Classical Elements

Classical Elements,Part I


4-Astrology and the classical elements


The dominant theory of classical elements, held by the Hindu, Japanese, and Greek systems of thought, is that there are five elements, namely Earth, Water, Air, Fire, and a fifth element known variously as Idea, Void "quintessence" or Aether (the term "quintessence" derives from "quint" meaning "fifth"). In Greek thought the philosopher Aristotle added aether 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 stars cannot be made out of any of the four elements but must be made of a different, unchangeable, heavenly substance. The Greek Pythagoreans used the initial letters of these five elements to name the outer angles of their pentagram.
The Greek names of the elements are as follows:

Γαια, gaia earth
ύδωρ, hydor,
water
άήρ, aer,
air
έιλή, heile,
heat (fire)
ίδέα,
idea or ίερόν, hieron "a divine thing"

These five elements are sometimes associated with the five platonic solids.
The Japanese and Hindu systems use these same five classical elements but use a different name for the fifth element: void in the Japanese system and aether or akasha in the Hindu system. "Idea" is the preferred modern term, and lends itself well to the idea that algorithms, software, or other similar "cyberspace" processes be categorized as belonging to the fifth element. In other words, just as the mind belongs to Idea, even though the brain is a mixture of solid ("Earth") and liquid ("Water"), software also belongs to Idea even though the hardware it runs on, i.e. silicon chips, etc., is made from solid ("Earth") matter.
The fifth Classical Element (Idea) may be further sub-divided into living and non-living. For example, the mind is an example of a living form of Idea whereas computer software is an example of non-living Idea.

1-1- Classical elements in Greece

The Greek classical elements are fire , earth , air , and water . They represent in Greek philosophy, science, and medicine the realms of the cosmos wherein all things exist and whereof all things consist. The ancient Greek word for element (stoicheion) literally meant "letter (of the alphabet)", the basic unit from which a word is formed.
Plato mentions the elements as of pre-Socratic origin, a list created by the Ionian philosopher Empedocles (ca. 450 BC). Empedocles called these the four "roots"; Plato seems to have been the first to use the term "element (stoicheion)" in reference to air, fire, earth, and water.



Air is primarily wet and secondarily hot.
Fire is primarily hot and secondarily dry.
Earth is primarily dry and secondarily cold.
Water is primarily cold and secondarily wet.

One classic diagram (right) has one square
inscribed in the other, with the corners of one being the classical elements, and the corners of the other being the properties. The opposite corner is the opposite of the these properties, "hot - cold" and "dry - wet"
According to
Galen, these elements were used by Hippocrates in describing the human body with an association with the four humours: yellow bile (fire), black bile (earth), blood (air), and phlegm (water).
The concept of the classical elements proved extremely persistent in Europe, lasting through the Middle Ages to the early modern era. Just as the
Aristotelian dogma was related to the Greek world view, the idea of classical elements in the Middle Ages composed a large part of the medieval world view. The Roman Catholic Church supported the Aristotelian concept of aether because it supported the Christian view of earthly life as impermanent and heaven as eternal.
In Western
astrology the concept of the four classical elements has survived from antiquity up until the present. The twelve signs of the zodiac are divided into the four elements: Fire signs are Aries, Leo and Sagittarius, Earth signs are Taurus, Virgo and Capricorn, Air signs are Gemini, Libra and Aquarius, and Water signs are Cancer, Scorpio, and Pisces. Most modern astrologers still view the four classical elements as a critical part of interpreting the astrological chart.
In
divinatory tarot,the suits of cups, swords, wands (batons) and pentacles (coins) are said to correspond to water, air, fire, and earth respectively. These correspond in the modern deck of playing cards to hearts, spades, clubs, and diamonds.
