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. Except for the second one, I don't know if they're really worth buying. But since they're unusual and, I think, somewhat original, I've provided links to free copies. Just know that my views have changed in some respects, and I find it hard even to identify now with the person who wrote the first and third books. The passage of time plays funny tricks on you.
