An Ethical Argument for Philosophy Co-Authorship; on Friendship and Disagreement

This piece was co-written and co-published with Eric Schliesser.

The most dazzling example of co-authorship is Paul Erdős, who co-wrote more than 1400 papers in mathematics with 485 collaborators. (What is your Erdős number?) To do this, he became functionally homeless: “His modus operandi was to show up on the doorstep of a fellow mathematician, declare, “My brain is open,” work with his host for a day or two, until he was bored or his host was run down, and then move on to another home.”

In the sciences, co-authorship is normal. In the humanities, it is uncommon. In philosophy, it is almost non-existent. (See chart.)[1] Yet philosophy is not without famous co-authors (e.g., Marx and Engels). What’s more, some monographs ought properly be considered co-authored, like John Stuart Mill’s collaborations with Harriet Taylor Mill: “when two persons have their thoughts and speculations completely in common it is of little consequence, in respect of the question of originality, which of them holds the pen.”

There is little scholarship on co-authorship in philosophy, but a steady trickle of blog posts suggests that there is interest and anxiety on this point. (Helen de Cruz, Mark Zelcer, Robert Paul Wolff)

1.      What is co-authorship generally?

Co-authorship in the sciences is ideally ruled by two rules rooted in a particular sociology of labs and research groups. First, co-authors contribute to the scholarly endeavor for a piece of publishable scholarship by planning, executing, or analyzing the results of some sort of research. Second, co-authors compose the written portion of the research, either collectively or through some division of labor.

Both of these ideals are violated, of course—there are plenty of massive multi-authored articles where scholars receive token authorship (gift authorship) or someone who made substantial contributions is not credited as an author (ghost authorship.) In that way, these are “endorsed” norms, not the “enforced” ones: violations abound and are even legitimated as common practice in some “big science” research areas. But this remains the practical ideal.

2.      Why is co-authorship deprecated in philosophy?

Professional philosophers collaborate, usually through disputatious conversation, but usually not in a way that counts multiple thinkers as the author of a single paper. We are also much less likely to cite our peers than the agenda-setting papers in our sub-fields, especially as a part of a generic literature review. (See Kieran Healey’s data.) It is more common for close collaborators to co-edit than to co-author: for instance, Amartya Sen and Martha Nussbaum famously created the “capabilities approach” together without co-authoring any of their foundational papers. They did, however, co-edit the seminal volume, The Quality of Life in 1993.

So while we do not imagine ourselves to be lone geniuses communing with the ancient canon, it is the case that many philosophical papers are projected as manifestos of a single principled thinker. Indeed, philosophers are particularly prone to a kind of “subauthorial collaboration” that is formalized in lavish acknowledgements in the text or an early footnote. (Cronin, Shaw, La Barre, 2003)

David Lewis, who understood philosophical politics as well as anybody (recall),  comments on this kind of “ghost” authorship in his paper, “Causation as Influence:”:

“This paper mostly presents the latest lessons I’ve learned from my students. Under the customs of the natural sciences, it should have been a joint paper, the coauthors being (in alphabetical order) John Collins, Ned Hall, myself [David Lewis], L.A. Paul, and Jonathan Schaffer. But under the customs of philosophy, a paper is expected to be not only a report of discoveries but a manifesto; and, happily, the five of us have by no means agreed upon a common party line.”[2]

Yet analytic philosophers often imagine themselves by analogy to the natural and social sciences, and American and continental philosophers increasingly emphasize the collaborative nature of our enterprise. Why, then, do we not use co-authorship more?

One obvious reason is the relative paucity of grants and research support compared to the natural and social sciences. Without an incentive to adopt the lab or research group model, most working philosophers are not members of a funded research unit with reporting requirements. Rigorous research is understood to support ‘research-led teaching,’ and so the single-author model is based primarily on the single-teacher model. We should thus expect the introduction of larger private grant-making institutions, like the Templeton Foundation and the Berggruen Institute, and public European grant agencies, to usher in an era of increasing research group size in philosophy, and the more frequent co-authorship.

We expect that  new collaborative technologies will decrease the costs and difficulties of collaboration to the extent that philosophers will more often overcome them, even without any increased funding or benefits. Google Docs, Dropbox Paper, and simple Microsoft Office sharing, versioning, and commenting will all tend to ease the speed with which scholars of all varieties—including philosophers—create collaborative documents. Social media, chat programs, and email ease collaboration over distance to replicate the proximity by which labs and research groups co-compose.

