"Herakleitos speaks of "wisdom" or the "wise" in two senses. ...[H]e said wisdom was "something apart from everything else" (fr. 18), meaning ...the perception of the unity of the many ...[H]e also applies the term to that unity... regarded as the "thought that directs the course of all things." This is synonymous with the pure fire which is not differentiated into two parts, one taking the upward and the other the downward path. That alone has wisdom; the partial things we see have not. We ourselves are only wise in so far as we are fiery (fr. 74)."
