This essay argues that today's dominant understanding of secularization—as an epochal transition from a society based on religious belief to one based on autonomous human reason—first appeared in philosophical histories at the beginning of the nineteenth century and was then anachronistically applied to early modern Europe. Apart from the earlier and persisting canon-law use of the term to refer to a species of exclaustration, prior to 1800 the standard lexicographical meaning of “secularization” was determined by its use in public law and diplomacy to name the civil conversion of ecclesiastical property and jurisdiction. Prior to the same point the most important use of the adjective “secular” was in political jurisprudence as a synonym for temporal, civil, and political, to name a religious–political settlement from which rival theologies had been excluded as the condition of its negotiation. But this usage was domain-specific, was quite compatible with religious devotion, and had nothing to do with the putatively secular character of the spheres of philosophy or the natural sciences, thence “society”. Far from seeing a shift from religious belief to autonomous rationality, early modernity in fact witnessed a significant intensification of religious belief and practice under the impact of rival confessional movements. It also emerges that the nineteenth century was characterized not by the supersession of confessional religions—or their conversion into rational religion or moral philosophy—but by their remarkable persistence and adaptation to new circumstances. In light of this, the essay argues that the variant philosophical-historical conceptions of secularization—as the epochal supersession of religious belief by human rationality—should not be understood as theories of a putative process but as “combat concepts”. These were internal to an array of rival cultural-political factions that first emerged in early nineteenth-century Protestant Germany and that continue to do battle today.

4 This difference between the public-law (Säkularisation) and philosophical-historical (Säkularisierung) usages of “secularization” began to be marked in the 1930s and was clearly spelled out in the Geschichtliche Grundbegriffe, as was the identification of the early 1800s as the point of emergence of the philosophical-historical meaning.

13 “Secularization” does not appear in any of Spinoza's Latin texts; nor, it seems, does the adjective “secular”. Neither term is listed in Emilia Boscherini's authoritative Lexicon Spinozanum (The Hague, 1970). “Secular” does not appear in the Latin text of the Tractatus Theologico-Philosophicus, and seems to be an interpolation introduced by Robert Elwes's English translation in the context of 1880s rationalism. Elwes translates Spinoza's jus principatus—the right of rule/imperium—with the phrase “the rights of secular rulers”. See and compare de Spinoza, Benedict, Tractatus Theologico-Politicus, vol. 3 of Benedict de Spinoza: Opera (Hamburg, 1670), 223Google Scholar; and Spinoza, , A Theologico-political Treatise and A Political Treatise, trans.

30 It might well be the case that seventeenth-century natural philosophers did not in fact characterize their sciences as “secular”, since they did not confront the historical problem—the need to establish non-theological political settlements to religious conflicts—that had led to the use of the term by political jurists.
