Dear Rose Bowl,are you referencing Aleister Crowley in your title - (I am currently reading his bio) or are you talking about that Lawrence Krauss guy or..
Hello Little Bull - Carl Sagan, actually, referenced in a story about SETI... scanning the universe for signs of life. Aleister Crowley, though... I have "Diary of a Drug Fiend" in my bookshelf. Need to spend some time with that.
