Ruth Mil­likan is one of the most inter­est­ing and influ­en­tial philoso­phers alive. Her work is also hard to pen­e­trate. In this review, I try to present and assess her work on the nature of lan­guage, which is col­lected in this anthol­ogy. I also crit­i­cize her analy­sis of “nat­ural con­ven­tion” as well as her dis­cus­sion of illo­cu­tion­ary acts.

In her ‘Spracherwerb’(2012) Ruth Millikan gives a compelling account of language acquisition based on our ability to track objects. I argue that, and how, it is undermined by her insistence on equating understanding language utterances and sense perception, point to idealist hazards, and plead against propositionality and for imagism in order to safeguard the account’s important potential for giving a comprehensive explication of meaning.

A central idea in Ruth Millikan’s biosemantics is that a representation’s content is restricted to conditions required for the normal success of actions that it has as its function to guide. This paper raises and responds to a problem for this idea. The problem is that the success requirement seems to block us from saying that epistemic modal judgments represent our epistemic circumstances. For the normal success of actions guided by these judgments seems to depend on what is (...) actually the case, not on whether or to what extent various possibilities were supported by our evidence. In response, I argue, first, that actions guided by epistemic modal judgments have as their function to implement strategies for handling epistemic circumstances, second, that the successful performance of this function requires that aspects of these circumstances obtain, and, third, that biosemantics can thus understand epistemic modal judgments as representing these aspects. The recognition of such strategic contents introduces complications; I further argue that these are benign. (shrink)

This paper draws upon the works of Wilfred Sellars, Jerry Fodor, and Ruth Millikan to argue against epistemological holism and conceptual holism. In the first section, I content that contrary to confirmation holism, there are individual beliefs ("basic beliefs") that receive nondoxastic/noninferential warrant. In the earliest stages of cognitive development, modular processes produce basic beliefs about how things are. The disadvantage of this type of basic belief is that the person may possess information that should have defeated the (...) belief but that was not taken into account in the module's operations. For this reason, at more advanced stages of cognitive development, basic beliefs concern how things appear to be. These appearance beliefs are not formed holistically but should be checked against background beliefs before the person infers how things are. In the second section, I argue against functional-role/inferential-role semantics. Championing teleosemantics, I argue that many concepts' meanings are not determined by the meanings of other concepts. Rather, many concepts are skills of knowing how to identify of what the concept is. These skills can be developed independently of other beliefs or skills and are, in an important sense, theory-neutral. (shrink)

These summary notes on Ruth Millikan’s latest book Beyond Concepts: Unicepts, Language, and Natural Information (OUP, 2017) were prepared by Dorit Bar-On for a discussion group that met in Summer 2018. The notes have been lightly edited by Millikan and prepared for online publication with the help of Drew Johnson.

In her landmark book, Language, Thought, and Other Biological Categories (Millikan1984),1 Ruth Garrett Millikan utilizes the idea of a biological function to solve philosophical problems associated with the phenomena of language, thought, and meaning. Language and thought are activities of biological organisms, according to Millikan, and we should treat them as such when trying to answer related philosophical questions. Of special interest is Millikan’s treatment of intentionality. Here Millikan employs the notion of a biological function (...) to explain what it is for one thing in nature, a bee dance (43), for example, to be about another, in this case, the location of a nectar source. My concern in this paper is to understand whether Millikan’s account of intentionality adequately explains how humans achieve reference, in language or thought, to individuals and groups in their environment. In bringing her theory of intentional content to bear on human activities, Millikan focuses largely on natural language. Thus, in what follows, I begin by laying out the biology-based principles that underlie Millikan’s theory of content, then proceed with an explanation of how the theory is to apply to natural language. As it appears, Millikan’s account of how content is determined for natural language terms and sentences rests on the determinacy of intentional content at the psychological level. This leads me to take a careful look at what Millikan says about the content of mental representations, in hopes of finding a sufficient basis there for the application of Millikan’s theory of content to natural language. Ultimately, I conclude that Millikan’s theory faces a problem of vacuity. If we approach the theory as a theory of intentional content, intended to explain the nature of reference, the theory is lacking in an extremely important respect: Millikan explains how it could be one of the biological functions of a mental or natural language term to refer, without telling us precisely what in the natural order constitutes the reference relation..

