Secondary Sources

F. Amerini, “Utrum inhaerentia sit de essentia accidentis. Francis of Marchia and the debate on the Nature of Accidents.”
Vivarium 44 (2006) 97–150.

Describes the interpretative problems presented by Aristotle's teachings on accidents. Amerini distinguishes three schools, the first of which reduces accidents entirely to modes of substance. Notes that Rufus holds (SMet 7.1.Q3–6) that accidents have no nature apart from substance. In fact, Rufus claims further that accidents are unintelligible apart from substance, since we cannot understand them without also understanding substances. Accidents are not entities but modes of being, not true modes of being, but only logical modes. So Rufus seems to be a reductionist, a position held by few according to Amerini.

Announces the discovery of a new manuscript of In Aristot. De anima, Florence, BN Conv. soppr. G.iv.853 (F853) by J. De Raedemaeker. Remarks that there are marginal notes attributing it to “Magister Alesander” and to “Alexander Magnus.” Suggests that its attribution to Alexander or to Richard Rufus will be a capitivating question. Remarks that Gauthier did not deny the claim that it was the earliest surviving De anima commentary, only held that Alonso's arguments for the claim were not decisive. Holds mistakenly that collation of F853 and Erfurt, UB, Dep. Erf., CA Q.312 (Q312) shows that Q312 depends on F853 and not vice versa.

DeWitt, R. & Long, J., "Richard Rufus's reformulations of Anselm's Proslogion argument." International Philosophical Quarterly 47 (2007), 329-347.

Rufus "subjects Anselm's argument for God's existence in his Proslogion to the most trenchant criticism since Gaunilon wrote his response on behalf of the `fool'. Anselm's argument is subtle but sophistical, claims Rufus, because he fails to distinguish between signification and supposition."

Donati, S., “The Anonymous on the Physics in Erfurt.”
Recherches de théologie et philosophie médiévales 72 (2005) 232–362.

Views the Sententiae Oxonienses, Scriptum in Metaphysicam Aristotelis (SMet), and the Memoriale in Metaphysicam Aristotelis as certainly by Rufus, but raises doubts about the attribution of In Aristot. Physicam and In Aristot. De anima. Claims that if Rufus wrote both SMet and those works, his lack of consistency would suggest that he was not an insightful thinker. Correctly notes that the marginal citation of Richard in Marchia codex Chigi B.vii.13 is not in the original hand. Claims that it refers to article 2 as a whole on celestial motion, contrary to Wood who refers it only to the last paragraph of article 2, which describes a form that is strictly speaking neither successive nor permanent. See also Schabel, who refers the citation to article 3.

Dowden, B., "The Infinite,"
The Internet Encyclopedia, ISSN 2161-0002, 6 November 2016.

"Aristotle said the past is infinite because, for any past time we can imagine an earlier one. It is difficult to make sense of his belief ... After all, the past has an end, namely the present, so its infinity has been completed and therefore is not a potential infinity. This problem with Aristotle’s reasoning was first raised in the 13th century by Richard Rufus of Cornwall. It was not given the attention it deserved because of the assumption for so many centuries that Aristotle couldn’t have been wrong about time."

Ebbesen, S., “Roger Bacon and the Fools of His Times.”
Cahiers de l'Institut du Moyen Âge Grec et Latin 3 (1970) 40–44.

Raises problems for the attribution of the Abstractiones to Richard Rufus, since the doctrine Bacon criticizes was espoused by many.

Gál, G., “Commentarius in Metaphysicam Aristotelis cod. Vat. lat. 4538, fons doctrinae Richardi Rufi.”
Archivum franciscanum historicum 43 (1950) 209–242.

Auguste Pelzer discovered Rufus' Metaphysics commentary and convinced V. Doucet of its authenticity. Doucet turned over the task of researching the attribution to Gál. Gál concluded – prematurely, as he later decided – that it was not a work by Rufus. Rufus' references as a Franciscan theologian to himself as a secular author misled Gál. The article provides a guide to an enormous commentary. It lists the titles of the questions and publishes excerpts.

__, “Opiniones Richardi Rufi Cornubiensis a censore reprobatae.”
Franciscan Studies 35 (1975) 136–193.

Correctly attributes the Metaphysics commentary to Rufus and documents his influence on Scotus. Prints substantial excerpts from the Paris theology lectures as well marginal notes censuring Rufus. Notes Rufus' anticipation of Ockham's views on relations.

__, “Viae ad exsistentiam Dei probandam in doctrina Richardi Rufi.”
Franziskanische Studien 38 (1956) 177–202.

Publishes substantial excerpts from Rufus' Oxford theology lectures and brief excerpts from Assisi 138. Shows that Rufus anticipated both Thomas' criticism of Anselm's Proslogion proof for God's existence and Scotus' modal proof for the existence of God.

Gauthier, R., “Le traité De anima et de potenciis eius.”
Revue des science philosophiques et théologiques 66 (1982) 3–55.

