systems of metaphors that refer to embodied experience. Metaphor is the crucial route by which mind is made sensible; it is how a vocabulary and way of speaking is worked up in order to make the mind available to itself. It will become apparent, therefore, that this dazzling accomplishment, the work of an age to disengage mind from materials, came through a counterintuitive embeddedness. Theories of a mind separate from matter were repeatedly developed by tinkering with physical gadgets; the sovereign intellect was constructed in and shored up through dialectical relationships between persons and the places in which they lived and worked. This is the basic claim of this book, so it bears repeating. The doctrine of radical separation was elaborated through a series of profound entanglements: subjects entangled with objects, owners with property, awareness with memory, the power of thinking with thoughts, conscious awareness with the mind’s contents. Put simply, the fundamental split between mind and matter was established and confirmed through embodied engagement with crafted environments.
This to-and-fro between models and minds, spaces of thinking and habits of thought, is what this book will mean by cognitive ecologies. A cognitive ecology is a system crafted to enable certain kinds of thinking, indeed, to confirm and to conform to a specific working theory of mind. Libraries count; so do workshops, notebooks, and collections. Museums offer the paradigmatic example—for a “museum” is nothing other than an active space of thinking, the favored seat of the muses. The age is littered with people modeling their intellect on the spaces in which they worked. John Locke says the mind is like a cabinet; Joseph Addison compares it to a drawer of medals; Francis Bacon calls it a repository; Robert Hooke calls it a workshop. The thing to notice is this: Locke was a bibliophile, Addison a coin collector, Bacon an architect of libraries, Hooke a laboratory technician. The faculties and capacities of the minds that were invented there are roughly equivalent to what we might expect from any librarian in a library, conservator in a numismatic collection, curator in a museum, or artisan in a workshop—because each space provided the vocabulary for the theory in the first place. And this means that philosophical dualisms have histories that are not confined to histories of ideas; their histories spread out into the material, cultural, and political beds in which they find themselves. We should, in other words, attend to Locke’s cabinet, Addison’s medals, Bacon’s repository, and Hooke’s workshop, not as curiosities of museology, but as histories of ideas. These were the sites where the museum metaphor of mind was worked out in all its rigor. And they were also sites of profound entanglements, where conceptual systems were continually, dialectically returned for their material purchase and rhetorical force.
The Mind Is a Collection offers an ecology of such ecologies. It is arranged as a series of case studies, forming an argument through the elaborations of objects in place, particular objects in the particular cases in which they were once found. “Case” is a term that will receive more attention in its place (Exhibit 16); for now it is enough to note that it means to capture two things at once. It means to signify the spaces in which thinking takes place—a room, a cabinet, the skin, the skull. “Case” in this sense is the sort of thing one might find in a museum, a thing custom built to display objects or books (exhibit cases, book cases, and so on). But “case” also, as Ludwig Wittgenstein puts it, means to capture the whole world or situation that is implied by something as small as a statement or local relation: “the world,” Wittgenstein begins, is “all that is the case.” A legal case is defined by the slightest of evidence; a medical case is decided by the merest of symptoms. Partly, tracing these case studies will mean a wander or two through philosophy, especially in the empiricist legacy of John Locke. It will mean more than a few journeys through the so-called sister arts, curatorial forms like poetry, painting, and architecture. Each of these, it will appear, was imagined as the confirmation of a mind that works by arranging ideas. But it also means a renewed attention to active objects of thought; the material arrangements of things that were developed and then cast aside so as to launch the Enlightenment figure of the autonomous mind. The Mind Is a Collection brings to life a few of the collections left behind by this historical development, cognitive models that were used to separate cognitive activity from bodily work. And I should mention that by no means is this study the first to think of thinking as an embedded practice, or even of empiricist thought as itself arising from its various situations; John Locke, among others, was himself invested in the links between thinking and tinkering, mental discipline and the library arts. In other words, some of the very people we most commonly associate with the distinction between body and mind were also the earliest theorists of cognition as an embedded practice. This is why The Mind Is a Collection begins with the library and commonplace book of John Locke (Exhibit 1).
The following twenty-eight exhibits provide the fabric of an argument. They trace epistemic dualism as an intimately felt experience and a philosophical belief. They do not exhaust the topic. How could they? Particulars are like that; more can always be found, and the ones we have are never enough. These twenty-eight exhibits offer the merest trajectory or constellation, objects as points suggesting a larger picture of Enlightenment being. At the same time, if more can always be found, one never has quite the right ones. The particularity, even idiosyncrasy, of the objects in this collection is one of the many ways that gaps and cracks will be felt, emerging precisely in the imperfect fit of things one to another. I myself spent many years as a furniture maker, what in the tradecraft lingo is called a “joiner.” Mortise-and-tenon, dovetail, bridle, and key joints: my whole job was the seamless fit of one piece of wood to another. Nothing disturbed me more than a gap. And as a joiner, I had the luxury of not having to accept the rough fit of things. But the task of a curator is different; as a curator, you work with what you have got. You care for things, in all their irreducible particularity. Gaps are the frustration and promise of the labor. In telling the story of the rise of theories of the sovereign intellect, in proposing to recast this story in the concrete stuff its manufacture left behind, this museum will concentrate much of its attention on the craft of a few familiar figures. There will be, I trust, at least a few unexpected ecologies represented here—but in general the first twenty-two exhibits mean to undo the familiar account of mind over matter by concentrating precisely on its most familiar champions. The final six final exhibits are however different. These are asked to provide the conceptual weight to balance the museum’s first twenty-two, indeed to call into question the fundamental assumptions of possessive individuals by unpacking the textures of dispossession. In this sense, these six are the most important—and the least adequate to the burden they are made to bear. So, the seams will show—which is another way of saying that much work remains to be done. If I had it to do over, I would have lavished more labor in finding objects fit for telling this other story—the story of the dispossessed. But since I only discovered these precarious things through the archives of modern philosophy’s more familiar champions, I’m afraid these six exhibits will have to make the case by themselves.
As someone who cares for all these things—a “curator” in the word’s original sense—I would ask you, as you read this book, to think of it like the virtual museum to which it refers. Like any caretaker, I invite you to wander. Please feel free to move quickly through some sections, seek out the ones of most interest to you, skip others altogether. Leave for coffee and return; your ticket is good for multiple entries. But, like any museum, this book also aims for a certain representative scope. As its curator, I flatter myself that it has a total story to tell—an argumentative arc intended to emerge implicitly through examples. I am tempted to say that the exhibits in this museum have been arranged according to the confidence with which they were owned. From Exhibit 1, the cognitive ecology of the architect of possessive individualism, to Exhibit 28, an object special to a man who wedged himself between possessions and individuals, The Mind Is a Collection passes from habits of ownership to patterns of dispossession. But this gets it backward; it is better to say that the museum passes from authors most confident in the systems they construct, to ecologies most attentive to the dynamic nature of embedded thought. The book means to turn possession inside out, moving from the confident possessors of things to people living wide-eyed in the shifting marketplace of mental materials. As one form of authority recedes, the empire of things begins to emerge. By the time you reach the gift shop, this museum hopes to have emptied out possession as a meaningful way of thinking about
