Heraclitus

Heraclitus (c. 535–475 BCE)

Known for his doctrine of change and the unity of opposites, Heraclitus proposed that reality consists of constant flux, symbolized by the interplay of opposites (such as fire and water).

Interaction with Pythagorean Ideas

Although Heraclitus did not adopt a strict numerical structure, his focus on the balance and transformation of opposites resonates with Pythagorean themes of harmony within diversity. His idea that opposites form a unified whole indirectly complements the three-in-four logic by suggesting that the interaction of forces culminates in a balanced, dynamic unity.
