Hilarious is the idea that ἀποκαλύπτω emerged as a Greek translation in the Septuagint of the Hebrew "Gala" (Strong's concordance 1540), which is a heavily sexualized "uncovering" like in Noah's drunkenness, incest taboo in Leviticus, and intercourse in Ruth, and many other occasions: almost two hundred occurrences in the Jewish Bible.
Of revelation as transcendentally irreducible that inheres deeper than the literary genre of apocalypse even with all its rich inheritance, of the notion of tone (as opposed to the discourse or the concept, if it is nailable at all), and a tracing of the philosophical disputes in the 1980s in the 1790s (with an echo to ca. 450 B.C.). Many echoes to contemporaneous « La carte postale », « Les tours de Babel ». Text of an address at Cerisy-la-Salle to his followers. Of note are also 1) his uncovering of Aufklärung as essentially dependent on what it had been demystifying, thus enclosing any demystification in general in a repetition of the disavowed, 2) and an insistent refining of the difference between la clôture et la fin, which allows to view any teleology as a topology or a transcendental a priori, or a tendency thereof, rather than what it pretends itself. So much more of illumination here, but I'll merely adduce two quotes.
« Le rêve ou l’idéal du discours philosophique, de l’allocution philosophique et de l’écrit qui est censé la représenter, n’est-ce pas de rendre la différence tonale inaudible, et avec elle tout un désir, un affect ou une scène qui travaillent le concept en contrebande ? »
Jacques Derrida, D’un ton apocalyptique adopté naguère en philosophie (Paris: Galilée, 1983), p. 18
« Ce que veut dire le ton n’est pas forcément ce que dit le discours, et l’un peut toujours contredire, dénier, faire dériver ou dérailler l’autre ».
Jacques Derrida, D’un ton apocalyptique adopté naguère en philosophie (Paris: Galilée, 1983), p. 68–9
« Which means the tone is not perforce what the discourse says, and either one can always contradict, deny, make drift, derive, or derail the other ». Jacques Derrida, “Of an apocalyptic tone recently adopted in philosophy,” Semeia 23 (1984), pp. 63–97, the quote on p. 84
