Each of these places offered a materially contingent model of cognition, formalizing thought as embedded in, and routed through, materially constructed worlds.44 They are particularly metaphorically rich, spaces which are themselves instantly recognizable as metaphor (sketchbooks and ledgers of accounts, for example) or which are the material rudiments of master metaphors governing other, subordinate metaphors (books, libraries, cabinets). The library, Jennifer Summit notes, has long articulated a problem of knowledge meant to be understood as a basic problem of cognition; the library came to be not a mere sorting and storage unit but a material experiment in experiences of doubt and certainty. Libraries and librarians are in this sense historically and evolutionarily linked in mutually reflexive processes of “sorting, selecting, preparing, and internalizing information”; the library made possible a model of thinking based on the storage, recall, and arrangement of little nuggets of knowledge, differently called facts, information, or ideas.45 The same processes at work in the library might therefore be understood to be at work in the mind, a vocabulary developed among the objects of learning shifted into ways of thinking about intellection generally. Such a space actively enabled the “creative, rather than static” work of memory, providing a model of how a conservative faculty might be made productive.46 And, as the library made possible such a modeling, it responded as well to developments in how the mind was understood, a point made explicitly clear in John Evelyn’s “Method for a Library According to the Intellectual Powers.” Epistemological theory, in this respect, has real consequences for how the world is arranged, and vice versa, a process visible, for instance, in the library of John Locke (Exhibit 1).
Metaphor
The empiricist revolution was not originally a revolution “out there,” as though it were a communal effort to create better rocket fuels or cancer drugs; it was, on the contrary, very much a revolution beginning “in here,” a project of mental discipline, meaning to match conceptual systems to an observable world of things. The central pillar of Bacon’s empiricist program was his effort to establish “in the human intellect … a true pattern of the world as we actually find it and not as someone’s own private reasoning hands it down to him.”47 The language appropriate to this project, as the argument goes, was suspicious of metaphor. The number of new philosophical languages developed in and around the Royal Society attests itself to the importance of matching labels to things, without the slippage introduced when words are made to do double work.48 In thinking about the place of metaphor in the empiricist project, historians of science have been quick to quote such moments as Locke’s eloquent attack on eloquence—where Locke, among other things, derides the use of tropes and figures in the pursuit of truth. And, to the extent that he was generally uncomfortable substituting a more poetic word where a prosaic one would do (his own powerful deployment of images notwithstanding), this is a generally accurate description of the empiricist project. Locke insists, in a much-cited passage, that “all the artificial and figurative application of words eloquence hath invented, are for nothing else but to insinuate wrong ideas, move the passions, and thereby mislead the judgment.”49 In this sense, Locke may be said to be echoing Francis Bacon, John Wilkens, Henry Power, and a host of scholars in the same, ultimately Aristotelian tradition, who were working to transform communication from a medium of persuasion to a medium of transmission, replacing eloquence, in the common formulation, with plain facts.50
Many of the passages in which the plain style is most eloquently defended are, however, themselves promoted by dazzling turns of metaphorical prose. Take, for instance, Robert Boyle’s famous defense of the plain style: “Our design is only to inform Readers,” Boyle insists, “not to delight or perswade them…. To affect needless Rhetorical Ornaments in setting down an Experiment,” he continues, “were little less improper than it were … to paint the Eye-glasses of a Telescope.”51 Understood this way, metaphor would merely be, as Richard Rorty points out, like “using italics, or illustrations, or odd punctuation or formats. All these,” he writes, “are ways of producing effects on your interlocutor or your reader but not ways of conveying a message”;52 they are, in other words, relics of an age where communication was understood to involve rhetorical persuasion rather than the conveyance of a message. This is a keynote of the empiricist project; language in the empiricist mode is meant to be a medium for facts, information, or ideas.53 Yet Boyle’s appeal at the very least adjusts itself through a strikingly posed rhetorical ornament—which Boyle himself surely recognized. Boyle in other words encourages us to be suspicious of metaphor through a suspicious metaphor; he paints his own eyepiece. This is the first way that plain anti-rhetoricality itself leans on a set of rhetorical conventions, indeed encases itself in a rhetorical purpose, for its inbuilt work is after all to persuade.54
Boyle’s deployment of the showy metaphor of the painted eyepiece distracts attention from a different level of metaphorical work, threading its way through his prose.55 The focus on metaphor as a rhetorical choice ignores the more fundamental role that metaphor plays as a coordinating condition, a necessary and irreducible process in the grand project of producing, in the mind, an empirically true pattern of the world. This second form of metaphorical borrowing builds concepts out of bodily intersections with the world—so, for instance, “perswade” means “make sweet,” “inform” means “give shape to,” “delight” leans on the Latin for “attract,” and so on. There are in fact two forms of metaphor to be considered, and distinguished from one another—a point not lost on Boyle’s contemporaries. On the one hand, there is metaphor as a rhetorical substitution of one word or phrase (with all its attendant baggage) for another. This is the painted eyeglass. On the other, there is metaphor as the linkage between material world and ideal pattern, between sensory rudiments and their conceptual wages. This is “perswade,” “inform,” “delight.” The first sort of metaphor has its uses, even in the plain style, though it is met with general distrust. As Locke reminds us, such rhetorical substitution is “fancy passing for knowledge”; “what is prettily said,” Locke elegantly continues, “is taken for solid.”56 But the second sort is a necessary element in the linguistic linking of ideas and things, the guarantee, in fact, that mental work may be traced to a material foundation; it insinuates the central mandate of the empiricist project, to seek knowledge “in the consideration of the things themselves,” into the texture of the medium used to carry out that project.57 What is more, and this is really the critical thing, this second sort of metaphor was witnessed as the critical linkage making possible the construction of a mental reality patterned on the
