Yesterday, I noted that one way to understand Hume's significance to our conceptualization of causation is two-fold: first, that he whittled down four Aristotelian causes to just one kind of cause (previously known as 'efficient causation'); and, second, that he is the source of the modern conception of causation by offering a counterfactual definition of it in the first Enquiry. Hume is also taken to be the source of our modern discussion of convention, (recall here) although a very good argument can be made that Hume is greatly indebted to Locke (see also this more recent post and this one as a follow up). In today's post I suggest that Hume's account of convention itself is greatly indebted to the Aristotelian causes. Let me explain by first re-quoting a familiar passage from Hume:
But if by convention be meant a sense of common interest; which sense each man feels in his own breast, which he remarks in his fellows, and which carries him, in concurrence with others, into a general plan or system of actions, which tends to public utility; it must be owned, that, in this sense, justice arises from human conventions. For if it be allowed (what is, indeed, evident) that the particular consequences of a particular act of justice may be hurtful to the public as well as to individuals; it follows, that every man, in embracing that virtue, must have an eye to the whole plan or system, and must expect the concurrence of his fellows in the same conduct and behaviour. Did all his views terminate in the consequences of each act of his own, his benevolence and humanity, as well as his self-love, might often prescribe to him measures of conduct very different from those, which are agreeable to the strict rules of right and justice.
In the posts linked above I argued that Hume's analysis of convention has eight parts (most also to be found in Locke's Second Treatise and the Essay):
I call I-VIII: ‘the Humean template,’ and they are jointly sufficient, although (VII) is not necessary.
Now, the Humean template has quite a few moving parts. And given that in Locke the Humean template is used but, as far I am aware, not explicitly analyzed it's worth asking to what degree he would have been fully conscious of the Humean template. It's always a risk with the kind of structuralist analysis I offer here that it is merely a projection of the historian onto an earlier text. Even if that were so it can still be illuminating, of course, but to use the 'Humean template' about Locke would be straightforward anachronism (albeit useful anachronism).
But even though Locke does not explicitly analyze the Humean template, i don't think it's a mere projection on my part for three reasons (the first two of which outlined in the linked posts): first, as I realized by reflecting on work by Martin Lenz (Socializing Minds) Locke is clearly responding to lacunae in Puffendorf's account of the origin and stability of conventions. Second, the Humean template can be found in the second Treatise and the Essay (and is evoked later in the Essay). These two reasons are internal to Locke's project.
In addition, third, we can discern the portfolio of Aristotle's four causes in the Humean template. For, (VI) is the final cause(s) of a convention. And (I) is the formal cause. In addition, (II-V) are the efficient and material causes of the convention. I mix these causes here because jointly they tie the formal and final cause together in the workings of the convention.
If Locke's use of the Humean template presupposes the Aristotelian causes then it's also no surprise that he doesn't need to offer an explicit analysis of the Humean template. His readers would have noticed it without his saying so. In Hume, the template is made explicit precisely because a reader familiar with Hume's philosophy cannot take for granted that Hume would draw on the non-efficient Aristotelian causes.
That (VI) is a final cause strikes me as uncontroversial. But it is surprising to find it in Hume, who is really an explicit and implicit critic of final causes (see here also for references). Of course, in virtue of providing the mechanism for its functionality one may well say that the Humean template naturalizes or presupposes a naturalized teleology. One may also claim that in human affairs, a certain kind of intentionality and goal directed is inelimenable.
The real question here is to what degree the common interest that a tacit convention secures is fully foreseaable and articulable ahead of time. For example, Adam Smith famously criticized the deployment of the Humean template in Hume's account of the origin of justice in circumstances that echo a state of nature because Hume's account seems to presuppose awareness of the final cause, or at least assume common interest, in a context where this sense of unity or mutual loyalty, seems unlikely. (See here for the full story.)
The passage at the top of the post is near the conclusion of Smith's diagnosis of the error in Hume. Interestingly enough, in Part II of the Elements of the Philosophy of the Human Mind, Dugald Stewart notes Smith's criticism of Hume, and quotes the passage in order to illustrate "a common error," which Stewart associates with the "dangerous" revitalisation of utilitarianism (he explicitly discusses Paley and Godwin in context). Stewart praises Adam Smith because "he always treats separately of their final causes, and of the mechanism, as he calls it, by which nature accomplishes the effect; and he has even been at pains to point out to his successors the great importance."
To be sure, Smith's criticism does not touch all instances of Hume's use of the Humean template. For, in some contexts the common interest is knowable even known and the efficient and material causes of the Humean template can do their work without presupposing that all the benefits from the convention are presupposed in the mechanism that gives rise to the convention or that these benefits are or would have to be obscure to the agents involved.