The notion of function is indispensable to our understanding of distinctions such as that between being broken and being in working order (for artifacts) and between being diseased and being healthy (for organisms). A clear account of the ontology of functions and functioning is thus an important desideratum for any top-level ontology intended for application to domains such as engineering or medicine. The benefit of using top-level ontologies in applied ontology can only be realized when each of the categories identified (...) and defined by a top-level ontology is integrated with the others in a coherent fashion. Basic Formal Ontology (BFO) has from the beginning included function as one of its categories, exploiting a version of the etiological account of function that is framed at a level of generality sufficient to accommodate both biological and artifactual functions. This account has been subjected to a series of criticisms and refinements. We here articulate BFO’s account of function, provide some reasons for favoring it over competing views, and defend it against objections. (shrink)

Millikan and Her Critics offers a unique critical discussion of Ruth Millikan's highly regarded, influential, and systematic contributions to philosophy of mind and language, philosophy of biology, epistemology, and metaphysics. These newly written contributions present discussion from some of the most important philosophers in the field today and include replies from Millikan herself.

Many people argue that history makes a special difference to the subjects of biology and psychology, and that history does not make this special difference to other parts of the world. This paper will show that historical properties make no more or less of a difference to biology or psychology than to chemistry, physics, or other sciences. Although historical properties indeed make a certain kind of difference to biology and psychology, this paper will show that historical properties make the same (...) kind of difference to geology, sociology, astronomy, and other sciences. Similarly, many people argue that nonhistorical properties make a special difference to the nonbiological and the nonpsychological world. This paper will show that nonhistorical properties make the same difference to all things in the world when it comes to their causal behavior and that historical properties make the same difference to all things in the world when it comes to their distributions. Although history is special, it is special in the same way to all parts of the world. (shrink)

Beyond Concepts: Unicepts, Language, and Natural Information. By Millikan Ruth Garrett.

Legal philosophers distinguish between a static and a dynamic interpretation of law. The former assumes that the meaning of the words used in a legal text is set at the moment of its enactment and does not change with time. The latter allows the interpreters to update the meaning and apply a contemporary understanding to the text. The dispute between these competing theories has significant ramifications for social and political life. To take an example, depending on the approach, the term (...) “cruel punishment” used in the US Constitution will be given an 18th century meaning or a contemporary one. -/- The philosophy of language seems to provide greater support to the static approach to legal interpretation. Within this approach the lawmaker is perceived as a speaker and legal texts are interpreted as utterances. As a consequence, interpretation is a quest for the speaker/lawmaker’s intention or the public meaning that prevailed at the time of enactment. Neither the intention nor the public meaning are considered to have changed in time. -/- In this paper I argue that the philosophy of language provides the dynamic approach with an equally robust support as the static one. This support comes from an externalist perspective in semantics, rooted in philosophical pragmatism and supported by Ruth Millikan’s concept of meaning as proper function. Grounding the dynamic approach in a well-founded linguistic philosophy rises to the challenge presented by the originalists’ declaration that “it takes a theory to beat a theory”. (shrink)

How do artifacts get their functions? It is typically thought that an artifact’s function depends on its maker’s intentions. This chapter argues that this common understanding is fatally flawed. Nor can artifact function be understood in terms of current uses or capacities. Instead, it proposes that we understand artifact function on the etiological model that Ruth Millikan and others have proposed for the biological realm. This model offers a robustly normative conception of function, but it does so naturalistically (...) by employing our best scientific theories, in particular natural selection. To help make this case, it proposes “living artifacts” (organisms designed for human purposes through artificial selection) as a bridge between the artifactual and the biological realms. (shrink)

According to “actionism” (Noë 2010), perception constitutively depends on implicit knowledge of the way sensory stimulations vary as a consequence of the perceiver’s self-movement. My aim in this contribution is to develop an alternative conception of the role of action in perception present in the work of Gareth Evans using resources provided by Ruth Millikan’s biosemantic theory of mental representation.

