�The conclusions of the Mathematics of History are totally opposed to those of the historians and philosophers who have preceded us� exposes Dr. Deulofeu. �Humanity does not follow a constantly ascending road, it instead follows an oscillating process; these oscillations lead to the creation of great civilizations that fall in order to be substituted by other new ones and that they are not developed arbitrarily or have a variable duration, but rather appear at the precise moment, and develop following the same phases, employing therefor the same space of time, that there is nothing indeterminate in the human process but everything obeys a mathematical precision. That humanity does not progress but simply goes through phases of maximum civilization followed by others of minimum civilization and so forth, notwithstanding that between these peaks and valleys remarkable differences are indicated where the degree of progress and culture is concerned�.����������� As a point of departure, thinkers had taken the most changeable character of these civilizations, that is, its soul and culture, and the conclusion had been that instead of reaching a total synthesis, they had done it to get the opposite result, as Dr. Deulofeu has proven in his complete work of the mathematics of history (24 volumes), still not published, placing in chronological order the historical facts of the different nations, for which he places the first part of this work outside of any discussion since they are historical events and the Mathematics of History is not a philosophical interpretation or a special vision of history. Accordingly, once the mathematical law has been understood, dear reader, in the pages of historical text of your library, you can mark and refer to the curve corresponding to historical events and you will obtain the curve of the empire, of the individual liberty and the mathematical-sociological law of the country or countries you are interested in, said mark being left in your book to verify in this manner, objectively, that the mathematics of history is the Law of History and wherefore, its true concept.�
