The Origin and Goal of History
Jaspers, Karl. The Origin and Goal of History. Translated by Michael Bullock. New Haven, CT: Yale University Press, 1953.
Why this matters here
Karl Jaspers's comparative history introduced the Axial Age framing used at this chapter's opening. Before Certainty Arrives cites the book specifically for that intellectual origin, while distinguishing later questions about whether the category describes a single common historical transformation.
