Although he does not speak in detail of his political views in the extant fragments, Heraclitus seems to reflect an aristocratic disdain for the masses and favor the rule of a few wise men, for instance when he recommends that his fellow-citizens hang themselves because they have banished their most prominent leader. Heraclitus' criticisms and metaphysical speculations are grounded in a physical theory. He expresses the principles of his cosmology in a single sentence: .
"This world-order, the same of all, no god nor man did create, but it ever was and is and will be: everliving fire, kindling in measures and being quenched in measures."".
Heraclitus views the soul as fiery in nature: .
"To souls it is death to become water, to water death to become earth, but from earth water is born, and from water soul."".
Soul is generated out of other substances just as fire is. However, it has a limitless dimension:.
"If you went in search of it, you would not find the boundaries of the soul, though you traveled every road-so deep is its measure- .
Heraclitus goes beyond the natural philosophy of the other Ionian philosophers to make profound criticisms and develop far-reaching implications of those criticisms. He suggests the first metaphysical foundation for philosophical speculation, anticipating process philosophy. Moreover, he makes human values a central concern of philosophy for the first time. His aphoristic manner of expression and his manner of propounding general truths through concrete examples remained unique.
Parmenides.
Parmenides, son of Pyres, was a citizen of Hyele, Elea, or Velia; a colony founded in Oenotria by refugees from Phocia in 540-39 B.C. Diogenes tells us that he "flourished" in 01. LXIX. (504-500 B.C.), and this was doubtless the date given by Apollodorus. On the other hand, Plato says that Parmenides came to Athens in his sixty-fifth year, accompanied by Zeno, and conversed with Socrates, who was then quite young.
