Metadicursive Technology: Claims, Views, Arguments

This is the first post in what will be an ongoing series about what I like to call “philosophical technology” or, sometimes, “metadiscursive” or “metaconceptual technology” (since it’s not relevant only to philosophers). I said last time that the method of philosophy is just the method of inquiry, but in practice a lot of philosophy these days involves a lot of attention to the way we use words or concepts (more on that next time). Since that’s a thing that philosophers do, we need to have some conceptual resources for talking about ways of talking, or for thinking about ways of thinking. I like to refer to these resources as bits of technology to emphasize the fact that developing these resources requires some ingenuity and effort, that using them effectively involves a bit of training, and that they can be developed or improved over time. I like to emphasize that last part because, like a lot of philosophical work, progress in metadiscursive technology tends to become invisible once it’s been made.

Some bits of philosophical technology are pretty well-known to most everyone—distinctions, objections, counterexamples—though most people don’t think about them explicitly or as bits of technology for getting around. Introductory philosophy classes often cover some simple metadiscursive technology. Perhaps most commonly arguments, soundness and validity for arguments, and necessary and sufficient conditions. More specialized philosophy classes will often also cover such things as the analytic/synthetic distinction, and the difference between a priori and a posteriori or empirical knowledge (and whether and how those bits of technology are useful, or even make sense, is a subject of controversy among philosophers). Some classes will cover modality (roughly: necessity, possibility, and related notions) which comes in various forms—alethic, epistemic, practical, and others. All of these notions are examples of what I’m calling metadiscursive technology, tools that philosophers use to think clearly about the ways we reason. I won’t retread over all this well-worn territory here on Explicit Content, but I suppose I would if I were to write a big, heavy philosophy textbook or a philosophical field guide (that sounds fun, doesn’t it?). But I will talk about some other bits of technology that aren’t as commonly discussed, and that I’ve got something to say about.

To start off, though, I’m going to talk about something pretty basic: the difference between a claim, a view, and an argument. Although it’s simple it trips up a lot of students writing their first philosophy papers. And you might also think there has been progress here, since in the Greek of Plato’s time there was just one word, logos, which was used to describe each of these three things (as well as “word” and “sentence” and “speech.” But not “story.”). Because this stuff is so basic, the main body of the post may be kind of boring to anyone with some experience with philosophy, but in the interest of making things explicit I’m going to write on anyway.

First, a claim is the sort of thing that is expressed by a declarative sentence. A lot of what philosophers do is examine claims, and eventually commit themselves to affirming some of them, and denying others. (If you both affirm and deny the same claim then you’ve got a contradiction on your hands, and almost everybody thinks that’s bad.) “The mind is a nonphysical substance” and “Free will is not compatible with determinism” are claims that some philosophers have made. Claims are the sorts of things that can be true or false, or plausible or implausible. Some claims have become important enough that they get their own names. The second claim above is called incompatibilism. Another named claim is hedonism, which is the claim that “The only thing that is good for its own sake is pleasure, and the only thing that is bad for its own sake is pain.” Claims get more complicated when you consider that there can be claims about claims, and claims about arguments, and so on. For example someone might claim that “Hedonism is false,” or that “Incompatibilism is true because the consequence argument is sound.” But although consideration of claims is a necessary part of philosophy, the job of the philosopher doesn’t stop there.

Views are collections of claims that are supposed to be coherent. Views, like claims, can be true or false (though it’s more common to say they are right or wrong), and sometimes have names. Often a view is supposed to explain various things. For example, an old view called machine functionalism was supposed to explain why humans and octopuses can have the same mental states, like pain, where the view called mind-brain identity theory could not. Incompatible views may still share claims. For example, libertarianism and hard determinism are names for views about free will. Both the libertarian and the hard determinist believe in the claim that “Free will is not compatible with determinism,” but the libertarian is committed to the claim “We have free will,” and denies the claim “Determinism is true.” The hard determinist takes the opposite attitudes toward those other claims.

Views are often associated with the particular philosophers who explain them, like Ruth Garrett Millikan’s teleosemantics (roughly a view that meanings of words or thoughts, like biological functions, are determined by their causal history according to a process of natural selection). But popular views often fragment. Now teleofunctionalism is a word for a family of related views, like Millikan’s and Karen Neander’s. There is a folk caricature of philosophy that it consists in the elaboration of lots of different views, and that philosophers are people who know about lots of views and prefer some of them. But views are not the dominant currency of contemporary analytic philosophy, either.

