What is the most important aspect of Anaxagoras's system?
The most original aspect of Anaxagoras’s system was his doctrine of nous (“mind” or “reason”). The cosmos was formed by mind in two stages: first, by a revolving and mixing process that still continues; and, second, by the development of living things. In the first, all of “the dark” came together to form the night, “the fluid” came together to form the oceans, and so on with other elements. The same process of attraction of “like to like” occurred in the second stage, when flesh and other elements were brought together by mind in large amounts. This stage took place by means of animal and plant seeds inherent in the original mixture. The growth of living things, according to Anaxagoras, depends on the power of mind within the organisms that enables them to extract nourishment from surrounding substances. For this concept of mind, Anaxagoras was commended by Aristotle. Both Plato and Aristotle, however, objected that his notion of mind did not include a view that mind acts ethically—i.e., acts for the “best interests” of the universe.

What did Anaxagoras say about the impossibility of change?
Responding to the claims of Parmenides on the impossibility of change, Anaxagoras described the world as a mixture of primary imperishable ingredients, where material variation was never caused by an absolute presence of a particular ingredient, but rather by its relative preponderance over the other ingredients; in his words, "each one is... most manifestly those things of which there are the most in it". He introduced the concept of Nous ( Cosmic Mind) as an ordering force, which moved and separated out the original mixture, which was homogeneous, or nearly so.

Being always was, as Parmenides argues, but the differentiation of things is not an illusion but a slow transformation that does not categorically or entirely remove any particular thing from any other thing .

Fire became more distinguished, but all things contain fire and fire contains the seeds and components of all things. Through the process, fire became much more fiery than everything else, which remained far less fiery.

What is Anaxagoras' theory?
Anaxagoras developed his metaphysical theories from his cosmological theory. He accepted the ideas of Parmenides and the Eleatics that the senses cannot be trusted and that any apparent change is merely a rearrangement of the unchanging, timeless and indestructible ingredients of the universe. Not only then is it impossible for things to come into being (or to cease to be), he also held that there is a share of everything in everything, and that the original ingredients of the cosmos are effectively omnipresent (e.g. he argued that the food an animal eats turns into bone, hair, flesh, etc, so it must already contain all of those constituents within it). He denied that there is any limit to the smallness or largeness of the particles of the original cosmic ingredients, so that infinitesimally small fragments of all other ingredients can still be present within an object which appears to consist entirely of just one material (presaging to some extent the ideas of Atomism ).

For Anaxagoras, this was a purely mechanistic and naturalistic process, with no need for gods or any theological repercussions.

It is also present in some way in everything, a kind of Dualism.
Life and Writing
The Structure of Things: A Portion of Everything in Everything
- Anaxagoras’ innovative theory of physical nature is encapsulated in the phrase, “a portion of everything in everything.” Its primary expression is found in the following difficult fragment: It should be pointed out that it is rather difficult to determine what exactly Anaxagoras meant by “things.” It is tempting to view this as a theory of matter, but this would be misguided as it tends …
The Origins of The Cosmos
- Anaxagoras’ theory of the origins of the world is reminiscent of the cosmogonies that had been previously developed in the Ionion tradition, particularly through Anaximenes and Anaximander. The traditional theories generally depict an original unity which begins to become separated off into a series of opposites. Anaxagoras maintained many of the key elements of these theories, h…
Mind
- a. The Role of Mind
According to Anaxagoras, the agent responsible for the rotation and separation of the primordial mixture is Mind or nous: “And when Mind began to cause motion, separating off proceeded to occur from all that was moved, and all that Mind moved was separated apart, and as things wer… - b. The Nature of Mind
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. In one small fragment, fo…
Other Theories
- Anaxagoras’ theory of things and his postulation of Mind as a cosmic principle are the most important and unique aspects of his philosophy. 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 philosop…
