Editing Classical element (section)

==== Aether ====
[[Aristotle]] added a fifth element, [[Aether (classical element)#Fifth element|aether]] ({{lang|grc|αἰθήρ}} {{transliteration|grc|aither}}), as the quintessence, reasoning that whereas fire, earth, air, and water were earthly and corruptible, since no changes had been perceived in the heavenly regions, the [[star]]s cannot be made out of any of the four elements but must be made of a different, unchangeable, heavenly substance.{{sfnp|Lloyd|1968|pp=[https://archive.org/details/aristotlegrowths0000lloy/page/133 133–139]}} It had previously been believed by pre-Socratics such as Empedocles and [[Anaxagoras]] that aether, the name applied to the material of heavenly bodies, was a form of fire. Aristotle himself did not use the term ''aether'' for the fifth element, and strongly criticised the pre-Socratics for associating the term with fire. He preferred a number of other terms indicating eternal movement, thus emphasising the evidence for his discovery of a new element.<ref>{{Cite encyclopedia |year=1971 |chapter=Aristotle's analysis of change and Plato's theory of Transcendent Ideas |publisher=SUNY Press |last=Chung-Hwan |first=Chen |author-link=Chen Chung-hwan |editor-last=Anton |editor-first=John P. |volume=2 |pages=406–407 |isbn=0873956230 |editor2-first=Anthony |editor2-last=Preus |title=Ancient Greek Philosophy}}.</ref> These five elements have been associated since Plato's [[Timaeus (dialogue)|''Timaeus'']] with the five [[platonic solid]]s. Earth was associated with the cube, air with the octahedron, water with the icosahedron, and fire with the tetrahedron. Of the fifth Platonic solid, the dodecahedron, Plato obscurely remarked, "...the god used [it] for arranging the constellations on the whole heaven". [[Aristotle]] added a fifth element, [[aether (classical element)|aither]] (aether in Latin, "ether" in English) and postulated that the heavens were made of this element, but he had no interest in matching it with Plato's fifth solid.<ref>Wildberg (1988): Wildberg discusses the correspondence of the Platonic solids with elements in ''Timaeus'' but notes that this correspondence appears to have been forgotten in ''[[Epinomis]]'', which he calls "a long step towards Aristotle's theory", and he points out that Aristotle's ether is above the other four elements rather than on an equal footing with them, making the correspondence less apposite.</ref>
