I'm glad you like the recommendations. I am not an expert in these fields. If you find any books that you find interesting I would be interested in knowing about them. Discussing these ideas is the only way I really come to understand them. I usually use my real name in forums, but when I started my account on LitNet I was undecided, wondering if that was a good idea. That is why I picked YesNo, a sign of indecision. I will look for the Celan poem. The idea of keeping yes and no "unsplit" sounds interesting.
I'll be looking into the books you referenced; appreciate the recs! Is your username a reference to Paul Celan's poem 'Speak You Also'? The line, 'keep yes and no unsplit,' keeps coming to mind when I see your comments...