Lastly, we might think of philosophical research as long-shot bets (Langhe and Schliesser, 2017) that explore concepts, methods, or techniques that may be generally applicable. As such, it will be difficult to trace any particular result in the world back to a paper or monograph, and it is preferable to have many such long-shot bets rather than focus the efforts and attention of a highly skilled research team on sequential elaboration of just one of these gambles. It will generally be better to encourage idiosyncratic work done by individuals and small teams in hopes that one of those bets pays off. In the age of increasingly easy collaboration some enduring, virtual small research teams will emerge without, hopefully, fully displacing lone wolfs and disputatious research groups.

3.     What norms of co-authorship might philosophers embrace?

If philosophers do adopt co-authorship norms, which ones should we adopt?

We should start with the ideal of recognition of actual contribution to the research and knowing participation in the composition. Co-authorship should never be merely “honorary” inclusion for a member of a team or department who contributed to neither the research work nor the writing endeavor. However, the division of labor in some disciplines has the result of producing co-authored pieces where some credited contributors don’t even understand the paper they have helped to produce. Should we extend co-authorship to a student assistant who writes the literature review for a piece of research without understanding the rest of the paper? Should we accept co-authorship for a paper whose conclusions we do not endorse, if we supplied the formal modeling or computer code that underwrites it?

Our current professional ideal is consensus. On this ideal all authors must give credence to every jot and tittle of the work, even if their confidence varies slightly. Co-authorship in philosophy is stricter because philosophers can and should endorse all the claims, arguments, and conclusions of the paper. Papers can be thus be co-authored in philosophy when two or more researchers find a common interest, discuss it at great length, and truly co-compose the entire paper, contesting each argumentative move and turn of phrase until agreement is reached. As such, it should be very unlikely to see large groups of co-authors writing together, given the difficulty of producing such an exacting meeting of the minds, and we even look askance at philosophy papers co-authored by three or four scholars.

Another possibility is that philosophers working on closely-related research might try to divvy up the tasks in a field of research around some question such that only one or a few of the authors of a work understand the whole thing, while others are credited for their contributions without being “first” or “lead” author status. This requires trust in each other to handle sections of the paper that address relevant issues from their sub-fields; perhaps a paper that is 12,000 words long is written in two halves, with only the introduction and conclusion truly a joint project. On this ideal, co-authors retain to right to veto truly abhorrent claims made outside of their assigned sections, but only by threatening to dissolve the partnership. Otherwise, they can only register objections and hope to be heard.

A third possibility would be to follow the norm in law courts, where empaneled and en banc judges issue both dissenting opinions or in some cases join the majority in parts of their decision but not others, perhaps affirming the result but not all of the methods used to arrive at it. In such cases, a minority might dissent vehemently, while the court is understood to have rendered the opposite verdict: that minority dissent is clearly a separate research project in philosophical terms. They are not understood as co-authors of the majority opinion but as co-authors of a distinct opinion which did not win a majority of support. The more instructive question is what to do when judges affirm parts of the main decision but not all of it, and by analogy, situations where co-authors affirm parts of a research project but not all of it. Can it be possible for one of the co-authors to “sign on” to parts 1, 2, and 4 of a paper, while dissenting from arguments found in part 3 and in the conclusion? For example, in the past one of us has used a footnote to signal an alternative position from the one arrived at in the body of the paper.

A fourth possibility is majority voting. Bright, Dang, and Heesen (2017) argue that scientific work should aggregate researchers’ judgments. Claims and propositions should be made in a paper that receive the assent of the majority of the authors. One might well find oneself outvoted in some cases, and this would be fine so long as there was agreement that voting had not produced a contradictory or logically incoherent set of claims.

A fifth possibility would be a kind of deliberative dictatorship: a lead author could write a paper, assign sections for others to compose, and bounce ideas off of possible co-authors. At the conclusion, all participants who agreed with the final product could sign on as co-authors, while dissenters could produce their own dissenting papers to be published alongside. This is related to proposals that might allow peer reviewers to receive more recognition for their work as initial gatekeepers.

Could all of these modes of co-authorship flourish in philosophy? Are some of them inimical to the discipline?

4.      Philosophers should co-author more of our work

Given the fact that some forms of collaborative recognition do exist, why suggest co-authorship as an alternative model for philosophy? Let’s start by dividing the reasons for co-authorship into roughly epistemic and roughly ethical categories, even if this is a division that is easily collapsed. Co-authored papers may simply be better for having multiple composers, readers, and researchers attached to them. The division of epistemic labor will often lead to better-written, more carefully crafted, or simply more copious publications: many minds make light work.

