This highly original book sheds new light on aspects of incommensurability of values and its implications for ethics and justice. It provides original and innovative analysis of the characteristics of incommensurability in relation to values, and explores the implications of incommensurability for ethics, justice and public decision-making.

There are several different forms of comparability involving prudential values. Comparisons of values in the abstract, of realizations of some value, and of options which realize values, are distinct, and related, though not mutually exclusive. Furthermore, if rough equality is thought of as an evaluative relation in terms of which comparisons can be made, it does not imply incomparability. If it involves epistemic vagueness, this does not imply incomparability, since our not knowing which relation holds does not imply that (...) no relation holds. Finally, if it is true to some degree that some relation holds, there may be some fuzzy ordering. Given that we may not be able coherently to talk about degrees of truth, I propose an open-ended comparability condition, which takes account of rough equality, epistemic vagueness and fuzziness.

Divergent values are often at the heart of natural resource conflict. Using discord over the Grand Staircase-Escalante National Monument in southern Utah, U.S.A. as a case study, I propose that values are perceived as incommensurate because they reflect different realms, with which there exist distinct concepts of what it means to value and distinct, irreducible forms of value expression. I further argue that collaborative, discursive processes are one way to account for plural values in policy and decision making (...) without requiring a common metric, yet they are not without theoretical and practical challenges.

Corporate and commercial values are inducing some healthcare organizations to prescribe a customer service model that reframes the provision of nursing care. In this paper it is argued that such a model is incommensurable with nursing conceived as a moral practice and ultimately places nurses at risk. Based upon understanding from ongoing research on compassion fatigue, it is proposed that compassion fatigue as currently experienced by nurses may not arise predominantly from too great a demand for compassion, but rather from (...) barriers to enacting compassionate care. These barriers are often systemic. The paradigm shift in which healthcare environments are viewed as marketplaces rather than moral communities has the potential to radically affect the evolution of nursing as a discipline. (shrink)

In this chapter I will concentrate on compromise in ethical conflict and disagreement. I will discuss compromises related to disagreement with respect to public decisions between options that represent conflicting incommensurable human values. The central question will be whether in those cases a principled compromise is possible. A ‘principled compromise’ can be defined as a rational way to achieve a trade-off or balance between conflicting values, for instance, by rational assignment of relative weights. I will argue that in some cases (...) incommensurability will prevent a principled compromise in the defined sense. I will show why phrases used by some philosophers, such as ‘making a rational trade-off’, ‘striking the right balance’, ‘finding the Aristotelian Mean’ or ‘splitting the difference’, are based on misunderstandings about the characteristics of incommensurable values that are usually at stake in the pursuit of a compromise. I will show that incommensurable values lack an equivalence relation and how this prevents a determinate trade-off or balance between them. This is especially important with respect to the pursuit of compromises in ethical conflicts, including conflicts of justice, where we need a rational and ethical justification for the final decision. I will argue that the model of deliberative democracy presents a promising procedure for making the final decision legitimate but that, in the relevant cases, it cannot avoid an ethical deficit.

ABSTRACTThis article argues that, although psychoanalysis and history have different conceptions of time and causality, there can be a productive relationship between them. Psychoanalysis can force historians to question their certainty about facts, narrative, and cause; it introduces disturbing notions about unconscious motivation and the effects of fantasy on the making of history. This was not the case with the movement for psychohistory that began in the 1970s. Then the influence of American ego‐psychology on history‐writing promoted the idea of compatibility (...) between the two disciplines in ways that undercut the critical possibilities of their interaction. The work of the French historian Michel de Certeau provides theoretical insight into the uses of incommensurability, while that of Lyndal Roper demonstrates both its limits and its value for enriching historical understanding.

Value pluralists believe in multiple dimensions of value. What does betterness along a dimension have to do with being better overall? Any systematic answer begins with the Strong Pareto principle: one thing is overall better than another if it is better along one dimension and at least as good along all others. We defend Strong Pareto from recent counterexamples and use our discussion to develop a novel view of dimensions of value, one which puts Strong Pareto on (...) firmer footing. We conclude by defending Dimensionalism, the hypothesis that overall value relations are determined solely by how things compare along value dimensions. These are first steps towards a more systematic value pluralism. (shrink)

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. (shrink)

