Descartes belongs to which trend in modern philosophy

Well, by conventional definition, Philosophy is the rational investigation of the truths and principles of being, knowledge, or conduct. This, while providing a contextual definition of the word philosophy, just scratches the surface of its actual meaning. First, we begin by summarizing and comparing the theme of their works for similarities so as to better form.

A Humean Critique of Descartes Montreal has big potholes. Lots of them. If one is to truly understand the philosophy of Hume and Descartes, one must understand what they would do with crummy roads as civil engineers in Montreal. Hume would probably repave the roads based on the success of past designs and the results of empirical data. Descartes, on the other hand, would probably leave nothing unscathed after attacking the problem with reason, scrapping the existing roadmap and re-building roads.

Countless philosophers show a way of clarifying what is real and what life is meant to be. Sewell applies Rachel Levy's , pp. For a detailed account of how the theological poets created imaginative universals, see Grant Croce calls the aggregate of ideas contained in the verum ipsum factum the initial form of Vico's theory of cognition. According to Vico, we have true knowledge when the thinking and the doing are performed by the same person.

As a master-builder of a new intellectual system, Descartes decides that it is far better to simply level the old building of ancient learning and start all over ibid. Descartes, in fact, envisions in the immediate future a group of artisans who will adopt and follow his method, building upon the secure foundation laid by the master-builder himself ibid.

This set of methods is to be applied to all human endeavors. The metaphors of wise traveler and master-builder, coupled with his claims to having laid a new foundation for the sciences in the Discourse and the Meditations , demonstrate that Descartes envisioned nothing less than the complete unmaking and remaking of the intellectual world he inhabited.

While both the title of the Discourse and the Rules for the Direction of the Mind Descartes suggest that Descartes will develop a procedure for study, the procedure for study in all academic fields, the Discourse itself turns out to be an apologia for his life and works. It is not so much what humans understand, but what they do not understand that accounts for a large part of what we call culture.

And if we were all quite honest we would admit that there is still much about human activity that befuddles philosophers, historians, sociologists, anthropologists, and psychologists. Vico's theory of knowledge seeks to include the sciences and the humanities in an attempt to account for all human activity including myths, legends, laws, and institutions.

This is the very same connection a number of scholars in leadership studies are attempting to remake today. The editors of the Leadership and the Humanities journal, for example, seek to connect the insights about leadership brought by the social sciences with the insights brought from the humanities.

Certainly not Ferraris or Gabriel, who reject it on principle as a barrier to knowledge; certainly not Meillassoux, who reduces the thing-in-itself to something that merely outlasts us in time. Not Latour or Whitehead, who treat the real in relational terms and allow no excess beyond relation, even if Whiteheadians tend to contest this point vigorously. That is to say, the usual manner of trying to get beyond Kant is along the lines of German Idealism.

But he can be forgiven, since he did so many other important things, and luckily his successors cleaned up the thing-in-itself problem for him. The reason why so many are reluctant to take this step, which has been explained and promoted by OOO authors for nearly a generation, is because it so openly flouts the division of labor at the heart of modern thought.

This is what science already does! Philosophy should stick to the thought-world relation where it belongs.

The real and the unreal cannot be taxonomically aligned with individual discplines, since both the real and the unreal are present everywhere at all times. Like so much else in this period, the term is grounded in the ideas of Kant. As far as I am aware, he uses the term explicitly only in the Second Critique, where it means both that ethical actions must be walled off from their consequences, and that ethics has to do with the general form of the categorical imperative rather than more specific ethical rules.

The beautiful must be walled off from both the agreeable and the politically beneficent: unlike Jean-Jacques Rousseau, Kant thinks it no obstacle to the beauty of a palace that the masses suffered to enable its construction. Namely, he is not interested in the theme of autonomy per se but only in one specific kind of autonomy: the independence of thought and world from each other.

The problems with Kantian formalism did not escape the notice of later thinkers, and I have argued elsewhere that each of his three Critiques eventually found a critic equal to the work. I speak here of Fried, whose turn from criticism to history did not initially change his sentiments.