At the same time, co-authorship is partly about recognizing the contributions of our peers. In that sense, it is ethical. This is a weaker defense of co-authorship, since there are alternative methods for providing recognition. If a paper issues from a conversation with a colleague or a good objection raised at a conference or blog post, we philosophers would normally expect to mention that in a footnote, not to grant the colleague or objector co-authorship status. Philosophy papers are sometimes imagined to be the record of the thoughts or analysis of a single agent, and group agency seems much more difficult in these cases because we are so rarely in anything resembling agreement. We are rarely of a single mind, ourselves, so this is no big impediment, but this also ignores the fact that one can commit to a written product while having varying confidence in its disparate elements.

But there’s a significant ethical claim that might recommend co-authorship: the ideal of scholarly friendship. Co-authorship can be a way to channel professional philosophical relationships in productive ways, a norm for guiding conversations and arguments towards shared, potentially overlapping projects. There is independent reason to believe that shared projects are an intrinsic good tied closely to well-being. (Korsgaard, 1992) Thus we should, if possible, prefer to share the tasks associated with philosophical research with others, not just after publication but throughout the scholarly endeavor. Philosophical co-authorship is desirable just because philosophical friendship is desirable.

Shared projects are possible both between equals and between mentors and students. As such, co-authorship is a way to encourage productive collaboration within departments and with undergraduate and graduate students. In the pedagogy-first model of much philosophical research, departmental colleagues at most small schools should not co-author their research because this leads to overlapping areas of interest and knowledge. A department with only a handful of philosophers should instead hope that its faculty have as little in common as possible, even if they must share governance of their department and spend their careers working side-by-side. But if co-authorship underwrites philosophical friendship, then even a maximally pluralistic department should seek opportunities to co-create research, actively seeking agreement and shared methods, research areas, and conceptual terrain.

Like friends, co-authors need not agree on everything.[3] Finding some method for adjudicating those disagreements is important, but philosophical writing can encompass these minor dissents or majoritarian procedures, just as our departments do. The key is that the commitment to co-author—like the commitments of friendship—is a commitment to resolve disagreements using whatever methods are available. Friends do not obsess over decision-procedures, though we adopt them to ease tensions for the sake of shared projects. The same should go for co-authors.

Like friends, co-authors need not be equals. We see in the sciences that co-authorship allows a kind of scholarly mentorship, and in philosophy graduate students experience intense collaboration for the first time while writing their dissertation with a senior scholar. We even acknowledge that this is akin to co-authorship by treating dissertation advising as something close to co-authorship for some professional purposes.

More of this sort of mentorship should be encouraged. The practice of learning from another scholar does not end when a philosopher receives a PhD, and probably we shouldn’t pretend that it does. Perhaps newly-minted PhDs aren’t yet ready for the full burdens of a research program, or perhaps they would benefit from mentorship when they move on to a new research program. Or perhaps not: perhaps this would end with more domination by senior scholars, as the division of labor creates permanent hierarchies. But it’s not as if our current, academic political economy is hierarchy-free.

A final reason is merely accuracy: our authorial norms give a false idea of our practices to the rest of the academy. We should consider revising them to align ourselves with our fellow academics. Let’s not pretend that scholarly productivity metrics are irrelevant or that Deans do not look askance at our publication records compared to other disciplines.

Friendly Fire and Fiery Friendship: Noma Arpaly, Joseph Trullinger, and the Tenor of Philosophy Conversation

I often refer back to this post about a disagreement with Leigh Johnson over the role of critical engagement in philosophy. Using Gotthold Lessing’s Nathan the Wise and Hannah Arendt’s account of it in her Lessing Prize address, I described what I took to be the pleasure of disagreement in our profession:

Even when we retreat to our armchairs for solitary thought, we are not alone: we are drawn to each other because we share a commitment to these inquiries no matter where they may lead, and because we need the support of a community of fellow inquirers. The corollary is that, among philosophers, it is considered honorable to take on the position of devil’s advocate in order to introduce needed pluralism and distinction into a discussion. Among us, holding unfashionable views is needed and strangely satisfying. When we find ourselves at odds, when we begin to take what Dr. J calls ‘friendly fire,’ it is a reason to rejoice: our friends have arrived!

Johnson’s phrase has stuck with me over the years. I’ve often used it when welcoming correction, or when explaining why my own critical engagement with a friend is meant to be a sign of respect.

Is Polite Philosophical Discussion Possible?

