From the time of the publication of Henry More's first work, the collection of poems, ΨγΧΩΔΙΑ Platonica (1642), 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.
