The History and Phenomenology

of Science is Possible(1)

Lester Embree

 

We observe throughout, and the observation still holds today, that science and philosophy are two separate things; that one may be an excellent scientist without having the least idea of what one is really doing. It is even almost always thus. —Alexandre Koyré (11: 35)

 

It is difficult to deny that “science” is to our society and era what religion seems to have been in the middle ages. A philosopher cannot responsibly ignore so central a feature of his culture. After I had my training in phenomenology at the Graduate Faculty of the New School in the 1960s and came across the Hudson to America, I did look at Ernst Nagel’s work but could not phenomenologically get a grip on it or the style of philosophy it represents.(2) At Northern Illinois in the early 1970s I was, however, fortunate to be in contact with Harold Brown while he studied the new philosophy of science (cf. l) and thus I heard of the work of Stephen Toulmin, Norwood R. Hanson, Paul Feyerabend, etc. and became especially interested in Thomas Kuhn’s work. This new style has a large role for knowledge of how science has actually been and then, through study of Kuhn’s theoretical and methodological efforts within the newly professionalized discipline of history of science, I am now finding a way to phenomenologize about science. At present I am conducting a large sociohistorical study of powerful movements in current ethnology and archeology as part of an attempt to develop a phenomenological philosophy of human science partly based on a living case of how science is actually done by groups over time, but this is not the occasion to present that effort. Rather, the present paper is devoted to sketching how Kuhn’s thought can be appreciated phenomenologically. As such this is an eccentric summary of a larger work in preparation possibly five times its magnitude. To keep some philosophical options open, I have changed the announced title from “Phenomenology and the Sociohistory of Science.” I do not see any reason why reflection on science having recourse to the historiography of science should be the exclusive province of non-phenomenological philosophy, particularly since science has been a central issue for phenomenology since the beginning of the century. “History of Science” in the above title designates the work of Thomas Kuhn and my contention is that his work can be of use for a constitutive phenomenology of science. “Science” for Kuhn is theoretical natural science, but I suspect that at least his general approach can also be taken to human, formal, and even philosophical science, not to mention technology and other disciplined collective endeavors. We can best enter Kuhn’s thought through his contrastings of “old” and “new” images of science as they have historically been accepted on three levels.

 

 

1.   Images of Science

 

(1) The least emphasized but possibly most ultimately interesting old image of science relates to the standpoint of the practicing scientists themselves. It is about what heroes of science accomplished and relates to the actual facts of past science about as well as a tourist brochure relates to a national culture. As a false image it obfuscates how science is the activity of groups rather than the results of solitary individuals, how science is usually close-minded rather than open-minded, how normally facts are fitted to theories rather than vice versa, and how natural science is theoretical research and thus different from technology. This old image plainly has value for science in the wider practical world and is naively accepted on the margin of the consciousness of scientists as they thematize the theoretical issues at hand, write chiefly for one another, and do not seek to understand their own endeavors in a scientifically historical manner. This mythical image is projected in popularizations, where exciting episodes and heroic deeds are emphasized, but it is also perpetuated if not perpetrated in science textbooks. Kuhn does not advocate altering the nature and role of such textbooks where the education of scientists is concerned, although the impact they have on philosophers, historians of science, and the lay public who basically know science through them seems another question.

(2) On a second level, Kuhn emphatically contrasts old and new images of science in the history of science. Historically there has been some variety in the old historiography of science. Since antiquity, some scientists have withdrawn from research and engaged in chronicling for its pedagogic and professional-promotional advantages. Plainly this is related to the image of science just referred to. Such in-house historiography tends to focus on single sciences as well as single scientists. Other varieties of the old science historiography have been done by philosophers, especially since Bacon, have tried to view science as a whole, and were optimistically concerned with the alleged progress of reason. Both sorts of old image involve faith in the continuous and piecemeal cumulativity of scientific advance. And in the light of the current scientific “truth,” past discoveries are celebrated and errors deplored. (Presumably, if—or “as”—that “truth” changed, history would have to be rewritten.)

Against all that, the new history of science was begun in the United States after World War II by Alexandre Koyré (it seems to me that in relation to Koyré’s “Copernicus” Kuhn is playing a fascinating “Kepler”). The new historiographic image of science came from Continental Philosophy (although Kuhn fails to mention his maître Koyré’s maître Husserl) as well as from work in the history of philosophy. In ugly but I hope useful terms partly of my own devising, Kuhn contends that the old science historiography is what I call “presentistic” (since it involves approaching the past in the light of present science) and that the new science historiography is “pastistic” (because it would have us comprehend old science in the formerly contemporary but now past terms and contexts in which it arose). The “presentism” of the bad old way is objectionable, for example, in projecting today’s philosophy/ science opposition into ancient thought where it did not exist, in separating religion from science in times when they were much involved with one another, for doing similarly for science and technologies such as astrology, calendrics, etc., as well as simply misreading much of what happened. Something of how the new and good “pastistic” history of science is done will be suggested later in this essay.

