Clay Greene’s scholarly interests lie in the literary and intellectual culture of early modern England, especially from the 1650s through the 1750s. Within that broad framework, he studies the intersections of philosophy, theology, and poetry, with a focus on the poetic work of John Milton. His dissertation project covered the revival of the Platonic doctrine of the pre-existence of the soul among English poets and philosophers, arguing that this revival constituted a genuine religious movement of significance. He is fascinated by the ways that individual moral and spiritual considerations always take place against a complete background of metaphysical assumptions about the nature and significance of reality. No era better exemplifies this fact than the late seventeenth century, a time when the “world pictures” of entire societies were in radical flux. Recently, his interests have shifted from the metaphysical to the physical, with a special focus on the imagination of warfare in early modernity, but even here, the focus remains on how beliefs about war crucially depend upon general beliefs about man’s role in the cosmic drama of creation.
