Metaphysics is the branch of philosophy that examines the fundamental structure of reality. It is traditionally seen as the study of mind-independent features of reality but some modern theorists understand it as an inquiry into the conceptual schemes that underlie human thought and experience.
Many general and abstract topics belong to the purview of metaphysics. It investigates what existence is, which features all entities have in common, and how they are divided into categories of being. An influential contrast is between particulars, which are individual unique entities, like a specific apple, and universals, which are general repeatable entities that characterize particulars, like the color red. Modal metaphysics examines what it means for something to be possible or necessary. The nature of space and time is another broad topic, with metaphysicians discussing how to conceive them and how to conceptualize change. A closely related issue concerns the essence of causality and its relation to the laws of nature. Other topics include how mind and matter are related, whether everything in the world is predetermined, and whether there is free will.
Metaphysicians employ various methods to conduct their inquiry. Traditionally, they rely on rational intuitions and abstract reasoning but have more recently also included empirical approaches associated with scientific theories. Due to the abstract nature of its topic, metaphysics has received criticisms questioning the reliability of its methods and the meaningfulness of its theories. Metaphysics is relevant to many fields of inquiry that often implicitly rely on metaphysical concepts and assumptions.
The origin of metaphysics lies in the ancient period with speculations about the nature of reality and the universe, like the ones found in the Upanishads in ancient India, Daoism in ancient China, and pre-Socratic philosophy in ancient Greece. Aristotle conceived the scope of metaphysics under the title first philosophy and was influential in shaping the discussion of the nature of universals in the subsequent medieval period. The modern period saw the emergence of many rationalist and idealist systems of metaphysics. In the 20th century, various criticisms of earlier theories were voiced and new approaches to metaphysical inquiry were proposed.
