Carroll is an atheist[5] and "hardened skeptic" (one "who has strong disbelief about all things occult"). Carroll states that the book is not meant to present a balanced view on occult subjects — it is intended to be a small counterbalance to the voluminous occult and paranormal literature.[6]
The articles in the book are in several categories:
Print versions are available in English, Estonian, Japanese, Korean, and Russian.[7] Numerous entries have been translated for the Internet in several other languages. A newsletter[8] keeps interested parties up to date on new entries and an archived list of previous newsletters is available for online perusal. Norcross et al. state that Carroll has made considerable progress in exposing pseudoscience and quackery.[9][verification needed]
According to the author,
- “The Skeptic’s Dictionary is aimed at four distinct audiences: the open-minded seeker, who makes no commitment to or disavowal of occult claims; the soft skeptic, who is more prone to doubt than to believe; the hardened skeptic, who has strong disbelief about all things occult; and the believing doubter, who is prone to believe but has some doubts. The one group this book is not aimed at is the 'true believer' in the occult. If you have no skepticism in you, this book is not for you.”
Carroll defines each of these categories, explaining how and why, in his opinion, his dictionary may be of interest, use, and benefit to each of them. He also defines the term “skepticism” as he uses it and identifies two types of skeptic, the Apollonian, who is “committed to clarity and rationality” and the Dionysian, who is “committed to passion and instinct.” William James, Bertrand Russell, and Friedrich Nietzsche exemplify the Apollonian skeptic, Carroll says, and Charles Sanders Peirce, Tertullian, Søren Kierkegaard, and Blaise Pascal are Dionysian skeptics.[10]
The New Scientist review of the paperback version commented that "It is an amazing assembly, elegantly written and level-headed, with a wry remark here and there." and that "This superb work is likely to be used so often that it is a pity it is a softback book.".[2]
