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.
Frag. B 17, quoted in John Burnet's Early Greek Philosophy, (1920), Chapter 6.
The sun provides the moon with its brightness.Anaxagoras
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 preexisting things; so that all becoming might more correctly be called becoming mixed, and all corruption, becoming separate.Anaxagoras
All things were together, infinite both in number and in smallness; for the small too was infinite.Anaxagoras
And since these things are so, we must suppose that there are contained many things and of all sorts in the things that are uniting, seeds of all things, with all sorts of shapes and colours and savoursAnaxagoras
Mind is infinite and self-ruled, and is mixed with nothing, but is alone itself by itself.Anaxagoras
