Osaka

I’ll be giving a series of lectures at the Deleuze Camp (Workshop) in Osaka at the end of May. Here are the abstracts of the lectures. Any comments or feedback are welcome.

“Learning to Think: Deleuze and the Art of Philosophy”

Lecture 1: The Problem with Solutions

In this first of three lectures I will begin to defend what I take to be Deleuze’s metephysics of multiplicity, a metaphysics that combines both an affirmation of Humean multiplicity and a Spinozist affirmation of monism. A guiding theme in these lectures will be Hume’s theory of taste, as found in his essay “Of the Standard of Taste.” This theme is not arbitrary, for in Chapter 3 of What is Philosophy?, Deleuze and Guattari argue that it is taste that is the “philosophical faculty of coadaptation” that  relates the three elements that “constitute the philosophical trinity”—namely, the plane of immanence, conceptual personae, and concepts. This lecture will take up the theme of problems and argue that what is distinctive about philosophy is that it has a taste for the problems that are immanent to the solutions that supposedly resolve and displace them.

Lecture 2: Where there’s a will, there’s a way

In this lecture I will revisit the problem that Deleuze takes to be central to Hume’s philosophical project—that is, the problem of how a “subject transcending the given [can] be constituted in the given.” For Hume this was the problem of accounting for how one comes to the belief that A causes B when there is nothing in A, nor in the succession of A and B, that necessitates the causal relationship between A and B. For Deleuze this emerges as the problem of accounting for how an identity that is irreducible to difference is nonetheless constituted in difference. In short, how does difference-in-itself serve as the principle of sufficient reason for any and all individuated identities. The concept of conceptual personae, we will see, needs to be understood in the context of Deleuze’s efforts to respond to this problem.

Lecture 3: Learning to Think

The focus of the final lecture will be Deleuze’s claim, in Difference and Repetition, that “to think is to create – there is no other creation—but to create is first of all to engender ‘thinking’ within thought.” (DR 147) The first two lectures will have begun to lay out the conditions necessary for engendering thinking in thought. In this lecture we will look further at the relationship between thought and thinking. Learning to think, I will argue, entails a taste for the problems within thought itself, and both Hume and Deleuze had a taste for such problems; or, both were adept at learning to think.

Facebook Friends

In his second letter to Lucilius (discussed here), Seneca encourages him to linger over the texts of “master-thinkers” and “select one [thought] to be thoroughly digested that day.” (Letter 2). We are to befriend thought rather than be merely an acquaintance of thought. Yet the question arose as to how best to determine which thoughts to befriend. How do we select our thought for the day? In Letter 3 we begin to get an answer to this question when Seneca challenges Lucilius for his use of the term “friend.” When Lucillius had a friend – “as you call him” Seneca adds – deliver a letter to Seneca, Lucilius goes on in the next sentence to warn Seneca “not to discuss with him all the matters that concern you, saying that even you yourself are not accustomed to do this.” Seneca’s conclusion: “in the same letter [you have] affirmed and denied that he is your friend.” A true friend is one with whom we share everything. As Seneca puts it, “I would have you discuss everything with a friend; but first of all discuss the man [friend; jb] himself” (ipso prius).

Befriending Thought

If the lesson of Seneca’s first letter to Lucilius is to recognize, in light of the fact that we are “dying daily,” that our time is precious (see this post), the second letter cautions Lucilius to avoid what is no doubt a likely consequence of this recognition: namely, the conclusion that we ought to hurry up and live intensely and in haste for there is precious little time. This is the opposite of how we are to live if we are to live to our “purpose” (Letter 1). For Seneca to live in such haste, to hurry about from place to place, person to person, and book to book, “is the sign of a disordered spirit.” The key is for one to “remain in one place and linger in one’s own company,” be content with a few friends, and read just a “limited number of master-thinkers.” Hurrying about from place to place, person to person, text to text, may give one a vast number of acquaintances but no friends, and yet if we are to live to our purpose and fulfill “today’s task” (Letter 1), we will become a friend to ourselves, persons, and texts. In short, and most importantly, we will become a friend to thought.

