IX. SCIENCE AND ORDINARY USAGE

39. There are many strange and exotic specimens in the gardens of philosophy: Epistemology, Ontology, Cosmology, to name but a few. And clearly there is much good sense -- not only rhyme but reason -- to these labels. It is not my purpose, however, to animadvert on the botanizing of philosophies and things philosophical, other than to call attention to a recent addition to the list of philosophical flora and fauna, the Philosophy of Science. Nor shall I attempt to locate this new specialty in a classificatory system. The point I wish to make, however, can be introduced by calling to mind the fact that classificatory schemes, however theoretical their purpose, have practical consequences: nominal causes, so to speak, have real effects. As long as there was no such subject as 'philosophy of science,' all students of philosophy felt obligated to keep at least one eye part of the time on both the methodological and the substantive aspects of the scientific enterprise. And if the result was often a confusion of the task of philosophy with the task of science, and almost equally often a projection of the framework of the latest scientific speculations into the common-sense picture of the world (witness the almost unquestioned assumption, today, that the common-sense world of physical objects in Space and Time must be analyzable into spatially and temporally, or even spatiotemporally, related events), at least it had the merit of ensuring that reflection on the nature and implications of scientific discourse was an integral and vital part of philosophical thinking generally. But now that philosophy of science has nominal as well as real existence, there has arisen the temptation to leave it to the specialists, and to confuse the sound idea that philosophy is not science with the mistaken idea that philosophy is independent of science.

    40. As long as discourse was viewed as a map, subdivided into a side-by-side of sub-maps, each representing a sub-region in a side-by-side of regions making up the total subject matter of discourse, and as long as the task of the philosopher was conceived to be the piecemeal one of analysis in the sense of definition -- the task, so to speak, of "making little ones out of big ones" -- one could view with equanimity the existence of philosophical specialists -- specialists in formal and mathematical logic, in perception, in moral philosophy, etc. For if discourse were as represented above, where would be the harm of each man fencing himself off in his own garden? In spite, however, of the persistence of the slogan "philosophy is analysis," we now realize that the atomistic conception of philosophy is a snare and a delusion. For "analysis" no longer connotes the definition of terms, but rather the clarification of the logical structure -- in the broadest sense -- of discourse, and discourse no longer appears as one plane parallel to another, but as a tangle of intersecting dimensions whose relations with one another and with extra-linguistic fact conform to no single or simple pattern. No longer can the philosopher interested in perception say "let him who is interested in prescriptive discourse analyze its concepts and leave me in peace." Most if not all philosophically interesting concepts are caught up in more than one dimension of discourse, and while the atomism of early analysis has a healthy successor in the contemporary stress on journeyman tactics, the grand strategy of the philosophical enterprise is once again directed toward that articulated and integrated vision of man-in-the-universe -- or, shall I say discourse-about-man-in-all-discourse -- which has traditionally been its goal.

    But the moral I wish specifically to draw is that no longer can one smugly say "Let the person who is interested in scientific discourse analyze scientific discourse and let the person who is interested in ordinary discourse analyze ordinary discourse." Let me not be misunderstood. I am not saying that in order to discern the logic -- the polydimensional logic -- of ordinary discourse, it is necessary to make use of the results or the methods of the sciences. Nor even that, within limits, such a division of labor is not a sound corollary of the journeyman's approach. My point is rather that what we call the scientific enterprise is the flowering of a dimension of discourse which already exists in what historians call the "prescientific stage," and that failure to understand this type of discourse "writ large" -- in science -- may lead, indeed has often led to a failure to appreciate its role in "ordinary usage," and, as a result, to a failure to understand the full logic of even the most fundamental, the "simplest" empirical terms.

    41. Another point of equal importance. The procedures of philosophical analysis as such may make no use of the methods or results of the sciences. But familiarity with the trend of scientific thought is essential to the appraisal of the framework categories of the common-sense picture of the world. For if the line of thought embodied in the preceding paragraphs is sound, if, that is to say, scientific discourse is but a continuation of a dimension of discourse which has been present in human discourse from the very beginning, then one would expect there to be a sense in which the scientific picture of the world replaces the common-sense picture; a sense in which the scientific account of "what there is" supersedes the descriptive ontology of everyday life.