Here Gauthier began the process of revising our assumptions about Parisian Aristotelianism. The treatise he included cites Aristotle and Averroes in the year 1225, considerably earlier than was once believed possible.

Harkins, Franklin. "The Embodiment of Angels: A Debate in Mid-Thirteenth-Century Theology," Recherches de Théologie et Philosophie Médiévales 78 (2011) 25-58.

Notes that Rufus offers arguments both for and against the claim that angels have bodies, but does not settle the issue. Cites the following simple argument for the claim (SOx 2.8B): The devil cannot suffer from corporeal fire unless he has a body; but the devil does suffer, and the fire of hell is corporeal as Augustine says in the City of God; therefore the devil has a body.

Notes that Bonaventure annotated Assisi, Sacro convento 138, a collection of questions by Robert Grosseteste, Adam Marsh, Richard Rufus, and a number of Parisian masters on subjects treated in Lombard's Sentences. Henquinet thinks it was probably transcribed for Bonaventure's use.

Describes Albert's use of Rufus' account of universals: “ Albert composed the chapter of his Metaphysica which deals with the question of how a quiddity relates to the individuals of which it is the quiddity by borrowing entire sections from the chapter of Rufus's Scriptum in Metaphysicam Aristotelis where Rufus deals with the same question. In so doing, however, he ... seriously alters the sense of the original.”

__, “Richard Rufus on Naming Substances.”

Describes the development of Rufus' metaphysical views from the painstaking reconstruction of Aristotelian naming theory found in MMet to “a striking example of ‘Christian Aristotelianism’.”

__, “Richard Rufus's Account of Substantial Transmutation.”
Medioevo 27 (2002) 168–191.

Describes Rufus' theory of substantial transformation based on a metaphysics which posits incomplete beings,which reconciles Augustine with Aristotle. The view was adopted by Bonaventure, Albert the Great, and Roger Marston, but criticized by Aquinas, Henry of Ghent, and John Duns Scotus.

Noone, T., An Edition and Study of the Scriptum super Metaphysicam, bk. 12, dist. 2: A Work Attributed to Richard Rufus of Cornwall.
Ph.D. dissertation, University of Toronto, 1987.

Correctly attributes the Metaphysics to Rufus, citing Leonard Boyle. Conducts a sustained argument against Raedts who disputed the attribution. Publishes substantial portions of the commentary on Lambda. Incorrectly raises doubts about the authenticity of the Oxford theology lectures preserved in Balliol 62. Assuming that that work is inauthentic, Noone speculates on the time and place the Scriptum was written. Opts for Oxford in the 1240s. So far only Noone has expressed reservations about the authenticity of the Oxford lectures.

Normore, C., “The Matter of Thought.”
In Representation and Objects of Thought in Medieval Philosophy, ed. H. Lagerlund, Aldershot 2007, pp. 117–133.

Normore traces modern disputes about the nature of thought (think Chisholm vs. Sellars)... to a disagreement about how to interpret Aristotle’s claim that in order to know “the mind must be pure from all admixture, since the co-presence of what is alien to its nature is a hindrance … so it can have no nature of its own” (De anima 3.4.429a19-21). Since Aristotelians assume that understanding or thought requires that the mind take on the form it thinks, the question is what purity requires. ...Does the absence of interfering admixture means that mind cannot understand itself, since it cannot take on a form it already has? Or does it mean that the mind cannot understand anything incompatible with itself, since it cannot take on contrary forms? Aquinas embraced the second alternative ...and agreed with Averroes that since the mind is immaterial, it cannot understand material forms, so the objects of our thoughts must be dematerialized like our immaterial souls. By contrast Richard Rufus rejected the dilemma... and posited thought objects that are not material but also not immaterial in the sense that angels or the soul are spiritual. Rather objects of thought are ideas or species that are spiritual insofar as they are forms abstracted from corporeality and position. Because these ideas are unsituated and their subjects unextended, the mind can simultaneously understand objects that cannot coexist outside the mind. Because these ideas don’t share the ontological status of the soul, the mind can take them on, and the mind can understand itself by understanding its own idea or species.

Rufus, and Bonaventure following Rufus, reject the distinction between God's absolute and ordained power on the grounds that acting inordinately is not a power, just as being able to sin is not a power. Discussion based on excerpts quoted by G. Gál.

Schabel, “Francis of Marchia's Virtus derelicta and the Context of Its Development.”
Vivarium 44 (2006) 60–80.

Rejects the claim that the marginal citation of Bonaventure and Richard in Chigi B.vii.13 refers to Richard Rufus. Holds that it refers to Richard Middleton instead and a discussion of sacramental efficacy. Expresses concern about taking “away from Marchia his most famous idea.” Holds that the attribution of In Physicam Aristotelis to Rufus “must be stronger if we are to rewrite th history of the reception of Aristotle's Physics in the West.”

Synan, E., “The ‘Introitus ad sententias’ of Roger Nottingham, O. F. M..”
