his first chapter, on metaphor, to the last one, on dispossession, Sean Silver looks at ways that abstract theories referred to cognitive ecologies—systems crafted to enable certain kinds of thinking, such as libraries, workshops, notebooks, collections, and gardens. In doing so, he demonstrates the crossings-over of material into ideal, ideal into material, and the ways in which an idea might repeatedly turn up in an object, or a range of objects might repeatedly stand for an idea. A brief conclusion examines the afterlife of the metaphor of mind as collection, as it turns up in present-day cognitive studies. Modern cognitive theory has been applied to the microcomputer, and while the object is new, the habit is as old as the Enlightenment. By examining lived environments and embodied habits from 1660 to 1800, Silver demonstrates that the philosophical dualism that separated mind from body and idea from thing was inextricably established through active engagement with crafted ecologies. |
