Nietzsche:

“I will not say that the tragic world-view was everywhere completely destroyed by this intruding un-Dionysian spirit: we only know that it had to flee from art into the underworld as it were, in the degenerate form of a secret cult.” [1]

Nandita Biswas Mellamphy:

 “I would suggest that the Nietzschean Übermensch, though framed within the language of type and typology, should be approached not from a juridical framework that sets out formal ideals to be followed, but as a choreographic manner for tracking the physiological movements inscribed within the overhuman background of the living medium (or ‘life’). Recalling Nietzsche’s statement regarding the aesthetic justification of life in The Birth of Tragedy, the human becomes visible (Apollo) only as the aesthetic expression of overhuman primordiality (Dionysus); the human is only a surface of inscription for the overhuman.” [2]
