For reading alongside Pierre Hadot’s texts, I recommend Alexander Nehamas’ The Art of Living, which has similar concerns about how to practise a philosophical life, rather than casually reading philosophy for intellectual pleasure or posture. In a brilliant pair of chapters about Platonic and Socratic irony, he quotes Muecke (below), a couple of sentences that capture so concisely the hubris of many (contemporary) politicians and intellectuals (pseudo):
The typical victim of an ironic situation is essentially an innocent. Irony regards assumptions as presumption and therefore innocence as guilt. Simple ignorance is safe from irony, but ignorance compounded with the least degree of confidence counts as intellectual hubris and is a punishable offence.
