Virtual Witnessing and the Role of the Reader in a New Natural Philosophy

How did the self-described new natural philosophies of the early modern period displace other philosophic (moral, ethical, legal), and specifically religious, discourses as the locus of truth in our culture? Natural philosophy's rejection of disputation and of revelation as means of producing truth in favor of the "discovery" of truth was more accurately an introduction of the invention of truth than of its discovery, and this invention demanded the creation of and participation of a certain kind of reader. Rhetorical examination of the early modern magnetic philosopher William Gilbert's most influential work, De Magnete, ¹ will help us understand the "paradigm change," to use Thomas Kuhn's oft-misquoted term, ² from a culture that accepted probabilistic truth in the natural realm to one that expected moral certainty, from a culture that accepted revelation as a legitimate means of access to truth to one that increasingly recognized only the "discovery" of truth through sensual experience disciplined through experiment.

One way this paradigm change was effected was through the inclusion of the reader as an active participant in the new natural philosophies. The reader was included in the new natural philosophies by engendering in him desires for particular forms of knowledge and particular ways of attaining that knowledge. Peter Dear notes that "in the seventeenth century old practices changed and new ones appeared. Those changing practices represent shifts in the meaning of experience itself" (12-13), and he then asks the question that might well have been on the tongues of many as the old practices gave way to the new: "how can a universal knowledge-claim about the natural world be justified on the basis of singular items of individual experience?" (13). A crucially important way to justify the universal knowledge-claim on singular items of individual experience was through the employment of a technique Steven Shapin and Simon Schaffer have labeled "virtual witnessing" (60-65). Briefly, "virtual witnessing" describes the use of linguistic resources to produce a vicarious experience enabling a reader to confer agreement as though she had actually been present when an experiment was conducted. Virtual witnessing alone, however, cannot explain how the scientific became the dominant truth-producing paradigm in our culture. Virtual witnessing intermingled with a variety of other elements in early modern natural philosophy to encourage readers to participate in the invention of "true" accounts of the world in which we live. In this article I will apply the tools of rhetorical analysis as I use the example of De Magnete to elaborate on how a Foucauldian form of disciplinary impulse combined in the early modern period with the technology of virtual witnessing to create an audience inculcated with desire, interest, and belief in the new natural philosophy, which had to precede and accompany expansion of the scientific into the dominant truth-producing paradigm it has long since become.

For the sake of clarity I should expound upon the two key elements of my argument, "discipline," in the Foucauldian sense in which I use the term, and "virtual witnessing." According to Michel Foucault, "discipline" is "a political anatomy of detail . . . situated on the axis that links the singular and the multiple" (139-49), and I argue that this point, on the "axis that links the singular and the multiple," is exactly the point that enables modern science. William Gilbert's De Magnete can help us understand how knowledge and power--or epistemê and technê, to use another, perhaps more rhetorically inflected, vocabulary--combined in the early modern period to produce the effects that would become those of modern science. Gilbert provides an excellent example of the movement from the production of truth through revelation to the production of truth through discovery and the experimental method. De Magnete persuades its reader by rendering visible a formerly invisible "universal nature," ³ so that truth is no longer warranted by the invisible workings...
