ArgumentA growing cross-disciplinary literature has acknowledged the importance of verbal-visual interaction in the creation and communication of scientific texts. I contend that the proper understanding of these texts must flow from a hermeneutic model that takes verbal-visual interaction seriously, one that is firmly grounded in cognitive constraints and affordances. The model I propose has two modules, one for perception, derived from Gestalt psychology, the other for cognition, derived from Peirce's semiotics. I apply this model to an important but largely neglected text in the history of nineteenth-century science, Charles Lyell'sThe Geological Evidences of the Antiquity of Man, and to two accounts by well-respected historians of science, both of the same key discovery in quantum physics. In doing so, I hope to demonstrate the advisability of incorporating the exegetical practices my model entails into the everyday practices of historians of science.

In lieu of an abstract, here is a brief excerpt of the content:Philosophy and Rhetoric 33.4 (2000) 319-335 [Access article in PDF] Rhetoric as a Technique and a Mode of Truth: Reflections on Chaïm Perelman Alan Gross In memoriam: Henry Johnstone, fons et origo.In one of his many criticisms of The New Rhetoric, the philosopher Henry W. Johnstone Jr. complains about its chapter "The Dissociation of Concepts" that "one is never sure whether [Chaïm Perelman is] thinking of rhetoric primarily as a technique or primarily as a mode of truth. One wonders, too, what status [he is] claiming for the book itself" (1978, 99). 1 Since the chapter in question largely concerns philosophical argument, the doubt is very much apropos. But the response to Johnstone's implied question--a response that Johnstone does not think available--is that the correct answer legitimately varies in a systematic way. While in philosophical contexts, and, incidentally, in scientific ones, rhetoric is invariably a mode of truth, in contexts of public address it need not be. To see how this systematic variation might be the case, I will focus, as does Johnstone, on the dissociation of concepts as a test case of the robustness of a rhetoric oriented toward truth. To do so, I must first define dissociation and then come to terms with the way in which concepts are dissociated in public address, in philosophy, and in science. In treating these examples, however, I must be wary. While they will vary systematically according to field, they are not each instances of any general "law" of dissociation. Johnstone is surely right to "doubt whether there is any general logic of dissociation; there is only the logic of each particular dissociation, generated in each case by a particular problem" (99). When I have run through my examples, I can return to Johnstone's question about the status of rhetoric and of Perelman's study of it.Suppose that, in a campaign for the United States Senate, my opponent says that the central issue is high taxes, not the rise of medical costs, while I say that the central issue is medical costs, not high taxes. Neither of us [End Page 319] need be engaged in the dissociation of concepts; we may simply be excluding taxes and medical care, respectively, from political matters that deserve our immediate and full attention; we may simply be breaking the link between these issues and those of high political salience. In Perelman's words, "[T]he technique of breaking up a liaison consists... in asserting that elements that should remain separated and independent are improperly associated" (Perelman and Olbrechts-Tyteca 1969, 411). Yet, if we think that adequate medical care for all Americans is a moral issue, that it transcends politics, we are dissociating this issue from the category of campaign issues of the ordinary sort, those that deal "merely" with expediency. In the process, we are devaluing matters of mere expediency. Dissociation is a way of taking the argumentative high ground, of putting an issue on a different plane, an act that in this case turns a political race into a moral contest. In Perelman's words, "[T]he dissociation of notions brings about a more or less profound change in the conceptual data that are used as a basis of argument. It is then no more a question of breaking the links that join independent elements, but of modifying the very structure of these elements" (412).To illustrate this difference, I will use two parallel passages on the same topic: one from Stephen Douglas and the other from Abraham Lincoln, both from the debate between them in Alton, Illinois, on 15 October 1858. In his passage, Douglas stoutly defends states' rights: This government was made on the great basis of the sovereignty of the States--the right of each state to regulate its own domestic institutions to suit itself, and that right was conferred with the understanding and expectation that inasmuch as each locality had separate and distinct interests, each state must have different and distinct local and domestic institutions, corresponding to the wants...

The ArgumentConflicts between scientists over credit for their discoveries are conflicts, not merely in, but of science because discovery is not a historical event, but a retrospective social judgment. There is no objective moment of discovery; rather, discovery is established by means of a hermeneutics, a way of reading scientific articles. The priority conflict between Roger Guillemin and Andrew Schally over the discovery of the brain hormone, TRF, serves as an example. The work of Robert Merton, Thomas Kuhn, Augustine Brannigan, and Grygory Markus shows that scientists read scientific articles by means of the application of a set of pragmatic rules that subtend the normative requirements of what counts as a scientific discovery. In other words, there is a hermeneutics of science, but it is internal to that form of life. Recategorization of priority conflicts has an impact on our view of scientific controversy generally. The impact is the revision of the boundary lines of scientific controversy and the further specification of its fine-structure.