Many recent attacks on consequentialism and several defenses of pluralism have relied on arguments for the incommensurability of value. Such arguments have, generally, turned on empirical appeals to aspects of our everyday experience of value conflict. My intention, largely, is to bypass these arguments and turn instead to a discussion of the conceptual apparatus needed to make the claim that values are incommensurable. After delineating what it would mean for values to be incommensurable, I give an a (...) priori argument that such is impossible. It is widely accepted that value is conceptually tied to desire. I argue that, more specifically, it is proportional to merited desire strength. This connection gives one a metric of all value if there is any such thing. This metric entails that value is a complete ordering over all states of affairs, or, in other words, that value is commensurable. (shrink)

Recent developments in theories for responsible innovation have focused on the importance of actively accounting for values in our technological designs. Leading among these theories is that of Value Sensitive Design which attempts to guide the design process on the basis of evaluative analysis. However, values often come into conflict and VSD has been criticized for not providing a proper method to resolve such inevitable conflicts. This paper examines three such methods and argues that although each has its merits, (...) they all fail to account for a common source of value conflicts known as value incommensurability. Drawing on literature from the field of axiology, this paper argues that by incorporating the evaluative relation of ‘parity’ each of these three methods, and the VSD framework in general, will be able to properly understand the relation which holds between conflicting design options stemming from the incommensurable of values and be able to guide designers in making rational decision in the face of such conflicts.

Two options are incommensurate in value if neither is better than the other, and if a small improvement or worsening of one does not necessarily make it determinately better or worse than the other. If a person faces a sequence of choices between incommensurate options, she may end up with a worse options than she could have had, even though none of her choices are irrational. Yet it seems that rationality should save her from this bad outcome. This is (...) the practical problem posed by incommensurability of values, and it may be solved by a new account of practical reasoning. (shrink)

This introductory article describes the phenomena of incommensurability and incomparability, how they are related, and why they are important. Since incomparability is the more significant phenomenon, the paper takes that as its focus. It gives a detailed account of what incomparability is, investigates the relation between the incomparability of values and the incomparability of alternatives for choice, distinguishes incomparability from the related phenomena of parity, indeterminacy, and noncomparability, and, finally, defends a view about practical justification that vindicates the importance (...) of incomparability — assuming it exists — for practical reason.

The concept of natural otherness can be found throughout the environmental ethics literature. Drawing on this concept, this article pursues two aims. For one, it argues for an account of individual natural otherness as stable difference as opposed to accounts of natural otherness that put more emphasis on independence for the purpose of differentiating individual natural otherness from the concept of wildness. Secondly, this account of natural otherness is engaged to argue for a particular way of theorising the moral standing (...) of individual nonhuman entities. While individual natural otherness in itself does not provide an account of whether an entity matters morally in itself (that is, whether it is morally considerable); it points to an account of incommensurable moral significance for all entities which are attributed moral considerability. That is an often-overlooked alternative to egalitarian or hierarchical accounts or moral significance. Individual natural otherness understood in this way in turn provides another explanatory story for why relational accounts of environmental ethics that strongly emphasise the importance of concepts such as wildness are particularly salient.

I argue that there are two distinct views called ‘value pluralism’ in contemporary axiology, but that these positions have not been properly distinguished. The first kind of pluralism, weak pluralism, is the view philosophers have in mind when they say that there are many things that are valuable. It is also the kind of pluralism that philosophers like Moore, Brentano and Chisholm were interested in. The second kind of pluralism, strong pluralism, is the view philosophers have in mind when (...) they say there are many values, or many kinds of value. It is also the kind of pluralism that philosophers like Stocker, Kekes and Nussbaum have advanced. I separate and elucidate these views, and show how the distinction between them affects the contemporary debate about value pluralism. (shrink)

Kuhn's alleged taxonomic interpretation of incommensurability is grounded on an ill defined notion of untranslatability and is hence radically incomplete. To supplement it, I reconstruct Kuhn's taxonomic interpretation on the basis of a logical-semantic theory of taxonomy, a semantic theory of truth-value, and a truth-value conditional theory of cross-language communication. According to the reconstruction, two scientific languages are incommensurable when core sentences of one language, which have truth values when considered within its own context, lack truth values (...) when considered within the context of the other due to the unmatchable taxonomic structures underlying them. So constructed, Kuhn's mature interpretation of incommensurability does not depend upon the notion of truth-preserving translatability, but rather depends on the notion of truth-value-status-preserving cross-language communication. The reconstruction makes Kuhn's notion of incommensurability a well grounded, tenable and integrated notion.Author Keywords: Incommensurability; Thomas Kuhn; Taxonomic structures; Lexicons; Truth-value; Untranslatability; Cross-language communication.