Seneca and the Condemned Prisoner

To begin with Seneca and take on board the problems that motivated his philosophical writings, we can start with the concluding paragraph of his first letter to Lucilius. The paragraph begins with the question: “What is the state of things, then?” to which Seneca answers that we are not to “regard a man as poor, if the little which remains is enough for him,” and then he directly advises Lucilius “to keep what is really yours.” The problem then for Seneca is a problem of loss, and of keeping and having enough, and that which can and is most frequently lost and which we seem never to have enough of, and yet which is most ours, is time. “Nothing, Lucilius,” Seneca urges, “is ours, except time.” This problem, however, is a substantial problem, a problem of substance and being (ousia), and connected to this problem is a relationship to time, to that which belongs to us more than anything else, and yet it is time that is least appreciated and most frequently lost. Thus the subject of Seneca’s first letter is to caution Lucilius to be wary of the ease with which we lose time, and hence lose ourselves.

“fourfold root” of representation

Since much of the impetus for Deleuze’s approach to the PSR stems from a critique of representation, I thought it would be good to post a quick summary of this critique. In short, Deleuze argues that for representational modes of thought difference is always mediated by an already presupposed identity, when it is precisely the conditions for the possibility of identity itself that most concerns Deleuze. The mediation of representation by identity occurs in four ways, what Deleuze calls the “fourfold root” (see DR 29): namely, identity, analogy, opposition, and resemblance.

Strange Encounters II

As I concluded the previous post, I argued that the Deleuzian extension of Hume’s project entailed both the affirmation of monism (Spinoza) and multiplicity (Hume). This point is made crystal clear in A Thousand Plateaus when Deleuze and Guattari announce that “pluralism = monism” (ATP, p. 2; see this earlier post where I discuss this theme in the context of William James’ radical empiricism). This effort to bring Hume and Spinoza together, however, is fraught with difficulty, or at least apparently so, in a philosophical landscape that has been forever altered by Kant’s project. Since Kant was woken from his dogmatic slumber, Hume and Spinoza have come to be rethought, if rethought at all, in the context of the conditions for the possibility of experience. In the case of Hume, this has largely led his philosophy to be read as a project in epistemology. Hume comes to be seen as a precursor of a Bayesian epistemology whereby knowledge comes to be constituted through a process of induction that constitutes degrees of belief. Spinoza, at worst, is thrown into the refuse pile of philosophical dogmatists, one of the philosophers who accepted, without question, that guarantees of our knowledge. Spinoza, in fact, goes much further than either Descartes and Leibniz in that while they accept God as the unquestioned guarantor of our knowledge of the world (Descartes) as well as the harmony of the world itself (Leibniz), God remains inaccessible and unknowable; Spinoza, by contrast, argues in the last half of Part 5 of the Ethics that even God can be known.

To state the contrast between Spinoza the dogmatist and Hume the skeptic, one could say that Spinoza presupposes the identity that grounds knowledge while Hume argues that this identity comes to be constituted. Husserl remarked upon this aspect of Hume’s thought, and it is for this reason that I have argued for a Humean phenomenology (see this). So how then can one bring Hume and Spinoza together? Put simply, through a rethinking of the principle of sufficient reason (PSR). And this brings me back to the issue that in part spawned the New Hume debate – to wit, Hume’s claim that the “particular powers, by which all natural operations are performed” are powers that provide the reason for the regularities of nature but these powers “never appear to the senses.” What are these powers? The simple answer to this question is that these are the laws of nature that are the subject of natural science, and it is precisely the nature of these powers that are revealed, over time, through the process of scientific enquiry. We could say that this is a scientific explanation of facts. That which appears to the senses, therefore, would bring in our mental faculties and the epistemological problems of how we come to know the “particular powers” of nature. With this we have an epistemological explanation, and form here we are not too far from the Bayesian epistemology mentioned above.

Strange Encounters

One of my favorite passages from Hume actually occurs twice – in the Treatise and the Enquiry. This is the passage where Hume offers up the example of the man with normally functioning faculties who is suddenly placed into a strange, unfamiliar environment. This is the lesson Hume draws from this thought experiment:

For ‘tis evident, that if a person full-grown, and of the same nature with ourselves, were on a sudden transported into our world, he wou’d be very much embarrass’d with every object, and would not readily find what degree of love or hatred, pride or humility, or any other passion he ought to attribute to it. The passions are often vary’d by very inconsiderable principles; and these do not always play with a perfect regularity, especially on the first trial. But as custom and practice have brought to light all these principles, and have settled the just value of every thing; this must certainly contribute to the easy production of the passions, and guide us, by means of general establish’d maxims, in the proportions we ought to observe in preferring one object to another. (T 2.1.6, 293-4)

In the Enquiry Hume slightly modifies the example:

Suppose a person, though endowed with the strongest faculties of reason and reflection, to be brought on a sudden into this world; he would, indeed, immediately observe a continual succession of objects, and one event following another, but he would not be able to discover any thing farther. He would not, at first, by any reasoning, be able to reach the idea of cause and effect; since the particular powers, by which all natural operations are performed, never appear to the senses; nor is it reasonable to conclude, merely because one event, in one instance, precedes another, that therefore the one is the cause, the other the effect. Their conjunction may be arbitrary and casual. There may be no reason to infer the existence of one from the appearance of the other. And in a word, such a person, without more experience, could never employ his conjecture or reasoning concerning any matter of fact, or be assured of any thing beyond what was immediately present to his memory and senses. (EHU 36).

