In The Clouds Socrates conducts a psychic investigation with the subject lying on a couch attempting free association. In The Wasps a therapy identical to psychodrama is portrayed. The author calls these plays the origins of psychoanalysis and psychodrama respectively, on the sole apparent basis of their having long preceded the works of Freud and Moreno. Another instance of post hoc reasoning is found in the contention Aristophanes liberated himself of wrath and aggression in writing The Wasps inasmuch as subsequent plays are filled with joy and affection.