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 (...) class='Hi'>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.

This paper presents the contribution of the pragmatic sociology of critical capacities to the understanding of environmental conflicts. In the field of 'environmental valuation', nowadays colonised by economics, the approach of plural modes (or 'regimes') of engagement provides a sociological understanding of the unequal power of conflicting 'languages of valuation'. This frame entails a shift from 'values' to 'modes of valuation', and links modes of valuation to modes of practical engagement and coordination with the surrounding environment. Different social sources of (...) incommensurability are thus detected and reframed as critical tension within and among modes of human coordination with the environment. (shrink)

This essay discusses implications of incommensurability of values for justified decision-making, ethics and justice. Under particular conditions incommensurability of values causes what might be called ‘incomplete comparability’ of options. Some leading theorists interpret this in terms of ‘imprecise equality’ and ‘imprecise comparability.’ This interpretation is mistaken and conceals the implications of incommensurability for practical and ethical reasoning. The aim of this essay is to show that, in many cases, incommensurability prevents the assignment of determinate weights to (...) competing values. This may have problematic consequences for a complete and impartial justification of decisions concerning conflicting values to the extent that they depend on the need of weighing them. (shrink)

Needs, Values, Truth brings together of some of the most important and influential writings by a leading contemporary philosopher, drawn from twenty-five years of his work in the broad area of the philosophy of value. The author ranges between problems of ethics, meta-ethics, philosophy of mind, and philosophy of logic and language, looking at questions relating to meaning, truth and objectivity in judgements of value. For this third edition he has added a new essay on incommensurability, in (...) addition to making minor revisions to the existing text. The volume will stand as a definitive summation of his work in this area. (shrink)

ABSTRACTIsaiah Berlin’s idea of value pluralism has been extensively discussed in recent decades. However, there is still much controversy about the actual meaning and implication of the terms “incompatibility” and “incommensurability” when applied to values. This article analyses the Berlinian concept of value pluralism from a theoretical point of view and argues that, following Berlin’s work, incompatibility should be defined as the impossibility of two ends being combined at a maximum level―though it is possible to find compromises (...) between them when not pursued to their maximum―whereas incommensurability refers to the existence of more than one valid, rational solution to a conflict of ends. After commenting on the arguments advanced by other scholars, the presence of a certain idea of rationality in Berlin’s notion of value pluralism is advanced. Finally, it is demonstrated that incompatibility and incommensurability provide Berlin’s pluralism with its characteristic tragic feature which differentiates it from monism. (shrink)

Some theorists believe that there is a plurality of values, and that in many circumstances these values are incommensurable, or at least incomparable. Others believe that all values are reducible to a single super-value, or that even if there is a plurality of irreducible values these values are commensurable. But I will argue that both sides have got it wrong. Values are neither commensurable nor incommensurable, at least not in the way most people think. We are free to believe (...) in incommensurability or not, depending on what particular conception of morality we want to embrace. Incommensurability is accordingly not a theory about value. It is a presupposition that provides a necessary background condition for a certain kind of value to exist. It is therefore not the kind of view that can be morally true or false. As a presupposition, it can only be accepted or rejected on grounds that do not presuppose that morality already exists. Incommensurability is, like the rejection of hard determinism, one of the presuppositions on which morality as we know it happens to be based. (shrink)

In this paper I consider the challenge to rational choice posed by the problem of value incommensurability, and argue that incommensurabilists misrepresentour position as practical reasoners. In essence, I claim that reason has considerably more to work with than their arguments suggest, and that as a result it is possible for us to compare even the deepest values. To say that it is possible for us to compare values is not to say that it is always easy, however, (...) or that thequestion of how best to characterize the common measure that allows for these comparisons isn’t open to vigorous dispute. But I argue that it is one thing to saythat the measure is obscure or that it guides us only imprecisely—and quite another to claim that it is conceptually impossible to weigh the deep values in lightof a common standard.

