'Debt to the situation translates into a sense of "responsibility," like the artist who today finds him/herself in the midst of capitalism in crisis - nothing new there! - and is compelled to make art out of a sense of pathos and guilt rather than affirmation.'
Of course this is, for them, a bad thing. It's not just deliberate perversity, although that may play a part, but what's so wrong about a sense of 'responsibility' (and why the scare quotes?) and making art out of a sense of pathos and guilt? Less in favour of pathos, but guilt would be fine. Also, capitalism in midst of crisis is nothing new, well not in the technical sense but isn't this a slightly larger crisis? (perhaps leave this to Paul Mattick).
Of course I've written at length critically about affirmation, but even if one is affirmative I think the unspoken obviousness that is implied here might need a little more justification. Simply to mention 'responsibility', 'pathos' or, even worse, 'guilt', is supposed to raise post-Nietzschean hackles like an inbuilt-reflex (never made the maudlin pathos of much of Nietzsche and Nietzschean - all heroic strength while complaining about being 'dragged down' by those evil Christian / socialist / anarchist masses...).