I was reminded again of that exchange by Noma Arpaly’s excellent discussion of politeness (and rudeness) in philosophical debate. As Arpaly tells it, philosophers tend to violate two interrelated conversational norms, without distinguishing them: we are frequently rude, and we frequently engage in disagreement and correction. Among civilians, there is a strong non-correction norm that tends to go along with other norms like not hypothetically threatening or actually sneering at our colleagues.

Yet Arpaly wants to endorse violations of the non-correction norm, while preserving other norms of civil behavior. She creates an analogy to soldiers: the military requires soldiers to violate a widely held norm of pacifism–not-killing. But they must discipline soldiers not to thereby justify other norm violations–killing civilians and committing war crimes.

Having lost, of necessity, the inhibition against killing people, some soldiers find themselves shedding other moral inhibitions—and committing war crimes.

Having lost, of necessity, the inhibition against correcting people, some philosophers find themselves shedding other social inhibitions—and being terribly, terribly rude.

That’s just the nature of inhibition loss.

It’s a real problem. Arpaly counsels us to make the relevant distinctions and discipline ourselves all the harder on civility given that we’re already engaged in an unavoidable violation of the norm of non-correction. This seems exactly right.

Pleasure in Being Proved Wrong

On the Daily Nous thread on Arpaly’s piece, “Sam” writes:

Excellent post. I think there’s another, corresponding virtue worth cultivating here which could (cumbersomely) be called: “Pleasure in Being Proved Wrong,” the disposition to feel exhilaration when corrected by a polite (even if “frightening”) objector. The reason we should try to feel pleasure in being (politely and civilly) corrected, rather than embarrassment or humiliation, is simply that, as the author points out, this kind of correction improves our positions in ways that are nearly impossible to achieve by other means. In a sense then, objectors (provided they are not hostile or rude) are really just assisting the presenter towards a goal they both share (doing good philosophy). Of course, it’s essential that the objectors appreciate this shared goal as well, and present their objections accordingly. If all parties view successful objections as pleasurable, mutually beneficial exchanges rather than humiliating losses or merciless victories, there will be fewer frightened presenters and fewer rude objectors.

What I liked about Sam’s comment was that it seemed to endorse and extend the Arpaly analysis by saying, “Here is a way that we can endorse a norm of correction without endorsing rudeness.” That this is actually my view (I like to be corrected so I can be correct) made me doubly happy to see it percolate up in a comment from another person.

This is not to put the victims of philosophers’ rudeness on the hook for responding gladly to their behavior. The “glad to be (shown) wrong” norm applies equally to objectors and presenters; more to the point, it applies even more to rude objectors than to anyone else, who must prove they really do mean to correct and not just to humble the presenter. Arpaly endorses violations of the norm of non-correction: she is no pacifist, as she says.

But describing an attack (of the “What if I slap you?” variety) is rude in part because it puts vulnerable others in an uncertain position: they’re required to pretend that disembodied philosophers never would do what they say. But this goes well beyond violating basic civility: discomfiting one’s interlocutor does nothing productive at the level of correction and even interferes with shared inquiry. It’s not that we must sometimes violate basic civility in order to violate the norm of non-correction: it fails on both counts.

Many philosophical practices must be rethought in this light: interruption, for instance, is pretty obviously a violation on her view and on the “glad to be wrong” view. You don’t interrupt someone if you’re engaged in mutual beneficial exchange, because that assumes that you already know the outcome of that exchange. Nor do you ask questions that are really just coded assertions of error: you actually engage with the interlocutor about whether there are corrections to the (shared) position within the evolving inquiry.

We must, we must be friends!

For Arendt, the philosopher needs disagreeable friends in order not to be lost to the crowd’s violent enforcement of the non-correction norm. Philosophers need to disagree with each other so that we are not isolated by our disagreement. Thus, the norms of disagreement arise from the intrinsic good of intellectual friendships. As Arendt put it:

“[Lessing] was glad that… [truth] if it ever existed, had been lost; he was glad for the sake of the infinite number of opinions that arise when men discuss the affairs of the world.”

We wrestle with hard questions–take detours into difficulty–because it is our excuse to spend time together. For Arendt, the philosophical project may have some or another goal–to think what we are doing, for instance, or prevent nuclear war–but its true function is to give we disagreeable ones an excuse to reach out to friends like ourselves (alike in the virtues of agreeable disagreement.) It’s thus primarily a practice of friendship in homonoia, like-mindededness. This is what makes “friendly fire” palatable: that we have deeper bonds that salve the blows when we do not pull our punches.

