[51] His devotion to the austere and abstract philosophy of Parmenides, its passivity or indifference, could not repress the opulent genius of Plato, or transform him into a cynic. Another ancient philosopher, Pythagoras, set the frozen waves in motion again, brought back to Plato's recognition all that multiplicity in men's experience to which Heraclitus had borne such emphatic witness; but as rhythm or melody now--in movement truly, but moving as disciplined sound and with the reasonable soul of music in it. Pythagoras, or the founder of the Pythagorean philosophy, is the third of those earlier masters, who explain the intellectual confirmation of Plato by way of antecedent. What he said, or was believed to have said, is almost everywhere in the very texture of Platonic philosophy, as vera vox, an authority with prescript claim on sympathetic or at least reverent consideration, to be developed generously in the natural growth of Plato's own thoughts. [52] Nothing remains of his writings: dark statements only, as occasion served, in later authors. Plato himself attributes those doctrines of his not to Pythagoras but to the Pythagoreans. But if no such name had come down to us we might have understood how, in the search for the philosophic unity of experience, a common measure of things, for a cosmical hypothesis, number and the truths of number would come to fill the place occupied by some omnipresent physical element, air, fire, water, in the philosophies of Ionia; by the abstract and exclusive idea of the unity of Being itself in the system of Parmenides. To realise unity in variety, to discover cosmos--an order that shall satisfy one's reasonable soul--below and within apparent chaos: is from first to last the continuous purpose of what we call philosophy. Well! Pythagoras seems to have found that unity of principle (archê)+ in the dominion of number everywhere, the proportion, the harmony, the music, into which number as such expands. Truths of number: the essential laws of measure in time and space:--Yes, these are indeed everywhere in our experience: must, as Kant can explain to us, be an element in anything we are able so much as to conceive at all. And music, covering all it does, for Pythagoras, for Plato and Platonism--music, which though it is of course much besides, is certainly a formal development of purely numerical laws: that too surely is something, [53] independently of ourselves, in the real world without us, like a personal intelligible soul durably resident there for those who bring intelligence of it, of music, with them; to be known on the favourite Platonic principle of like by like (homoion homoiô)+ though the incapable or uninstructed ear, in various degrees of dulness, may fail to apprehend it.
