Michel Foucault in Les mots et les choses (literally Words and Things, 1966; English tr. The Order of Things), the book that made him a celebrity in France and raised the brewing French controversy over so-called “structuralism” and humanism into high gear, argues that there was a major paradigm shift from resemblance to more abstract representation at the beginning of the classical age (17th century). More recently, Robert Brandom has focused more specifically on Descartes’s analytic geometry as based on a global isomorphic representation of geometry in terms of algebra, which replaced the medieval paradigm of resemblance.
Certainly the notion of representation plays a fundamental role in both Descartes and Locke. Foucault made a huge impression on me when I first read him around 1979, and — as witnessed here — Brandom is one of my current leading lights. But Foucault and Brandom are both just wrong about the middle ages being simply dominated by a paradigm based on resemblance.
While I have several times referred to L’Être et représentation [Being and Representation] (1999) by Olivier Boulnois, I have yet to more substantially work here on this important book, which details the rise of the notion of a “science” of metaphysics as ontology — closely associated with an abstract notion of representation, not reducible to resemblance — in the later middle ages. This offers a vital corrective to the rather ahistorical global generalizations commonly applied to these topics.
On Boulnois’s account, which involves a cast of many, the leading character in these developments will be the theologian John Duns Scotus (1266-1308). Boulnois is a leading scholar and translator of Scotus.
I would note that this substantial work on Scotus also seems to thoroughly invalidate the thinly documented valorization of the Scotist univocity of being by Gilles Deleuze. It is hard to think of a writer more viscerally opposed to the representationalist paradigm than Deleuze. Deleuze’s other valorizations of Spinoza and Leibniz and the ethical notion of affirmation in his early Nietzsche book influenced me in the past. But to my knowledge, Deleuze never even mentions the central role of representation in Scotus and its strong connection with univocity. I felt betrayed when I discovered this.
“To represent means at once to ‘make present’, ‘stand in place of’, ‘resemble’. Precisely, in the Middle Age the vocabulary of repraesentatio is used frequently, in all of these senses” (Boulnois p. 7, my translation throughout).
The point here is not to deny that resemblance plays a major role in medieval thought. It is rather that — as with several other notions commonly associated with modernity, such as a psychological Subject — the later middle ages already saw substantial and systematic use of a more abstract notion of representation.
“Already in Tertulian, the statue of Hercules ‘represents’ Hercules … it indicates his presence in absence — it takes his place. To represent is in a certain way to make present, and Maxim of Turin uses these two terms as synonyms. The liturgical use of the term follows naturally…. A new turn appears in the Cistercian order with Aelred of Rievaulx, as a meditative exercise that makes Christ present in the imagination” (ibid).
In spite of the visual or visualizing character of these uses and their association with notions of resemblance, there is clearly more going on here than just the application of a criterion of resemblance. We see explicit theoretical development centered on the notion of representation.
“But the text that durably imposed the vocabulary of representation seems to be the Latin translation of the De Anima [On the Soul] of Avicenna: the expression appears at least seventeen times in this work…. It is indeed repraesentatio that bears all the difficulty of the platonizing noetics of Avicenna…. In this way the problematic rejoins the central difficulty of another Platonism, that of Augustine, which has to understand how the soul, always spiritual, can have sensible images without losing its spiritual nature…. [T]he problem of representation obliges us to explore the confluence of Augustinianism and Avicennism” (pp. 8-9).
Representation is a fundamental concept of Avicenna’s elaborate psychology, which combines Platonic, Aristotelian, and medical elements. (Avicenna was the second greatest medical authority in the middle ages, after Galen.)
The historical importance of the adoption of Avicenna by later medieval Augustinians was already pointed out by the great Thomist scholar Etienne Gilson in the early 20th century.
“The Middle Age explains repraesentatio by its equivalents: stare pro (taking the place of) — signs take the place of things that cause them and to which they refer; supponere pro (supposing for) — in a proposition, the terms take the place of the thing to which they refer; similitudo, species, imago (being a resemblance, an image) — the sensible species, the phantasm, the concept representing the object they resemble; supplere vicem (playing the role of) — abstractive knowing takes the place of the object” (p. 9).
The role of signs in thought and language was already discussed by Roger Bacon in the 13th century. The theory of “supposition” was an important and sophisticated Latin innovation that anticipates modern referential semantics. Theories of “species” were another major non-Aristotelian Latin development, possibly derived from Stoic physiological-epistemological theories of phantasia.
