Philosophers of science work not only with the methods of the sciences but with their contents as well. Substantive issues concerning the relation between mind and matter, between the material basis and the functions of cognition, have been central within the entire history of philosophy. We recall such philosophers as Aristotle, Descartes, the early Kant, Ernst Mach, and the early William James as directly inquiring of the organs and structures of thinking. Science and its philosophical self-criticism are especially and deeply united in the effort to understand the biological brain and human behavior, and so it requires no apology to include this collection of clinical studies among Boston Studies in the Philosophy of Science. The work of Dr. Norman Geschwind, well represented in this selection, explores the relation between structure and function, between the anatomy of the brain and the 'higher' behavior of men and women. As a clinical neurologist, Geschwind was led to these studies particularly by his in terest in those pathologies which have to do with human perception and language. His research into the anatomical substrates of specific dis orders-and strikingly the aphasias -present a fascinating and provocative examination of fundamental questions which will concern not neurologists alone but also psychologists, physicians, linguists, speech pathologists, educators, anthropologists, historians of medicine, and philosophers, among others, namely all those interested in the characteristic modes of human activity, in speech, in perception, and in the learning process generally.

In the mid-nineteenth century, physicians observed numerous cases in which individuals lost the ability to form spoken words, even as they remained sane and healthy in most other ways. By studying this condition, which came to be known as "aphasia," neurologists were able to show that functions of mind were rooted in localized areas of the brain. Here L. S. Jacyna analyzes medical writings on aphasia to illuminate modern scientific discourse on the relations between language and the brain, from the very beginnings of this discussion through World War I. Viewing these texts as literature--complete with guiding metaphors and rhetorical strategies--Jacyna reveals the power they exerted on the ways in which the human subject was constructed in medicine. Jacyna submits the medical texts to various critical readings and provides a review of the pictorial representation involved with the creation of aphasiology. He considers the scientific, experimental, and clinical aspects of this new field, together with the cultural, professional, and political dimensions of what would become the authoritative discourse about language and the brain. At the core of the study is an inquiry into the processes whereby men and women suffering from language loss were transformed into the "aphasic," an entity amenable to scientific scrutiny and capable of yielding insights about the fundamental workings of the brain. But what became of the subject's human identity? Lost Words explores the links among language, humanity, and mental presence that make the aphasiological project one of continuing fascination.

"Aphasia and Related Neurogenic Communication Disorders is designed for the graduate course on Aphasia. Part 1 of the textbook covers aphasiology, while part 2 addresses related disorders. Overall, the textbook offers an overview of aphasia and related neurogenic communication disorders by presenting important recent advances and clinically relevant information. It emphasizes Evidence Based Practice by critically reviewing the pertinent literature and its relevance for best clinical practices. Case studies in all clinical chapters illustrate key topics, and a "Future Directions" section in each chapter provides insight on where the field may be headed. The WHO ICF Framework is introduced in the beginning of the text and then reinforced and infused throughout"--
