one may better perceive the invisible, but more probably means to close the lips while the soul is brooding over what cannot be uttered. Later Christian admirers said of him, that he had hidden the words of God in his heart. The dust of his golden verses perhaps, but certainly the gold-dust of his thoughts, lies scattered all along Greek literature from Plato to the latest of the Greek Fathers of the Church. You may find it serviceably worked out in the notes of Zeller's excellent work on Greek philosophy, and, with more sparing comment, in Mullach's Fragmenta Philosophorum Graecorum. No one of those Pre-Socratic philosophers has [59] been the subject of a more enthusiastic erudition. For his mind's health however, if in doing so he is not making a disproportionate use of his time, inconsistent certainly with the essential temper of the doctrine he seeks for, and such as a true Pythagorean would instantly condemn, the young scholar might be recommended to go straight to the pages of Aristotle--those discreet, unromantic pages, salutary therefore to listen to, concerning doctrines in themselves so fantastic.* In the Ethics, as you may know, in the Metaphysics, and elsewhere, Aristotle gives many not unsympathetic notices at least of the disciples, which, by way of sober contrast on a matter from the first profusely, perhaps cheaply, embroidered, is like quiet information from Pythagoras himself. Only, remember always in reading Plato--Plato, as a sincere learner in the school of Pythagoras--that the essence, the active principle of the Pythagorean doctrine, resides, not as with the ancient Eleatics, nor as with our modern selves too often, in the "infinite," those eternities, infinitudes, abysses, Carlyle invokes for us so often--in no cultus of the infinite (to apeiron) but in the finite (to peras).+ It is so indeed, with that exception of the Parmenidean sect, through all Greek philosophy, congruously with the proper vocation of the [60] people of art, of art as being itself the finite, ever controlling the infinite, the formless. Those famous systoichiai tôn enantiôn,+ or parallel columns of contraries: the One and the Many: Odd and Even, and the like: Good and Evil: are indeed all reducible ultimately to terms of art, as the expressive and the inexpressive. Now observe that Plato's "theory of ideas" is but an effort to enforce the Pythagorean peras,+ with all the unity-in-variety of concerted music,--eternal definition of the finite, upon to apeiron,+ the infinite, the indefinite, formless, brute matter, of our experience of the world.