(3) A Ph.D. in theoretical physics, Kuhn trained himself in the history of science, where he has focused his efforts, at least in his published work, on the broader methodological and theoretical questions in his new field; despite the appreciation his thought has been receiving for some twenty years in the philosophy of science, he nowhere claims to be a philosopher.(3) Nevertheless, if one looks for them, one can find many objections to the old image of science that was accepted in the old philosophy of science. This is of coarse Positivism cum Logical Empiricism and to some extent also Popper’s Falsificationism. Tested against the historical record (“pastistically” considered, of course), the image of science in the old philosophy of science, which stems from textbooks and the old history of science, is discontinued or falsified. (It is ironical, of course, that positivism be afflicted with mythological notions of science!) In opposition specifically to Logical Empiricism, Kuhn wants a large place for the context of discovery and, more generally, attention to the dynamics of the scientific process as much as to the logic of results, concern with the semantics as well as the syntactics of scientific utterances, and recognition that there are definite limits to what can be reconstructed logically in terms of rules and criteria. On the problem of scientific development, which he contributed much toward making currently focal, Logical Empiricism seems to model all of science as continuously cumulative on “normal science” and Falsificationism to model it all on revolutionary episodes, while for Kuhn there is a model which covers both phases of science (this will be discussed briefly in the section after next). In the more recent philosophy of science, he has been pleased to see the past of science taken more seriously, but complains that it is still too much done, in my terms, “presentistically.” Although he certainly has yearnings and interest, Kuhn does not have a new philosophy of science springing from his head. The present essay is to suggest that his historical work can be of use for a new (but “old”) phenomenological philosophy of science.

 

 

2.   The   Human  Science  of   Science

 

Kuhn’s approach to science can be distinguished from his specific analyses and should the latter be mistaken, the former might still be valid. For this approach, science is thematized as a collective human activity. This focus does not render the objects and results of the activity irrelevant, but it does represent a shift in relation to earlier views. One does not engage, unreflectively in propositional analysis and logical reconstruction so much anymore. Literature, painting, music, philosophy, law, technology, etc., have long been regarded as activities and Kuhn claims originality only for applying that approach to science; this seems how he makes Koyré’s revolutionary “pastistic” model work. If natural science is a collective activity, it can be approached in a variety of ways, all of which I would consider “human scientific.”

(1) If psychology is about individual outlook and behavior, some of what Kuhn does is psychology. He studied the Gestaltists and Piaget very early in the development of his position. He distinguishes between individual idiosyncrasy and traits that are typical of individuals of a class; thus the specialist dedication of Copernicus is typical, while “Newton’s remarks about the role of hypotheses in science were dictated by personal idiosyncrasy as often as by philosophical acumen; repeatedly he renounces hypotheses simply to avoid debates” (14: 45). The typical psychological traits, however, interest Kuhn most; thus the chief force preserving the Ptolemaic system at a certain point was conservatism and the old cosmology of two spheres satisfied a psychological craving for at-homeness. More generally, there are psychological differences between research scientists and technological inventors, not to speak of between philosophers and historians, and among natural scientists there is both dogmatism and openness, which have difficulty psychologically coexisting within individuals. Finally, the ways in which scientists react to change in their fields varies individually in typical ways; some do not adapt at all and one simply waits for them to die off. (Some in the new philosophy of science say that they are waiting for the old guard there to die off!)

(2) Kuhn’s involvement with sociology came late and, though he is familiar with current sociology of science, on which he is having an impact, his own interests are narrower and his views seem his own. He has some interest in the function of institutions, but his focus is on how groups do science; thus, if science is a collective endeavor, simultaneous discoveries—a problem for the old science historiography, where the individual is fundamental—are not surprising but rather to be expected among those with the same training, outlook, and problems. Again, there is less need to posit psychological conflicts within individuals when a group can contain varying proportions of dogmatic and open individuals and small changes on the part of many can transform the consensus dramatically. The groups that do science are regularly called “communities” by Kuhn, which may connote the intensity of communication within them, but not their size, which he estimates as between twenty-five and one hundred, something which was probably obvious before the 20th century and what might be called “mass science”; plainly there are limits to how many others one can know and whose work one can keep abreast of. Science groups are then narrow specialties, the members of which share much in the way of education, professionalization, etc. This is the unit for Kuhn’s analyses and fascinating for me. Copernicus worked in a small group devoted to technical mathematical astronomy (who else could read De Revolutionibus?) and Galileo is to be understood in relation to his teachers, contemporaries, and immediate successors. Hence, specialties are structured in social successiveness as well as simultaneity. Despite what might be called the primacy of the group, there are roles which-individuals can be seen to .play within group life, e.g., newcomer, student, precipitator, consolidator, hold-out, etc. But what do the specialities as wholes composed of interrelated individuals do? Nothing less than produce and validate knowledge in their respective domains (cf. 9).

