Charles Darwin threw out the god fairy fantasy but he didn't want to write about it. He said nothing about the Magic Man in his numerous books. "Freedom of thought is best promoted by the gradual illumination of men's minds, which follows from the advance of science." -- Charles Darwin

"Though I am a strong advocate for free thought on all subjects, yet it appears to me (whether rightly or wrongly) that direct arguments against Christianity & theism produce hardly any effect on the public; & freedom of thought is best promoted by the gradual illumination of men's minds, which follows from the advance of science. It has, therefore, been always my object to avoid writing on religion, & I have confined myself to science. I may, however, have been unduly biased by the pain which it would give some members of my family, if I aided in any way direct attacks on religion."
