What does metaphysics primarily study?

Metaphysics primarily explores the fundamental nature of reality and existence, delving into questions about what is ultimately real, the nature of being, and the structure of the world. This field of study addresses concepts such as existence, objects and their properties, space and time, cause and effect, and possibility. It seeks to go beyond the physical sciences by examining the underlying principles that govern all aspects of life and the universe.

The other options focus on different areas of philosophy. For example, the study of the principles of art and beauty pertains to aesthetics, which examines how we perceive and value art and beauty in various forms. The nature of knowledge is the domain of epistemology, which investigates the sources, scope, and limits of knowledge and belief. Human conduct and character fall under ethics, which evaluates moral principles and how they guide behavior. Therefore, the distinctive focus of metaphysics on reality and existence sets it apart from these other philosophical branches.
