This dissertation explores the notion of wise and its implications in Heraclitus, defending the hypothesis that, even though attaining such a state of wisdom may be challenging, such a possibility was conceived for all humans. The ultimate goal would be the realization of Unity – presented on fragment B 50 – and we can see in other fragments (such as B 29 and 49) that Unity was indeed considered an objective that should guide human conduct in life, in other words, it was also seen as an ethical goal. This work examines the relationship between this characteristic of unity as a paradigm and the concept of divinity that Heraclitus forms, suggesting the possibility of an identity between the divine and the human. Finally, an interpretation is proposed for the path of knowledge that Heraclitus conceives for those who seek this state, a path based on the complementary relationship between a certain notion of self-knowledge and the use of the senses.
