Central to Heraclitus' philosophical framework is the concept of the "logos," a term rich in meaning and significance.

Heraclitus introduced the notion of the "unity of opposites" in his philosophical discourse, influencing subsequent thinkers such as Hegel

At the heart of Heraclitus' philosophical worldview lies the concept of "panta rhei" or "everything flows."
