Not only are we taught to think of intellectual history as something largely produced by individuals writing great books or thinking great thoughts, but these ‘great thinkers’ are assumed to perform both these activities almost exclusively with reference to each other. As a result, even in cases where Enlightenment thinkers openly insisted they were getting their ideas from foreign sources (as the German philosopher Gottfried Wilhelm Leibniz did when he urged his compatriots to adopt Chinese models of statecraft), there’s a tendency for contemporary historians to insist they weren’t really serious; or else that when they said they were embracing Chinese, or Persian, or indigenous American ideas these weren’t really Chinese, Persian or indigenous American ideas at all but ones they themselves had made up and merely attributed to exotic Others.
