Who has one voice and yet becomes three-footed and two-footed and four-footed? Sophocles’ Oedipus, the most suffering figure of the Greek tragedy. Oedipus crawled on three as a baby (because his ankles were pinned together by his parents who abandoned him), limped as an adult, and walked on four legs as an old man (blinding himself after he learnt that he killed his father and married his mother, he is led by his daughter Antigone).
As fate would have it, he got to his destiny by solving the riddle of the Sphinx: which creature has one voice and yet becomes four-footed and two-footed and three-footed? If Oedipus grasped the riddle’s irony, he would recognize that he is the exact opposite of “human”, who should be ignorant. Wisdom is an unnatural abomination. Nietzsche saw it in the terrible trinity of Oedipus’ fates: the same man who solves the riddle of nature must also destroy the orders of nature by murdering his father and marrying his mother.
Sophocles’ closing line of the play is more eloquent yet: “Do not seek to be master in everything, for the things you mastered did not follow you throughout your life.” Given that we want to be wise, why do we not prefer to be ignorant?
