In unrelated news, been reflecting on The Making of Buddhist Modernism:
By arguing that developments are Buddhism don’t occur in the original Pali cannon, makes me wonder if McMahan is Theravada Buddhist. The idea that there could be developments outside the Buddha—well, maybe they’re not enlightened developments, who knows. Great sages like Milarepa and others seem have great spiritual depth.
The Boddhisattva idea—is that a new creation, or just an articulation of a reading of the Buddha’s life? Freud wrote a bunch of pregnant statements that have been developed by the community of psychoanalysts. There are many that have gone by the wayside. There was actually a book on the techniques involved in sleeping with your patient. That one fell by the wayside because the community of psychoanalyst decided it was misguided. Maybe Thich Nhat Hanh has developed “interbeing” in a way that really wasn’t in the early texts, but his bona fides as a monk are pretty good, he's connected to his community and friends, and maybe it's a useful modern Buddhist idea.
