In his discussion of the factors in historical causation, Christopher Dawson identified four primary factors, “(1) race, i.e., the genetic factor; (2) environment, i.e., the geographic factor; (3) function or occupation, i.e., the economic factor,” and, finally, (4) “thought, or the psychological factor.” Each of these factors has received some special emphasis at some epoch in the history of thought on historical causation. It is Dawson’s unique contribution to the field of thought on historical causation, however, to highlight the psychological factor as the decisive factor in the movements of history, as the human factor which unites and, in a sense, governs and directs the others.
Race, or the genetic factor, is the factor of historical causation which has received the greatest emphasis in the modern era, though it is by no means unique to the modern era. Aristotle, for example, says of “the poets” that “they thought that the barbarian and the slave were by nature one.” It was in the modern era, however, that race came to be identified by certain thinkers as the most central aspect of historical causation. The most extreme forms of the position which places race as the central determinative factor in historical causation have largely collapsed under the weight of the atrocities these theories have led to. For example, Alexander H. Stephen’s theory of the natural servility of those of African descent became an ex post facto justification for the existence of race-based chattel slavery in the American South. The most infamous example is the theory, generally associated with the Nazis but adopted more widely by eugenicists of various political stripes near the turn of the 20th century, of a malignancy transmitted via the blood of particular ethnic groups, an idea which counts the Holocaust among its consequences. Although undue focus upon the genetic factor in historical causation has largely been discredited through its own horrendous consequences, this theory has returned with renewed vigor in unexpected places, as among those who argue that an innate predisposition toward certain sexual behaviors implies the necessity of social acceptance of said behaviors.
A panicked reaction against the consequences of the racialist theory of historical causation has led to a renewed emphasis upon the two other material factors, the geographic and the economic. The geographic factor undoubtedly has the longest pedigree of the two. In his History, for example, Herodotus, writing in the 5th century BC, linked the origins of Egyptian culture, including their language and religion, to the geography of the land they inhabited and its environment. One of the most popular of the modern reiterations of this ancient idea of geographic determinism is that of Jared Diamond in his Guns, Germs, and Steel. In his 1997 book and eponymous 2005 television documentary series, Diamond sets out to answer a question put to him by a native of New Guinea, though perhaps more succinctly articulated nearly a century prior by W. E. B. Du Bois in his The Souls of Black Folk, “Why has civilization flourished in Europe, and flickered, flamed, and died in Africa?” In the wake of the racialist ideologies of the 19th and early 20th centuries, Diamond merely frantically replaces one set of material factors (genes) with another (geography), arguing eloquently but not persuasively for an exclusion of the human factor from the central position.
The economic factor of historical causation is of a decidedly modern origin. Its origins are contemporaneous with the rise of race to prominence as the central factor in historical causation. Unlike race, however, the economic factor has maintained its popularity as a material explanation for historical causation to the present day. Its most well-known and vociferous exponent, Karl Marx, argued that “the life-process of society … is based on the process of material production.” Having fixed economics as the final definitive factor in historical causation, Marx proceeded to dismiss all other aspects of a society, including its religious and political systems, insisting that far from possessing any causative or explanatory power they themselves were merely the derivative products of the economic factor. Marx’s explanation of all history through economic factors proved convincing enough to win over a great many of the leading intellectuals of the 20th century, including W. E. B. Du Bois, who, fairly late in his life, attempted to answer his question through applying the Marxist theory of material dialectic to race relations in the modern world.
Like the racial and geographic theories, however, Marx’s theory of economic causation in history reduces history to the merely material. Positing race, geography, or economy as the central causative factor in history displaces human life and its unique features, rational thought and spiritual insight, from their due place of centrality. This reduction to the merely material is largely a modern phenomenon. Even among those ancient thinkers who identified material factors of causation, there was rarely an outright exclusion of the human factor. Plato, for example, in his Laws, placed what is perhaps an undue emphasis on the geographic factor in his contention that a city near a “sea, and well provided with harbours, and an importing rather than a producing country” requires “some mighty saviour … and lawgivers more than mortal, if … [it] were ever to have a chance of preserving … [itself] from degeneracy and discordance of manners.” Yet even in this statement of the great effect of the geographic factor upon a state, Plato evinces a belief in the human factor of a “mighty saviour” and “lawgivers more than mortal” as the most decisive factor in the shaping of a people’s history.
It is precisely such great men whom Christopher Dawson pointed to as the most important factor in historical causation, reminding the modern world that it is not so much man who is subject to the material factors of race, geography, and economy, as it is man who works within the confines of these factors to reshape them and create new and great cultures. “Behind every civilization there is a vision,” he writes in his Progress and Religion, “a vision which may be the unconscious fruit of ages of common thought and action, or which may have sprung from the sudden illumination of a great prophet or thinker.” Underlying historical causation, says Dawson, creating and giving impulse to material factors is the human factor. Behind every great movement in history one will not find, if followed to its roots, a gene, a mountain, or an exchange of goods. Instead, one will discover the human will.
