Plato's student Aristotle (384– 322 BCE) did not maintain his former teacher's geometric view of the elements, but rather preferred a somewhat more naturalistic explanation for the elements based on their traditional qualities. This also makes fire the element with the smallest number of sides, and Plato regarded it as appropriate for the heat of fire, which he felt is sharp and stabbing, (like one of the points of a tetrahedron). In the Timaeus, Plato's major cosmological dialogue, the Platonic solid he associated with fire was the tetrahedron which is formed from four triangles and contains the least volume with the greatest surface area. 435 BCE), is best known for having selected all elements as his archai and by the time of Plato (427– 347 BCE), the four Empedoclian elements were well established. He was known as the 'weeping philosopher' and died of hydropsy, a swelling due to abnormal accumulation of fluid beneath the skin. He believed the goal of the soul is to be rid of water and become pure fire: the dry soul is the best and it is worldly pleasures that make the soul 'moist'. Heraclitus regarded the soul as being a mixture of fire and water, with fire being the more noble part and water the ignoble aspect. But it always was and will be: an ever-living fire, with measures of it kindling, and measures going out. This world, which is the same for all, no one of gods or men has made.

He believed fire gave rise to the other three elements: 'All things are an interchange for fire, and fire for all things, just like goods for gold and gold for goods.'

In one Greek myth, Prometheus stole fire from the gods to protect the otherwise helpless humans, but was punished for this charity. It was commonly associated with the qualities of energy, assertiveness, and passion. Fire is considered to be both hot and dry and, according to Plato, is associated with the tetrahedron.įire is one of the four classical elements in ancient Greek philosophy and science.