In his first historical work, on anti-theatrical painting in the age of Denis Diderot, Fried continued to uphold a crucial gap between the beholder of the painting on one side and the absorbed figures within it on the other. Rather than conceding any sort of autonomy of thought and world from each other, Dante depicts a world of amorous agents who are not only fully deployed in their loves and hates for various people and objects, but are even judged for it.

To give an example that is not my central one, consider the case of Maurice Blanchot. During my doctoral student days in the early s, the impression was often conveyed that Blanchot was a major piece of the philosophy of the future.

Needless to say, almost thirty years have passed, but Continental philosophy has not become noticeably Blanchotian. Paul de Man, writing much earlier than , offered the following note of praise:. When we will be able to observe the [post-war] period with more detachment, the main proponents of contemporary French literature may well turn out to be figures that now seem shadowy in comparison with the celebrities of the hour.

And none is more likely to achieve future prominence than the little-publicized and difficult writer, Maurice Blanchot. This high regard for Blanchot was not rare in the circles frequented by de Man. Derrida and his intellectual kin ruled early s Continental philosophy in almost crushing fashion, in a way that is difficult for young people today to imagine. In such an evironment, who would have seemed a better heir apparent for a few decades down the line than Blanchot?

For in some ways he is simply a darker, eerier version of Derrida, more turbulent and paradoxical but never casting dangerous light on anything missing from Derrida himself.

A pair of related remarks from important authors come to mind. The other relevant passage, which I am currently unable to locate, comes from Marcel Proust in his great multi-volume novel. Somewhere in those thousand of pages, Proust remarks that we tend to imagine the future as some sort of intricate variant of the present, failing to realize that the future springs from hidden factors in the present that are not currently manifest.

In any case, Blanchot is the philosopher of the future, and always will be. But my concern is not so much with Blanchot, whose futuristic rose has faded since my youth. Instead, I wish to propose a related maxim that might well annoy some readers: Schelling and Merleau-Ponty are the philosophers of the future, and always will be.

Schelling and Maurice Merleau-Ponty are two of the most colorful thinkers in the whole modern period. There is still an air of the twenty-second century about them; we would not be surprised to hear science fiction characters discuss their work.

Schelling always smells like the faint promise of an overturning of the largely Hegelian history of the nineteenth and twentieth centuries, and the consequent emergence of a parallel intellectual universe. The more that analytic philosophers of mind seem to become interested in him, the more this seems to verify that Merleau-Ponty is on the track of whatever has somehow always eluded us until now. The problem is that both Schelling and Merleau-Ponty are modern onto-taxonomists to the core.

They are projections of how we once thought the future should look, like pre-color films of s Manhattan with hovercraft roaming the streets and lasers striking down villains. More likely than not, your future philosopher is a phantasmatic image of the place where you already stand—as when hopeful fathers imagine their infant sons following in their professional footsteps someday, but with more success.

Heidegger had some sense of this problem, as we find in one of his passages on ambiguity in Being and Time :. Already everyone has surmised and scented out in advance what Others have also surmised and scented out. We need to stop looking toward the horizon, and reflect instead on the major prejudice in our midst.

Why is there is only one possible exit from modern philosophy? Because modern philosophy lives and breathes from a single basic principle: the notion that thought and world are the two poles of the universe, the first of them immediate and radically certain, the latter less certain but impressively masterable by science.

But in this way, the rift between immediacy and mediation—which I do accept—is wrongly identified with two specific kinds of beings. What is immediately knowable are entities in their sensual realities, as related not just to thought but to anything else. What is not immediately knowable, but only detectable by indirect means, is the surplus in any reality that is not exhausted by its relations with anything else. This means it should be non-literal in its outlook, since to reduce anything to its pieces undermining and to reduce anything to its effects overmining are equally defective maneuvers.

Literal language succeeds by ascribing properties to entities that they truly have. But since entities are more than bundles of qualities, they are never literalizable. This is why philosophy is philosophia , not sophia.

