Philosophy studies fundamental questions about the nature of reality, knowledge, being, ethics, and human understanding. Its purpose is to examine and understand concepts such as truth, reason, morality, and the meaning of life. Philosophers use logical reasoning and critical thinking to consider these questions and develop different theories and perspectives. Philosophy covers a wide range of subjects including metaphysics (the nature of reality), epistemology (the study of knowledge), ethics (moral principles), logic (just thinking), and aesthetics (the nature of beauty and art). It invites deep thought and reflection on fundamental aspects of human existence and the world we live in.