(3) Linguistics and hermeneutics naturally come in for Kuhn because of the prominence of communication in the doing of science and of texts in the historical study of it. He was early influenced by B. J. Whorf and later drew on linguistic studies of verbal interaction in the laboratory and of the translation process. Members of specialities have their own dialects, which must be mastered. While Kuhn ran a huge oral history project on Quantum Physics, he favors work through texts for access to the stretches of time over which scientific change would seem most apparent. He discusses change in literary genre, particularly the rise of the article form, he praised and practiced the technique of explication de texte emphasized by Koyré, and he has recently become especially concerned with the problem of choosing among different readings of a text.

 

[T]he search for the best, or best-accessible, reading has been central to my historical research (and has also been systematically eliminated from the narratives that report its results). Lessons learned while reading Aristotle have also informed my readings of men like Boyle and Newton, Lavoisier and Dalton, or Boltzmann and Planck. Briefly stated, those lessons are two. First, there are many ways to read a text, and the ones most accessible to a modern are often inappropriate when applied to the past. Second, that plasticity of texts does not place all ways of reading on a par, for some of them (ultimately, one hopes, only one) possess a plausibility and coherence absent from others. Trying to transmit such lessons to students, I offer them a maxim: When reading the works of an important thinker, look first for the apparent absurdities in the text and ask yourself how a sensible person could have written them. When you find an answer, I continue, when those passages make sense . . . then you may find that more central passages, ones you previously thought you understood, have changed their meaning. . . .

What I as a physicist had to discover for myself, most historians learn by example in the course of professional training. Consciously or not, they are practitioners of the hermeneutic method. (13: xii)

 

This  hermeneutical method is essential  to Kuhn’s “pastistic” approach to the past of science and it is more like the traditional hermeneutics that Thomas Seebohm, for example, currently advocates (it could, I suppose, be called the “old” hermeneutics) than the new and violent hermeneutics of Heidegger and his school.

(4) The specifically historical component of Kuhn’s approach is naturally the largest and most pervasive, thus perhaps the most accessible and familiar, and hence probably the most cursorily treatable here. But it should be mentioned that for Kuhn history in general and history of science specifically are cognitive endeavors, endeavors which are empirical in their own way and which aim at objective and verifiable results. As a “Continental,” I have no difficulty recognizing such to be Wissenschaft, but of course Geistes- rather than Natur-. And not only can the historian develop factually descriptive narratives, but it seems that he can also develop explanations. In other words, while they are not of the covering-law type, there can be dynamic models of historical events which are structural in that the same types of events not only have the same sequences on different unique occasions (the “structure of scientific revolutions” is at least such a typical sequence, but may be more than that), but also, it seems, dependency relations can be posited among events of the repeated types. The following passage would seem to express such a low-level explanation (note that he is speaking about collective work).

 

A contemplative immersion in the words of pioneers and their contemporaries may reveal a subgroup of factors which seem more significant than the others, because of their frequent recurrence, their specificity to the period, and their decisive effect upon individual research. The depth of my acquaintance with the literature permits, as yet, no definitive judgments. Nevertheless, I am already quite sure about two such factors, and I suspect the relevance of a third. Let me call them the “availability of conversion processes,” the “concern with engines,” and “the philosophy of nature.” (13: 72)

 

Since the quotation summarizes the answer to the question, “Why, in the years 1830-50, did so many of the experiments and concepts required for a full statement of energy conservation lie so close to the surface of scientific consciousness?” the account is explanatory, even though at a low but not quite particularistic level. Kuhn also has interesting views on unifying interna1istic and externalistic historical approaches, but these can be discussed on another occasion.

In sum, Kuhn thematizes science as a collective human activity done by relatively small groups of specialists and the manner in which he thematized it is human scientific in a multidisciplinary way. This is certainly more interesting than a mixture of Humean psychology and Russellian logic. And indeed, the way in which scientific objects are considered in relation to human activities can even be considered in a general way phenomenological.