Back from NewAPPS

After a good couple of years posting at NewAPPS, although less and less frequently of late, I’ve decided to return to my own blog as the site where I’ll put up some of the ideas and concepts I’m working on, opening them up for discussion and hopefully helpful feedback. Although I’ve greatly enjoyed being associated with NewAPPS – NewAPPS has done and will continue to do great things to help improve the philosophy profession – it is no longer the appropriate place for me to have the freedom to put forth the tentative, experimental thoughts and ideas that I find myself working on at the moment. As a result I’ll now be posting here on a more regular basis and I welcome whatever comments anyone might have.

What I’m working on at the moment, and what one might expect to see in the way of posts in the short term, is a Deleuzian metaphysics of problems. I’ve just given a few talks in Australia on this subject and will churn out a few posts drawn from these talks. In short, I’ll be attempting to lay out the metaphysical presuppositions that were at play in my Deleuze’s Hume book, especially as this book draws upon the concept of historical ontology. This concept, I must admit, was not as fully developed as it could have been, and this largely because I needed to come to grips with the metaphysics this concept presupposes. I was concerned with other problems in Deleuze’s Hume and historical ontology, along with Latour’s notion of “relative existence,” helped me to address and respond to them. It’s now time to focus on the metaphysics historical ontology entails, and that’s what I’ll be up to now. I’ll also probably write some posts on Seneca, Nagarjuna, and other writers I’ve long had an interest in and whose thought I’d like to clarify for myself without the need to produce a perfect, publishable piece. I may be following in the footsteps of Eric Schliesser’s Seneca posts as I venture down that path, but that’s neither a bad path nor are those bad footsteps to follow.

Degrees of Difference and Working Façades


Dessin-Caduveo-5
This is cross-posted from NewAPPS (where I’ve been posting for a while, though I may begin posting more here)

John’s nice post has reminded me of the importance of repetitive series for Deleuze (an issue I also discuss here). Picking up on John’s discussion of the perception of colors, series play an important role in attempting to accounting for our use of predicates: in short, Deleuze will often place predicates within the context of a series of predicates – e.g., shades of blue. This pattern is most obvious in Deleuze’s Logic of Sense, where each chapter is titled “First Series of…” “Second Series of…” etc.… But why series?

Two short answers, which I’ll expand on below the fold: 1) a series of differences is precisely what provides, in good Spinozist fashion, the principle of sufficient reason for determinate phenomena; and 2) series in turn provide the metaphysics science needs.

Let us take a simple series of phenomena, E, E, E, E, etc. … Let us also assume there is no difference between the elements of the series. For Deleuze, however, each element, as an identifiable, determinate phenomenon, refers “to an inequality by which it is conditioned.” (DR 222). Thus every extrinsically distinct element presupposes an intensive difference, what Deleuze will call an “intensive quantum” (DI 88), and thus in the series E, E, E, E …, E itself presupposes the intensive quantum e-e’, and the element e presupposes ε-ε’, and so on ad infinitum. Deleuze will call this “state of infinitely doubled difference which resonates to infinity disparity,” which he then adds is “the sufficient reason of all phenomena, the condition of that which appears.” (DR 222; emphasis mine). One can picture this “state of infinitely doubled difference” by way of the graphs of Feigenbaum’s constant where functions approach chaos through period doubling:

FeigenbaumConstantBifurcation_1000

Returning to the use of predicates, this difference or disparity that is the “sufficient reason of all phenomena” does not inhere in phenomena as their predicate, nor even as a separate or separable element, but it is rather the particularity of each element taken to the limit, or what Deleuze will call a “concrete universal.” For example, if we take a series of colors such as the several shades of blue one might find on a paint sample card at a hardware store, our tendency is indeed to consider each of these individual colors as a “shade of blue.” In other words, each particular color is differentiated from one another by a matter of degrees from one general color, blue, with these degrees running the spectrum from high to low saturation. Deleuze, however, argues that this is wrong. Following through on Bergson’s discussion of Revaisson (see DI 43), the universal is not an abstract concept distinct from each particular shade of blue, in which case we have an external difference, or a difference between the shades made possible by virtue of a universal that is external to them and of which they are varying degrees or shades. To the contrary, the concrete universal is the infinitely doubled difference that resonates and inheres within each appearing shade. In the case of a particular shade of blue, this concrete universal is “white light,” or it is the infinitely doubled difference (the far right of the above graph) that “makes the difference come out between the shades”; or,

