Henry Adams 75Henry Adams
(1838-1918)
Collected works: 12+

Adams Rule of Phase[RGM:811|1,310+] (SN:2) (CR:241)Spent over five decades attempting to explain history according to physical principals, physico-chemical principles generally; in his 9-volume History of United States America (1891), covering the years during the Jefferson administration (1801-1817), was penned with the sole intention to demonstrate causality in the course of human history, or as Adams would latter summarize “to satisfy himself whether, by severest process of stating, with the least possible comment, such facts as seemed sure, in such order as seemed rigorously consequent, he could fix for a familiar moment a necessary sequence of human movement”; his The Tendency of History (1896), attempted to describe history according to the second law of thermodynamics, albeit of the form of William Thomson's 1852 paper "On a Universal Tendency to the Dissipation of Mechanical Energy"; his The Rule of Phase Applied to History (1909) was reviewed by physicist Henry Bumstead, one of the few and only students of Willard Gibbs, the inventor of the phase rule; his A Letter to American Teachers of History (1910) gave sound advice for future generations of historians to start looking back at history scientifically, the way scientists look at reaction patterns between molecules, to view people as human molecules, and historical progress as governed by the laws of thermodynamics, just as is the historical progress of the universe.

Parallelogram of Social Forces Model(Library:21,000) (CR:34) English social physics themed historian;

Oswald Spengler 75Oswald Spengler
(1880-1936)
IQ EM=170 (RGM:245|1,500+) (CR:15) was a German philosopher of history;

“Today we live so cowed under the bombardment of this intellectual artillery that hardly anyone can attain to the inward detachment that is required for a clear view of the monstrous drama. The will-to-power operating under a pure democratic disguise has finished off its masterpiece so well that the object's sense of freedom is actually flattered by the most thorough-going enslavement that has ever existed.”
— Ostwald Spengler (1923), The Decline of the West, Volume Two (pg. 461)

His two-volume The Decline of the West (1922), wherein he outlines a Goethean-Nietzschean view of rise and falls of civilization, intermixed, supposedly, with entropy discussion.

Bede 75Bede
(672-735)

Thucydides 75Thucydides
(460-395BC)

(Cattell 1000:72) [RGM:175|1,500+] (FA:14) (CR:3) Greek historian and general;

“Modern criticism rightly regards Thucydides as the model of the rational and objective historian who made it his first duty to leave the finger of god out of history and to tidy up the mundane events of the human drama. The contrast between his work with respect to the gods and the histories of his predecessor Herodotus and his successor Xenophon is plain; it is a contrast so great, in fact, as to provoke the observation from some (e.g. K. J. Dover) that Thucydides may well have been an atheist.”
— Borimir Jordan (1986), “Religion in Thucydides”

noted for his participation in and later secular recounting of the Peloponnesian War (431-404BC), wherein the Athenians battled the Spartans; considered, by some (Ѻ), to be the father of “scientific history”, i.e. history based on evidence-gathering and analysis of cause and effect.
