Originally published in 1993, this monograph addresses a central problem in Piaget’s work, which is the temporal construction of necessary knowledge. The main argument is that both normative and empirical issues are relevant to a minimally adequate account of the development of modal understanding. This central argument embodies three main claims. One claim is philosophical. Although the concepts of knowledge and necessity are problematic, there is sufficient agreement about their core elements due to the fundamental difference between truth-value and modality. Any account of human rationality has to respect this distinction. The second claim is that this normative distinction is not always respected in psychological research on the origins of knowledge where emphasis is placed on the procedures and methods used to gain good empirical evidence. An account of the initial acquisition of knowledge is not thereby an account of its legitimation in the human mind. The third claim relates to epistemology. Intellectual development is a process in which available knowledge is used in the construction of better knowledge. The monograph identifies features of a modal model of intellectual construction, whereby some form of necessary knowledge is always used. Intellectual development occurs as the reduction of modal errors through the differentiation and coordination of available forms of modal understanding. Piaget’s work continues to provide distinctive and intelligible answers to a substantive and outstanding problem.

In response to a request by the Health Care Financing Administration (HCFA), the Institute of Medicine proposed a study to examine definitions of serious or complex medical conditions and related issues. A seven-member committee was appointed to address these issues. Throughout the course of this study, the committee has been aware of the fact that the topic addressed by this report concerns one of the most critical issues confronting HCFA, health care plans and providers, and patients today. The Medicare+Choice regulations focus on the most vulnerable populations in need of medical care and other services-those with serious or complex medical conditions. Caring for these highly vulnerable populations poses a number of challenges. The committee believes, however, that the current state of clinical and research literature does not adequately address all of the challenges and issues relevant to the identification and care of these patients.

This is a comprehensive, state-of-the-art guide to the diagnosis, treatment, and biology of multiple myeloma and related plasma disorders. Edited and written by a multidisciplinary group of recognized authorities from the Mayo Clinic, it presents clear guidelines on diagnosis and therapy and covers all aspects of multiple myeloma, from molecular classification and diagnosis, to risk stratification and therapy. Closely related plasma cell disorders such as solitary plasmacytoma, Waldenstrom macroglobulinemia, and light chain amyloidosis are discussed in detail as well. The book addresses often overlooked topics, including the role of radiation therapy, vertebral augmentation, and supportive care. Our understanding of this group of disorders is developing at an unprecedented rate, and Multiple Myeloma meets the need among oncologists and hematologists for a clear, timely, and authoritative resource on their biology, diagnosis, and treatment.

Critical Readings on Piaget is a follow-up to Piaget: Critical Assessments a collection of eighty-three papers dealing with the critique of Piaget's work in psychology, education and philosophy during the period 1950-90. This new collection tracks developments in the most recent published work during the period 1990-95, with an integral guide and editorial commentary by Leslie Smith. Starting with Piaget's epistemology, a major intellectual resource in departmental psychology and eduction, Leslie Smith sets out the main elements of Piaget's position in relation to twenty one papers, dealing with equilibration and equilibrium, education and social development, reasoning development, number development and modal knowledge. A conclusion examines the psychological and educational assessment of Piaget's epistemology. This collection of distinctive studies during the last five years provides high-profile and engaging examples from current research in this area. It will provide a useful and compact text for undergraduate and postgraduate students and researchers.

Wittgenstein: Meaning and Mind is the third volume of a four-volume analytical commentary on Wittgenstein's Philosophical Investigations, consisting of two parts. Part 1 is a sequence of fifteen essays that examine in detail all the major topics discussed in Philosophical Investigations §§243-427. These include the private language arguments, privacy, private ostensive definition, the nature of the mind, the inner and the outer, behaviour and behaviourism, thought, imagination, the self, consciousness, and criteria. Published in 1990 to widespread acclaim as a scholarly tour de force, the first edition of this volume of essays provides a comprehensive survey of these themes, the history of their treatment in early modern and modern philosophy, the development of Wittgenstein's ideas on these subjects from 1929 onwards, and an elaborate analysis of his definitive arguments in the Investigations. The new second edition has been thoroughly revised by the author and features four new essays. These include a survey of the evolution of the private language arguments in Wittgenstein's oeuvre and their role within the developing argument of the Investigations, a comprehensive essay on private ownership of experience and its pitfalls, a detailed examination and defence of Wittgenstein's repudiation of subjective knowledge of one's experience, and an overview of the achievement and importance of the private language arguments. Revised essays examine new objections to Wittgenstein's arguments – which are found wanting– and incorporate new materials from the Nachlass that were not known to exist in 1990. All references have been adjusted to the revised fourth edition of the Investigations, but previous pagination in the first and second editions has been retained in parentheses. These revisions bring the book up to the high standard of the extensively revised editions of Wittgenstein: Understanding and Meaning (Blackwell, 2005) and Wittgenstein: Rules, Grammar and Necessity (Wiley Blackwell, 2009). They ensure that this survey of Wittgenstein's private language arguments and of his accounts of thought, imagination, consciousness, the self, and criteria will remain the essential reference work on the Investigations for the foreseeable future.
