Final answer:
The metaphysical stage of anthropology studies the nature of reality and existence. It includes ontology, metaphysical questions, cosmology, and axiology.
Step-by-step explanation:
Metaphysics is a branch of philosophy that explores the nature of reality and existence. In anthropology, metaphysics is often studied through ontological anthropology, which examines how culture constructs our social and natural realities, and how we perceive and interact with them. Some main parts of the metaphysical stage of anthropology include ontology, which asks what exists and what is real; metaphysical questions about the existence of gods, souls, and other concepts; cosmology, which studies the origin of reality; and axiology, which explores the existence and order of values.
