Incommensurability is the impossibility to determine how two options relate to each other in terms of conventional comparative relations. This book features new research on incommensurability from philosophers who have shaped the field into what it is today, including John Broome, Ruth Chang and Wlodek Rabinowicz. The book covers four aspects relating to incommensurability. In the first part, the contributors synthesize research on the competing views of how to best explain incommensurability. Part II illustrates how incommensurability can help us deal with seemingly insurmountable problems in ethical theory and population ethics. The contributors address the Repugnant Conclusion, the Mere Addition Paradox and so-called Spectrum Arguments. The chapters in Part III outline and summarize problems caused by incommensurability for decision theory. Finally, Part IV tackles topics related to risk, uncertainty and incommensurability. Value Incommensurability: Ethics, Risk, and Decision-Making will be of interest to researchers and advanced students working in ethical theory, decision theory, action theory, and philosophy of economics.

Can quite different values be rationally weighed against one another? Can the value of one thing always be ranked as greater than, equal to, or less than the value of something else? If the answer to these questions is no, then in what areas do we find commensurability and comparability unavailable? And what are the implications for moral and legal decision making? This book struggles with these questions, and arrives at distinctly different answers."

Value theory, or axiology, looks at what things are good or bad, how good or bad they are, and, most fundamentally, what it is for a thing to be good or bad. Questions about value and about what is valuable are important to moral philosophers, since most moral theories hold that we ought to promote the good (even if this is not the only thing we ought to do). This Handbook focuses on value theory as it pertains to ethics, broadly construed, and provides a comprehensive overview of contemporary debates pertaining not only to philosophy but also to other disciplines-most notably, political theory and economics. The Handbook's twenty-two newly commissioned chapters are divided into three parts. Part I: Foundations concerns fundamental and interrelated issues about the nature of value and distinctions between kinds of value. Part II: Structure concerns formal properties of value that bear on the possibilities of measuring and comparing value. Part III: Extensions, finally, considers specific topics, ranging from health to freedom, where questions of value figure prominently.

Value pluralism is the idea, most prominently endorsed by Isaiah Berlin, that fundamental human values are universal, plural, conflicting, and incommensurable with one another. Incommensurability is the key component of pluralism, undermining familiar monist philosophies such as utilitarianism. But if values are incommensurable, how do we decide between them when they conflict? George Crowder assesses a range of responses to this problem proposed by Berlin and developed by his successors. Three broad approaches are especially important: universalism, contextualism, and conceptualism. Crowder argues that the conceptual approach is the most fruitful, yielding norms of value diversity, personal autonomy, and inclusive democracy. Historical context must also be taken into account. Together these approaches indicate a liberal politics of redistribution, multiculturalism, and constitutionalism, and a public policy in which basic values are carefully balanced. The Problem of Value Pluralism: Isaiah Berlin and Beyond is a uniquely comprehensive survey of the political theory of value pluralism and also an original contribution by a leading voice in the pluralist literature. Scholars and researchers interested in the work of Berlin, liberalism, value pluralism, and related ideas will find this a stimulating and valuable source.

A dominant epistemological assumption behind Western philosophy is that it is possible to locate some form of commonality between languages, traditions, or cultures - such as a common language or lexicon, or a common notion of rationality - which makes full linguistic communication between them always attainable. Xinli Wang argues that the thesis of incommensurability challenges this assumption by exploring why and how linguistic communication between two conceptually disparate languages, traditions, or cultures is often problematic and even unattainable. According to Wang's presuppositional interpretation of incommensurability, the real secret of incommensurability lies in the ontological set-ups of two competing presuppositional languages. This book provides many original contributions to the discussion of incommensurability and related issues in philosophy and offers valuable insights to scholars in other fields, such as anthropology, communication, linguistics, scientific education, and cultural studies.

Value pluralism is the idea, associated with the late Isaiah Berlin, that fundamental human values are irreducibly plural and incommensurable. Ends like liberty, equality and community are intrinsic goods which can neither be ranked in an absolute hierarchy nor translated into units of a common denominator. If that is true, how can we choose among such values when they come into conflict in particular cases? In particular, what reason is there to justify the value ranking characteristic of liberal democracy, favouring personal autonomy and toleration? Recent commentators have seen value pluralism as undermining the traditional claims of liberalism to universal authority, rendering it at best no more than one political form among others with no greater claim to legitimacy. Against that view, George Crowder argues that a strong distinctive case for liberalism as a universal project is implied by value pluralism itself. Reflection on the elements of value pluralism yields a set of ethical principles, including respect for universal values, rejection of political utopianism, promotion of value diversity, accommodation of reasonable disagreement, and cultivation of civic virtues. Those principles are best satisfied by a liberal form of politics characterised by a strong commitment to personal autonomy, by policies of moderate redistribution and multiculturalism, and by constitutional restraints on democractic politics. This is the first book-length defence of liberalism on the basis of value pluralism, complementing and extending the work of Berlin and others.

This important book explores the values of equality and diversity as promoted across liberal societies, drawing on various traditions of political and social philosophy, including liberal egalitarianism, existentialism, and elements of post-modernism and post-structuralism. These philosophies are applied to policy and practice debates, especially concerning disability issues, but also relating to gender and multiculturalism. It will be of interest to academics and postgraduate students across a range of social studies disciplines.
