Quote by Anaxagoras: “In everything there is a portion of everything.”

This core Anaxagorean principle, 'homoeomery,' states that every substance contains elements of all other substances, albeit in varying proportions. It explains how things derive their qualities, suggesting that nothing is purely one thing, but rather a blend of all things, creating infinite diversity from a single mixture.

This concept was Anaxagoras's solution to the problem of 'how something can come from something else' without violating Parmenides' principle of no creation from non-being. It explains generation and change through the rearrangement of existing particles.

Greek philosopher from Clazomenae who lived approximately 500–428 BCE and was the first philosopher to settle in Athens. He proposed that the cosmos was organized by a divine mind (nous) and that all matter was originally mixed together before being differentiated. He was put on trial in Athens for impiety and forced into exile.
