Are images an important means of recalling information from memory and solving problems? Or are images just display lights on the mind’s computer? In Image and Mind, Stephen Kosslyn makes an impressive case for the view that images are critically involved in the life of the mind. In a series of ingenious experiments, he provides hard evidence that people can construct elaborate mental images, search them for specific information, and perform such other internal operations as mental rotation. Kosslyn demonstrates that these results are best explained by a two-tiered model in which images are stored in abstract form in long-term memory and then assembled for internal display in much the way that images on a TV screen can be created from files in a computer memory.

Kosslyn shows how this model can be used to solve many of the persistent questions which have traditionally plagued theories of imagery that attempted to install imagery as the exclusive medium of mental representation.

Unlike any other work on imagery, Image and Mind provides an integrated account of most of the modern empirical results from imagery research within the framework of a coherent theory. The book also introduces a host of new experimental techniques and major hypotheses to guide future research. The result is a landmark book and a major event in the study of the mind.

Nineteenth-century chemists were faced with a particular problem: how to depict the atoms and molecules that are beyond the direct reach of our bodily senses. In visualizing this microworld, these scientists were the first to move beyond high-level philosophical speculations regarding the unseen. In Image and Reality, Alan Rocke focuses on the community of organic chemists in Germany to provide the basis for a fuller understanding of the nature of scientific creativity. 

Arguing that visual mental images regularly assisted many of these scientists in thinking through old problems and new possibilities, Rocke uses a variety of sources, including private correspondence, diagrams and illustrations, scientific papers, and public statements, to investigate their ability to not only imagine the invisibly tiny atoms and molecules upon which they operated daily, but to build detailed and empirically based pictures of how all of the atoms in complicated molecules were interconnected. These portrayals of “chemical structures,” both as mental images and as paper tools, gradually became an accepted part of science during these years and are now regarded as one of the central defining features of chemistry.  In telling this fascinating story in a manner accessible to the lay reader, Rocke also suggests that imagistic thinking is often at the heart of creative thinking in all fields.

Image and Reality is the first book in the Synthesis series, a series in the history of chemistry, broadly construed, edited by Angela N. H. Creager, John E. Lesch, Stuart W. Leslie, Lawrence M. Principe, Alan Rocke, E.C. Spary, and Audra J. Wolfe, in partnership with the Chemical Heritage Foundation.
