Fire (classical element)
Fire is one of the four fundamental elements in ancient Greek philosophy, alongside earth, water, and air. It was associated with heat and dryness.
Empedocles: A fifth-century BCE Greek philosopher who proposed four eternal roots: earth, water, air, and fire. His four-root theory established fire as one of nature’s basic constituents.
Classical element: A basic substance or principle used in ancient systems to explain the composition of the world. Fire is one member of this broader explanatory framework.
Aristotelian physics: A system of natural philosophy explaining matter, motion, and the cosmos through Aristotle’s principles. Its account of fire combines elemental composition, qualities, and natural place.
Humorism: An ancient medical theory that explained health through the balance of four bodily fluids. Its four-humor scheme linked bodily temperaments and fluids to elemental qualities.
Aristotle: An ancient Greek philosopher whose natural philosophy organized matter through four elements and their qualities. He explained fire through heat and dryness and placed it in a cosmic order.
Four elements: The ancient Greek scheme of earth, water, air, and fire as fundamental constituents of the world. Fire’s role becomes clear in relation to the other three elements.
Natural place: The characteristic cosmic location toward which an element moves in Aristotelian physics. Fire’s natural motion is upward, toward the region above air.
Four humors: Blood, phlegm, yellow bile, and black bile, the fluids central to ancient humorism. Yellow bile was associated with fire in later correspondences between body and elements.
Heraclitus: A Greek philosopher known for describing change as fundamental and using fire as a central image. His cosmic fire connects the element with continual transformation.
Qualities (Aristotelian physics): The hot, cold, wet, and dry qualities used in Aristotelian physics to distinguish the elements. Heat and dryness jointly characterize fire in this system.