This problem does not even arise in Locke. For, of course, the natural reading of much of Locke's writings is that he embraces a God given providential order. (But recall this post for the debate.) So, in Locke the use of the Humean template is completely natural and without a blemish of inconsistency.*
* I am not denying that Aristotelian formal and material causes get reinterpreted in Locke. I am grateful to discussion with Susan James, Martin Lenz, Charles Wolfe, Spiros Tegos, Katarina Peixoto and others in Budapest.
Perhaps eventually an overall Big Picture will emerge—and perhaps not: Hegel thought that the Owl of Minerva would take wing only at dusk (i.e., that we will only achieve understanding in retrospect, after it’s all over), but maybe the Owl’s wings have been broken by hyperspecialization, and it will never take to the air at all. What we can reasonably anticipate in the short term is a patchwork of inference management techniques, along with intellectual devices constructed to support them. One final observation: in the Introduction, I gave a number of reasons for thinking that our response to the Great Endarkenment is something that we can start working on now, but that it would be a mistake at this point to try to produce a magic bullet meant to fix its problems. That turns out to be correct for yet a further reason. Because the approach has to be bottom-up and piecemeal, at present we have to suffice with characterizing the problem and with taking first steps; we couldn’t possibly be in a position to know what the right answers are.
Thus far our institutional manifesto. Analytic philosophy has bequeathed to us a set of highly refined skills. The analytic tradition is visibly at the end of its run. But those skills can now be redirected and put in the service of a new philosophical agenda. In order for this to take place, we will have to reshape our philosophical pedagogy—and, very importantly, the institutions that currently have such a distorting effect on the work of the philosophers who live inside them. However, as many observers have noticed, academia is on the verge of a period of great institutional fluidity, and flux of this kind is an opportunity to introduce new procedures and incentives. We had better take full advantage of it.--Elijah Millgram (2015) The Great Endarkenment: Philosophy for an Age of Hyperspecialization, p. 281
There is a kind of relentless contrarian that is very smart, has voracious reading habits, is funny, and ends up in race science and eugenics. You are familiar with the type. Luckily, analytic philosophy also generates different contrarians about its own methods and projects that try to develop more promising (new) paths than these. Contemporary classics in this latter genre are Michael Della Rocca's (2020) The Parmenidean Ascent, Nathan Ballantyne's (2019) Knowing Our Limits, and Elijah Millgram's (2015) The Great Endarkenment all published with Oxford. In the service of a new or start (sometimes presented as a recovery of older wisdom), each engages with analytic philosophy's self-conception(s), its predominate methods (Della Rocca goes after reflective equilibrium, Millgram after semantic analysis, Ballantyne after the supplements the method of counter example), and the garden paths and epicycles we've been following. Feel free to add your own suggestions to this genre.
Millgram and Ballantyne both treat the cognitive division of labor as a challenge to how analytic philosophy is done with Ballantyne opting for extension from what we have and Millgram opting for (partially) starting anew (about which more below). I don't think I have noticed any mutual citations. Ballantyne, Millgram, and Della Rocca really end up in distinct even opposing places. So, this genre will not be a school.
Millgram's book, which is the one that prompted this post, also belongs to the small category of works that one might call 'Darwinian Aristotelianism,' that is, a form of scientific naturalism that takes teleological causes of a sort rather seriously within a broadly Darwinian approach. Other books in this genre are Dennett's From Bacteria to Bach and Back (which analyzes it in terms of reasons without a reasoner), and David Haig's From Darwin to Derrida (which relies heavily on the type/token distinction in order to treat historical types as final causes). The latter written by an evolutionary theorist.* There is almost no mutual citation in these works (in fact, Millgram himself is rather fond of self-citation despite reading widely). C. Thi Nguyen's (2020) Games: Agency as Art may also be thought to fit this genre, but Millgram is part of his scaffolding, and Nguyen screens off his arguments from philosophical anthropology and so leave it aside here.
I had glanced at Millgram's book when I wrote my piece on synthetic philosophy, but after realizing that his approach to the advanced cognitive division of labor was orthogonal to my own set it aside then.++ But after noticing intriguing citations to it in works by C. Thi Nguyen and Neil Levy, I decided to read it anyway. The Great Endarkenment is a maddening book because the first few chapters and the afterward are highly programmatic and accessible, while the bulk of the essays involve ambitious, revisionary papers in meta-ethics, metaphysics, and (fundementally) moral psychology (or practical agency if that is a term). The book also has rather deep discussions of David Lewis, Mill, and Bernard Williams. The parts fit together, but only if you look at them in a certain way, and only if you paid attention in all the graduate seminars you attended.
Millgram's main claim in philosophical anthropology is that rather than being a rational animal, mankind is a serial hyperspecializing animal or at least in principle capable of hyperspecializing serially (switching among different specialized niches it partially constructs itself). The very advanced cognitive division of labor we find ourselves in is, thus, not intrinsically at odds with our nature but actually an expression of it (even if Millgram can allow that it is an effect of economic or technological developments, etc.). If you are in a rush you can skip the next two asides (well at least the first).
