Quotes about Heraclitus 34 Sourced Quotes
The followers of Heraclitus insisted the Immortal Principle was change and motion. But Parmenides' disciple, Zeno, proved through a series of paradoxes that any perception of motion and change is illusory. Reality had to be motionless. The resolution of the arguments of the Cosmologists came from a new direction entirely, from a group Phædrus seemed to feel were early humanists. They were teachers, but what they sought to teach was not principles, but beliefs of men. Their object was not any single absolute truth, but the improvement of men. All principles, all truths, are relative, they said. "Man is the measure of all things." These were the famous teachers of "wisdom," the Sophists of ancient Greece. Not only the Greeks in general — Aristotle no less than Plato — but the great medieval thinkers as well, all held that there was an element of purely receptive "looking," not only in self-perception but also in intellectual knowing or, as Heraclitus said, "Listening-in to the being of things." The medievals distinguished between the intellect as ratio and the intellect as intellectus. Ratio is the power of discursive thought, of searching and re-searching, abstracting, refining, and concluding [cf. Latin dis-currere, "to run to and fro"], whereas intellectus refers to the ability of "simply looking" (simplex intuitus), to which the truth presents itself as a landscape presents itself to the eye.
