The goal of the present volume is to discuss the notion of a 'conceptual framework' or 'conceptual scheme', which has been dominating much work in the analysis and justification of knowledge in recent years. More specifi cally, this volume is designed to clarify the contrast between two competing approaches in the area of problems indicated by this notion: On the one hand, we have the conviction, underlying much present-day work in the philosophy of science, that the best we can hope for in the justifi cation of empirical knowledge is to reconstruct the conceptual means actually employed by science, and to develop suitable models for analyzing conceptual change involved in the progress of science. This view involves the assumption that we should stop taking foundational questions of epistemology seriously and discard once and for all the quest for uncontrovertible truth. The result ing program of justifying epistemic claims by subsequently describing patterns of inferentially connected concepts as they are at work in actual science is closely connected with the idea of naturalizing epistemology, with concep tual relativism, and with a pragmatic interpretation of knowledge. On the other hand, recent epistemology tends to claim that no subsequent reconstruction of actually employed conceptual frameworks is sufficient for providing epistemic justification for our beliefs about the world. This second claim tries to resist the naturalistic and pragmatic approach to epistemology and insists on taking the epistemological sceptic seriously."

This book is the fruit of a study group on perception and action that worked at the Center for Interdisciplinary Research (ZiP) of the University of Bielefeld, FRG in the academic year 1984-1985. We express our gratitude to the ZiF for hosting the group and for providing fmancial and organizational support for its scientific activities, including a meeting of the authors of the present volume that took place at the ZiF in July 1986. This is/ the study group's last common product, and it took considerable time to give the book its fmal shape. Most of the editing was done while one of us (0. N.) was a Fellow at the Netherlands Institute for Advanced Study in the Humanities and Social Sciences (NlAS) during the academic year 1987-1988. Thanks are due to NIAS for its generous support. We also thank all our friends and colleagues who contributed to the book.

Dignity is humanity's most prized possession. We experience the loss of dignity as a terrible humiliation: when we lose our dignity we feel deprived of something without which life no longer seems worth living. But what exactly is this trait that we value so highly? In this important new book, distinguished philosopher Peter Bieri looks afresh at the notion of human dignity. In contrast to most traditional views, he argues that dignity is not an innate quality of human beings or a right that we possess by virtue of being human. Rather, dignity is a certain way to lead one's life. It is a pattern of thought, experience and action in other words, a way of living. In Bieri's account, there are three key dimensions to dignity as a way of living. The first is the way I am treated by others: they can treat me in a way that leaves my dignity intact or they can destroy my dignity. The second dimension concerns the way that I treat other people: do I treat them in a way that allows me to live a dignified life? The third dimension concerns the view that I have of myself: which ways of seeing and treating myself allow me to maintain a sense of dignity? In the actual flow of day-to-day life these three dimensions of dignity are often interwoven, and this accounts in part for the complexity of the situations and experiences in which our dignity is at stake. So, why did we invent dignity and what role does it play in our lives? As thinking and acting beings, our lives are fragile and constantly under threat. A dignified way of living, argues Bieri, is humanity's way of coping with this threat. In our constantly endangered lives, it is important to stand our ground with confidence. Thus a dignified way of living is not any way of living: it is a particular way of responding to the existential experience of being under threat. It is also a particular way of answering the question: What kind of life do we wish to live? This beautifully written reflection on our most cherished human value will be of interest to a wide readership.