To argue that philosophy should be non-relational does not mean that relations do not occur. If every entity is a compound not a hybrid, as Latour claims then every entity is formed from relations between components, without being nothing more than these relations.

And if every entity can affect other entities, it does not follow that entities are nothing more than the sum of these effects. Among other things, this is why arguments since the s over formalism in the arts often seem to go nowhere. The work with its small circle of relations actively fends off any probings from the outside, so that further relations require genuine labor.

The reason why things are inherently non-relational, even when they relate, is that no form can be moved from one place to another without change. Against this notion, OOO holds with Latour that there is no transport without transformation. In this age of resurgent materialism, we need less materialism and more formalism. Althusser, Louis.

The reader with a specialized interest in Descartes may already find sufficient reason to proceed. But, as the preceding considerations have already suggested, there are larger reasons for pressing ahead with the question of imagination. The first has to do with Descartes. The Sixth Meditation's dismissal of the possibility that imagination is essential to us as thinking things and its recognition of the cognitive weakness of imagination do not establish the irrelevance of imagination and images to the later Descartes.

Throughout his career Descartes attributed a key role to imagination in mathematical and physical thinking. In the last work he published, the Passions of the Soul, he allowed it a notable function in the mastery of the passions. In the Meditations he put imagination to work in the very act of transcending it, and he took ordinary imagination as an analogical model for conceiving.

One must therefore think through the conflict of interpretations one has grown up with by means of the models of acquired and secured truth that have been previously recognized and cultivated. One need think only of the use he made of the "malign genius" at the end of the First Meditation to recognize that radical doubt itself is an imaginative, or at least an imagination-like, function.

As for imagination's role as analogical model for the workings of the thinking thing, one might read the "Responses" to the third set of objections to the Meditations, where Descartes tells Thomas Hobbes that he chose the term 'idea' because it is used "by philosophers for signifying the forms of perceptions of the divine mind, although we recognize no phantasia in God' AT VII Ideas are like the forms of God's imaginings, if God had imaginings—which of course he doesn't!

Even if over the years Descartes reconceived or downgraded the importance, especially the cognitive importance, of imagination, the response to Hobbes suggests that for an adequate understanding of so Cartesian a notion as 'idea' we must consider it in the context of imagination's functions. A further motivation for pushing forward in this study is provided by remarking that imagination is just one of what medieval and early modern thinkers called internal senses and that, as we shall see, some of its functions in Descartes are closely related or even identical to those that had traditionally been assigned to the cogitativa, the internal sense in which cogitation proper begins.

In the Regulae ad directionem ingenii, the term imaginatio in fact appears on one occasion as a direct synonym of cogitatio, which at the very least reinforces the suspicion that Descartes's pre understanding of psychology provides a context out of which the later philosophy might be more accurately understood.

It would, after all is said and done, be hard to argue that Descartes's understanding of cogitatio is a matter of only minute historical interest—not when the truth that resists the corrosiveness of hyperbolic doubt and marks the beginning of modern philosophy is formulated "cogito, ergo sum. But we can press beyond Descartes scholarship and history of philosophy conceived narrowly to the question of his influence and role in Western intellectual culture.

The constellation of the internal senses, from common sense to cogitation, was part not just of philosophy but also of the medical and scientific understanding of the sensitive and cognitive abilities of human beings, in particular of the relationship between body and mind or soul. The doctrine of internal senses constituted an intellectual commonplace well into the seventeenth century, but in the wake of Car-tesianism it underwent rapid disintegration and was displaced by radically simplified schemas.

Unlike the Cartesians, that is, his followers, Descartes began his philosophic and scientific career solidly rooted in this earlier tradition. If there was a Cartesian turn in Western thought,.

Descartes himself was the first to accomplish it, and perhaps he was the only person ever to accomplish it in a thoroughgoing, philosophical way.

