The Oxford Dictionary defines a prophet as.a person who advocates or speaks in a visionary way about a new cause or theory, a definition which describes to a tee, the set of early 20th century authors whose writings on power are presented here. In short, the early 20th century witnessed a power surge, the likes of which the world had never experienced. As power and/or energy is the basis of material civilization, it stands to reason that this surge would surely go on to revolutionize life in general.