Reductive, naturalistic psychosemantic theories do not have a good track record when it comes to accommodating the representation of kinds. In this paper, I will suggest a particular teleosemantic strategy to solve this problem, grounded in the neurocomputational details of the cerebral cortex. It is a strategy with some parallels to one that Ruth Millikan has suggested, but to which insufficient attention has been paid. This lack of attention is perhaps due to a lack of appreciation for the (...) severity of the problem, so I begin by explaining why the situation is indeed a dire one. One of the main tasks for a naturalistic psychosemantic theory is to describe how the extensions of mental representations are determined. (Such a theory may also attempt to account for other aspects of the “meaning” of mental representations, if there are any.) Some mental representations, e.g. the concept of water, denote kinds (I shall be assuming this is non-negotiable). How is this possible? Unfortunately, I haven’t the space to canvass all the theories out there and show that each one fails to accommodate the representation of kinds, but I will point out the major types of problems that arise for the kinds of theories that, judging by the literature, are considered viable contenders.1 In general, the theories either attempt and fail to account for the representation of kinds, or they fall back on something like an intention to refer to a kind – not exactly the most auspicious move for a reductive theory. There are a number of problems that prevent non-teleosemantic theories from explaining how it is possible to represent kinds. A concept of a kind K must.. (shrink)

An examination of the externalist theories of Tyler Burge, Daniel Dennett and Ruth Millikan.

Attempting art: an essay on intention-dependenceIt is a truism among philosophers that art is intention-dependent—that is to say, art-making is an activity that depends in some way on the maker's intentions. Not much thought has been given to just what this entails, however. For instance, most philosophers of art assume that intention-dependence entails concept-dependence—i.e. possessing a concept of art is necessary for art-making, so that what prospective artists must intend is to make art. And yet, a mounting body of anthropological (...) and art-historical evidence and philosophical argument suggests that not only is such a criterion unsatisfied by most of the art-historical canon, but it also rests on a false premise: concepts of 'art' are not shared between cultures, nor even in the same culture across time. My dissertation aims to rectify this error by first exploring what our commitment to art's intention-dependence actually entails, and then showing that, properly understood, intention-dependence sets a number of important constraints on theories of art with respect to explanatory desiderata such as the success- and failure-conditions of art-attempts, the cross-cultural identification of art, and the reference of 'art' and art-kind terms. I begin by situating art's intention-dependence in the philosophical literature on intentional action, arguing that, properly conceived, intention-dependence is a weak criterion which can be satisfied either directly or indirectly. It therefore does not necessarily entail concept-dependence. I then use this distinction to motivate a new treatment of the success- and failure-conditions for art-attempts, arguing that the extant model's emphasis on compliance with 'the manner intended' is far too restrictive to capture actual artistic practices. I go on to show that Ruth Millikan's model of linguistic conventions supplies an independently plausible explanation of art's concept-independent origins in terms of the development of a system of indirectly intention-dependent conventions called an 'artworld'. I argue that this account of artworld development supplies us with the tools we need to distinguish art-kinds from other artifactual kinds. Finally, I turn my attention to methodological issues, arguing that even though 'art' is a social kind with its roots in arbitrary and historically-contingent networks of conventions, the philosophy of art is not merely an exercise in bare conceptual analysis. In fact, there is now a great deal of evidence to show that the ways we think about 'art' are inconsistent, incomplete, imperialistic, and largely unprincipled. Yet I argue that this does not mean that the artworld data have no bearing on theories of art. Instead, I argue that our best reflective understanding of our artworld practices sets the constraints on the reference of 'art' and art-kind terms. I argue that we have no privileged epistemic access to the ontology of social kinds; our only privilege lies in our ability to determine the proper subject of our inquiries. (shrink)

