"Levenda's study is broad and deep, a life's work that runs to volumes. What distinguishes it from other efforts, such as those of Pasolini, is not merely its comprehensiveness. Rather, it is Levenda's realization that a matrix of politics and violence is incapable of explaining the demented century that shuddered to an end in Manhattan, not so long ago. What's needed is a third dimension, and that dimension, he tells us, is "the occult." By this, Levenda means something broader than a mix of magic and religion. When he writes of the occult, he means to include whatever is secret, hidden, or unknown. Add this dimension to those of politics and violence, and the century shivers into focus. Sinister Forces is about evil in what is now the digital age: Evil 2.0."
