Cyberpunk is '40s noir films, jaded cynicism and nihilism.
The emo frame of mind would be a lazy form of nihilism, were it not too lazy to pick up a copy of Turgenev and make the correlation.
He followed it up with a number of other works on the condition of the Russian peasantry, on Nihilism, and on the conditions of life in Russia.
Still more unequivocal was the sceptical nihilism expressed by Gorgias: - (I) nothing exists; (2) if anything existed, it would be unknowable; (3) if anything existed and were knowable, the knowledge of it could not be communicated.
The principle of examination, the reasoned analysis of human conditions and the discussion of causes, far from culminating in disillusioned nihilism, everywhere aroused the democratic spirit, the life of sentiment and of human feeling: in the drama, with Marivaux, Diderot and La Chausse; in art, with Chardin and Greuze; and in the salons, in view of the suppression of privilege.
