The only way to survive such shitty times, if you ask me, is to write and read big, fat books, you know? And I’m writing now another book on Hegelian dialectics, subjectivity, ontology, quantum physics and so on. That’s the only way to survive. Like Lenin. I will use his example. You know what Lenin did, in 1915, when World War I exploded? He went to Switzerland and started to read Hegel.
