In this paper, the author thoroughly discussed the gnoseological radiation of Nietzsche's Thus Spoke Zarathustra, placing this famous book in the context of epochal and revolutionary topics of this philosopher, from the will for power, overman, through death of God, antipodal tension between the Apollonian and the Dionysian principle of the being, to eternal recurrence of the same. Criticising those anthropological and epistemological interpretations which trivialise the semantic dimension of this jagged and unapproachable work of Nietzsche, the author of the text submits those arguments which illuminate a quite distinctive hermeneutical approach to the nihilistic philosophy of this great German thinker, while at the same time pointing out his 'singing and thinking' for sophisticated understanding of contemporary postmodern situation. Within the globally dominant ideologies, ending with the liberal-democratic and neoliberal, an ontological decision on cultural and personal choice of the masking existence strategy to escape from finitude is founded. Nietzsche's anticipation, according to the author's explanation, reached up to the present moment in which, thanks to the technological, media and information evolution, the autonomous capacity of products originally intended for the total dismissal of the authentic ontological ambience remains such that it becomes active in terms of surveillance of human users. Postmodern reality - observed from the point of view of Nietzsche's insight from the book Thus Spoke Zarathustra - has turned into administrative instance, so far as man has become totally dependent on its maintenance, since he reached the point of leaving himself alone.