By significantly diminishing the role intentions play in communication, in Imagination and Convention Lepore and Stone attempt to overthrow the Gricean paradigm which prevails in the philosophy of language. The approach they propose is attractive to theorists of legal interpretations for many reasons. Primary among these is that the more general dispute in the philosophy of language between Griceans and non-Griceans mirrors the dispute between intentionalists and non-intentionalists in legal interpretation. The ideas proposed in Imagination and Convention naturally support the (...) non-intentionalist camp, which makes them unique in the contemporary philosophy of language.In this paper I argue that despite an almost universal acceptance for the Gricean paradigm in legal interpretation, a strong, externalist approach to language, one in which interpretation is based on conventions, not intentions, better reflects the nature of legal language. The latter functions in societies as a written, public discourse to which many individuals contribute; the number of contributions renders the identification of individual intentions impossible, making it badly suited to a Gricean, intention-based analysis. Lepore and Stone’s discourse-based, non-Gricean alternative provides a better tool for the theorist of legal interpretation to analyse legal language. In what follows, I first present an overview of the disputes in legal interpretation that may be affected by Imagination and Convention. In the second section, I analyze several of Lepore and Stone’s theses and apply them to issues in legal interpretation, paying particular attention to their concept of “direct intentionalism.” In the last section, I outline some proposals for finishing the anti-Gricean revolution, which involves Ruth Millikan’s idea of conventions as lineages.

In this paper I consider the idea of external language and examine the role it plays in our understanding of human linguistic practice. Following Michael Devitt, I assume that the subject matter of a linguistic theory is not a psychologically real computational module, but a semiotic system of physical entities equipped with linguistic properties. 2 What are the physical items that count as linguistic tokens and in virtue of what do they possess phonetic, syntactic and semantic properties? According to Devitt, (...) the entities in question are particular bursts of sound or bits of ink that count as standard linguistic entities3 — that is, strings of phonemes, sequences of words and sentences — in virtue of the conventional rules that constitute the structure of the linguistic reality. In my view, however, the bearers of linguistic properties should rather be understood as complex physical states of affairs — that I call, following Ruth G. Millikan, complete linguistic signs4 — within which one can single out their narrow and wide components, that is, (0 sounds or inscriptions produced by the speaker and (if) salient aspects of the context of their production. Moreover, I do not share Devitt's view on the nature of linguistic properties. Even though I maintain the general idea of convention-based semantics — according to which semantic properties of linguistic tokens are essentially conventional — I reject the Lewisian robust account of conventionality. Following Millikan, I assume that language conventions involve neither regular conformity nor mutual understanding. (shrink)

The Philosophy Now series promises to combine rigorous analysis with authoritative expositions. Ruth Abbey’s book lives up to this demand by being a clear, reliable and more than up-to-date introduction to Charles Taylor ’s philosophy. Although it is an introductory book, the amount of footnotes and references ought to please those who want to study the original texts more closely. Abbey’s book is structured thematically: morality, selfhood, politics and epistemology get 50 pages each. The focus is on the internal (...) coherence of Taylor ’s work, not in its critique of or defence against other positions. The chapters are self-containing, but together they give a good total picture of Taylor ’s position. The concluding chapter is a highly interesting preview of Taylor ’s unpublished work-in-progress on secularity, which according to Abbey is comparable in magnitude to Sources of the Self. (shrink)

Feminist bioethicists of a variety of persuasions discuss the 2013 case of Marlise Munoz, a pregnant woman whose medical care was in dispute after she became brain dead.