My friend and former colleague Joseph Trullinger comments further:

Arpaly undermines the point with the war analogy, because it doesn’t go deep enough into the psychology informing the mood of the rude dude. Really, I think Arpaly is proposing something more like a “gentlemanly” duel in contrast to “unsportsmanlike” war, when it’s the martial virtues themselves that are the problem here. I think patriarchy instills in us (where by “us” I mean especially men, such as myself) this idea that the defense of one’s honor legitimates the use of aggression, but it is really putting lipstick on a pig. The fighting done to regain or steal away social standing is like sweeping leaves on a windy day, and it may in the first place be wrong to do. Philosophy has for too long patterned itself after polemos, war, and been polemics; I think there’s a reason Nietzsche’s depiction of the philosopher as warrior of ideas appealed to me more when I was a reedy hormonal teenager, as these sorts of self-descriptions appeal to men undergoing a crisis of masculinity. The issue is not that we have been “too soft” with ourselves and need someone from the outside to be “hard” on us. The issue is that we worship hardness itself at the expense of what we tell ourselves we’re defending with it. Here I draw a lot of insight from Simone Weil’s essay, “The Iliad, or the Poem of Force.” (h/t Joan Braune). Yeah, Achilles looks cool, and he takes offense over something trivial, but don’t get carried away with that pretext for allowing or gloating over more violence. Briseis is not the issue here, dude. Nor is it actually Achilles’ honor, or Agamemnon’s honor. It’s the idea that life is all about enforcing one’s life in the push and pull of force and counterforce. The intellectual “battlefield” is not the Iliad, nor should it be. Instead, we should foster the hospitality we see so many good examples of in the Odyssey.

TL;DR: less andreia, more xenia

Trullinger goes on to recommend that we replace my ideal of Arendtian “friendly fire” with a related one: “fiery friendship.”

It seems like an important point: too often in praise for “agonism” we tend to treat the conflicts as if they are self-justifying. We somehow need the agon to achieve the intrinsic goods of flourishing; we wrestle to develop strength and skill, which is the real function. We argue not because we are engaged in a collective project but because honing the arguments themselves is supposedly tied to the good life.

Trullinger reminds me that the “Pleasure in Being Proved Wrong” attitude requires more than just contention for the fun of it. Correction requires correctness; we cannot bracket truth for the sake of the infinite conversation and hope that that conversation will have the same character. Indeed, bracketing a shared commitment to truth-seeking leads to just the kinds of hurtful “games” that Arpaly rightly refuses to play.

Fiery Friendship and Philosophical Hospitality

In the backdrop here is the status of women in the profession. Arpaly suggests that the rudeness may be particularly off-putting to vulnerable participants, and that a move civil tenor will make the profession more welcoming. At least some of the masculinist norms of epistemic arrogance (interruption and “Well actually” and so on) have non-pathological roles to play in parts of our social lives. The really unprofessional thing is when we treat conference presenters the same way we treat our buddies or teammates.

Women, Arpaly suggests, are just as “glad to be wrong” as men. They too can violate the norm of non-correction in service of a shared inquiry. But the profession still doesn’t welcome them, and it demonstrates this inhospitable demeanor by treating philosophy as a game whose rules are constantly changed, or perhaps like hazing: where jocular rudeness and dishing out and receiving contempt are a part of how the game is played. This has the effect of protecting the space as a region of rough play–and certainly many women and other diverse practitioners can survive in such spaces, and many men cannot–but what would it mean to make it welcoming and inclusive?

Trullinger’s view seems to be that we ought to endorse the spirit of “glad to be wrong” by being particularly welcoming to those who are unlike us: those who are most likely to find the space of rough play unwelcoming, with whom we lack homonoia. True strangers are those who can offer us grounds for disagreement much stranger than mere contradiction.

I sometimes joke that we only ever hear calls for ideological diversity in political matters, and never Thomistic approaches to quantum mechanics or a nurse’s eye-view on bioethics. But Trullinger means what he says: he actually does want to see an expansive ideological diversity in non-political matters, to study Mexica metaphysics, queer philosophy of time, Byzantine logic, and Confucian epistemology.

Some desiderata: fiery friendship should allow joyful disagreement and also charitable agreement; it should offer opportunities for world-traveling and loving perception. It should be an avid fan of the unfamiliar. It should be glad to be proven wrong and it should be receptive–not just to correction but–to a complete redirection of our projects. It should welcome the vulnerable and make them strong. It shouldn’t punch down, or slap down, or suggest hypothetical down-slapping. It might even entertain actual pacifism, which need not be weak.
