Historians of philosophy have often discussed Aquinas's view of human knowledge as it appears in the first part of the Summa theologiae. They have observed that he represents a more philosophical view than the Augustinian account of divine illumination. Yet little attention has been paid to the relation between this discussion of human knowledge and the account of Christ's knowledge in the third part of the Summa theologiae. One reason for this neglect is that scholarship is often practiced within the spheres of intellectual inquiry that were framed during the modern period. We ignore issues present in primary texts in order to construct proof texts that respond to present-day philosophical interests. In pursuit of questions having to do with epistemology, logic, metaphysics, and ethics, rarely do historians or philosophers attempt to unravel the historical and theological context of specific texts. In regard to human knowledge, rarely do we read beyond questions 84 through 86 on the human knowledge of material objects, and even more rarely do we consider what Aquinas has to say about the knowledge of Christ. Rather, we treat questions on the human knowledge of material things as if they concerned issues raised today in epistemology or philosophy of mind.

Written from the perspective of theology as presented in the twentieth century, little attention is paid in these texts to Aquinas's classic account of human knowledge.Google Scholar

Interestingly enough, Pasnau widens his scope in his most recent book by also treating questions 87 and 88 on the human knowledge of self and of God, but he does not recognize that this is Aquinas's longstanding framework for considering human cognition and that Aquinas has theological reasons for doing so.

16 In a general account of the polemics between the Cathars and their opponents, Gedaliahu Stroumsa concludes that Aquinas does not seem to offer a serious response to the position of the Cathars. Aquinas did not write a specific treatise against the Cathars, but that is no reason to think that he did not respond. I argue below that he provides such a response in his treatment of knowledge and the Incarnation in the Summa theologiae. See Stroumsa, Gedaliahu G., “Anti-Cathar Polemics and the Liber De Duobus Principiis.” in Lewis, Bernard and Niewöhner, Friedrich, eds., Religionsgespräche im Mittelalter (Wiesbaden, 1992), 183. For an interpretation of Aquinas as often opposing the dualism of Averroes and Avicenna in the face of the Cathars, see Poupin, Roland, La papauté, les cathares & Thomas d'Aquin (Portet-sur-Garonne, 2000). Poupin adopts an ahistorical approach in that he does not read Aquinas from within the context of Dominican controversial works.Google Scholar

31 ST 3.9.4; 3.12.2. The three questions that follow Aquinas's initial consideration of Christ's knowledge repeat the structure of this inquiry: beatific knowledge in question 10, infused knowledge in question 11, and acquired knowledge in question 12. Considering the epistemological attention often given to Aquinas's discussions of human knowledge, we might expect Aquinas to say that he will use Aristotle in order to offer a more philosophical approach to the human knowledge of Christ. Yet, as I explain, he has other concerns in the text. On this dating, see Torrell, Jean-Pierre, Saint Thomas Aquinas, vol. 1: The Person and His Work , trans. Royal, Robert (Washington, 1996), 333.

33 ST 3.5.1. While Aquinas does not mention the Cathars at this point in his text, his frequent statements that the Manichees believed that Christ's body was only imaginary leave no doubt whom he has in mind. For examples that occur in the third part alone, see ST 3.5.2, 3.14.1, and 3.37.1. For a well-focused discussion of this point, see SCG 4.29. Edition used: Summa contra Gentiles (Rome, 1934). This view is often noted in Dominican works of the thirteenth century. For example, Hugh of St. Cher notes it in the third book of his commentary on the Sentences (3.2.22). For discussions by Hugh of this point and an edition of the text, see Principe, Walter, Hugh of Saint-Cher's Theology of the Hypostatic Union (Toronto, 1970), 54 and 167, respectively.Google Scholar
34 Where the Cathars are an issue, this is no idle concern. Moneta devotes a section to the claim that Christ truly suffered and died in order to bring out the corruptibility of his human nature while on earth (SACV 256–57). Key to human salvation, Christ not only assumed a body, but underwent suffering and death. Similar concerns motivate Aquinas's discussion of Christ's suffering and death in questions 46 through 50. For example, the reasons given for why Christ should not die sound like those of the Cathars (ST 3.50.1 obj. 1–3).Google Scholar
35 When considering whether Christ should have received the matter of his body from a woman, Aquinas includes a quotation from Augustine's letter to Volusianus (letter 137) that indicates how his view of human knowledge opposes that of the Cathars. He quotes Augustine claiming against the Manichees that the senses allow human beings to form concepts from material bodies (ST 3.31.4 ad 2).Google Scholar
36 For example, see the eighth argument and reply in the summa attributed to Alexander of Hales, Summa theologica 3.1.1.3.2.2 (Quaracchi, 4:165, 167) and Bonaventure's In Sent. 3.14.3.2 obj. 3 and ad 3.