As an aside, first, lurking in Millgram's program there is, thus, a fundamental critique of the Evolutionary Psychology program that takes our nature as adapted to and relatively fixed by niches back in the distant ancestral past. I don't mean to suggest Evolutionary Psychology is incompatible with Millgram's project, but it's fundamental style of argument in its more prominent popularizations is.
Second, and this aside is rather important to my own projects, Millgram's philosophical anthropology is part of the account of human nature that liberals have been searching for. And, in fact, as the quoted passages reveal, Millgram's sensibility is liberal in more ways, including his cautious preference for "bottom-up and piecemeal" efforts to tackle the challenge of the Great Endarkenment.+
Be that as it may, the cognitive division of labor and hyperspecialization is also a source of trouble. Specialists in different fields are increasingly unable to understand and thus evaluate the quality of each other's work including within disciplines. As Millgram notes this problem has become endemic within the institution most qualified to do so -- the university -- and as hyper-specialized technologies and expertise spread through the economy and society. This is also why society's certified generalists -- journalists, civil servants, and legal professionals -- so often look completely out of their depth when they have to tackle your expertise under time pressure.** It's his diagnosis of this state of affairs that has attracted, I think, most scholarly notice (but that may be a selection effect on my part by my engagement with Levy's Bad Beliefs and Nguyen's Games). Crucially, hyperspecialiation also involves the development of languages and epistemic practices that are often mutually unintelligible and perhaps even metaphysically incompatible seeming.
As an aside that is really an important extension of Millgram's argument: because the book was written just before the great breakthroughs in machine learning were becoming known and felt, the most obvious version of the challenge (even danger) he is pointing to is not really discussed in the book: increasingly we lack access to the inner workings of the machines we rely on (at least in real time), and so there is a non-trivial sense in which if he is right the challenge posed by Great Endarkenment is accelerating. (See here for an framework developed with Federica Russo and Jean Wagemans to analyze and handle that problem.)
That is, if Millgram is right MacAskill and his friends who worry about the dangers of AGI taking things over for rule and perhaps our destruction by the machine(s) have it backwards. The odds are more likely that our society will implode and disperse -- like the tower of Babel that frames Millgram's analysis -- by itself. And that if it survives mutual coordination by AGIs will be just as hampered by the Great Endarkenment, perhaps even more so due to their path dependencies, as ours is.
I wanted to explore the significance of this to professional philosophy (and also hint more at the riches of the book), but the post is long enough and I could stop here. So, I will return to that in the future. Let me close with an observation. As Millgram notes, in the sciences mutual unintelligibility is common. And the way it is often handled is really two-fold: first, as Peter Galison has argued, and Millgram notes, the disciplines develop local pidgins in what Galison calls their 'trading zones.' This births the possibility of mutually partially overlapping areas of expertise in (as Michael Polanyi noted) the republic of science. Millgram is alert to this for he treats a lot of the areas that have been subject of recent efforts at semantic analysis by philosophers (knowledge, counterfactuals, normativity) as (to simplify) really tracking and trailing the alethic certification of past pidgins. Part of Millgram's own project is to diagnose the function of such certification, but also help design new cognitive machinery to facilitate mutual intelligibility. That's exciting! This I hope to explore in the future.
Second, as I have emphasized in my work on synthetic philosophy, there are reasonably general theories and topic neutralish (mathematical and experimental) techniques that transcend disciplines (Bayesianism, game theory, darwinism, actor-network, etc.). On the latter (the techniques) these often necessetate local pidgins or, when possible, textbook treatments. On the former, while these general theories are always applied differently locally, they are also conduits for mutual intelligibility. (Millgram ignores this in part.) As Millgram notes, philosophers can make themselves useful here by getting MAs in other disciplines and so facilitate mutual communication as they already do. That is to say, and this is a criticism, while there is a simultaneous advancement in the cognitive division of labor that deepens mutual barriers to intelligibility, some of this advance generates possibilities of arbitrage (I owe the insight to Liam Kofi Bright) that also accrue to specialists that help transcend local mutual intelligibility.** So, what he takes to be a call to arms is already under way. So, let's grant we're on a precipice, but the path out is already marked.
*Because of this Millgram is able to use the insights of the tradition of neo-thomism within analytic philosophy to his own ends without seeming to be an Anscombe groupie or hinting darkly that we must return to the path of philosophical righteousness.
+This liberal resonance is not wholly accidental; there are informed references to and discussions of Hayek.
** Spare a thought for humble bloggers, by the way.
++UPDATE: As Justin Weinberg reminded me, Millgram did a series of five guest posts at DailyNous on themes from his book (here are the first, second, third, fourth, and fifth entries.) I surely read these, and encourage you to read them if you want the pidgin version of his book.
