Spinoza, then, emerged as the supreme philosophical bogeyman of Early Enlightenment Europe. Admittedly, historians have rarely emphasized this. It has been much more common, and still is, to claim that Spinoza was rarely understood and had very little influence, a typical example of an abiding historiographical refrain which appears to be totally untrue but nevertheless, since the nineteenth century, has exerted an enduring appeal for all manner of scholars. In fact, no one else during the century 1650–1750 remotely rivalled Spinoza's notoriety as the chief challenger of the fundamentals of revealed religion, received ideas, tradition, morality, and what was everywhere regarded, in absolutist and non-absolutist states alike, as divinely constituted political authority.
