"Anaxagoras entry by Patricia Curd in the Stanford Encyclopedia of Philosophy"

“Mind is infinite and self-ruled, and is mixed with nothing, but is alone itself by itself.”

“Translation and Commentary from John Burnet's Early Greek Philosophy.”

“Thought is something limitless and independent, and has been mixed with no thing but is alone by itself. ... What was mingled with it would have prevented it from having power over anything in the way in which it does. ... For it is the finest of all things and the purest.”

“Wrongly do the Greeks suppose that aught begins or ceases to be; for nothing comes into being or is destroyed; but all is an aggregation or secretion of pre-existent things: so that all-becoming might more correctly be called becoming-mixed, and all corruption, becoming-separate.”

“The sun provides the moon with its brightness.”

“The Greeks follow a wrong usage in speaking of coming into being and passing away; for nothing comes into being or passes away, but there is mingling and separation of things that are. So they would be right to call coming into being mixture, and passing away separation.”
