In addition to thin concepts like the good, the bad and the ugly, our evaluative thought and talk appeals to thick concepts like the lewd and the rude, the selfish and the cruel, the courageous and the kind -- concepts that somehow combine evaluation and non-evaluative description. Thick concepts are almost universally assumed to be inherently evaluative in content, and many philosophers claimed them to have deep and distinctive significance in ethics and metaethics. In this first book-length treatment of thick concepts, Pekka Väyrynen argues that all this is mistaken. Through detailed attention to the language of thick concepts, he defends a novel theory on which the relationship between thick words and evaluation is best explained by general conversational and pragmatic norms. Drawing on general principles in philosophy of language, he argues that many prominent features of thick words and concepts can be explained by general factors that have nothing in particular to do with being evaluative. If evaluation is not essential to the sort of thinking we do with thick concepts, claims for the deep and distinctive significance of the thick are undermined. The Lewd, the Rude and the Nasty is a fresh and innovative treatment of an important topic in moral philosophy and sets a new agenda for future work. It will be essential reading to anyone interested in the analysis and the broader philosophical significance of evaluative and normative language. "Väyrynen presents an extremely well researched, highly innovative, and yet very careful and highly polished treatment of an extremely hot area in philosophy. The book is tightly argued but engagingly written. I would hold it up as a model philosophy monograph. There is no doubt in my mind whatsoever that this book will be widely influential and admired. Indeed, it could easily become a classic." - Brad Hooker, University of Reading "For the past few decades thick concepts have received much attention in metaethical discussions, but Väyrynen's book is the first comprehensive treatment of the subject. Väyrynen skillfully uses tools from philosophy of language in order to sharpen and advance the discussion of thick concepts. The book will be essential reading not only to anyone interested in the specific topic of thick concepts but also to anyone who is concerned with the analysis of normative language generally. It is a very good paradigm of linguistically informed metaethics." - Matti Eklund, Cornell University

In addition to 'thin' concepts like the good, the bad and the ugly, our evaluative thought and talk appeals to 'thick' concepts like the lewd and the rude, the selfish and the cruel, the courageous and the kind - concepts that somehow combine evaluation and nonevaluative description. Thick terms and concepts are almost universally assumed to be inherently evaluative in meaning or content. And many philosophers have claimed them to have deep and distinctive significance for many general issues in moral philosophy, including the distinction between 'facts' and 'values', objectivity in ethics, the possibility of moral theory in traditional style and more. This book argues that all of this is mistaken.

Theorists working on metaethics and the nature of normativity typically study goodness, rightness, what ought to be done, and so on. In their investigations they employ and consider our actual normative concepts. But the actual concepts of goodness, rightness, and what ought to be done are only some of the possible normative concepts there are. There are other possible concepts, ascribing different properties. Matti Eklund explores the consequences of this thought, for example for the debate over normative realism, and for the debate over what it is for concepts and properties to be normative. Conceptual engineering - the project of considering how our concepts can be replaced by better ones - has become a central topic in philosophy. Eklund applies this methodology to central normative concepts and discusses the special complications that arise in this case. For example, since talk of improvement is itself normative, how should we, in the context, understand talk of a concept being better?

The descriptions 'good' and 'bad' are examples of thin concepts, as opposed to 'kind' or 'cruel' which are thick concepts. Simon Kirchin provides one of the first full-length studies of the crucial distinction between 'thin' and 'thick' concepts, which is fundamental to many debates in ethics, aesthetics and epistemology

Many have been attracted to the idea that for something to be good there just have to be reasons to favour it. This view has come to be known as the buck-passing account of value. According to this account, for pleasure to be good there need to be reasons for us to desire and pursue it. Likewise for liberty and equality to be values there have to be reasons for us to promote and preserve them. Extensive discussion has focussed on some of the problems that the buck-passing account faces, such as the 'wrong kind of reason' problem. Less attention, however, has been paid as to why we should accept the buck-passing account or what the theoretical pay-offs and other implications of accepting it are. The Normative and the Evaluative provides the first comprehensive motivation and defence of the buck-passing account of value. Rach Cosker-Rowland argues that the buck-passing account explains several important features of the relationship between reasons and value, as well as the relationship between the different varieties of value, in a way that its competitors do not. He shows that alternatives to the buck-passing account are inconsistent with important views in normative ethics, uninformative, and at odds with the way in which we should see practical and epistemic normativity as related. In addition, he extends the buck-passing account to provide an account of moral properties as well as all other normative and deontic properties and concepts, such as fittingness and 'ought', in terms of reasons.
