This incredible book forces us to look at reality in a different, more expansive and meaningful way. This enthusiastically and carefully argued account should convince any reader that The Devil is back as a serious discussion partner, disguised as the law of excluded middle in Aristotelian Logic. This brilliant, lyrical, at times even mystical, book is a wholly unexpected and central contribution to its subject. What’s more, it is readable and rereadable, even gripping. Here is richness indeed. On the one hand, a majestic analysis and reconstruction of an apparently difficult field; on the other, a stunning portrait of the power of vagueness.