“We need to ask ourselves about the logical, optical, and noetic status of representation, corresponding to the functions of the sign, of the sensible image (species or phantasm), of the concept. Taking the place of, being the image of, resembling, conceiving are diverse regimes that need to be studied in their own right. Then we need to rearticulate these terms one to another, and ask ourselves how the representation of being is constituted successively as a semantics, an eidetics, and a noetics. In a theory where concepts are themselves signs, where they also have sensible species for content, these three dimensions form a coherent system” (pp. 9-10).
His reference to the “representation of being” here anticipates what we will see as the Scotist approach to being in terms of representation. Roger Bacon treats concepts as signs.
The Latin middle ages saw huge development in logic, semantics, the theory of signs, optics, and noetics. Scholastic interest in logic is well known, and we have seen at least a taste of medieval noetics in the disputes about Aristotelian intellect. There was major development in geometrical optics in the Arabic-speaking world, and in the medieval and Renaissance Latin world. Representability is the minimal criterion of univocal being in Scotus.
“But it is also necessary to examine its genesis. What form of concentration allowed signification, knowledge, and thought to be re-expressed using only the concept of representation? And what changed in the notion of representation to make it possible to represent all things in a unique way? Researching the origin of a metaphysics of representation is not to write the history of the concept of representation, but the genealogy of a new structure, the thinking of being by representation” (p. 10).
Here I think he is onto something important. These discussions have a multi-dimensional aspect that is clearly not reducible to a notion of simple resemblance.
We will see that a “metaphysics of representation” and a “thinking of being by representation” are especially characteristic of Scotus, but not only Scotus.
Metaphysics “gets a new formulation in the tradition that goes from Roger Bacon to Duns Scotus, often identified with the English Franciscan school of the 13th-14th century. I hope to show that this is too restrictive, because the problematic plunges its roots further in the Augustinian and Avicennan ground and overflows this school, since we find important elements in Thomas Aquinas or Henry of Ghent” (ibid).
“With these distinctions made, it will be possible to measure the mutations of metaphysics that result. It gets its modern status as a science thanks to the concept of being, which allows Henry of Ghent to know all things in one sole act of thought, and in Duns Scotus replaces the analogy of being by founding its univocity: the unity of metaphysics rests on a noetic unity. We need to investigate that which gives priority to the concept, a unity engendered by intellect, with the power to represent all its meanings in its stable identity” (ibid).
By “modern” here, he means early modern. It is important to note that the disrepute of metaphysics and widespread talk about surpassing it came later. The early moderns generally claimed to have a new and better metaphysics. This will turn out to have Scotist and other scholastic roots.
I did not recall Boulnois’s use of “concept” in this context. This will be something to watch. In the context of univocal being and intellectual intuition of individuals, “concept” has a completely different sense than it does in Hegel or Brandom. By “concept” here, he seems to mean a mental representation that could be simply given as an atomic thing. It is important to note that the term “concept” can also be given a non-mentalist, non-representationalist, and relational rather than atomic interpretation in terms of conditions of use and consequences. This is a fundamental theme in Brandom’s work.
“This study aims at the same time to propose a new interpretation of the history of metaphysics. With the conceptual unity of being, it seeks to understand that which constitutes the invisible foyer and hidden sub-basement of modern philosophy” (ibid).
“This study is centered on the affirmation, more Avicennan than Aristotelian, that the ens can be apprehended in a unique concept, which leads to the univocity of the ens. The object of metaphysics thus becomes the first object of thought in the order of conception (first adequate object: being) and not the first object in the order of perfection (first object by eminence: God)” (p. 12).
Ens is the present participle of the verb esse, “to be”. Implicitly it refers to an individual entity, a particular “being”. This will be related to claims of knowledge by intellectual intuition of individuals as individuals. In this context, claims of univocity go hand-in-hand with claims to univocally know by intellectual intuition. “Concept” here seems to be tied to intellectual intuition, whereas in Kant and Hegel the two are sharply opposed.
“Contemporary studies of ‘modern metaphysics’ from Suárez to Kant (Schulmetaphysik) show that the classic articulation of metaphysics into metaphysica generalis and metaphysica specialis rests on a discreet but decisive acceptance of the univocity of the concept of being, particularly in Suárez. Thus modern metaphysics acquired the status of a science and a univocal constitution thanks to the concept of ens in Scotus, which replaced the analogy of being. The univocity of being comprehended in a unique concept remains the principal turn in the history of metaphysics…. This structure imposes itself from the 14th to the 18th century, passing through the work of Suarez and Wolff” (p. 13).
The bad idea here is that a being has a concept, straightforwardly and univocally. This is antithetical to Aristotle, for whom the very beginning of wisdom is that things are said in many ways. I have occasionally invoked “beings” as objects of Aristotelian phronesis, which is all about grasping particulars in an open way that is not locked in to a univocal “concept”.