The main business of philosophy involves giving and evaluating arguments. Arguments are what I focus on most when I teach philosophy, and there are a few different ways to describe them. The slogan that I’ve been using lately is that an argument is a reasoned defense of a claim. On this view (see what I did there?), arguments consist of two parts: a claim, called the conclusion, that the argument is supposed to support, and a reason that supports the conclusion. Philosophers use arguments to support claims (where the claim is the conclusion) and views (where the various claims that make up the view are conclusions, usually of different arguments). And just like there can be claims about claims, there can be arguments about arguments. For example, criticisms or objections about arguments are arguments about arguments (they are arguments that some other argument is bad). Opinion essays and most papers for classes are structured around a main argument (and usually contain other arguments). The conclusion of the main argument is what you call a “thesis” when you’re learning to write in school.

If arguments are reasoned defenses of claims, then you see that they are not bare statements of claims, and not disputes or questions or problems. Philosophilcal controversies, like the “mind-body problem” or the “problem of personal identity,” are not arguments in this sense because they do not have conclusions and they do not provide reasons. People make arguments for various views that resolve these controversies in different ways, but philosophers do not usually call the controversies themselves “arguments” (it gets confusing quickly).

Monty Python on arguments.

The most common way to model arguments in the analytic tradition is based on the form of a deductive inference in classical logic, or a syllogism in Aristotelian logic. Either way, the reason is made up of claims called premises that, if they are arranged right, support the conclusion through some rule or combination of rules (but rules are not just like more premises, as Lewis Carroll demonstrates in a well-known story). I say that logic models arguments, rather than saying that logic expresses arguments, since most philosophical arguments are given in the form of reasons, not in the form of logical deductions. But modeling arguments with logic can be very useful for determining whether the argument is good, and determining how an argument might be weak (undergraduates take note). Philosophers sometimes model their own arguments in logical form, and often model arguments in order to make clear objections to them.

It’s important to note that arguments cannot be true or false. Conclusions or premises, since they are also claims, can be true or false, but arguments have more complicated ways of being good or bad. Arguments can be valid or invalid, or cogent or not cogent, or sound or unsound, and so on. It would be tedious to explain what all these terms mean here (that’s taught in most introductory philosophy or logic classes, at least as they apply to deductive arguments, and perhaps inductive arguments). Basically, though, an argument is bad if it doesn’t give you a good enough reason to believe its conclusion, and the ways that reasons are bad are different and more complicated than being false.

There are at least three main ways to criticize arguments in philosophy. First, one can claim that the premises or presuppositions of the argument are untrue. That doesn’t make the argument “untrue,” and it doesn’t mean that the conclusion is false, it’s just one way that an argument might not give you reason to believe its conclusion. A second way to criticize an argument is to say that the reason doesn’t support the conclusion, regardless of whether its presuppositions are true. A simple example:

Edinburgh is in Scotland.
Humans often wear clothes.
Therefore, George Clooney is famous.

The premises and the conclusion are all true, but the premises don’t support the conclusion. They don’t give you reason to believe it. (However, this does not always make an argument invalid in classical logic… another reason to say that logic only models arguments.) A third way to criticize an argument is to claim that we have an independent reason to believe that the conclusion is false, and that this reason is better than the reason given in the argument. (But undergrads should note that it’s tricky to make a good paper out of a criticism like that unless you also figure out what specifically was wrong with the first argument, and explain it clearly.)

That’s a very brief and introductory pass at arguments, but arguments are complicated creatures and it can be difficult to understand all the ins and outs of how they work, especially when they are complicated or abstract (that’s why philosophy is hard). Or when they are about things that are difficult to think about clearly. But we deal with them all the time in life, whenever we are considering what to believe or what we should do. Whenever we consider what our reasons are, and whether they are good enough for believing or doing something, we are reflecting critically on arguments (even if we’re not doing it very clearly or explicitly). Even if not all philosophy is about arguments, critical examination of arguments is a central activity of philosophers, especially analytic philosophers. And while most disciplines do the same thing a lot of the time, philosophers are often the ones that are most concerned with developing the metadiscursive technology for doing so with self-conscious clarity and precision.

In fact, I think the skills of using basic metadiscursive technology are the most important things to teach in an introductory philosophy class, where many or most of the students do not intend to major in philosophy. Sure, it can be fun for some students to learn a bunch of views about free will or personal identity or ethics, but the most valuable and transferable skills for liberal arts students are the ones that are learned from sustained attention to arguments, and for the complicated ways of supporting and evaluating claims, arguments, and views.

The Method of Philosophy Is the Method of Inquiry

In my earlier post on the method of philosophy I made several negative claims: the method of philosophy is not based on intuitions or reflective equilibrium, it’s not random speculating, and it’s also not just about arguments. Today I’m going to motivate a little maxim that I’ve been mumbling to myself for a few years: that the method of philosophy is the method of inquiry.

