This is a (debatable) list of the various conflicting motifs and themes of Tragedy and Comedy.

Comedy Tragedy
More flexible and adaptive Understands life in "good/evil" and acts straight forwardly
Highly disordered, plot can seem random, like real life Little disorder, structured plot
Lots of ambiguity, the unfamiliar Prefers familiar things, little ambiguity
More playful and imaginative Less playful, more serious
