From the time of the publication of Henry More's first work, the collection of poems, ΨγΧΩΔΙΑ Platonica , Platonism provided the dominant theme in his philosophy. At Cambridge, More, his colleague, Ralph Cudworth, and their disciples, were responsible for a considerable revival of English Platonism, which became an important factor in late seventeenth-century natural philosophy. This movement is noted for its active and influential opposition to the mechanical world view, characterized in the writings of Hobbes and Descartes.
