The Noble Lie and the Naked Emperor.

In Plato's discussion of the 'Noble Lie', the falsehood is known to only the Liar.  Part of Nietzsche's historical significance is theat he, perhaps uniquely, tackles the problem of the exposure of the Noble Lie.  What he wrestles with in his mature period is the profound corrosiveness of the discovery that the 'Emperor is naked', i. e. the discovery that 'God is dead' undermines the institution of any substitute Noble Lie, and, therefore, threatens to undermine any basis for future civilization.  In other words, that exposure initiates an era of what he calls 'Nihilism', which he can combat only ironically, given that his own words--the teachings of Zarathustra, the Will to Power, evaluations, the  formulation of 'Atheism', and even the thesis that civilization needs no myth--are as suspect as the expired ideology.  So, the development of that Nihilism exemplifies what has here been characterized as the process in which Lying undermines Communication, and which Kant glosses as the contradictoriness of False Promising.