 

 

3.   Paradigms  and  Revolutions

 

Kuhn is best known, most discussed, and most self-interpretive with respect to his claims about how natural-scientific specialties arise and develop through immature, normal, and revolutionary phases. Since this is well known, let me confine myself to but two comments on this occasion. (1) While he has been attacked for vagueness if not equivocation in his usage of the word “paradigm,” I find no problem reading that word (“pastistically”) with narrow and broad significations and hence find that his self-explication of these significations as “exemplar” and “disciplinary matrix” is no more than a verbal advance. What might be called the “Kuhnian strategy” consists in first identifying the scientific specialty and second seeking its disciplinary matrix. This disciplinary matrix is “all the objects of group commitment” (13: 297), and includes on Kuhn’s analysis (a) the symbolic generalizations and perhaps all of the special terms), (b) the models, and (c) the exemplars, i.e., the concrete problem solutions (which is what “paradigm” in the narrow signification signifies). Given how much attention he pays them, however, and even though he does not include them in his list, it seems to me that we should add (d) values to this taxonomy and I would further suggest adding (e) the equipment specific to a specialty at least in how it is employed. With these inclusions, the disciplinary matrix is rather like the correlate of a Diltheyan Weltanschauung, with its affective and conative as well as cognitive components.

(2) For any who have not heard of it, let me point out that for Kuhn natural science at least typically develops through an immature stage given to much strife among schools to maturity when a disciplinary matrix is settled upon and becomes the unproblematic background for research. Within mature science there is then “normal” scientific research in which the group has a confident consensus about what it will find and proceeds to run (and re-run) experiments to confirm what it is already committed to. Under certain conditions, however, difficult puzzles become less and less ignorable and demand attention as anomalies, the speciality goes into crisis and the taken-for-granted background becomes problematic, there can be desperate resort to almost anything (even philosophy) until eventually a new disciplinary matrix is established as an unproblematic background for group commitment and normal rather than extraordinary research can be done once more.

Such episodes of scientific revolution usually occur, however, without the scientists being aware of them; it seems that they could occur in the lives of individual scientists, but they typically involve entire specialties (and can have aftermaths elsewhere, as the Copernican Revolution had); and they are fairly frequent events in the history of science. This model of change seems plausible in the light of the events Kuhn refers to, which come from modern and contemporary natural science, but it should—I believe—be taken as hypothetical and tested in quite concrete empirical sociohistorical research. Much of the “paradigm talk” I am acquainted with in social science as well as philosophy of science seems not only blind empirically but also in the service of competing schools of thought. It is of course an intellectual vice to talk so much without looking, but perhaps these behaviors are a confirmation of Kuhn’s view, just as any tendency of specialists in the philosophy of science to remember the full range of philosophical problems would be now that there is revolutionary conflict between old and new approaches.

But the value for philosophy of science of Kuhn’s multidisciplinary approach, which emphasizes the human activities correlative to scientific objects, should not be tied to the fate of his daring hypothesis about revolutions. And, while Kuhn has doubts about the application of his revolutions model to the social sciences, because they do not yet seem to have become mature (but I wonder whether anyone has looked closely enough), his general approach remains applicable there and, even more broadly, to all the human sciences; his own remarks in the perspectives of intellectual autobiography and the past of science historiography itself already seem to fit the model.(4)

 

 

4. The Idea of a Reflective Account of the Constitution of Science

 

In constitutive phenomenology, objects are accounted for through reference to the “consciousness,” in a broad signification, to which they appear and in which they are construed. Perhaps the words “intentive life” connote better something which has affective and conative elements, is largely and basically unreflective, and is, as the slogan has it, “always consciousness of . . .” (which we can re-express as “all intentive processes are intentive to . . .”). It should already be plain that Kuhn’s collective human activity in scientific specialties is an intentive life and is intentive to a disciplinary matrix. Plainly, one can consider such activity with respect to how it is intentive to . . . and how such a matrix is what it is for the scientific specialty. To consider such a dual matter in such a manner is, in a broad signification, to “reflect” on it; thus “pastistic” science historiography would be specifically reflective. If Kuhn had identified the disciplinary matrix with the research activity, he would have been guilty of some sort of a psychologism, but, even though he does not see the problem of relating them (much less how to solve the problem with Intentionalität), he does keep them distinct. Given how there is an interrelated multiplicity of subjects in a specialty, we can go even further beyond his letter to pose the problem of the intersubjective constitution of public (“objective”) objects. If Kuhn also consciously distinguished description and explanation and recognized the logical priority of the former, then he would be even more phenomenological, and he does seem unwilling to abandon the theoretical/ observational term distinction and I have heard him argue for the priority of taxonomy, which I at least readily comprehend as eidetic description. To the degree that his general approach can thus be comprehended as reflective and descriptive and regardless of whether it is factually or eidetically descriptive (or both), it can indeed be considered in the broad signification phenomenological. There is no sign that Kuhn ever took seriously the possibility of a transcendental grounding of science or the world it is about, but then one should not expect a human scientist to question the natural attitude (it is difficult enough to get philosophers to do so!). I see no difficulties of principle, however, with transposing mundane findings to the transcendental plane. Science specialties (including those in the history of science) would then be transcendental intersubjectivities, whether they knew it or not.

