Kent's Writing History (1941) builds Chapter I's working vocabulary of historical criticism directly on Bernheim's named four-step schema

In the body text of Chapter I ("Why History," pp. 5-8), Sherman Kent does not merely footnote Ernst Bernheim — he adopts Bernheim's own four-step schema as the organizing structure for his opening discussion of historical criticism: "Ernst Bemheim was one of the first to make a systematic study of the systematic study of historical method. In his Manual of Historical Method and Philosophy of History,2 he described it in four steps: (1) Heuristik, the gathering of historical evidence; (2) Kritik, the evaluating of this evidence; (3) Auffassung, the moment of comprehending the true meaning of the evaluated evidence; (4) Darstellung, the presentation of the new idea in terms of the evaluated evidence." Kent then uses "Kritik" as a live working term across several more paragraphs and later locates his own discussion of historian's self-bias "in Bemheim's third stage of the historical process, the step which he calls Auffassung." His footnote identifies the exact edition: "Ernst Bernheim, Lehr- buch der historischen Methode und der Geschichtsphilosophie (6th rev. ed., Leipzig, 1908; 1st ed. 1889)."

This closes the mechanism gap observation-sherman-kent-historian-training-partial-lineage-into-cia-tradecraft left open: the "test authenticity, then curb bias" two-step that note found resembling Langlois and Seignobos's External/Internal Criticism split is not an independent convergence on Kent's part. Kent explicitly frames his own book's version of that two-step as direct exposition of Bernheim's named Kritik/Auffassung stages — one documented step removed from Langlois-Seignobos, who Kent's own bibliographical note says came nine years after Bernheim and resembled his structure.
