The English Dominican friar and theologian Richard Knapwell (Clapwell) (fl. 1284–1286) is best known as an early defender of Thomas Aquinas. He was the first to respond to William de la Mare’s Correctorium fratris Thomae (Correction of Brother Thomas), a Franciscan attack consisting of 117 articles identifying purported errors drawn from several of Aquinas’s major writings. Knapwell’s detailed riposte, composed in the early 1280s, was the earliest and most extensive of a series of polemical Correctoria corruptorii fratris Thomae (Corrections of the Corruptor of Brother Thomas) that would appear, and Knapwell’s contribution is known as the Correctorium “Quare.” Knapwell’s commitment to Aquinas’s writings, however, was not fully evident in his earlier work, as Knapwell had lectured on the Sententiae of Peter Lombard at Oxford sometime between 1269 and 1277, and his surviving notes or Notabilia exhibit an admixture of views taken from Aquinas and Augustine. After writing the Correctorium “Quare,” Knapwell incepted as a master in theology at Oxford in 1284–1285, and not long afterward he produced the De unitate formae (On the unity of form), a disputed question that brought about his condemnation. In that work, Knapwell asserted the theological neutrality of the Aristotelian metaphysical thesis that there is a single substantial form in human beings. The unity of form thesis was opposed by those who posited a plurality of forms, believing that the unity of form thesis was incompatible with a host of theological issues such as whether Christ’s body in the tomb was numerically identical with the body of the living Christ. In October 1284 the Franciscan archbishop of Canterbury John Pecham had renewed the prohibitions of 1277 concerning the unity of form thesis previously set by his Dominican predecessor, Robert Kilwardby. On the basis of Knapwell’s defense of the unity of form in De unitate formae, Pecham excommunicated Knapwell in April 1286. Knapwell traveled to Rome to argue his case before the pope, but the newly elected Franciscan pontiff Nicholas IV responded by silencing him in 1288. Nothing definite is known about his later activities. The extant works of Knapwell (beyond the abovementioned Notabilia, Correctorium “Quare,” and De unitate formae) include six additional disputed questions that pertain mostly to issues of human and divine cognition, and one short Quodlibet of twenty-nine questions on a variety of topics.