Seeing how this happened may help us recognize questions about Descartes and modernity that have never been adequately explored. Not least of the advantages we could gain might be a more concrete and less demonized version of the classic Descartes, whom it is popular to stigmatize as originator of a host of modern evils.

The final reason I shall cite for pressing forward has to do with imagination itself and its place in the economy of human being and human life. Today no aspect of mind has comparable power to elicit by the mere mention of its name a wide and curious audience, both intellectual and popular. It names a power that many people think can save them, if not the world; they believe that "the results of an ever greater triumph of the imagination can only be good. Eva Brann, in a work that attempts to bring into focus the vast philosophical, psychological, and aesthetic literature on imagination, remarks that Western tradition assigns imagination "a pivotal function.

It is placed centrally between the faculties and intermediately between soul and world. Thus it both holds the soul together within and connects it to the objects without. Yet the treatment given this great power even by habitually definitive authors like Aristotle and Kant is tacitly unfinished, cursory, and problematic.

The imagination appears to pose a problem too deep for proper acknowledgment. It is, so to speak, the missing mystery of philosophy. It is risky to put great hopes in any one thing. There is the danger of asking from imagination, by nature a middling power, more than it can possibly deliver.

It cannot, for example, supplant the extremes that it mediates. In order to understand, we must have recourse to abstraction and concepts, but there must also be real objects of understanding situated in a world that is experienced by sense before it is imagined. We cannot think in images alone, nor can we live in them.

Yet it sometimes seems to even the most tough-minded thinkers that imagination has a force able to deepen understanding and enliven ordinary experience. Few have had such high hopes for imagination as Descartes, and few who have entertained such hopes have ended by so narrowing its application. Yet imagination always retained for him a paradigmatic aspect: he.

Girard ascribes this sentiment, which he does not share, to "romantics and neoromantics' alike. Perhaps it is not too fanciful, here at the outset, to wonder whether it is precisely owing to the closeness of imagination to our thinking, acting being that we set such great store by it and at the same time are unable to give more than a fragmentary or oblique account of it.

Much of what Descartes has to say about imagination is fragmentary and oblique. Is this because his understanding is inadequate? Or is it because there is something about imagination that encourages, even demands, indirection and partiality? Are human beings capable of a complete, discursive understanding of imagination?

Although this book cannot aspire to answer each of these, it will, I hope, give insight into the phenomenon of imagination—the silent center of this investigation—and the questions surrounding it.

At the very least, by trying to think imagination along with Descartes, by tracing out the career of the imagining Descartes, we can gain not just perspective on the evolution of a single thinker but also insight into the workings of this deeply rooted power, the source of much promise and many perplexities.

In the introduction I mentioned Descartes's indebtedness to a tradition of philosophical psychology that placed so-called internal or inward senses between the five external senses and the powers of intellect. The purpose of this chapter is twofold: 1 to introduce the chief elements of the doctrine of the internal senses and situate the imagination within it and 2 to demonstrate the connection of the psychology and physiology of understanding elaborated in Descartes's Regulae ad directionem ingenii to this tradition.

As we shall presently see, although at first glance the psychophysi-ology of the Regulae reads like an anticipation of the later theory of the pineal gland as the seat of the soul in the body , it is in a more original sense an outgrowth of the doctrine of internal senses. Imagination is a name traditionally given to one of the powers of the mind enumerated in so-called faculty psychologies, [1] which divide the human soul according to fundamental capacities.

Most medieval discussions follow Aristotle in taking the vegetative, sensitive, and intellectual parts as. The central issue for a psychology of faculties is not whether mind or soul is thought to have various functions but the degree of independence of these functions from higher powers.

For example, if the senses are thought to operate in essential independence from intellect, then sensibility is an independent faculty; intellect, in its turn, might function independently of sense, for instance insofar as it does not require the immediate action of the senses. As soon as one allows even a small degree of independence to a function, one has in fact taken the first step into a psychology of faculties.