    Here one must be cautious. For there is a right way and a wrong way to make this point. Many years ago it used to be confidently said that science has shown, for example, that physical objects aren't really colored. Later it was pointed out that if this is interpreted as the claim that the sentence "Physical objects have colors" expresses an empirical proposition which, though widely believed by common sense, has been shown by science to be false, then, of course, this claim is absurd. The idea that physical objects aren't colored can make sense only as the (misleading) expression of one aspect of a philosophical critique of the very framework of physical objects located in Space and enduring through Time. In short, "Physical objects aren't really colored" makes sense only as a clumsy expression of the idea that there are no such things as the colored physical objects of the common-sense world, where this is interpreted, not as an empirical proposition -- like "There are no nonhuman featherless bipeds" -- within the common-sense frame, but as the expression of a rejection (in some sense) of this very framework itself, in favor of another built around different, if not unrelated, categories. This rejection need not, of course, be a practical rejection. It need not, that is, carry with it a proposal to brain-wash existing populations and train them to speak differently. And, of course, as long as the existing framework is used, it will be incorrect to say -- otherwise than to make a philosophical point about the framework -- that no object is really colored, or is located in Space, or endures through Time. But, speaking as a philosopher, I am quite prepared to say that the common-sense world of physical objects in Space and Time is unreal -- that is, that there are no such things. Or, to put it less paradoxically, that in the dimension of describing and explaining the world, science is the measure of all things, of what is that it is, and of what is not that it is not.

    43. There is a widespread impression that reflection on how we learn the language in which, in everyday life, we describe the world, leads to the conclusion that the categories of the common-sense picture of the world have, so to speak, an unchallengeable authenticity. There are, of course, different conceptions of just what this fundamental categorial framework is. For some it is sense contents and phenomenal relations between them; for others physical objects, persons, and processes in Space and Time. But whatever their points of difference, the philosophers I have in mind are united in the conviction that what is called the "ostensive tie" between our fundamental descriptive vocabulary and the world rules out of court as utterly absurd any notion that there are no such thing as this framework talks about.

    An integral part of this conviction is what I shall call (in an extended sense) the positivistic conception of science, the idea that the framework of theoretical objects (molecules, electromagnetic fields, etc.) and their relationships is, so to speak, an auxiliary framework. In its most explicit form, it is the idea that theoretical objects and propositions concerning them are "calculational devices," the value and status of which consist in their systematizing and heuristic role with respect to confirmable generalizations formulated in the framework of terms which enjoy a direct ostensive link with the world. One is tempted to put this by saying that according to these philosophers, the objects of ostensively linked discourse behave as if and only as if they were bound up with or consisted of scientific entities. But, of course, these philosophers would hasten to point out (and rightly so) that

X behaves as if it consisted of Y's

makes sense only by contrast with

X behaves as it does because it does consist of Y's

whereas their contention is exactly that where the Y's are scientific objects, no such contrast makes sense.

    The point I am making is that as long as one thinks that there is a framework, whether of physical objects or of sense contents, the absolute authenticity of which is guaranteed by the fact that the learning of this framework involves an "ostensive step," so long one will be tempted to think of the authority of theoretical discourse as entirely derivative, that of a calculational auxiliary, an effective heuristic device. It is one of my prime purposes, in the following sections, to convince the reader that this interpretation of the status of the scientific picture of the world rests on two mistakes: (1) a misunderstanding (which I have already exposed) of the ostensive element in the learning and use of a language -- the Myth of the Given; (2) a reification of the methodological distinction between theoretical and non-theoretical discourse into a substantive distinction between theoretical and non-theoretical existence.

    44. One way of summing up what I have been saying above is by saying that there is a widespread impression abroad, aided and abetted by a naive interpretation of concept formation, that philosophers of science deal with a mode of discourse which is, so to speak, a peninsular offshoot from the mainland of ordinary discourse. The study of scientific discourse is conceived to be a worthy employment for those who have the background and motivation to keep track of it, but an employment which is fundamentally a hobby divorced from the perplexities of the mainland. But, of course, this summing up won't quite do. For all philosophers would agree that no philosophy would be complete unless it resolved the perplexities which arise when one attempts to think through the relationship of the framework of modern science to ordinary discourse. My point, however, is not that any one would reject the idea that this is a proper task for philosophy, but that, by approaching the language in which the plain man describes and explains empirical fact with the presuppositions of givenness, they are led to a "resolution" of these perplexities along the lines of what I have called the positivistic or peninsular conception of scientific discourse -- a "resolution" which, I believe, is not only superficial, but positively mistaken.
