✅ Biography of Anaxagoras

The exact chronology of Anaxagoras is unknown , but most accounts place his life dates between 500 and 428 BC. Anaxagoras was born in Ionia , in the city of Clazomenae, a port city on the coast of present-day Turkey . As such, he is considered the geographical and theoretical successor to the early Ionian philosophers , particularly Anaximenes . Eventually Anaxagoras made his way to Athens and is often credited with making it the home of philosophical speculation andwestern physics . Anaxagoras remained in Athens for some thirty years, according to most accounts, until he was accused of impiety and sentenced to death . Instead of enduring this grief, Anaxagoras, with the help of his friend and student, Pericles , went to Lampsacus, in Asia Minor, where he took refuge and lived until his death.

Anaxagoras thought

His thinking was based on the belief he had that almost all things made up of similar parts , that these parts were not subject and that, on the contrary, everything was mixed, with the exception of intelligence , since this was pure and without mix . He believed in the principle of unity and the indeterminate . His great contribution through philosophical thought was having introduced the Nous into the explanation of the universe as a motive force that moved everything that existed. This entity known as Nous was above all, it was infinite and autonomous and could not be mixed with anything.


Anaxagoras theory conceives the nous as the only origin of the universe and as the cause of existence , trying to explain the everyday things that occur in the world. On the other hand, he made part of his explanation of reality to the concept of nous or intelligence , which, being an extremely subtle “fluid”, is achieved by filtering between matter causing it to achieve movement. The nous manages to enter some things and not others, and with this theory it manages to explain the existence and origin of animate and inert objects .

Contributions of Anaxagoras

The ideas that Anaxagoras inherited from us are based on the idea of ​​the infinite , which exists in all things, the need for men to acquire intelligence in order to introduce order into the indefinite through movement and impersonal character. of universal intelligence , of which all understandings are a part. The principle, conceived by Anaxagoras , is a moving soul of the world that works by a series of mechanical effects . The moral doctrine that Anaxagoras gave us is reduced to these two points: the contemplation of nature, and resignation to the general order. of the world.


His arche was based on the existence of a great multitude of seeds in all things. The difference between the things that exist is in the spermata or in the seeds which marked a limit in the history of philosophy .


  • If you cheat on me once, it’s your fault; if you fool me two, it’s mine.
  • The intelligence is the purest of all things. He has a total knowledge of everything and is the maximum force.
  • The spirit rules the universe.
  • Intelligence knows all things and ordered all the things that are going to be and those that were and those that are now and those that are not.
  • It is necessary to suppose that in everything that is combined there are many things of all kinds, and seeds of all things, that have different shapes and different colors and flavors.


The most important work of Anaxagoras was Peri physeos , whose meaning is ” On nature “, however, only a few fragments have managed to be rescued and have lasted throughout time. He did research about nature based on experience, memory and technique. Through his works he explained the eclipses and the respiration of fish and about the anatomy of the brain .
