NOTES OF AN UNDERGROUND HUMANIST
The Book Shelf
The first
The second
The third
Disclaimer: I wrote these books years ago and am now less-than-satisfied with them. But since they're unusual and, perhaps, somewhat provocative, I've provided links to free copies. Just know that in some respects they're intentionally rough, full of partially fleshed-out ideas, not "polished" (or neutered, hyper-cautious) in the typical academic way. Nor do I now agree with all the views expressed, especially in the first and third books.