37 Aquinas uses the name Cathari only once. He does this in one of his very few spirited works, Contra impugnantes Dei cultum et religionem (2.5), which appeared in 1256. In this work, Aquinas contrasts the Dominican religious life with the extreme position on poverty taken by the Cathar Desiderius. Moneta of Cremona points out that Desiderius describes Christ at times as having a spiritual and not a material body (SACV 248). Interestingly enough, according to Anselm of Alessandria, a Dominican inquisitor writing in 1266, Desiderius broke with his Cathar bishop in holding that Christ had a body and ate physical food.

55 As is made clear in the opening chapters of the section of his work titled De universo (1.1.2–12 [ed. Hotot, 1:594–607]). Of course, William does not only have the Cathars in mind. He criticizes many points of Aristotle and a number of Islamic philosophers. But, often when he criticizes these people, his criticisms also respond to the Cathars.

56 De universo 1.2.13 (ed. Hotot, , 1:702). This point is discussed in Heinzmann, “Zur Anthropologie,” 30.Google Scholar
57 Richard Heinzmann is careful to point out that William's early interpreters were wrong to assume that such philosophical theses represent a systematic view upon which William's theology hangs. Depending on the apologetical issue at hand, William uses philosophical points to obtain a conclusion, but does not construct a philosophically coherent methodology. Therefore, we should be cautious about pressing what appear to be contradictions. Another important point is that philosophers often take single statements out of context without reading related texts. In this case other texts on the immortality of the soul and the resurrection establish that William does not view human beings as essentially souls (Heinzmann, “Zur Anthropologie,” 27–28, 32–33). On the importance of viewing specific points within the context of the Magisterium divinale as a whole, see Kramp, J., “Des Wilhelm von Auvergne Magisterium divinale,” Gregorianum 1 (1920): 538–84; 2 (1921): 42–78, 174–87.Google Scholar
58 Avicenna influenced Aquinas on the view that matter is an important aspect of the human species. On this account it is incorrect to talk about the human essence without taking into account the human body. Avicenna grants a more important role to both matter and the human body than does Averroes, who identifies the human essence as form without matter. My point is that in this case, Avicenna's view is more useful against the Cathars than that of Averroes. For a clear account of the difference between Avicenna and Averroes on this matter in relation to Aquinas, see Maurer, Armand, “Form and Essence in the Philosophy of St. Thomas,” in idem, Being and Knowing (Toronto, 1990), 3–18.Google Scholar
59 For the interesting suggestion that in adapting Aristotle's view of form, Aquinas weakens his view of the intellectual substance as the form of the human body, see Abel, Donald C., “Intellectual Substance as Form of the Body in Aquinas,” Proceedings of the American Catholic Philosophical Association 69 (1995): 227–36.Google Scholar
60 In each case reasons are given for why the incorporeal human soul and intellect cannot be united to a body. The second and third objections are that an intellect could not attain universality if it is united to a body. The fourth is that since intellectual power is incorporeal, it cannot extend to what is corporeal. The fifth is that since the intellect possesses its own being, it cannot be the form of something that must receive its own existence. The sixth is that since form cannot exist without matter, the intellectual principle would stand in need of matter, which it does not. Similar arguments appear in the fifth and sixth articles (ST 1.76.5–6).Google Scholar