Both Millikan’s brand of naturalistic analytic philosophy and Husserlian phenomenology have held on to teleological notions, despite their being out of favor in mainstream Western philosophy for most of the twentieth century. Both traditions have recognized the need for teleology in order to adequately account for intentionality, the need to adequately account for intentionality in order to adequately account for meaning, and the need for an adequate theory of meaning in order to precisely and consistently describe the world and (...) life. The stark differences between their accounts of these fundamental concepts stem from radically different conceptions of the world, the natural and life. I argue that Millikan’s teleosemantic approach relies on a teleology of determination by means of the lawfulness of nature that leaves no room for the freedom of self-determination, for reason, or for experience—for the reality of lived human life. In contrast to Millikan’s account, Husserl’s transcendental phenomenology situates teleology as a function of reason and first-personal experience, part of an extended account of intentionality and meaning according to which the full range of our making sense of the world is conceived as a rational activity that is itself a part of that world, and not an unnatural activity to be separated from it. While Husserl’s account of these issues is indeed symptomatic of what Millikan calls “meaning rationalism,” I argue that it is immune to the sorts of problems she claims will plague any such account, since these problems arise only against the background of a set of presuppositions about intentionality that Husserl does not share. Husserl’s position can itself be understood to be within the bounds of a suitably liberal conception of naturalism, and interpreting him in this way it has the added benefit—contra Millikan—of not divorcing teleology from reason, the latter construed as our first-personal striving to make sense of the world as we experience it—of life.

review of Ruth Chang's collection in which I argue that the apparent agreements between the authors disguise underlying important differences.

I propose a reading of The Book of Ruth that takes seriously the pastoral concern for refugees, migrants, and their families that was embodied in the life and teaching of Pope John Paul II.The Book of Ruth models virtues and practices that can help build up a society in solidarity, kindness, and peace. Ruth’s decision to stand beside Naomi demonstrates the value of solidarity in creating a hopeful future for families and communities. Naomi’s role in bringing (...) class='Hi'>Ruth and Boaz together shows prudence and a sense of responsibility for shaping the common good. As for Boaz, he is an exemplary model of generosity and kindness. With respect to peacemaking, The Book of Ruth shows how enmity and distrust between nations might be overcome, with God’s help.

Speakers are confused about identity if they mistake one thing for two or two things for one. I present two plausible models of confusion, the Frege model and the Millikan model. I show how a prominent objection to Fregean models fails and argue that confusion consists in having false implicit beliefs involving the identity relation. Further, I argue that confused identity has characteristic corruptive effects on singular cognition and on the proper function of singular terms in linguistic communication.

In recent years, theorists have debated how we introduce new social objects and kinds into the world. Searle, for instance, proposes that they are introduced by collective acceptance of a constitutive rule; Millikan and Elder that they are the products of reproduction processes; Thomasson that they result from creator intentions and subsequent intentional reproduction; and so on. In this chapter, I argue against the idea that there is a single generic method or set of requirements for doing so. Instead, (...) there is a variety of what I call “anchoring schemas,” or methods by which new social kinds are generated. Not only are social kinds a diverse lot, but the metaphysical explanation for their being the kinds they are is diverse as well. I explain the idea of anchoring and present examples of social kinds that are similar to one another but that are anchored in different ways. I also respond to Millikan’s argument that there is only one kind of “glue” that is “sticky enough” for holding together kinds. I argue that no anchoring schema will work in all environments. It is a contingent matter which schemas are successful for anchoring new social kinds, and an anchoring schema need only be “sticky enough” for practical purposes in a given environment. (shrink)

There has been much discussion of so-called teleosemantic approaches to the naturalization of content. Such discussion, though, has been largely confined to simple, innate mental states with contents such as ?There is a fly here.? Even assuming we can solve the issues that crop up at this stage, an account of the content of human mental states will not get too far without an account of productivity: the ability to entertain indefinitely many thoughts. The best-known teleosemantic theory, Millikan's biosemantics, (...) offers an account of productivity in thought. This paper raises a basic worry about this account: that the use of mapping functions in the theory is unacceptable from a naturalistic point of view. (shrink)

