Philosophy is the study of fundamental questions about existence, knowledge, values, and reason. It encourages us to think critically about our beliefs and the world around us. Philosophers like Socrates and Plato explored ideas about truth, justice, and the nature of reality, helping us understand our place in the universe. Through various branches such as ethics, metaphysics, and epistemology, philosophy examines how we should live, what is real, and how we know what we know. It invites us to engage in deep thinking and discussion, fostering a greater understanding of ourselves and our relationships with others.
