Hmmmmmm.
I even gave my set of GREAT BOOKS away.
I thought James had some very useful insights. He was more kindly toward spiritual issues than a lot of other elites.
Whitehead . . . dredging up faint memories . . . Certainly a deep thinker . . . guess I ended up classing him along with a lot of folks who have a lot of pontifical, sometimes very insightful things to say about life and reality but who have missed it too wholesale vis a vis the God of The Bible for me to belabor them much. But I really don't remember anything specific about my Whitehead reading.
Whitehead is not easy. I have one of your Great Books--Plotinus. If you can read Plotinus you can read Whitehead. Whitehead, BTW, started his philosophy with God and built downward, as did Plotinus although he was kind of before Christianity.