In lieu of an abstract, here is a brief excerpt of the content:Rhetoric, Narrative, and the Lifeworld: The Construction of Collective IdentityAlan G. GrossAt the beginning of King Lear, at the point of ceding his throne to his three daughters, Lear asks each for a public acknowledgment of her love. Goneril and Regan flatter their father with effusive declarations, but Lear’s youngest, and his favorite, Cordelia, refuses to do so:I love your Majesty According to my bond; no more or less...................... Good my lord, You have begot me, bred me, lov’d me; I Return those duties back as are right fit, Obey you, love you, and most honour you. Why have my sisters husbands, if they say They love you all? Haply, when I shall wed, That lord whose hand must take my plight shall carry Half my love with him, half my care and duty. Sure I shall never marry like my sisters, To love my father all.(1936, 1.1.94–107) [End Page 118]Furious, Lear disinherits his daughter.Cordelia’s speech is remarkable only in its articulation of what Lear should have known; its dramatic impact is a consequence of Lear’s reaction to his daughter’s argument for divided loyalty that is based on a string of commonplaces that are part of the lifeworld that Lear and his daughter—and every other person in the play—inhabit. Any part of this lifeworld may be thematized, of course; it may be brought out into the open as a topic of discussion. That is what Cordelia does; under duress, she shifts from what Jürgen Habermas calls communicative action to a level he calls discourse, a level that reveals the relationship between the personal and the social as well as their underlying cultural presuppositions. Because Lear refuses to grasp the obvious, the narrative progress of the play is temporarily interrupted and permanently veers off course. Although on occasion we can thematize aspects of our lifeworld, the lifeworld as a whole cannot be subject to scrutiny; it is the totality of certainties, skills, practices, and interpretative frames that we take for granted as we each find our way in the everyday worlds that form the changing horizons of our experience. I take it for granted that too many cooks spoil the broth; telephoning is a skill I do not puzzle over; waiting patiently in line is a social behavior I practice without thinking; with no special effort, I interpret the intimacy of a couple’s relationship by the way they publicly behave toward each other.The lifeworld, a concept initiated by Edmund Husserl and elaborated by Alfred Schütz, Martin Heidegger, and Jürgen Habermas, has been largely neglected by rhetorical theorists and critics. It is the purpose of this paper to show that remedying this neglect opens up fruitful avenues of critical practice and theory. I proceed, first, by defining the lifeworld. Next, I shift perspectives: I analyze how collectivities make sense of their lives by telling stories about themselves grounded in their lifeworld values. It is in the lifeworld’s role in storytelling that, I claim, Aristotle’s Rhetoric becomes an important part of the picture. This is because the Rhetoric is, at bottom, a theory of the way lifeworld values enter into the public sphere. This characterization of the Rhetoric permits us to reconcile two important instantiations of the lifeworld, Habermas’s and Aristotle’s, a reconciliation in which communicative action becomes a special case of rhetorical interaction. Finally, from the perspective of the lifeworld, I reflect on the significance of an exemplary case of the construction of collective identity, the Selma march. [End Page 119]Defining the LifeworldEdmund Husserl’s The Crisis of the European Sciences contains the first explicit philosophical analysis of the lifeworld as “the world that is constantly pregiven, valid constantly and in advance as existing.... Every end presupposes it; even the universal end of knowing it in scientific truth presupposes it, and in advance” (1970, 382). Because the lifeworld is presupposed in everyday communication, it can be entered only by disciplined reflection: “Contemplation is privileged to the extent that it reveals the structures of the world and has them as theme” (1973, 65). Although the lifeworld...

ArgumentHeidegger's philosophy of science is notable for the prominence it gives to visuals and visualization. This is because for Heidegger, truth – including scientific truth – is the consequence of unconcealment, the lifting of a veil. But as scientific truth is a special kind, its visualization is also special: scientific truth reveals itself to us as, in Heidegger's words, “a calculable nexus of forces.” This nexus unconceals itself largely by means of instrumentation: it is this process of revelation that turns objects into objects of science. Despite its focus on visualization, however, Heidegger's philosophy of science cannot be applied directly to scientific visuals. His categories are not designed with visual exegesis in mind. For that purpose, semiotics, the science of meaning as defined by Charles Peirce, is a necessary intermediary between the abstract and the concrete, a taxonomy of icon, index, and symbol that can be employed as a set of hermeneutic probes that permit the exploration of scientific visuals as embodiments and carriers of scientific meaning. But not their sole embodiments and carriers. In achieving scientific semiosis, the verbal and visual must combine their particular strengths. This is also in accord with a Heideggerian view: science moves methodically from the visual to the propositional, though it never leaves the visual behind.

Next, I show that its critique is possible within the confines of his theory by recourse to a minimalist concept of rationality and a version of the truth that avoids the unwelcome metaphysical baggage of truth with a capital T. For critique to be complete, however, it must be supplemented by the full range of rhetorical proofs. Even so, there are limits to the power of critique. In the end, only social and political action can alter oppressive institutional arrangements
