Ralph Cudworth ( ;; 1617 – 26 June 1688) was an English Anglican clergyman, Christian Hebraist, classicist, theologian and philosopher, and a leading figure among the Cambridge Platonists who became 11th Regius Professor of Hebrew (1645–88), 26th Master of Clare Hall (1645–54), and 14th Master of Christ's College (1654–88). A leading opponent of Hobbes's political and philosophical views, his magnum opus was his The True Intellectual System of the Universe (1678). Family background Ancestry Cudworth's family reputedly originated in Cudworth (near Barnsley), Yorkshire, moving to Lancashire with the marriage (1377) of John de Cudworth (died 1384) and Margery (died 1384), daughter of Richard de Oldham (living 1354), lord of the manor of Werneth, Oldham. The Cudworths of Werneth Hall, Oldham, were lords of the manor of Werneth/Oldham, until 1683. Ralph Cudworth (the philosopher)'s father, Ralph Cudworth (Snr), was the posthumous-born second son of Ralph Cudworth (d.1572) of Werneth Hall, Oldham. The Rev.

He then applied for the rectorate of Aller, Somerset (an Emmanuel College living) and, resigning his fellowship, was appointed to it in 1610.
