ANA- XAGORAS, THE GREEK PHILOSOPHER.

Ana-Xagoras [500-428 BC](Greek: Lord of the Assembly) was an important Pre-Socratic natural philosopher and scientist.
He was born in Ion-Ia in the town of Clazomenae, a lively port city on the coast of present-day Turkey.
He was one of the first philosophers to move to Athens as a base, which was then rapidly becoming the centre of Greek culture. He lived and taught there for 30 years.
Ana-Xagoras is often credited with making Athens the home of Western philosophical and physical speculation. The consistent image of Ana-Xagoras presented throughout Antiquity is that of a person entirely consumed by the pursuit of knowledge. In fact, he maintained that the opportunity to study the universe was the fundamental reason why it is better to be born than to not exist.
His philosophical beliefs and teachings were quite contrary to the standard orthodoxy of the time, particularly his view that the heavenly bodies were fiery masses of rock whirling around the earth.
He was best known for his cosmological theory of the origins and structure of the universe. He maintained that the original state of the cosmos was a thorough mixture of all its ingredients, although this mixture was not entirely uniform, and some ingredients were present in higher concentrations than others and varied from place to place. With that in mind he also speculated that in the physical world everything contains a portion of everything else. His observation of how nutrition works in animals led him to conclude that the food chain works in a way that an animal eats to turn into bone, hair, flesh, an so forth, then, it must already contain all of those constitutes within it.
His second significant theory or postulate was that at some point in time, this primordial mixture was set in motion by the action of a supreme mind, and the whirling motion that shifted and separated out the ingredients, ultimately producing the cosmos of separate material objects with differential properties that we perceive today, was the result of it.
Ana-Xagoras did not elucidate on the precise nature on the supernatural Mind, but distinguished it as finer, purer and able to act freely, and present in some way in everything. A kind of dualism.
Dualism was understood as two kinds of reality: material (physical) and immaterial (spiritual). Mind and Body was seen in some categorical way separated from each other, and that, mental phenomena were non-physical in nature.
In the physical sciences, Ana-Xagoras gained notoriety because he was the first to give the correct explanation of eclipses, and was also both famous and notorious for his scientific theories, including his claims that the sun is a mass of red-hot metal, that the moon is earthy, and that the stars are fiery stones.
