ABSTRACT The Scottish judge and ‘eccentric’ philosopher James Burnett, Lord Monboddo’s (1714–1799) significance within Enlightenment thought is usually seen as stemming from his Origin and Progress of Language (6 vols., 1773–1792). The OPL was a major contribution to the Enlightenment’s debate over the philosophy of language, and established Monboddo’s reputation as an innovative and influential, yet controversial and credulous proto-anthropologist. In the following I explore Monboddo’s Egyptomania and the role it plays in his account of the origins and development of (...) religion within his larger ‘History of Man’. Monboddo’s idiosyncratic and untimely fusion of conjectural history, Buffon-inspired natural history, Christian theology, Platonic and Aristotelian philosophy and credulous interest in Egyptology, especially in Antient Metaphysics (6 vols., 1779–1799), make him extremely difficult to place within the Scottish Enlightenment. I want to bring Monboddo back into our conversation about the Scottish Enlightenment, shed light in the process on his highly idiosyncratic combination of enlightened and unenlightened thought and, using Monboddo’s example, emphasize some interesting if unexpected aspects of the Scottish Enlightenment’s application of the ‘science of human nature’ to the study of religion. For Monboddo, human civilization and religious knowledge owes their existence to Egyptian daemon-kings. (shrink)