The intellectual power, for instance, can be divided, according to its mode of operation, into intellect, which is immediately apprehensive, and discursive reason, which proceeds by stages; or, emphasizing instead the object toward which the faculty is directed, one can divide it into the three capacities of knowing l what is changing, 2 what is unchanging but material, and 3 what is unchanging and wholly immaterial.

The sensitive powers include not just the five external senses of sight, hearing, touch, smell, and taste but also the internal senses.

Although there was no little disagreement about the precise number of the internal senses, their proper names, their organic locations, and the correct delimitation of their functions, there was sufficient consistency in medieval presentations for us to abstract a core theory. The core theory ultimately derives from Aristotle but has admixtures from other philosophical traditions and incorporates scientific and medical doctrine as well. In a first approximation we should note that the sensitive powers, which human beings share with other animals, are intermediate between the vegetative-nutritive-reproductive powers possessed by all living things and the intellectual powers possessed at least among physical beings only by humans.

In contrast to the vegetative powers, the sensitive powers involve an awareness of things, or at least of aspects of things. Awareness does not make them intellectual, for the intellectual powers proper operate at the level of abstractions, universal concepts, and generalizations, whereas the sensitive powers deal with sensory aspects of singular things.

Still, there can be more than a superficial resemblance to understanding in animal sensibility. This is evident not so much from individual sensations—seeing a color, hearing a tone, smelling an aroma—as from the ability of animals to use multiple sensations of the same and different types, to compare and remember them, in order to survive and prosper.

So, for example, most mammals learn from a small number of incidents to avoid situations that produce unpleasant effects, and they can make discriminations in their environment that permit them to secure food and shelter and to raise their young. Although some might be inclined to call these abilities forms of intelligence and to treat them as in essence intellectual, the tradition I am describing saw these as closer to the external senses than to intellect. Nevertheless, they opened the way to the conception of a deeper kind of sensibility that is crystallized in the internal sense tradition.

The second and third books of De anima develop a theory beyond the vegetative of the sensitive and cognitive powers of soul: the five external senses, the common sense aisthesis koine , imagination phantasia , receptive intellect nous pathetikos , and agent or productive intellect nous poietikos. This cognitive psychology was predicated on the existence of forms in substances for our purposes 'substance' can be taken to mean physical objects, though for Aristotle there are immaterial substances, too : an essential form, which constitutes the nature of the thing and makes it the kind or species of thing it is e.

It must not be thought that this communication of forms necessarily occurs through local motion or that it takes time, say by means of an "Aristotelian photon" flying through space from object to sense. Aristotle does not, for example, conceive of vision as being due to the transmission of little objects or impulses.

Rather, a proper sensible in the object, for example its color, acts on the organ when the medium between them, in the case of color what Aristotle calls the diaphanous or transparent, is made actually transparent by light. In darkness, transparent materials are only potentially diaphanous, and so colors cannot be communicated to the eye; but light activates the medium, thus enabling it to be the means through which the sensible form communicates itself to the sense organ.

To use the classic formula, the sense in act is the sensible object in act; that is, the sense of sight as it is actually engaged in seeing is the same as the activity of the sensible form of the object which is communicated. But the evidence of Aristotle's text justifies locating sensible forms in the object. A further step away from the Aristotelian conception would be to consider the rays not as a medium but as makers or stimulators of color the early modern scientific notion of color as understood by Galileo, Descartes, and Newton.

Or to use the image that anticipated Descartes's use of it in Rule 12, AT X by nearly two thousand years, "every sense is receptive of the forms of sensible objects without their matter, and in a sort of way in which wax receives the impression of a signet-ring without the iron or gold, for the wax receives the impression of the golden or bronze [ring] not qua gold or qua bronze" al; brackets in source.

Between his discussions of the five senses and intellect, Aristotle introduces two other powers that, with the addition of memory, initiated the internal senses tradition. The first is common sense, so named because it is that part of sense in which the common sensibles like motion and shape are perceived. The eye receives not just color but also motion, rest, number, shape, and magnitude a but itself perceives only what is proper to it, color.