…the different colors are no longer objects under a concept, but nuances or degrees of the concept itself. Degrees of difference itself, and not differences of degree. White light is still a universal, but a concrete universal, which gives us an understanding of the particular because it is the far end of the particular… (DI 43)

One can find further evidence for Deleuze’s metaphysics in Mark Wilson’s essay “Theory Façades,” (which can be gotten here) and in his subsequent book Wandering Significance. Wilson provides numerous examples, and with dizzying detail, to argue that throughout “scientific work” one finds that what is put to work in the effort to provide theoretical directives are “sheets of doctrine that do not truly cohere into unified doctrine in their own rights, but can merely appear as if they do if the qualities of their adjoining edges are not scrutinized scrupulously.” (“TF” p. 273) What may work well at one level and scale may begin to fail at a more detailed and enhanced level of description. As Wilson puts this in Wandering Significance,

…as our everyday descriptive terms become pressed to higher standards of accuracy or performance, as commonly occurs within industry or science, a finer and more perplexing grain of conflicting opinion begins to display itself within our applications of “hardness,” “force” and even “red.” (p. 7)

Put in the Deleuzian terms discussed above, the effort to produce accurate descriptions of phenomena encounters, with the increasing demands of more detailed and nuanced analysis, the substantive multiplicity or concrete universal that is the sufficient reason for the phenomena being described. The result is the failure of descriptive terms as these terms get pushed towards increasing particularity of detail; in short, as they are pushed toward the concrete universal that is “the far end of the particular.” (DI 43). What happens, Wilson argues, in our attempts to maintain “inferential headway” in the face of the difficulties that arise as the level of particularity increases, is that we often find it easier “to decompose the system’s overall behavior into descriptive fragments where the intractable complexities of the full problem become locally reduced to more tractable terms.” (TF pp. 273-4). Wilson offers the example of what happens when we attempt to use applied mathematics to understand the formation of spray on “the surface of a choppy ocean.” (WS p. 210, as are subsequent quotes). If the ocean is modeled as a continuous fluid, the partial differential equations will provide accurate descriptions to a point, but then it fails to track the phenomena for the equations continue “to plot an attached blob that never relinquishes its absurdly elongated umbilical tie to the mother ocean.” To offset this poor description, one solution is to run the model with an already detached blob that then separates from the ocean. This provides for a good description where the continuous model does not, but then the description is poor where the continuous model’s was good. If we combine the two models together, we can overlap them such that it provides a good description for the entire process. While this may be effective at providing an accurate description, Wilson argues that what is going on here is an exercise in “physics avoidance in that we do not directly describe the molecular processes that lead to drop separation, but merely cover the relevant region with an interpolating patch.” In other words, there is a repressed difference or boundary between the two patches that is then mistakenly held to be a unified account of water separation when it is not. Wilson is not arguing that no account of the water separation is possible. His argument is that an adequate account of the boundary where the different patches converge may well entail a complex mathematics beyond our ken at this point. As a result, and due largely to impatience, we are often tempted, Wilson claims, “to pretend as if our façade patchwork provides a wholly adequate descriptive framework solely on its own terms…” (TF 275)

Wilson’s point, however, and this is just what one would expect given the Deleuzian metaphysics and its use of the PSR, is that however detailed and nuanced the theoretical and mathematical description might be, there are underlying differences that subvert them as the level of description pushes to the “far end of the particular.” In other words, substantive multiplicity (or concrete universal) may be the sufficient reason for every phenomena, but it is also the reason our mathematical equations and theories which track phenomena will forever flirt with, and be challenged by the intensive differences that fail to be explicated and hence modeled by their equations. Wilson makes a very similar point in the early pages of Wandering Significance, and one quite in line with reading of Deleuze’s metaphysics offered here. Wilson argues that,

The main consideration that drives the argument of the book is the thesis that the often quirky behaviors of ordinary descriptive predicates derive, not merely from controllable human inattention or carelesseness, but from a basic unwillingness of the physical universe to sit still while we frame its descriptive picture. (WS 11)
