PBS describes metaphysics as: "...a type of philosophy or study that uses broad concepts to help define reality and our understanding of it. Metaphysical studies generally seek to explain inherent or universal elements of reality which are not easily discovered or experienced in our everyday life. As such, it is concerned with explaining the features of reality that exist beyond the physical world and our immediate senses. Metaphysics, therefore, uses logic based on the meaning of human terms, rather than on a logic tied to human sense perception of the objective world.

Metaphysics might include the study of the nature of the human mind, the definition and meaning of existence, or the nature of space, time, and/or causality."