Another power is therefore needed in which the common sensibles can be perceived alongside the proper sensibles and in which the sensibles from all the different sense organs are brought together into a unified field of perception. Vision by itself recognizes not objects as such but colors; hearing recognizes not things but sounds; and similarly for the other external senses.

But to recognize that this white, crystalline stuff, called sugar, is sweet, to recognize that an assemblage of colors is a thing, and to recognize that a particular object has such-and-such characteristics is perceived not by any individual sense organ but in the common sense. The justification for this faculty is perhaps clearest from the need to coordinate and compare the information [7] of the different senses. We can not only see with our eyes but also feel by our touch that a thing is moving, round, or large, and these two "channels" of information are perceived as referring to a single thing.

Neither the eye nor the tongue is able to judge that the white stuff we call sugar is sweet the eye perceives whiteness but not sweetness, the tongue sweetness but not whiteness. The common sense is able to do these things because it is where the different sensibles are unified.

The common sense, we might conclude, is the repository of the unified image of sensation. But we also have images when we are not directly sensing things, and this justifies introducing another sensitive power preced-. Hippocrates G. Apostle Grinnell, Iowa: Peripatetic Press, There is debate about whether imagination is really a faculty for Aristotle, [8] but we can by and large ignore this, since for the vast majority of Arabic and Latin commentators there was no doubt that it was a faculty—which is not to say that they thought there were no difficulties of interpretation.

Difficulties arise not least because Aristotle's discussion of imagination is dialectical and problematical. Most of the third chapter of book 3 of De anima cited below as De anima III 3 is devoted to distinguishing imagination from external sense, common sense, opinion, belief, knowledge, and intellect, with due regard given to possible connections to these.

Put summarily, Aristotle argues that if imagination, the power or habit by virtue of which images are formed in us, is a power of discrimination, it is nevertheless different from other discriminating powers, like the external senses and common sense, because it does not require the presence of an object, although it does depend on the previous activity of these i.

Because imaginings are not inherently true, imagination must also be differentiated from the cognitive faculties that are always true, like knowledge and intellection. It is not identical with or a variety of opinion, nor is it a mixture of opinion and sensation, because conviction and reason always accompany opinion, whereas neither is necessary for imagining.

He concludes that imagination has not so much to do with the proper activities of the senses—which are infallible with respect to the proper sensibles when the eye sees red it is really seeing red —as with the attribution of proper sensibles to objects and the discrimination of common sensibles, which are sometimes false.

Like the external senses and the common sense, imagination is of the sensible; but its objects need not be immediately present, and it is responsible for or related to the persistence and the repeatability of images. This account of De anima III 3 leaves many questions unresolved. It is not entirely clear, for example, what it means for imagination to be a. Martha C. Since images persist in imagination, it would seem to have some significant relationship to memory, although that is not pursued in De anima, [9] and it appears to overlap the common sense in that it deals in matters of the unified sense one would assume with different functions.

The obscurities and unresolved questions would by themselves have occasioned at least some elaboration from commentators. But the deepest reason for the persistence of interest in Aristotle's doctrine of phantasia was a claim made in De anima III 7 that puts imagination at the heart of knowing itself. Images are to the thinking soul like sense impressions. But when [the thinking soul] affirms or denies them as good or bad, it pursues or avoids, respectively, and for this reason the soul never thinks without images.

The thinking part, then, thinks the forms in the images; and just as what is to be pursued and what is to be avoided [when the sensible objects are present] is determined for it by the corresponding [sensations], so it is moved when images are before it and there is no sensation.

For example, sensing a beacon as being fire, it knows by the common faculty of sensation that the enemy is approaching when it sees the beacon in motion. At other times, it forms judgments and deliberates about future objects relative to present objects by means of images or thoughts as if it were seeing these objects; and whenever it asserts that [certain objects imagined] are pleasurable or painful, it pursues or avoids [those objects] as it does when it senses objects; and it does so in actions in general.

