Metaphysics

Metaphysics is a branch of philosophy that deals with the fundamental nature of reality and the universe, including questions about the nature of existence, the relationship between mind and matter, the nature of time and space, the existence of free will, and the existence of God or other supernatural entities. It is concerned with questions that cannot be answered by empirical observation or scientific investigation alone, but require philosophical analysis and contemplation. Metaphysics is often contrasted with epistemology, which deals with questions about knowledge and belief, and ethics, which deals with questions about morality and values.
