George Gaylord Simpson (birth: June 16, 1902 – Death: October 6, 1984) was one of the most influential American paleontologists of the twentieth century and a major participant in the modern evolutionary field.
If I didn't fear I'd do you harm...I'd try to make you [Anne] an atheist. I really do think that you are a deluded follower of mistaken and superstitious & cowardly theories. That's as far as I'll go....Everyone who worships a god worships a force back of all nature, no matter what they call him or it and even if they call his aspects by different names & have many "gods." If there really is such a force, then all people who worship any god or gods, worship the same god. I'd just as soon call him Ishtar or Baal or Jehovah. They're merely names for the same idea.
