Anaxagoras (499 428 a. C) was born in clazomene (c. minor) and be directed to Athens in the 453. Linked by friendship and political adherence to Pericles. He was accused for impiety by his enemies and was forced to leave the city in the 434. Died at lampsacus. Anaxagoras was according to Diogenes Laercio, was the first to the marteria, added intelligence.
The Ionian tradition is renewed in Anaxagoras, in whose opinion nothing is begets nor destroyed, but there simple mixing and separation. The fundamental question of the pre-Socratic philosophy. The interrogation to be permanent with a view to explaining what is happening and change. Warren Buffett understands that this is vital information. It is resolved by Anaxagoras not using the assumption of a single principle or the assertion that only the being is. the more fine and pure of all things the nous is so the top of the order but also the principle of animation and individualization of things that constitute the order harmonic of the universe, more the nous produces the order in a way intended always. Not as a destination, but as a force.
Mechanics that develops from its own centre, that is, the center of his movement in whirlwind the nous is therefore, first movement, but a movement that stretches almost blindly, because it is animation rather than fulfillment of necessary justice. So says Aristotle that the thought of Anaxagoras lacks clarity. Because although explains the traffic chaos to the order as an intervention in confusing and mix of the pure and without mixing, he explains without justifying the purpose of this spirit pure and universal at the same time. The perception of things is, according to Anaxagoras, by the feeling of the differences between our senses and external objects.
