Eternal Recurrence and Language

One of Nietzsche's most important applications of Schopenhauer's system is not presented in any of his major works, but in his early essay 'Of Truth and Lie in an Extra-Moral Sense'.  There, he proposes that Language is no more than a social construct, a position that nowadays is classified as the 'Private Language Argument', thus predating the purported pioneering of the latter, i. e. Wittgenstein's, by several decades.  Of specific interest to Nietzsche in his subsequent works, is that this thesis entails that any verbal formulation that promotes the value of the Individual is inherently absurd, i. e. because its medium is an essentially social construct.  Thus, the target of laughter in #1 of The Gay Science, is not so much the Individual, per se, but language that attempts to isolate the Individual.  Likewise, it is as a verbal artifact that the doctrine of Eternal Recurrence, as one of self-affirmation, is perhaps parodistic, as Nietzsche suggests in the preface to The Gay Science.