The spectrum argument purports to show that the better-than relation is not transitive, and consequently that orthodox value theory is built on dubious foundations. The argument works by constructing a sequence of increasingly less painful but more drawn-out experiences, such that each experience in the spectrum is worse than the previous one, yet the final experience is better than the experience with which the spectrum began. Hence the betterness relation admits cycles, threatening either transitivity or asymmetry of the relation. (...) This paper examines recent attempts to block the spectrum argument, using the idea that it is a mistake to affirm that every experience in the spectrum is worse than its predecessor: an alternative hypothesis is that adjacent experiences may be incommensurable in value, or that due to vagueness in the underlying concepts, it is indeterminate which is better. While these attempts formally succeed as responses to the spectrum argument, they have additional, as yet unacknowledged costs that are significant. In order to effectively block the argument in its most typical form, in which the first element is radically inferior to the last, it is necessary to suppose that the incommensurability is particularly acute: what might be called radical incommensurability. We explain these costs, and draw some general lessons about the plausibility of the available options for those who wish to save orthodox axiology from the spectrum argument. (shrink)

According to the accepted translation-failure interpretation, the problem of incommensurability involves the nature of the meaning-referential relation between scientific languages. The incommensurability thesis is that some competing scientific languages are mutually untranslatable due to the radical variance of meaning or/and reference of the terms they employ. I argue that this interpretation faces many difficulties and cannot give us a tenable, coherent, and integrated notion of incommensurability. It has to be rejected. ;On the basis of two case studies, (...) I find that the confrontations between many classical incommensurable languages are not confrontations between two untranslatable languages with different distribution of truth values, but rather the confrontations between incompatible fundamental presuppositions at the ontological level. We can always identify a truth-value gap between two incommensurable languages. Such a truth-value gap indicates a communication breakdown between the two language communities on the one hand, and is caused by the incompatible fundamental presuppositions underlying them on the other. ;I thereby identify the truth-value functional relationship between sentences, instead of the meaning-referential relationship between terms, as the dominant semantic relation between two incommensurable languages. According to my presuppositional interpretation of incommensurability, the real secret of incommensurability lies in the ontological setup of two competing presuppositional languages. When two presuppositional languages with incompatible factual commitments encounter with each other, the confrontation leads to a truth-value gap, and consequently a communication breakdown between them. Formally put, two scientific languages are incommensurable when core sentences of one language, which have truth values when considered within its own context, lack truth values when considered within the context of the other due to an ontological gap between them. ;The presuppositional interpretation makes many significant contributions to the discussion of the issue of incommensurability and the related metaphysical and epistemological issues: It confirms the existence of the phenomenon of incommensurability and makes it metaphysically and epistemologically significant. It establishes the tenability and integrity of the notion of incommensurability. It avoids many alleged unattractive epistemological and metaphysical consequences of the translation-failure interpretation. (shrink)

John Taurek argues that, in a choice between saving the many or the few, the numbers should not count. Some object that this view clashes with the transitivity of ‘better than’; others insist the clash can be avoided. I defend a middle ground: Taurek cannot have transitivity, but that doesn’t doom his view, given a suitable conception of value. I then formalize and explore two conceptions: one context-sensitive, one multidimensional.

The foundation of natural law ethics is a set of basic human goods, such as life and health, knowledge, work and play, appreciation of beauty, friendship, and religion. A disputed question among natural law theorists is whether the basic goods are “incommensurable.” But there is widespread ambiguity in the natural law literature about what incommensurability means, which makes it unclear how this disagreement should be understood and resolved. First, I clear up this ambiguity by distinguishing between incommensurability and (...) incomparability. I show that proponents of New Natural Law Theory hold that basic goods are both incommensurable and incomparable, whereas proponents of Classical Natural Law Theory hold that basic goods are incommensurable but comparable. Second, I critique the leading New Natural Law arguments for the incomparability of basic goods. Throughout the article, I explain why value incommensurability is an essential feature of natural law ethics but value incomparability is not. (shrink)

Can all values be reduced to one or a few fundamental ones? Two values may neither exceed the other in importance nor be equal. In such situation, they cannot be reduced to each other or to a third value, and we can call such values as ”incommensurable”. Drawing on the concept of incommensurable values and what recently is called ”global ethics”, I will argue that if two values from two different cultures conflict, one must pay enough attention to the (...) idea of ”incommensurability of values” in order to avoid a bias judgment of either. I will show how this is the case in the conflict between the Islamic ethics and the secular ethics, examining a specific case: Islamic prohibition on images of Mohammed and the liberalist reverence for freedom of speech.

