Previous editions, however, have been difficult theoretical treatises. Now the fourth edition of World History And The Eonic Effect simplifies the considerable amount of historical theory present in earlier versions. This dose of theory made the eonic effect seem a speculative construct, when the object of the exercise is to approach the question of evolution empirically. This theory, the so-called 'eonic model', has been streamlined so that the main emphasis in the text is on a simple outline of world history. As we explore this outline the contours of the eonic effect stand out as an empirical given of historical evidence. The failure to grasp that world history itself shows us the solution to the evolution enigma is due to the ideological control exerted over the key incidents that show what is going on, such as the Axial Age. This evidence has been ignored or distorted and fails to register with students of standard histories. The dogma that world history follows some kind of Darwinian logic is hopelessly flawed, and the evidence points directly to a hidden process of macroevolution behind the sequence of events. In fact world history shows an elegant unity in diversity, and a logical dynamics that stands out once we apply a consistent strategy of periodization.
