Interpretations of Heraclitus by Plato and Aristotle

Plato and Heraclitus: Plato interpreted Heraclitus's teachings as emphasizing the constant state of flux in the material world. Heraclitus's famous idea that "you cannot step into the same river twice" suggested to Plato that sensory knowledge is unreliable because the objects of sense perception are in perpetual change. This view plays a significant role in Plato's theory of Forms, in which he posits that true knowledge cannot be derived from the ever-changing material world but only through the unchanging and eternal Forms.

Plato often referenced Heraclitus to highlight the instability and imperfection of the material world in contrast with the stable and perfect world of Forms. In his dialogue "Cratylus," he attributes the impossibility of knowledge in a constantly changing world to Heraclitean thought (Plato and Aristotle: ancient philosophical influences).

Aristotle and Heraclitus: Aristotle's engagement with Heraclitus was slightly different. While Aristotle acknowledged the significance of change as described by Heraclitus, he criticized the doctrine for implying that all change is chaotic and lacks regulation. Aristotle believed that this interpretation missed the organized and purposeful nature of change in the universe.

In his works, Aristotle viewed Heraclitus as a natural philosopher concerned primarily with the observable phenomena of change and opposed him with his own principle of "substance," which maintains its identity through change. Aristotle sought to provide a more structured explanation of change that included an underlying substance that persists through various forms (Heraclitus - Stanford Encyclopedia of Philosophy).
