But also of the large there is always a larger, and it is equal in amount to the small. According to some interpreters, what is remarkable about this fragment, and others similar to it, is that it indicates the extent to which Anaxagoras grasped the notion of infinity. It satisfied the Parmenidian demand that nothing can come into or out of being and it accounted for the plurality and change that constitutes our world of experience.
If, according to Anaxagoras, everything contains a portion of everything, then what makes something rice, for instance what it is? As such, a substance like rice, while containing everything, contains a higher proportion of white, hardness, etc. Simply stated, rice contains more stuff that makes it rice than wood or any other substance. Presumably, rice also contains higher proportions of flesh and hair than wood does. He does, however, provide us with a macro level explanation for the origins of the world as we experience it.
It is to his cosmogony that we now turn our attention. The traditional theories generally depict an original unity which begins to become separated off into a series of opposites. Prior to the beginning of world as we know it everything was combined together in such a unified manner that there were no qualities or individual substances that could be discerned. But before these things separated off, when [or, since] all things were together, not even any color was manifest, for the mixture of all things prevented it—the wet and the dry, the hot and the cold, the bright and the dark, there being also much earth in the mixture and seeds unlimited in amount, in no way like one another.

For none of the other things are alike either, the one to the other. Since this is so, it is necessary to suppose that all things were in the whole.
Anaxagoras (c. 500—428 B.C.E.)
Therefore, the origin of the world is depicted through this process of motion and separation from the unified mixture. In proposing an initiator or causal explanation for the origins of the process, however, Anaxagoras separates himself from his predecessors.

As is previously mentioned, it is rather significant that Anaxagoras postulates an explanation for the movement of the cosmos, something that prior cosmogonies did not provide. But how is this explanation to be understood? From the passage above, one may infer that Mind serves simply as the initial cause for the motion, and once the rotation is occurring, the momentum sets everything else into place.
In this instance it is tempting to assign a rather deistic function to Mind. In this case it is tempting to characterize Mind in theistic terms. Both of these temptations should be avoided, for Anaxagoras remained fully naturalistic in his philosophy. In fact, the uniqueness of Anaxagoras is that he proposed a rationalistic governing principle that remained free from the mythical or theological characteristics of prior cosmogonies. His philosophical successors, particularly Socrates, Plato and Aristotle, are very excited to find in Anaxagoras a unifying cosmic principle which does not allude to the whims of the gods.
They hope to find in him an extension of this principle into a purpose-driven explanation for the universe. Alas, they are all disappointed that Anaxagoras makes no attempt to develop his theory of Mind in such a way. What Socrates, Plato and Aristotle were hoping to discover in Anaxagoras was not simply an account of how the cosmos originated an efficient cause , but an explanation for why and for what purpose the cosmos was initiated a final cause.

Their initial excitement about his theory is replaced by disillusionment in the fact that Anaxagoras does not venture beyond mechanistic explanatory principles and offer an account for how Mind has ordered everything for the best. Despite the fact that Anaxagoras did not pursue matters as far as his teleologically-minded successors would have liked, his theory of Mind served as an impetus toward the development of cosmological systems that speculated on final causes. Thus far, we have examined the role of Mind in the development of the world. But what exactly is Mind, according to Anaxagoras?
Based on the evidence in the fragments, this is a rather difficult question to answer, for Mind appears to have contradictory properties. Elsewhere, Anaxagoras emphasizes the autonomy and separateness of Mind:.
The rest have a portion of everything, but Mind is unlimited and self-ruled and is mixed with no thing, but is alone and by itself. For if it were not by itself but were mixed with something else, it would have a share of all things, if it were mixed with anything. For in everything there is a portion of everything, as I have said before. And the things mixed together with it would hinder it so that it would rule no thing in the same way as it does being alone and by itself.
For it is the finest of all things and the purest, and it has all judgment about everything and the greatest power. Mind is material, but it is distinguished from the rest of matter in that it is finer, purer and it appears to act freely. It is the mind of a plant which enables it to seek nourishment and grow, but this dynamic agent in a plant is not distinct from the plant itself.
The Mind of the cosmos is a dynamic governing principle which is immanent to the entire natural system while still maintaining its transcendental determining power. A few other theories are worth mentioning, though it should be pointed out that many of them are probably not original and our primary knowledge of these views arises from second-hand sources. As a natural scientist and philosopher of his day, Anaxagoras would have been particularly concerned with the subjects of astronomy and meteorology and he made some significant contributions in these areas.
It was mentioned above that his outlook on the heavenly bodies played a part in his condemnation in Athens. His beliefs about the earth, moon and sun are clearly articulated in the following lengthy quote from Hippolytus, a source from the late second century CE:. The earth [according to Anaxagoras] is flat in shape.
It stays up because of its size, because there is no void, and because the air, which is very resistant, supports the earth, which rests on it. Now we turn to the liquids on the earth: The sea existed all along, but the water in it became the way it is because it suffered evaporation, and it is also added to from the rivers which flow into it.
Rivers originate from rains and also from subterranean water; for the earth is hollow and has water in its hollows. The Nile rises in the summer because water is carried down into it from the snow in the north. The sun, the moon, and all the heavenly bodies are red-hot stones which have been snatched up by the rotation of the aether. Below the heavenly bodies there exist certain bodies which revolve along with the sun and the moon and are invisible….
The moon is below the sun, closer to us.
The sun is larger than the Peloponnesus. The moon does not shine with its own light, but receives its light from the sun…. Eclipses of the moon occur when the earth cuts off the light, and sometimes when the bodies below the moon cut off the light. Eclipses of the sun take place at new moon, when the moon cuts off the light…. Anaxagoras was the first to describe the circumstances under which eclipses occur and the way light is reflected by the moon.
He said that the moon is made of earth and has plains and gullies on it.

Along with his contributions in Astronomy and Meteorology, Anaxagoras proposed a theory of sensation that works on the principle of difference. When a cold hand touches a hot object the agent will only experience the sensation of heat because her hand is cold and the hot object has brought about some sort of change. Therefore, in order for this change the sensation to occur, it is necessary that unlike things interact with each other, i.
Creation, Evolution, and Thomas Aquinas
If like things interact—hot with hot, for example—then no change occurs and there is no sensation. Perception works the same way as our sense of touch. Humans are able to see better during the daytime because our eyes are generally dark. Furthermore, perception works the same way as touch for Anaxagoras in that there is a physical interaction with the perceiver and the object perceived. Since a sensation requires an encounter with an opposite, Anaxagoras also maintained that every sensory act is accompanied by some sort of irritation.
Anaxagoras theory of sensation and perception is in direct opposition to Empedocles who maintained that perception could be accounted for by an action between like objects.
