 LaVey explains his reasons for writing The Satanic Bible in a short preface. He speaks skeptically about volumes written by other authors on the subject of magic, dismissing them as "nothing more than sanctimonious fraud" and "volumes of hoary misinformation and false prophecy." He complains that other authors do no more than confuse the subject. He mocks those who spend large amounts of money on attempts to follow rituals and learn about the magic shared in other occult books. He also notes that many of the existing writings on Satanic magic and ideology were created by "right-hand path" authors. He tells that The Satanic Bible contains both truth and fantasy, and declares, "What you see may not always please you, but you will see!"
