Enigma is a short allegorical story that speaks of a certain type of insanity that affects the minds of those who, believing that they, and they alone, are capable of revealing the truth - the sole truth - engage in actions that lead humanity to the brink of the abyss. In this sense the book speaks of science and religion as being one. Enigma, as the title suggests, is a highly enigmatic tale, being also a sequel to the author's equally enigmatic book entitled A Tale of Two Deserts. This latter book, taken with Enigma, creates a single narrative about a folly so great that it threatens humanity's future, yet people are blind to this even though the evidence for such is all around: as the book says, "Nature dies before us, yet few notice this." And the book contains a message that this does not have to be so and what we need to do is to acquire the knowledge, the sophistication and the wisdom to reap the benefits from religion and science without these things destroying us.
