Israel's monomaniacal Spinoza worship is amusing and exasperating by turns. For a start, his insistence that Spinoza was the singular font of the Enlightenment leaves him without a story of the Enlightenment's intellectual or cultural origins. Every historian has to begin somewhere, but the fact that Israel begins with Spinoza, and then reduces most of what follows the philosopher to a footnote, leaves his account of the Enlightenment founded on something like immaculate conception.
