Metaphysical concepts explore the fundamental nature of reality, existence, and the relationship between mind and matter. This branch of philosophy addresses questions about what is real, the nature of objects, and the existence of abstract entities like numbers or ideas. It seeks to understand the principles that govern the universe beyond physical observation. Key topics in metaphysics include ontology, which studies the nature of being, and cosmology, which examines the origins and structure of the universe. Metaphysical inquiry often overlaps with other disciplines, such as epistemology, the study of knowledge, and ethics, which explores moral values and principles.
