Can history be quantified?

Can the history of culture be quantified? I believe many historians would answer this question in the negative. The prevailing view seems to be that historical events are unique and unrepeatable, and any attempt to discover laws or recurring patterns in these phenomena is usually met with extreme suspicion. Let us remember as an example the antagonistic reaction provoked by works such as The Decline of the West by the German philosopher and historian Oswald Spengler, or A Study of History by the British historian Arnold Joseph Toynbee, whose conclusions, however, were based on qualitative analysis. It is not surprising, therefore, that to find true quantifiers of history, one must turn to authors who were not professional historians.

The first important attempt at a quantitative analysis of historical phenomena was undertaken by the Russian-born, American sociologist Pitirim A. Sorokin. In his monumental work, Social and Cultural Dynamics, he conducted a quantitative study of the history of Greco-Roman and Western thought, to analyze the evolution of thought patterns over the centuries and so discovering if there are discernible uniformities, and answering the following questions: Is there a systematic increase in historical development, as Marx, Comte, and other authors assert? Or, on the contrary, are there cyclical alternations? Can patterns of succession be detected between traditionally opposing philosophical schools: idealism and materialism; realism and nominalism; determinism and indeterminism? But Sorokin's study is incomplete, since it analyzes only two activities, philosophy and science, and does not distinguish between them (everyone is simply a thinker).

The second attempt at quantifying culture is due to A.L. Kroeber, an American anthropologist who tried to demonstrate in his book Configurations of the Growth of Cultures that geniuses are never born alone. Kroeber believed that cultural movements are not arbitrarily distributed over time, because those who implement them influence one another through imitation or emulation, creating a cultural environment and forming configurations or groupings of individuals born around the same time and cultivating the same cultural activity. In support of this thesis, Kroeber analyzed several thousand historical names from Egyptian, Mesopotamian, Indian, Chinese, Japanese, Mesoamerican, Islamic, Hebrew, Greek, Roman, Byzantine, and Western civilizations. The cultural fields considered were philosophy, science, philology, literature and drama, painting, sculpture, and music. However, Kroeber's analysis is not fully quantitative. He classifies the authors under study into three categories: cultural pinnacles (marked with two asterisks); important authors (one asterisk); and the rest (without asterisks).

I have just published a book where I address in detail the quantification of history. Its title is The Quantification of History and the Future of the Western World. I wrote the first version a long time ago, in 1985. In 1996, I used my studies for the field of science in the introduction to my dictionary, 1.000 grandes científicos (1,000 Great Scientists, Editorial Espasa). In 2014, I expanded and updated the book, because a publisher was willing to publish it, although at the last minute they canceled the contract, claiming that my ideas were not the same as theirs (I suppose because I am against abortion). I talked about this in another post. Now, almost 12 years later, I have published it on Amazon, in Spanish and in English translation.

The studies in the book cover almost three thousand years of the history of Greco-Roman and Western civilization in five fields of activity: science, philosophy, literature, visual arts, and music. This is a biographical analysis, in which each field is represented by its practitioners, whose birth, peak, and death dates (if known) are noted, as well as their nationality.

Each historical figure has received a quantitative rating represented by a number between zero and ten (eight for scientists), calculated from the number of lines dedicated to each author in the texts or encyclopedias that served as the basis for this study. The criteria varied depending on the specific field of activity, as well as the sources of information used. Given that encyclopedias mention a huge number of individuals, which grows exponentially as the rating decreases (there are far fewer excellent creators than good ones, and far fewer good ones than average ones), I subjected the results to a screening process, eliminating those that fall below a certain threshold, which depends on the field of activity. In the case of the Western civilization, the same data have sometimes been subjected to several different thresholds to normalize them and facilitate comparison with Greco-Roman civilization.

The next step was to divide three thousand years of history into intervals of reasonable length. Here I considered using the century, the half-century, or the quarter-century. I have used little the quarter-century as being too short, because a person's creative period often exceeds this duration, making it difficult to assign to each individual a single quarter-century. Therefore, in general I used the century and the half-century, depending on the amount of data available.

Although I am not a historian, this is not the first time I have ventured into the field of history in my popular science books. In 1979, my book Human Cultures and Evolution (Vantage Press, New York) was published, and in 2017, Evolución biológica y evolución cultural en la historia de la vida y del hombre (Biological Evolution and Cultural Evolution in the History of Life and Man, CEU Ediciones, Madrid). Since my two great predecessors were not historians and have set a precedent, I consider myself justified to enter this field. 

In the two next posts I’ll give a few samples of the results of my analysis.
