I think I've chosen the title accordingly, for it's Nietzsche's style of eminently personal writing that interests me. A certain indelible mark of subjectivity that permeates everything he conceived. But there's something more—the very way in which we wrote, the epigrammatic deliveries, the bits, the chops, the fragments, the inherently aphoristic manner, the propensity for maxims, for terse and stark utterances. It must be something highly anti-sistematic. Something that resembles pieces of chaos put together in a book than an inflexible system. Always polemical. Witty, subversive, subtle, intelligent—and, quoting Barthes, someone that can offer pleasure, that's how I want this writer! So, who's going to be then?
Schopenhauer? Pascal ? Montaigne ? Lichtenberg ? La Rochefoucauld, Vauvenargues, Joubert, Chamfort, that is, the French moralists whom Nietzsche so dearly adored? Gracian? E. M. Cioran (he's the closest in terms of chronology)? Roland Barthes ? Walter Benjamin? Theodor Adorno ? Kierkegaard ? Heraclitus ? Valéry ? Bataille ? Shestov ? Benjamin Fondane ?
I know these. I've read them. They're very much akin to Nietzsche.
But there's got to be more of them! To be fair, I'd prefer someone more contemporaneous like Barthes, Benjamin and Cioran than the Greeks or some renaissance scribbler, but...
I'm very sorry to have omitted Wittgenstein and Leopardi—two great writers who had no notions of a coherent system. The first, subtlety itself, the second, one of the gravest writers Europe has ever produced.