If Kuhn’s work might thus be considered at least compatible with constitutive phenomenology, it might be well to consider some specific ways in which a phenomenology of science might not only benefit from the history of science but also help it in return. Where the way in which specialties might be considered collectively intentive to disciplinary matrices is concerned, phenomenological reflection on the affective and conative elements in intentive life as well as in the lived situation of the scientists could help compensate for the intellectualist emphasis in most analyses of science.(5) Of course, Husserl’s many reflections on the foundation of scientific knowing in life-worldly experience is relevant (10). Beyond Husserl, let me suggest that Gurwitsch’s reflections on the theme/thematic-field/margin structure, including the notion of “orders of existence,” (7) and Schutz’s work on the finite provinces of meaning in scientific contemplation should be of use in the elucidation of disciplinary matrices and how they are, in the phenomenological signification, “constituted” (17). Also, a phenomenological sociology of science can be extracted from Schutz’s thought without too much effort.

For Kuhn, when a scientific revolution occurs, the “world,” if it might be called that, of the scientific specialty appears differently, even on a perceptual level, to the researchers (and this as well as theory can affect the practical world in which we live profoundly). I wonder whether any philosophy other than constitutive phenomenology is so prepared to be shown that one and the same nature appeared differently to different groups in different eras, e.g., the Ptolemaic and Copernican views of the solar (or “terrestrial”) system? But this is a descriptive matter, where the visions of the specialties are concerned. One can well imagine that the human scientists who investigate science would want to explain how the collective living of disciplinary matrices changes and does not change. Such knowledge could have technological value for science policy since the conditions for fostering and for impeding scientific productivity would be sought. There is a model in Gurwitsch for a natural-scientific psychological explanation of individual change which could be reinterpreted human-scientifically for a sociohistory of science and might help in this connection.(6)

The general problems that now chiefly obtrude for me in relation to the tasks of a phenomenological philosophy of science involve the specific knowledge that can come from a descriptive sociohistory of science. Otherwise, general problems of rationality, evidence, etc., can only be attacked in dubious a priori ways. For example, I would like to know what the essential difference is between theoretical science and technology. I would also like to know whether there is a difference between the natural and human sciences; despite having seen much positivistic “social science,” which often seems social technology, I believe that there is a difference, but could hardly persuade many easily yet. Through Kuhn I believe I see a way to some solutions. The unit of empirical sociohistorical analysis is the scientific specialty. Units of this sort can be identified through human-scientific approaches such as Kuhn uses, and then how their disciplinary matrices are constituted can be reflectively investigated. I see no reason why this approach would not be just as effective for a technological specialty as for a scientific one and for scientific specialties of the human and formal (e.g., symbolic logic) as much as of the natural sorts. On the basis of empirical findings, free phantasy variation should be able to establish eidetic answers to questions like those mentioned. Given the work of Gurwitsch and Merleau-Ponty in exploiting Gestalt-Psychological results for philosophical purposes (cf. 2 and 3), I do not believe that a phenomenological appreciation of empirical scientific work dealing with intentive life needs to be argued for, at least not in general.

 

 

5. Conclusion

 

Thomas Kuhn is an historian of science who has contrasted old and new scientific, science-historiographic, and science-philosophical images of at least natural science and advocated that science be studied in a multidisciplinary and developmental fashion as a collective human activity somehow related to disciplinary matrices composed of perceived, imagined, believed, valued, and used as well as thought objects. As a constitutive phenomenologist with a felt obligation to reflect on science, I am suggesting that his approach and possibly some of his results are assimilable in principle to my position—in other words, that a constitutive phenomenology of science can benefit from Kuhn’s “pastistic” history of science. Any reflection on science is better if it begins with what science actually has been.
