Paine, Twain & Ingersoll.
Freethought needs a step-ladder?
@atheist I'm really ignorant when it comes to this stuff. I say read everything you can, if that's your thing. Mark Twain is always raucous. I've never heard of Paine before. He wasn't an atheist. Ingersoll sounds the most interesting to me. My father was a minister as well. Thanks for the leads.
