This story centers on the invention of a reactor that can annihilate matter to produce cheap and abundant energy. Unfortunately, it produces something else as a by-product, the absolute. The absolute is a spiritual essence that according to some religious philosophies allegedly permeates all matter. It is associated with human religious experience, as unsuspecting humanity is to find out all too soon in the story. The widespread adoption of the reactors causes an enormous outpouring of pure absolute into the world. This leads to an outburst of religious and nationalist fervor, causing the greatest, most global war in history. R. D. Mullen called the novel "one of the genuine masterpieces of SF," but noted that due to its originality "it has surely had no great influence on popular SF."
