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 (1645–1688), 26th Master of Clare Hall (1645–1654), and 14th Master of Christ's College (1654–1688). A leading opponent of Hobbes's political and philosophical views, his magnum opus was his The True Intellectual System of the Universe (1678).
Cudworth's family reputedly originated in Cudworth (near Barnsley), Yorkshire, moving to Lancashire with the marriage (c.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 philosopher's father, Ralph Cudworth (1572/73–1624), was educated at Emmanuel College, Cambridge, where he graduated with a BA in 1592/93 and an MA in 1596. Emmanuel College (founded by Sir Walter Mildmay (1584), and under the direction of its first Master, Laurence Chaderton) was, from its inception, a stronghold of Reformist, Puritan and Calvinist teaching, which shaped the development of Puritan ministry, and contributed largely to the emigrant ministry in America. Ordained in 1599 and elected to a college fellowship by 1600, Cudworth Snr was much influenced by William Perkins, whom he succeeded, in 1602, as Lecturer of the Parish Church of St Andrew the Great, Cambridge. He was awarded the degree of Bachelor of Divinity in 1603. He edited Perkins's Commentary on St Paul's Epistle to the Galatians (1604), with a dedication to Robert, 3rd Lord Rich (later 1st Earl of Warwick), adding a commentary of his own with dedication to Sir Bassingbourn Gawdy. Lord Rich presented him to the Vicariate of Coggeshall, Essex (1606) to replace the deprived minister Thomas Stoughton, but he resigned this position (March 1608), and was licensed to preach from the pulpit by the Chancellor and Scholars of the University of Cambridge (November 1609). He then applied for the rectorate of Aller, Somerset (an Emmanuel College living) and, resigning his fellowship, was appointed to it in 1610.
His marriage (1611) to Mary Machell, (who had been "nutrix" – wet nurse, or preceptor – to Henry Frederick, Prince of Wales) brought important connections. Cudworth Snr was appointed as one of James I's chaplains. Mary's mother (or aunt) was the sister of Sir Edward Lewknor, a central figure (with the Jermyn and Heigham families) among the Puritan East Anglian gentry, whose children had attended Emmanuel College. Mary's Lewknor and Machell connections with the Rich family included her first cousins Sir Nathaniel Rich and his sister Dame Margaret Wroth, wife of Sir Thomas Wroth of Petherton Park near Bridgwater, Somerset, influential promoters of colonial enterprise (and later of nonconformist emigration) in New England. Aller was immediately within their sphere.
The children of Ralph Cudworth Snr and Mary (née Machell) Cudworth were:
General James Cudworth (1612–82) was Assistant Governor (1756–1758, 1674–1680) and Deputy Governor (1681–82) of Plymouth Colony, Massachusetts, and four-times Commissioner of the United Colonies (1657–1681), whose descendants form an extensive family of American Cudworths.
Elizabeth Cudworth (1615–1654) married (1636) Josias Beacham of Broughton, Northamptonshire (Rector of Seaton, Rutland (1627–1676)), by whom she had several children. Beacham was ejected from his living by the Puritans (1653), but reinstated (by 1662).
John Cudworth (1622–1675) of London and Bentley, Suffolk, Alderman of London, and Master of the Worshipful Company of Girdlers (1667–68). On his death, John left four orphans of whom both Thomas Cudworth (1661–1726) and Benjamin Cudworth (1670–15 Sept. 1725) attended Christ's College, Cambridge. Benjamin Cudworth's black memorial slab is in St. Margaret's parish church, Southolt, Suffolk.
Jane/Joan(?) Cudworth (born c.1624; fl. unmarried, 1647) may have been Ralph's sister.