What do I mean by ‘inquiry’? By ‘inquiry,’ I mean something like the deliberate project of understanding the world (including ourselves) better. Sometimes this is done in order to accomplish a specific goal, like curing polio or building bridges, and sometimes it’s not. I take it that building the Large Hadron Collider and looking for the Higgs boson is an example of the latter kind, although there have been highly practical discoveries along the way and this was always a part of the plan. At its best moments, the academy (I don’t mean the Academy, but academia, the worldwide system of universities and other institutions of higher learning) is an institution dedicated to furthering inquiry and disseminating the resulting understanding to students and others. I am tempted to think of inquiry as a distinctively human project (as far as we know). I don’t think that when a cat figures out how to use door handles it’s performing inquiry, but maybe we can say it’s a special kind of cat-inquiry as long as we recognize the differences between cat-inquiry and human inquiry. For example, the understanding gained from cat-inquiry does not tend to be disseminated among other cats, whereas human inquiry is a deeply social project.

It’s important, especially when we take into account the humanities and not just the sciences, that inquiry is about understanding of some sort, and not just truth or knowledge, narrowly construed. As I understand it, a lot of humanistic scholarship is concerned not with the articulation and justification of true claims, but of promoting a variety of ways of understanding things (texts, events, social structures). And honestly, that sort of thing goes on in science, as well. The psychological and linguistic literature, for example, are full of discussions that encourage readers (colleagues) to think about the mind or about language in a particular way. That is a lot of the force of, for example, theoretical discussions on embodied cognition, or descriptivism in linguistics.

(Another story I like to tell is that “philosophy” comes from the Greek, meaning love of wisdom, but that a lot of analytic philosophy seems rhetorically fixated on knowledge, scientific and otherwise, rather than some broader conception of human intellectual capacities.)

I believe that the method of philosophy is just the method of inquiry—that the acceptable methods in philosophical work are any and all of the acceptable methods in inquiry in general. To illustrate what I mean, I’ll talk a little bit about philosophy as a scientific discipline, and then about philosophy as a humanistic or perennial discipline.

Philosophy and scientific inquiry. Despite what you may have heard, philosophy and science are pretty tight. This is true in at least two ways. For one, a lot of contemporary analytic philosophy draws on empirical premises to make arguments. Hilary Kornblith is a good avatar for this practice in epistemology. Kornblith uses results in psychology and cognitive science to defend a particular picture of how we come to know things, and what our limitations are. This is also very true in my own specialty, philosophy of cognitive science. For example, Andy Clark draws on a variety of scientific results to argue for a picture of how humans and other cognitive subjects are embedded in the world (review), and Jesse Prinz draws on a lot of literature to argue for a particular view of emotion (review). Some philosophers even run their own experiments. So this kind of philosophy is not, whatever its faults may be, out of touch with science, and it does not claim to produce a priori knowledge (knowledge we can acquire without experience). But there is a second way that philosophy and science are closely related: scientific inquiry is based on philosophical methods like argument and conceptual clarification. The heart of any scientific article is an argument where the results of experiments or studies are presented as premises. The construction of scientific theories and models involves systematizing information from such arguments and refining the concepts of the theory so that knowledge can be represented perspicuously. In fact, you could say that scientific methods are a special case of philosophical methods.

Now, I am not claiming here that philosophy is better than scientific disciplines. I am just saying that, at bottom, we are all doing the same kind of thing. Craig Skinner (an interesting fellow) argued online last year that one function of philosophy as a discipline is to be a source for the ‘budding off’ of other disciplines, like the sciences. This is an interesting notion, but the ‘budding off’ activity makes more sense if there is at bottom a continuity between philosophical inquiry and other kinds of inquiry.

The tree of knowledge flowers and fades.

The perennial aspect of philosophy. A lot of contemporary analytic philosophy is on board with scientific inquiry, broadly construed. It sees itself as dedicated to the project of uncovering and justifying new knowledge and understanding through argument and reasoned speculation, just as science does. However, there is another dimension to some philosophy, which I am tempted to call the “perennial” side to philosophy (with apologies to Leibniz and Sellars and others, who meant different things by “perennial philosophy.” They meant philosophy about God and other eternal things, but I mean the philosophy that comes back year after year). Philosophy in its perennial mode engages with topics that are not suited to being settled once and for all, but that require repeated engagement. I think some ethics is like this—society changes, which means that the same ethical principles need to be worked out and again and again, but in new circumstances. This gives rise to topics like medical ethics, nanoethics, and ethical debate over privacy issues in the world of big data. I know less about humanistic inquiry than I do about science, but I suspect that this sort of effort to keep our understanding up to date with new developments, and to update our understanding of old developments, is of a piece with scholarship in the humanities. And there is an important perennial dimension to philosophy instruction. Even if no progress were made in philosophical research, I think it would valuable to help successive crops of students to question Cartesian dualism and free will libertarianism.

I also think that this is the sort of picture of philosophy that the later Wittgenstein had in mind when he defended his “therapeutic” conception of philosophy (the most famous remarks are probably §§115–128). Wittgenstein claimed that philosophy clears up the linguistic confusions that we encounter in life. I wouldn’t go so far as Wittgenstein here, but I think it is a part of philosophical inquiry to devise methods for getting around logical space without getting lost, and techniques for finding our way if we have. The perennial vision of philosophy is also championed by Richard Rorty. In a notorious discussion of Derrida’s work (“Philosophy as a Kind of Writing”), he criticizes the analytic philosopher’s “Kantian” conception of inquiry as narrowly knowledge-producing, and suggests instead that philosophers think of themselves as commentators in a great and interminable conversation about how to live.

Now, thinkers like Wittgenstein and Rorty have earned their share of stigma from more mainstream analytic philosophers. There are plenty in the analytic tradition who are uncomfortable with the perennial function of any inquiry, let alone of their own discipline, and respond by writing off their perennially-oriented peers as non-philosophers, or as not truly a part of the analytic tradition. There are several figures, especially at the University of Pittsburgh, the University of Chicago, and Harvard, who get this treatment. I am not claiming here that Wittgenstein and Rorty are right about philosophy. After all, my own research is of the more scientific kind described above (though it is Wittgensteinian in other ways). But I do think that they are not wrong about what they and many others do, and I think it’s cheap to reply by insisting that what they do is not really philosophy.

So what is philosophy? All this is to say that philosophy’s methods include those of other areas of inquiry. Sometimes philosophy uses the scientific method. Sometimes science uses philosophical methods. Sometimes philosophy functions to apply old views to new situations. Sometimes in philosophy we reimagine the old and familiar from a new perspective. So if there is any method to philosophy, I think it’s just the method of inquiry in general. Philosophers adopt a broad range of methods for understanding the world, and those methods seem to include, well, all of them.

But I think in the end this is an ecumenical conclusion (I like my conclusions ecumenical). If the project of philosophy is, at its broadest, just the project of inquiry, then that sits well with a lot of other things people have said about philosophy. It sits well with Plato’s old line that “Philosophy begins in wonder,” since the ultimate end of philosophy is to promote understanding. It also plays nice with the other claims of Plato’s Socrates, that philosophy is the means to the examined life, since a better understanding about how to live well is a special case of inquiry, and perhaps the most important one. My conclusion explains the central importance of argument to Plato’s Socrates, but also the importance of critical examination of assumptions and the development of tools for navigating logical space. My conclusion also sits well with Skinner’s suggestion that philosophy is a source for other disciplines to “bud off” from, since other disciplines represent more specialized approaches to inquiry.

Finally, I think my conclusions is a happy companion to Sellars’ famous dictum that “The aim of philosophy, abstractly formulated, is to understand how things, in the broadest possible sense of the term, hang together, in the broadest possible sense of the term.” Sellars continues that philosophy is distinguished from the special disciplines in that philosophers aim to keep track of the big picture (“It is therefore the ‘eye on the whole’ which distinguishes the philosophical enterprise”). I would say that that’s a nice regulative ideal, and it is something I try to do, but I doubt it’s a necessary condition. A lot of philosophers specialize quite narrowly, who are still philosophers. And people of many professions sometimes address philosophical concerns without necessarily reflecting on how their “bailiwick fits into the countryside as a whole.”

If this is right, though, there is a question left outstanding. What does that mean for the subject matter of philosophy? Surely if “leftovers” is too narrow a characterization, then “everything” is too broad! Not everything is philosophy, but I am not sure how to limit the subject matter because anything could be philosophy. Consider that Plato’s prescriptions about policy and social architecture belong to philosophy. Aristotle’s early biology is philosophy (even if it’s not great). Newton was a natural philosopher. Really, it’s one of the most frustrating things about philosophy that potentially anything can be relevant to anything. As a philosopher of cognitive science, I feel like I should know so much more than a human being ever could. I’ve got to manage my time and effort, of course, and it’s hubris to think that one person can be an expert in everything, or even (these days) in very many things at all. But I don’t think I can write off any sphere of human knowledge as clearly irrelevant to philosophy or even to my project. I never really get to say “That’s work for another department,” unless I mean that I just don’t have the skills or the time or the funding to look into it. But I never meant to claim that it’s my job to know everything (what a wonderful and terrible job that would be!). But any technique that anybody uses to understand the world better is a technique I could potentially find a use for in my line of work.
