Heraclitus, a writer of philosophy in prose, yet of a philosophy which was half poetic figure, half generalised fact, in style crabbed and obscure, but stimulant, invasive, not to be forgotten--he too might be thought, as a writer of prose, one of the "fathers" of Plato. His influence, however, on Plato, though himself a Heraclitean in early life, was by way of antagonism or reaction; Plato's stand against any philosophy of motion becoming, as we say, something of a "fixed idea" with him. Heraclitus of Ephesus (what Ephesus must have been just then is denoted by the fact that it was one of the twelve cities of the Ionian League) died about forty years before [13] Plato was born. Here then at Ephesus, the much frequented centre of the religious life of Ionia, itself so lately emancipated from its tyrants, Heraclitus, of ancient hereditary rank, an aristocrat by birth and temper, amid all the bustle of still undiscredited Greek democracy, had reflected, not to his peace of mind, on the mutable character of political as well as of physical existence; perhaps, early as it was, on the mutability of intellectual systems also, that modes of thought and practice had already been in and out of fashion. Empires certainly had lived and died around; and in Ephesus as elsewhere, the privileged class had gone to the wall. In this era of unrestrained youthfulness, of Greek youthfulness, one of the haughtiest of that class, as being also of nature's aristocracy, and a man of powerful intellectual gifts, Heraclitus, asserts the native liberty of thought at all events; becomes, we might truly say, sickly with "the pale cast" of his philosophical questioning. Amid the irreflective actors in that rapidly moving show, so entirely immersed in it superficial as it is that they have no feeling of themselves, he becomes self-conscious. He reflects; and his reflexion has the characteristic melancholy of youth when it is forced suddenly to bethink itself, and for a moment feels already old, feels the temperature of the world about it sensibly colder. Its very ingenuousness, its sincerity, will make the utterance of what comes [14] to mind just then somewhat shrill or overemphatic.
