I have imagination but I don't believe that everything I imagine or dream is real. For instance when I watch "X-Files" or "Lord Of The Rings" I don't think that that is realty, that's the difference. Knowing line between imagination and reality does not mean not having imagination.
teachings of the Bible are so muddled and self-contradictory that it was possible for Christians to happily burn heretics alive for five long centuries. It was even possible for the most venerated patriarchs of the Church, like St. Augustine and St. Thomas Aquinas, to conclude that heretics should be tortured (Augustine) or killed outright (Aquinas). Martin Luther and John Calvin advocated the wholesale murder of heretics, apostates, Jews, and witches. - Sam Harris, "Letter To A Christian Nation"