The second son, and third of five (probably six) children, Ralph Cudworth (Jnr) was born at Aller, Somerset, where he was baptised (13 July 1617). Following the death of his father, Ralph Cudworth Snr (1624), John Stoughton (1593–1639), (son of Thomas Stoughton of Coggeshall; also a Fellow of Emmanuel College), succeeded as Rector of Aller, and married the widow Mary (née Machell) Cudworth. Dr Stoughton paid careful attention to his stepchildren's education, which Ralph later described as a "diet of Calvinism". Letters, to Stoughton, by both brothers James and Ralph Cudworth make this plain; and, when Ralph matriculated at Emmanuel College, Cambridge (1632), Stoughton thought him "as wel grounded in Scho[o]l-Learning as any Boy of his Age that went to the University". Stoughton was appointed Curate and Preacher at St Mary Aldermanbury, London (1632), and the family left Aller. Ralph's elder brother, James Cudworth, married and emigrated to Scituate, Plymouth Colony, New England (1634). Mary Machell Cudworth Stoughton died during summer 1634, and Dr Stoughton married a daughter of John Browne of Frampton and Dorchester.
Pensioner, Student and Fellow of Emmanuel College (1630–1645)
From a family background embedded in the early nonconformity and a diligent student, Cudworth was admitted (as a pensioner) to his father's old college, Emmanuel College, Cambridge (1630), matriculated (1632), and graduated (BA (1635/36); MA (1639)). After some misgivings (which he confided in his stepfather), he was elected a Fellow of Emmanuel (1639), and became a successful tutor, delivering the Rede Lecture (1641). He published a tract entitled The Union of Christ and the Church, in a Shadow (1642), and another, A Discourse concerning the True Notion of the Lord's Supper (1642), in which his readings of Karaite manuscripts (stimulated by meetings with Johann Stephan Rittangel) were influential.
11th Regius Professor of Hebrew (1645) and 26th Master of Clare Hall (1645–1654)
Following sustained correspondence with John Selden (to whom he supplied Karaite literature), he was elected (aged 28) as 11th Regius Professor of Hebrew (1645). In 1645, Thomas Paske had been ejected as Master of Clare Hall for his Anglican allegiances, and Cudworth (despite his immaturity) was selected as his successor, as 26th Master (but not admitted until 1650). Similarly, his fellow-theologian Benjamin Whichcote was installed as 19th Provost of King's College. Cudworth attained the degree of Bachelor of Divinity (1646), and preached a sermon before the House of Commons of England (on 1 John 2, 3–4), which was later published with a Letter of Dedication to the House (1647). Despite these distinctions and his presentation, by Emmanuel College, to the rectorate of North Cadbury, Somerset (3 October 1650), he remained comparatively impoverished. He was awarded the degree of Doctor of Divinity (1651), and, in January 1651/2, his friend Dr John Worthington wrote of him, "If through want of maintenance he should be forced to leave Cambridge, for which place he is so eminently accomplished with what is noble and Exemplarily Academical, it would be an ill omen."
Marriage (1654) and 14th Master of Christ's College (1654–1688)
Despite his worsening sight, Cudworth was elected (29 October 1654) and admitted (2 November 1654), as 14th Master of Christ's College. His appointment coincided with his marriage to Damaris (died 1695), daughter (by his first wife, Damaris) of Matthew Cradock (died 1641), first Governor of the Massachusetts Bay Company. Hence Worthington commented "After many tossings Dr Cudworth is through God's good Providence returned to Cambridge and settled in Christ's College, and by his marriage more settled and fixed."
In his will (1641), Matthew Cradock had divided his estate beside the Mystic River at Medford, Massachusetts (which he had never visited, and was managed on his behalf) into two moieties: one was bequeathed to his daughter Damaris Cradock (died 1695), (later wife of Ralph Cudworth Jnr); and one was to be enjoyed by his widow Rebecca (during her lifetime), and afterwards to be inherited by his brother, Samuel Cradock (1583–1653), and his heirs male. Samuel Cradock's son, Samuel Cradock Jnr (1621–1706), was admitted to Emmanuel (1637), graduated (BA (1640–1); MA (1644); BD (1651)), was later a Fellow (1645–56), and pupil of Benjamin Whichcote's. After part of the Medford estate was rented to Edward Collins (1642), it was placed in the hands of an attorney; the widow Rebecca Cradock (whose second and third husbands were Richard Glover and Benjamin Whichcote, respectively), petitioned the General Court of Massachusetts, and the legatees later sold the estate to Collins (1652).