This chapter considers the difficulties inherent in judgment, and focuses on differences of an ethical variety, shot through with the normative reality of the ethical pluralism of values, from relativisms to monisms, and some of their characteristics conditionality, incompatibility, and incommensurability. It also considers the type of commitments made in relation to these values and different types of conflict. The chapter explains five types of burdens of judgment listed by John Rawls. Rawls' solution for avoiding the general fact of (...) State oppression has collateral effects on moral philosophy and on ethics. Unlike pluralism, relativism questions, in a variety of ways, the possibility of discussion, of justification and of a critique of values. There are at least three distinct types of relativism: radical relativism, conventionalist relativism, and perspectivist relativism. The most notable fact is reasonable pluralism, described as “the diversity of religious, philosophical, and moral doctrines found in modern democratic societies”. (shrink)

This paper casts doubts on John Broome's view that vagueness in value comparisons crowds out incommensurability in value. It shows how vagueness can be imposed on a formal model of value relations that has room for different types of incommensurability. The model implements some basic insights of the ‘fitting attitudes’ analysis of value.

Marx's criticism of Aristotle's theory of value is refuted. Aristotle's theory is explained. Marx is shown is be even more indebted to Aristotle than previously thought, but his argument for a strict commensurability of goods is shown to fail. Aristotle's solution to the problem of the incommensurability of goods, i.e., his proposal of “sufficient” commensurability “with respect to need,” is discussed as a possible solution and is shown to be representable mathematically. Aristotle's theory of value has greater (...) explanatory power than Marx's. (shrink)

Arguments for value incommensurability ultimately depend on a certain diagnosis of human motivation. Incommensurablists hold that each person's basic ends are not only irreducible but also incompatible with one another. It isn't merely that some goals can't, in fact, be jointly realized; values actually compete for influence. This account makes a mistake about the nature of human motivation. Each value underwrites a ceteris paribus evaluation. Such assessments are mutually compatible because the observation that there is something to (...) be said for an outcome from a particular perspective allows for any ultimate evaluation of that outcome; Values can be irreducible without thereby being incommensurable.

Abstract: The paper provides a general account of value relations. It takes its departure in a special type of value relation, parity, which according to Ruth Chang is a form of evaluative comparability that differs from the three standard forms of comparability: betterness, worseness and equal goodness. Recently, Joshua Gert has suggested that the notion of parity can be accounted for if value comparisons are interpreted as normative assessments of preference. While Gert's basic idea is attractive, the (...) way he develops it is flawed: His modeling of values by intervals of permissible preference strengths is inadequate. Instead, I provide an alternative modeling in terms of intersections of rationally permissible preference orderings. This yields a general taxonomy of all binary value relations. The paper concludes with some implications of this approach for rational choice. (shrink)

'Incommensurability' has, in the last forty years, gained wide currency in the literature of philosophy. Kuhn and Feyerabend used the term in the early 1960's to describe an issue in the philosophy of science. They suggested that, when scientific theories are introduced that are significantly different from their predecessors, it may happen that the meanings of key terms differ significantly, and to the extent that scientists may be unable to fully comprehend the new theory until they experience a form (...) of radical conversion, in which they come to fully grasp the new theory. Key contributions have been made to this literature by Bishop, Devitt, Margolis, Sankey, and Scheffler. ;The notion of 'incommensurability' has also been widely used in discussions of ethics. Finnis has used the concept to effect a taxonomy of human values, arguing that there are seven such values and that incommensurability is the feature that contradistinguishes them. Key contributions have been made to this literature by Goodman, Griffin, Pannier, Raz, and Williams. ;In this work I discuss the literature of incommensurability in both the philosophy of science and ethics. I argue that there are at least two quite different notions of incommensurability: one is a well defined notion originally used by mathematicians; the other, less well defined, means, based on the etymology of the word, lacking a common measure. I argue, further, that the discussions of Kuhn and Feyerabend are based on the mathematical notion, while the discussions in ethics are based on the etymological notion. ;Further complicating the discussions in both ethics and the philosophy of science, is the connection between the notions of commensurability and comparability. I argue that the notions describe, differently, equivalent sets. ;Ultimately Kuhn's notion fails because he cannot resolve his arguments for both inexpressibility in a common language and for comparability of competing theories. Finnis's notion fails because incommensurability does not, in fact, uniquely describe the taxonomy for which he argues. (shrink)

Human agents act for reasons that contribute to their good. However, in our explanation of why agents act for reasons that depend on what they value, we encounter the problem of situations in which goods are neither better than others nor are of equal value. The incommensurability of value can then be seen to lead to an incommensurability of reasons for action. Examining rationalist and classical conceptions of human agency, Raz uses the presence of (...) class='Hi'>incommensurability to understand how this affects the relation between reasons and the will, and its effects on our practical reasoning and deliberation. A proper understanding of human agency will take for granted that the goodness of options are incommensurate and that explanations concerning what we want cannot solely be accomplished in terms of reasons.