62 For a clear philosophical account of question 76 that makes no mention of the Cathars, see Kenny, , Aquinas on Mind (n. 3 above), 145–55.Google Scholar
63 It is interesting that while Aquinas praises Avicenna for viewing matter as an aspect of the human species, he criticizes him for having a Platonic view of human understanding that neglects the role of the bodily organs (SCG 2.74). The criticism is that Avicenna placed too high a value on transcendent forms in his account of human understanding at the expense of the material elements. For my purposes, it is important to keep in mind that opposition to Avicenna on this point also responds to the Cathars. Since the Cathars were thought to use the arguments of Plato, responses to them often apply to the Cathars. For a clear account of Aquinas's criticism and further citations from Aquinas and Avicenna, see Lee, Patrick, “St. Thomas and Avicenna on the Agent Intellect,” Thomist 45 (1981): 41–61.Google Scholar
64 Cohen is right to point out that Etienne Gilson failed to devote attention to this point in his classic The Christian Philosophy of St. Thomas Aquinas. Cohen's interpretation has justly received favorable attention. For example, Martin Tweedale agrees with his analysis and attempts to clarify how material form comes to exist spiritually in the understanding, and James Robb confirms that scholars with an interest in defending intelligibility have neglected this side of Aquinas. Yet the traditional picture continues to be influential in works such as The Cambridge History of Later Medieval Philosophy and Marenbon's Later Medieval Philosophy. Slight attention is paid to the material elements in The Cambridge Companion to Aquinas, with no mention of Cohen's work. See Cohen, Sheldon M., “St. Thomas Aquinas on the Immaterial Reception of Sensible Forms,” The Philosophical Review 91 (1982): 193–94; Gilson, Etienne, The Christian Philosophy of St. Thomas Aquinas (New York, 1956), 203–4; Tweedale, Martin M., “Origins of the Medieval Theory that Sensation is an Immaterial Reception of a Form,” Philosophical Topics 20 (1992): 215–31; Robb, James, “The Unity of Adequate Knowing in St. Thomas Aquinas,” Monist 69 (1986): 447–57; Mahoney, Edward P., “Sense, Intellect, and Imagination in Albert, Thomas, and Siger,” in Kretzmann, Norman, Kenny, Anthony, and Pinborg, Jan, eds., The Cambridge History of Later Medieval Philosophy (Cambridge, 1982), 605–7; Marenbon, John, Later Medieval Philosophy (1150–1350): An Introduction (London, 1987), 116–31; and Kretzmann, Norman, “Philosophy of Mind,” and Scott MacDonald, “Theory of Knowledge,” in Kretzmann, Norman and Stump, Eleonore, eds., The Cambridge Companion to Aquinas (Cambridge, 1993), 128–59 and 160–95, respectively.

66 SACV 426. On Aquinas's view that material things are known in the soul without matter, see ST 1.84.2; on Moneta on seeing color, see SACV 426. Moneta denies that the eyes receive material form, and Aquinas denies that the intellect receives material form (ST 1.75.5). On the material origin of ordinary human sight and understanding, see SACV 103.Google Scholar
67 Moneta also discusses the composite nature of human knowledge when arguing for the immortality of the human soul (SACV 422–29). A philosophically interesting argument is offered for why the human soul is not a composite of form and matter. Using Aristotle's distinction between form and matter and a discussion of the eye receiving but not becoming white, Moneta explains that no intellectual substance can consist essentially of material form (SACV 426). Aquinas uses the same argument when arguing that the soul does not consist of matter and form (ST 1.75.5). Moneta's discussion indicates the contemporary polemical nature of this discussion.Google Scholar
68 For example, when arguing for the material nature of Christ's miracles, Moneta distinguishes between healing material eyes and spiritual eyes. Spiritual eyes do not need to be opened in order to see (SACV 103). In fact, it is important for Moneta to point out that Jesus' lordship over all of material creation is shown by effected miracles at each level of nature: non-living, plant life, sensing, and the rational (SACV 100–104). This gives Moneta a reason to put Aristotle's categories to use in his polemical project. Google Scholar
