Reason about the world and sense of existence in the Heraclitus' thought

The interpretation of Heraclitus' thought in an existentialistic way is based on the analysis of the relationship between physis and logos. If concept of physis has to be understood as an incessant process, on the other side, logos has to be conceptualized as the correct meditative attitude that man has to adopt in front of the physis to bring out its truth (aletheia). The responsibility of man, as bearer of the logos, has so to configure the meaning of the reality, and his life too.
