Given the title, I think it’s safe to use this and feel pretentious-to-the-max.
“All this has changed since I started thinking about death. And I do nothing else but sit here thinking about him. I am so entirely taken up by thinking about him that if my head were to be cut off now, my stomach or my right knee-joint would continue the work of thinking about him and would, no doubt, bring it to its proper conclusion.”
- Hans Kleison “Death of the Adversary.
On a sidenote, this book is incredible. Thank you New York Times Literature Magazine for alerting me to it.
