Abstract

The purpose of this book is to give a complete scientific notion of generation, and its implications for virtually all historical and philosophical disciplines. Generation, as a biological notion, is as old as mankind, but as a scientific notion, it is as recent as in the nineteenth century. The authors of that century, however, who have something to say about the matter—and Marias studies all of them—are incomplete, superficial, and even mistaken. The philosopher who developed a complete and definitive theory of generations was José Ortega y Gasset, who derives it from his philosophy of radical reality or human life considered both individually and collectively. Briefly and very incompletely, a generation can be defined as constituted by those who are not only contemporary but also coetaneous, i.e., who have the same beliefs, problems and ideas and consequently contribute to the formation of the world in an equal or similar fashion; a generation lasts fifteen years, and in a given period of time there coexist three generations, the young, the mature, and the old. A chapter follows about the vicissitudes of the generations theme in our century, and again, in spite of Ortega’s comprehensive analysis, the authors who deal with the theme are found wanting. Finally the problems involved in the theory of generations, particularly the question concerning the empirical existence of generations and the way of determining their succession, are discussed and an attempt is made to solve them. Prescinding from whether Marias’ treatment of the concept of generations could well inaugurate a new movement in contemporary philosophy, his work will serve as a useful corrective to the many superficial treatments of the ‘generation gap’ that have been published.—F.
