Definition: Metaphysics is a philosophical discipline that explores questions about how things in reality are known, understood or experienced. It seeks to provide an objective explanation for phenomena using concepts from both the natural sciences and philosophy. The word "metaphysics" comes from Latin and means "understanding of things without being made." This concept emphasizes on understanding or knowledge through a methodical approach rather than relying solely on sensory experience. In its broadest sense, metaphysics deals with questions such as what is reality, how it can be known, and the nature of consciousness. It also explores issues related to scientific realism, ethical perspectives, and philosophical foundations of existence. Metaphysical inquiry often involves a close examination of philosophical arguments and interpretations, and a study of the relationship between metaphysical ideas and empirical evidence or intuition. In modern philosophy, metaphysics has been associated with the work of philosophers like David Hume, George Berkeley, and Bertrand Russell. The term "metaphysics" is used in various fields including psychology, neuroscience, and philosophy to discuss how things are known through a methodical approach rather than relying solely on sensory experience.
