In psychiatry there is no sharp boundary between the normal and the pathological. Although clear cases abound, it is often indeterminate whether a particular condition does or does not qualify as a mental disorder. For example, definitions of subthreshold disorders and of the prodromal stages of diseases are notoriously contentious. Philosophers and linguists call concepts that lack sharp boundaries, and thus admit of borderline cases, vague. Although blurred boundaries between the normal and the pathological are a recurrent theme in many publications concerned with the classification of mental disorders, systematic approaches that take into account philosophical reflections on vagueness are rare. This book provides interdisciplinary discussions about vagueness in psychiatry by bringing together scholars from psychiatry, psychology, philosophy, history, and law. It draws together various lines of inquiry into the nature of gradations between mental health and disease and discusses the individual and societal consequences of dealing with blurred boundaries in medical practice, forensic psychiatry, and beyond. Part I starts with an overview chapter that helps readers to navigate through the philosophy of vagueness and through the various debates surrounding demarcation problems in the classification and diagnosis of mental illness. Part II encompasses historical and recent philosophical positions on gradualist approaches to health and disease. Part III approaches the vagueness of present psychiatric classification systems and the debates concerning their revision by scrutinizing controversial categories such as post-traumatic stress disorder and by looking into the difficulties of day-to-day diagnostic and therapeutic practice. Part IV finally focuses on social, moral, and legal implications that arise when being mentally ill is a matter of degree.

Vague expressions are omnipresent in natural language. As such, their use in legal texts is virtually inevitable. If a law contains vague terms, the question whether it applies to a particular case often lacks a clear answer. One of the fundamental pillars of the rule of law is legal certainty. The determinacy of the law enables people to use it as a guide and places judges in the position to decide impartially. Vagueness poses a threat to these ideals. In borderline cases, the law seems to be indeterminate and thus incapable of serving its core rule of law value.In the philosophy of language, vagueness has become one of the hottest topics of the last two decades. Linguists and philosophers have investigated what distinguishes "soritical " vagueness from other kinds of linguistic indeterminacy, such as ambiguity, generality, open texture, and family resemblance concepts. There is a vast literature that discusses the logical, semantic, pragmatic, and epistemic aspects of these phenomena. Legal theory has hitherto paid little attention to the differences between the various kinds of linguistic indeterminacy that are grouped under the heading of "vagueness ", let alone to the various theories that try to account for these phenomena.Bringing together leading scholars working on the topic of vagueness in philosophy and in law, this book fosters a dialogue between philosophers and legal scholars by examining how philosophers conceive vagueness in law from their theoretical perspective and how legal theorists make use of philosophical theories of vagueness. The chapters of the book are organized into three parts. The first part addresses the import of different theories of vagueness for the law, referring to a wide range of theories from supervaluationist to contextualist and semantic realist accounts in order to address the question of whether the law can learn from engaging with philosophical discussions of vagueness. The second part of the book examines different vagueness phenomena. The contributions in part 2 suggest that the greater awareness to different vagueness phenomena can make lawyers aware of specific issues and solutions so far overlooked. The third part deals with the pragmatic aspects of vagueness in law, providing answers to the question of how to deal with vagueness in law and with the professional, political, moral, and ethical issues such vagueness gives rise to.

This is the first collection of essays devoted specifically to the nature and significance of Aristotle's anthropological philosophy, covering the full range of his ethical, metaphysical and biological works. The book is organised into four parts, two of which deal with the metaphysics and biology of human nature and two of which discuss the anthropological foundations and implications of Aristotle's ethico-political works. The essay topics range from human nature and morality to friendship and politics, including original discussion and fresh perspectives on rationalism, the intellect, perception, virtue, the faculty of speech and the differences and similarities between human and non-human animals. Wide-ranging and innovative, the volume will be highly relevant for readers studying Aristotle as well as for anyone working on either ancient or contemporary philosophical anthropology.