Several critics have denied value incommensurability – or the claim, roughly, that there is no common measure in terms of which values can be weighed – on the basis of what we might call the argument from easy cases. Although the argument from easy cases is quite popular, what is much less often discussed is what exactly the argument entails – in other words, what sort of further commitments the argument generates. Suppose we grant that easy cases point (...) to the existence of a common measure. How then should we think about this common measure? What is its scope? How widely does it range? I attempt to clarify these questions and in the process evaluate the force of the argument from easy cases. (shrink)

In this Chapter (ch 5 of Strong Evaluation without Moral Sources), as well the following chapters, I defend a hermeneutical but nevertheless non-relativistic moral theory, taking Charles Taylor’s writings on this topic as my guide. Taylor is a realist concerning natural sciences, the ontology of persons and the ontology of goods (or meanings, significances or values). Yet, his realisms in these three areas differ significantly from one another, and therefore one has to be careful not to presuppose too rigid views (...) of what “realism” must be like. Taylor’s moral realism can be called engaged, cultural, phenomenological, hermeneutical or even “expressivist” in a sense to be clarified. According to such value realism, cognitivism is the correct view of our ordinary moral and evaluative reactions and responses to situations. In the realm of evaluative judgements, genuinely correct and incorrect (and better and worse) judgements are possible. These judgements can be implicit in our moral emotions and tacit agent’s knowledge, or more explicit in different articulations. What makes evaluative judgements correct are evaluative properties or “imports” of the situation, and both the evaluative features of situations and our correct responses to them can be further understood in terms of a plurality of (conflicting and incommensurable) goods, ideals or values (section 5.1). In 5.2 I discuss some motivations for non-cognitivism, and try to show that cognitivism can preserve these motivations. I then ask whether value-properties are metaphysically “queer” and what the perspective from which goods are accessible is. I argue for a lifeworldly, engaged access. The evaluative realm is not accessible from a disengaged perspective, but only from within an engaged, lifeworldly perspective. Evaluative properties are not merely a matter of subjective projection nor merely a matter of objective properties independent of valuers. Evaluative properties are relational, and neither the objective nor the subjective pole has priority (5.3). Then I clarify the meaning of “good” and “value”, especially in relation to the central idea that each qualitative distinction of worth expressible in thick, strongly evaluative terms specifies a “value” or a “good” or a “good-making property”. I contrast this with other meanings of “good”. (5.4) After that, I defend the irreducible plurality of such goods against more uniform principles and value monism on the one hand, and I defend their generality against more radical particularisms on the other. Further, I discuss the “lumpy” character of the evaluative realm in relation to incompatibility, incommensurability and conflicts of goods. (5.5). These theses are reconstructed from Charles Taylor’s writings, but authors like John McDowell and Joseph Raz hold similar views. Not unimportantly, Charles Taylor would add a further thesis claiming that there are “constitutive goods” which constitute the goodness of “life goods”, or which in other words bring about the fact that evaluative properties have value. I try to defend the coherence and appeal of engaged, lifeworldly moral realism without taking at first any stand on this further claim about constitutive goods. J. Schneewind (1991, 422) writes in his perceptive review of Sources of the Self that Taylor does not really pay attention to the metaethical debates of 20th century value-theorists. While Taylor’s contribution could have benefited from the work already done in the field, and while Taylor’s philosophizing often leaves it open how his views relate to the views of others, his approach manages to be remarkably original. One might add that due to the theoretically “rhapsodic” nature of Taylor’s work, his theory has received criticism from opposing directions. He tries to defend several theses, which many critics seem to think cannot be held together. Taylor seems to be both communitarian and expressive individualist stressing authenticity; both historicist and universalist; both anthropocentricist and deep ecologist; a realist and a cultural relativist. In this work, some of these seemingly contradictory combinations are defended, while some of them are criticized. (shrink)
