The universality of the law of History. The law of History governs the process in all domains of human activity.� Nations evolve, progress, decline and rise again, following some perfect cycles in the political, social, artistic, philosophical and scientific arenas. Nothing is the work of chance. The appearance and disappearance of great empires, the creation of architectural styles, the great discoveries, the great philosophical conceptions, obey a mechanism that is as precise as a clock. Up to now men have ignored it. Some have suspected it but up to now nobody had defined it. For this reason, men and nations have been following a road that, unknown to them, was traced beforehand.� Declarations of the mathematical law that determine the evolution of nations: We can resume that law in the following paragraphs:� 1. All nations go through eras of Great Demographic Fractionation, alternating with other of Great Unification or imperialist eras.� 2. Eras of Great Fractionation have a duration of six and one-half centuries. Eras of Great Unification last ten and one-half centuries. The cycle of evolution is made up of seventeen centuries.� 3. During this process of evolution, nations go through perfectly established phases so that at the end of the cycle they occupy the same position it had at the beginning thereof. 4. The cycle of evolution covers all areas of human activity, that is, in addition to the political cycle, we must consider the social, artistic, philosophical and scientific ones. 5. All nations follow the same evolution, but it is ahead or behind, according to the geographical position of each country.� 6. The creative force is not the same for all nations. 7. Imperialist nuclei that give way to eras of Great Political Unification, follow perfect biological processes that are identical to each other and with one same longevity that lasts from five to six centuries. 8. The transformation of political-social regimes is not done according to a constant ascending or descending line, but through alternative advances or reversals, some more intense than others, that produce a broken line as a result. The result of this line is equivalent to an advance in a determined sense. This is given the name of �Law of two paces towards the front and one towards the back� or �Oscillating Law�. We are going to precisely determine and explain these paragraphs through a graphical representation of the evolutionary cycle. If in a system of Cartesian Coordinates we mark time over the X axis (horizontal axis) and the changes nations go through, from every point of view of human activity, over the Y axis (vertical axis), we can represent the evolutionary process thereof, as seen in Chart 1.�
