VERY GENERAL FACTS OF NATURE

Lars Hertzberg

preliminaryversion31/5/07

In Philosophical Investigations 415 Wittgenstein gives what apparently purports to be a general characterization of his method in philosophy:

What we are supplying are really remarks on the natural history of human beings; we are not contributing curiosities however, but observations which no one has doubted, but which have escaped remark only because they are always before our eyes.

The remark occurs in the context of a discussion of the word “consciousness”. It has no obvious connection with the surrounding remarks. How is it to be understood? How general is its scope?

1. Concept formation: the simple story

Wittgenstein returns to this theme on just a few occasions. In Philosophical Investigations¸Part II, chap. xii, there are is a passage that brings to mind the one just quoted, although here Wittgenstein withdraws the claim that he is doingnatural history:

If the formation of concepts can be explained by facts of nature, should we not be interested, not in grammar, but rather in that in nature which is the basis of grammar? – Our interest certainly includes the correspondence between concepts and very general facts of nature. (Such facts as mostly do not strike us because of their generality.) But our interest does not fall back upon these possible causes of the formation of concepts; we are not doing natural science; nor yet natural history – since we can also invent fictitious natural history for our purposes.

I am not saying: if such-and-such facts of nature were different people would have different concepts (in the sense of a hypothesis). But: if anyone believes that certain concepts are absolutely the correct ones, and that having different ones would mean not realizing something that we realize – then let him imagine certain very general facts of nature to be different from what we are used to, and the formation of concepts different from the usual ones will become intelligible to him.

Wittgenstein here seems to be contrasting two approaches to the dependence of our concepts on facts of nature. One approach would be explanatory in the spirit of natural science: it would concern hypotheses about the causes of our having formed the concepts we have. It is not clear whether Wittgenstein thinks that such an investigation would be a meaningful undertaking. At any rate, it is not the type of investigation he is involved in. However, when one troes to get clear about the sort of investigation he does have in mind, it gets bewildering. The central notion is apparently the correspondence (Entsprechung) between concepts and facts of nature. What could this mean (since the notion of a causal connection has been ruled out)? Taking our clue from the next remark, the correspondence Wittgenstein has in mind, it seems, has to do with the correctness of concepts, with the idea that what concepts we have is an expression of our having realized certain things, and that the intelligibility of our coming to form one kind of concept rather than another is dependent on the circumstances in which concepts are formed.

This latter idea, however, appears to fly in the face of some of the core insights in Wittgenstein’s later work. The idea of concepts being “correct” or “incorrect”, or of their “corresponding” or “failing or correspond”to the facts seems alien to his thinking about language. Thus, in Philosophical Investigations 654-55 he writes:

Our mistake is to look for an explanation where we ought to look at what happens as a ‘proto-phenomenon’. That is, where we ought to have said: this language-game is played.

The question is not one of explaining a language-game by means of our experiences, but of noting a language-game.

And in Zettel 320 he writes:

Why don’t I call cookery rules arbitrary, and why am I tempted to call the rules of grammar arbitrary? Because ‘cookery’ is defined by its end, whereas ‘speaking’ is not. That is why the use of language is in a certain sense autonomous, as cooking and washing are not. You cook badly if you are guided in your cooking by rules other than the right ones; but if you follow other rules than those of chess you are playing another game; and if you follow grammatical rules other than such-and-such ones, that does not mean that you say something wrong, no, you are speaking of something else.[1]

Here, evidently, Wittgenstein is rejecting the idea of an independent measuring stick for checking on the correctness of our vocabulary and its attendant grammar. Accordingly, the idea of looking for a grounding for the concepts we use in our having come to realize certain things about our environment is misguided. Only against the background of a received way of classifying something, say, as an apple rather than a pear, or as red rather than orange,can there be an incorrect way of applying those classifications; the system of classification itself, on the other hand, is neither correct nor incorrect. Calling a whale a fish only became an error when a new way of classifying animal species had been adopted. The idea of concepts being correct or incorrect, evidently, makes no sense, and the notion that different concepts might be correct in different circumstances seems just another side of the same coin.

What, then, could be the relevance of natural history – real or imaginary – for our philosophical understanding of the ways we speak and think? And what issue is being raised by discussing the correctness of concepts? I shall try to get clearer about this in a roundabout way.

The question of how our concepts have been formed is of course intimately intertwined with the question of what it means to have concepts. The formation of what are we discussing? A good way of approaching that question, in turn, is to discuss what it means for an individual to acquire a concept.

One common way of reading Wittgenstein’s remarks about the acquisition and possession of concepts is succinctly described by Peter Strawson as follows:

Consider the case of somebody learning the meaning of a particular common word or, simply, coming to know what the word means. The followers of Wittgenstein are apt to speak of a preliminary period of training in the use … of the word… The point is that after a time the learner comes to find it utterly natural to make a certain application of the expression; he comes to apply it in a certain way as a matter of course… Here we may see one of the suspect pictures being, as it were, undermined…: viz. the picture of the learner’s application being governed by, or determined by, his acquired acquaintance with the abstract thing, its sense ormeaning…[2]

Further along Strawson writes:

The great point, on this view of the matter, is that there is, philosophically speaking, nothing at all behind this, and no need for anything beyond or behind it all to constitute a philosophical explanation of it. This is not to say that there are not biological and anthropological and cultural-historical explanations of how speech-communities agreeing in common linguistic practices came about. Such explanations there may well be. But as far as the philosophical problem is concerned, the suggestion is that we can just rest with, or take as primitive, the great natural fact that we do form speech-communities…; that we have, if you will, a natural disposition to develop the dispositions which qualify us for … the description … “members of a speech-community, agreeing in a common linguistic practice”.[3]

We may note that “facts of nature” are only given a minimal role here. The only relevant fact of nature is that we are beings who are disposed to form speech-communities. Of course, Strawson admits, biological, anthropological and historical circumstances play a role, presumably affecting what particular conceptual schemes are actually developed, what similarities are accorded importance, etc. However, we can “divide through” with them:these are just contingent details having no bearing on the philosophical problem, which, for Strawson, I take to be this: what kinds of entities do we need to invoke in order to account for the fact that speakers are able to acquire concepts?[4]

On Strawson’s account, then, the only philosophically relevant variation would be between beings who are by nature disposed to form language-communities and beings who are not. However, this does not touch on the question how, given that a community does have concepts, imagining different facts of nature might render wholly different concepts intelligible. This seems to me to be connected with anotherpoint in Strawson’s argument: for him, the problem of concept acquisition seems, roughly, to be the problem of learning to classify things correctly. The learner encounters a set of examples of the application of some class, say, “red” or “apple”, and the question is how she learns to go on in the right way. Wittgenstein remarks that there is nothing about the particular red things or the particular apples that will make her go on in the way we mean her to; we cannot explain the success of our instruction by saying that the learner understood that the relevant property was that of being red or being an apple, since that would presuppose that she already had command of the classes that we were trying to convey to her (and, indeed, of what it means to classify things in the first place). More generally, there is no ground for our going on in one particular way rather than another, we simply do.

Undeniably, the discussion of how we acquire classifications – what we might call the recognition problem – has an important place in the Philosophical Investigations. It is closely connected with some of the central discussions of the early parts of the book. The realization that there are no guarantees that people will go on applying examples in the same way, and that, in this sense, it is by the grace of nature that people manage to stay on course, is one point (though not the only point) made through the discussion about continuing a series of numbers (Philosophical Investigations 143-155)[5].

Not only is this an important theme for Wittgenstein. From large parts of the Philosophical Investigations one may get the impression that it is the central issue where language-learning is concerned. Sharing a language, it seems to be suggested, is simply applying words in the same way. To get clear about the recognition problem, then,is to become clear about what it means to speak a language. PI 242 is often quoted as an expression of this view: “If language is to be a means of communication there must be agreement not only in definitions but also (queer as this may sound) in judgments.” PI 206-208 are often read along the same lines. Thus, in her commentary on the Philosophical Investigations Marie McGinn writes:

Our concept of language describes … a particular form of life, namely, one that displays the characteristic regularities or patterns that constitute the following of rules. Central to the idea of the form of life that our concept of language picks out is that there exists a pattern or structure in the activity of using words which fixes what counts as applying the words of the language correctly or incorrectly… The agreement or harmony that Wittgenstein suggests is essential to our concept of language is the agreement that constitutes the characteristic form of life that speaking a language … consists in.[6]

Now I do not find anything wrong with this account as far as it goes. The critique of the idea that concept acquisition consists in the grasping of certain abstract entities is certainly justified and is obviously something that Wittgenstein intended to put forward. However, I would argue that there is more than this to the contingency of our concepts on very general facts of nature, and that what is left out in this account is as important as what is included. There are two sides, I want to argue, to what is left out: there is, on the one hand, a negative story (or at least suggestions of one), i.e. a story about the way the facts might pull the rug from under our linguistic practices, and, on the other hand, a positive story, i.e. a story about how language comes to have a place in our lives. I shall discuss these aspects in turn. After that, I shall discuss what we may take to have been the point of these stories: what were the questions that Wittgenstein was concerned to resolve?Was Wittgenstein, in some sense, a naturalist? What I wish to suggest is that he was not attempting to formulate a competing theory about concept formation; rather, for him, appeals to real – or imaginary! – facts of nature was part of an attempt to change our ways of thinking about language.

2. Rug-pulling facts

In Philosophical Investigations 142, Wittgenstein writes:

… if things were quite different from what they actually are --- if there were for instance no characteristic expression of pain, of fear, of joy; if rule became exception and exception rule; or if both became phenomena of roughly equal frequency ---- this would make our normal language-games lose their point. – The procedure of putting a lump of cheese on the balance and fixing the price by the turn of the scale would lose its point if it frequently happened for such lumps to grown or shrink for no obvious reason. …

In a note inserted in the manuscript, obviously connected with this remark, Wittgenstein writes:

What we have to mention in order to explain the significance, I mean the importance, of a concept, are often extremely general facts of nature: such facts as are hardly ever mentioned because of their great generality.

(We may note that these remarks immediately precedethe discussion about learning to continue a number series.)

Precisely how are we to understand these remarks? In fact, the conclusion Wittgenstein draws from these thought-experiments is strangely cautious. What would be undermined if certain very general facts of nature were different, he is suggesting, is the importance,the point, of certain concepts or language-games. He seems to be suggesting that they could still exist, they wouldsimply recede to the background. Yet in many cases it is not clear what it would mean to distinguish importance from intelligibility. In the case of determining the price of a lump of cheese with the help of a scale, the question of whatsomeone is doing and why he is doing it can hardly be separated. If there were no point to the procedure, there would be no distinction between a correct and an incorrect way of doing it (assuming, of course, that it is not part of some other practice, such as a ritual). So if lumps of cheese were to start growing or shrinking unpredictably, it is not just that we should stop weighing them; there would, in a strict sense, be no such thing as weighing a piece of cheese; i.e. whatever someone was doing in placing it on a scale would not be described in those terms. Of course, if the same thing were true of products in general, of people, rocks, heaps of sand, cups of liquid, etc, the concepts of weight and scales would lack application, and thus intelligibility, altogether.

There is a similar obscurity in some of the remarks inOn Certainty. In513-14, Wittgenstein wrote:

What if something really unheardof happened? If I, say, saw houses gradually turning into steam without any obvious cause; if the cattle in the fields stood on their heads and laughed and spoke comprehensible words; if trees gradually changed into men and men into trees. Now, was I right when I said before all these things happened “I know that that’s a house” etc., or simply “That’s a house” etc.?

This statement appeared to me fundamental; if it is false, what are “true” or “false” any more?!

Wittgenstein is trying to describe a situation in which our practice of judging would be plunged into chaos. But do we really understand the description? Suppose it seemed to me that something that looked like a cow was laughing or speaking comprehensible words, it is not clear what my response would be. Would I still call it a cow? Would I conclude that the sounds really came from the cow? How would a laughing cow sound? And in what sense would what the cow said constitute comprehensible words? Am I to imagine the cow parroting words, or actually speaking and responding in ways that make sense from the cow’s point of view (and whatever would that be?)?What language would it speak? What tone would it use?

Rather than “what are ‘true’ or ‘false’ any more?”, should Wittgenstein not have asked “what are ‘cows’and‘trees’ any more?”? He says that what characterizes our ways of judging is that in such a case all our certainty would vanish (just as in the case of the cheese, the point of the practice would dissolve). Yet it would, it seems, be more to the point to say that what characterizes our ways of judging is that we could not imagine circumstances that would lead us to describe what was happening in such terms.[7]

It appears as if Wittgenstein were saying that, in one case the importance of the language-game, in the other case its certainty, were external to the sense of the game.If this were so, that would indicate that Wittgenstein is still in the grip of a strand of thought that runs through much of Western philosophy: the notion that, however the world may twist and turn, our ideas or concepts or words will never leave us in the lurch: there will always be an intelligible way of describing what is happening.[8] Classical cases in point are Descartes, who saw no problem in using the words “dream” and “awake” in formulating the supposition that we might be dreaming when we take ourselves to be awake, and Hume,who thought we should have no difficulty identifying ordinary objects even if they seemed to behave in what, for them, would be extraordinary ways.
