning. It involves asking broad and fundamental questions that often cannot be answered through empirical means alone, such as what justice is, what knowledge is, or what constitutes right conduct. Philosophy uses reasoned arguments and reflection to explore these topics and deepen understanding, aiming to improve how we think and act in life. Philosophy covers a wide range of subjects including ethics (moral principles), epistemology (nature and limits of knowledge), metaphysics (nature of reality), logic (correct reasoning), aesthetics (beauty and art), and more. It calls for responsiveness, reflection, reason, and reevaluation in thinking. Philosophical questions include inquiries like what is fairness, freedom, responsibility, or the meaning of life. Philosophy is different from science because it often deals with questions not fully answerable by experiments, and it critically evaluates concepts and beliefs based on logic and careful thought. It is a systematic, rational inquiry into basic questions that shape our worldview and values.
