Dissonance and Sexuality

The logical principle that an 'Individual' is always an individual of some universal corresponds to Nietzsche's thesis that the Apollinian principle always correlates to the Dionysian.  But, as his derivation of the artistic Dionysian from the Dionysian festivals is a reminder that underlying both Logic and Aesthetics is the Biology of the Individual--that the embodiment of these dualities is the reproductive organs of every apparently discrete member of a species.  In other words, when Nietzsche observes, in #25 of Birth of Tragedy, "dissonance become man--and what else is man?", the tension underlying that Dissonance is that between certain processes qua privately pleasurable and/or painful, and those same processes qua phases of the reproductive drive of the species, a tension over which the currently popular term 'sexuality', tends to gloss, i. e. as what Schopenhauer and Nietzsche would likely agree is a mere appearance.
