While fixing our thoughts upon Pericles as the exponent of the mature spirit of free Hellas, we owe some attention to his master, the great Anaxagoras, who first made reason play the chief part in the scheme of the universe. Of the relations of Anaxagoras to his pupil Pericles, this is what Plutarch tells us: "He that saw most of Pericles, and furnished him most especially with a weight and grandeur of sense superior to all arts of popularity, and in general gave him his elevation and sublimity of purpose and of character, was Anaxagoras of Clazomenæ, whom the men of those times called by the name of Nous--that is, mind or intelligence; whether in admiration of the great and extraordinary gift he displayed for the science of nature, or because he was the first of the philosophers who did not refer the first ordering of the world to fortune or chance, nor to necessity or compulsion, but to a pure, unadulterated intelligence, which in all other existing mixed and compound things acts as a principle of discrimination, and of combination of like with like." Thus we may say, without mysticism, that at the very moment in history when the intelligence of mankind attained to freedom, there arose a philosopher in Anaxagoras to proclaim the freedom and absolute supremacy of intelligence in the universe; and a ruler in Pericles to carry into action the laws of that intelligence, and to govern the most uncontrollably free of nations by reason. When Pericles died, Athens lost her Zeus, her head, her real king. She was left a prey to parties, to demagogues, to the cold encroaching policy of Sparta. But Pericles had lived long enough to secure the immortality of what was greatest in his city--to make of Athens in her beauty "a joy forever."