There is no thinking without images, without phantasms. The word for thinking here is dianoein, which in Aristotle implies judgment, the discursive thinking that combines or divides two things; in De memoria et reminiscentia the same statement is made of noein, which embraces both discursive thinking and the intuitive grasp of simple things terms or concepts, the elements that discursive thinking combines in judgments.

An account has already been given of imagination in the discussion of the soul, and it is not possible to think without a phantasm. For the same affection occurs in thinking as in the drawing of a diagram.

In the latter case, even though we are not also using the triangle's being determinate in quantity, nonetheless we draw it determinately as to quantity. In just the same way, the person thinking, even if he is not thinking of quantity, places [a] quantity before his eyes, but does not think of it qua quantity. Even if the nature [of what he is thinking] is among the quantities, but indeterminate, he places before him a determinate quantity, but thinks of it qua quantity only.

Quoted after Lachterman, The Ethics of Geometry, But in the same passage of De anima he notes that "objects which are outside of the sphere of action, too, i. What the original statement means, then, is that all discursive thinking—all thinking of any kind, if we take into account the passage from De memoria et reminiscentia —requires phantasms, and images are important not just because they are fundamental to the activity of comparison that underlies judgment but also because it is from images that the form or essence of a thing is arrived at, is abstracted.

Moreover, chapter 7 leaves open the question of whether it is even possible for the intellect to think an object separate from matter. Chapter 7 of book 3 corrects an impression that one can easily get: that the treatment of phantasia in chapter 3 was included for the sake of completeness rather than intrinsic importance, since chapters 4 and 5, which treat the crucial topics of receptive and agent intellect, make no reference to images.

But those latter two chapters are dedicated chiefly to continuing the differentiation of soul powers from one another that began in book 2. Accordingly, they identify the factors that differentiate intellect from other parts of the soul and distinguish the intellect according to its activity agent intellect and potentiality receptive intellect. Understanding the nature of the twofold intellect was one of the chief and most controverted parts of Aristotle's De anima for the Middle Ages.

This was not just because of the importance of the question of knowing but also because it bore on the immortality of the soul and its relation to. But whether the intellect, which is not separate from magnitude, can or cannot think any separate object is a matter to be considered later" De anima, b The question is not treated subsequently in De anima; one might consider the discussion of thought thinking itself in the twelfth book of Metaphysics as decisive, but even there the question might be raised whether human beings can truly think what is separated from matter.

For Aristotle, everything that is not unchanging needs to be understood in terms of potentiality and actuality, and since human intellect is sometimes understanding and sometimes not or sometimes understanding one thing, sometimes another , there must be a cause of this change from one to the other state. Chapters 4 and 5 of book 3 show that in intellection cause and effect are ontologically correlative. God, inasmuch as Aristotle had stated that although all the other faculties pass away with the animal body, the agent intellect is apparently separate and unchanging.

In what follows I shall by and large leave untouched the questions of immortality and of whether the agent intellect is part of the human soul or instead a divine emanation as in Avicenna or even God himself.

My focus will be the interpretation of the process of cognition. Rather than continue here with an analysis of Aristotle himself, we can now turn to Avicenna's interpretation of imagination in the process of knowing, since his theory of the former as one of the internal senses became canonical for the later Latin thinkers.

Indeed, it is likely that at the beginning of that century Avicenna was better known and more influential in the Occident than was Aristotle. In so doing, Avicenna contributed new doctrines and theories that were to shape the later medieval and Renaissance conceptions of the soul and its cognitive powers.

In his De anima, Avicenna identified five internal senses. They were translated into Latin under the names 1 fantasia or sensus communis, 2 imaginatio, 3 vis aestimationis, 4 vis memorialis or reminiscibilis, and 5 vis imaginativa or cogitans. Avicenna's De anima was translated into Latin in the twelfth century by Gundissalinus. The Latin tradition quickly abandoned the terminological identification of 'phantasia' with 'sensus communis' found in the translation of Avicenna.

The Latin terminology, at any rate, varied greatly from author to author. Charles B. These forms are stored for future use in the imagination, a kind of sense-image memory.