According to the Desire-Based Reasons Model reasons for action are provided by desires. Many, however, are critical about the Model holding an alternative view of practical reason, which is often called valued-based. In this paper I consider one particular attempt to refute the Model, which advocates of the valued-based view often appeal to: the idea of reason-based desires. The argument is built up from two premises. The first claims that desires are states that we have reason to have. The second (...) argues that desires do not add to the stock of reasons the agent has for having them. Together the two theses entail that desires are based on reasons, which they transmit but to which they cannot add. In the paper I deal with a counterexample to the second premise: tie-breaking desires. I first distinguish two interesting cases and argue that only the second challenges the premise. Then I move onto analyze this challenge by focusing on Ruth Chang’s recent employment of it. I show that contrary to its counterintuitive appearance, the challenge can be sustained. However, I also argue that Chang overlooks the full potential of one particular response to the challenge: the introduction of higher-order reasons determining the normative significance of these desires. At the same time, I show that this response has a problem that Chang does not consider. As a result, the response can only partially disarm the challenge of tie-breaking desires; or not at all, depending on what significance we attribute to the counterexamples. (shrink)

The paper begins with an objection to the Desire-Based Reasons Model. The argument from reason-based desires holds that since desires are based on reasons (first premise), which they transmit but to which they cannot add (second premise), they cannot themselves provide reasons for action. In the paper I investigate an attack that has recently been launched against the first premise of this argument by Ruth Chang. Chang invokes a counterexample: affective desires. The aim of the paper is to see (...) if there is a way to accommodate the counterexample to the first premise. I investigate three strategies. I first deal with the idea that the motivation for the premise may be the thesis that an action is intentional if and only if it is done under the guise of perceived reasons. This offers us a way of defending the premise: by showing that actions prompted by affective desires are not intentional. I, however, argue that this strategy is unworkable. This brings me to the second strategy. Here I consider the idea that the premise does not require a conscious normative thought on the part of the agent; in fact, it may not require any such thought, conscious or unconscious. I claim that this strategy too is a failure. Finally, the third approach builds normative judgment in the desire. This is the approach that I think works; in particular, recent work by Jennifer Hawkins may help us accommodate affective desires. The challenge of affective desires, I conclude, can be tackled.

Traditional debate on the metaphysics of gender has been a contrast of essentialist and social-constructionist positions. The standard reaction to this opposition is that neither position alone has the theoretical resources required to satisfy an equitable politics. This has caused a number of theorists to suggest ways in which gender is unified on the basis of social rather than biological characteristics but is “real” or “objective” nonetheless – a position I term social objectivism. This essay begins by making explicit the (...) motivations for, and central assumptions of, social objectivism. I then propose that gender is better understood as a real kind with a historical essence, analogous to the biologist’s claim that species are historical entities. I argue that this proposal achieves a better solution to the problems that motivate social objectivism. Moreover, the account is consistent with a post-positivist understanding of the classificatory practices employed within the natural and social sciences. (shrink)

Ethological theories usually attribute semantic content to animal signals. To account for this fact, many biologists and philosophers appeal to some version of teleosemantics. However, this picture has recently came under attack: while mainstream teleosemantics assumes that representational systems must cooperate, some biologists and philosophers argue that in certain cases signaling can evolve within systems lacking common interest. In this paper I defend the standard view from this objection.

One of the main tenets of current teleosemantic theories is that simple representations are Pushmi-Pullyu states, i.e. they carry descriptive and imperative content at the same time. In the paper I present an argument that shows that if we add this claim to the core tenets of teleosemantics, then (1) it entails that, necessarily, all representations are Pushmi-Pullyu states and (2) it undermines one of the main motivations for the Pushmi-Pullyu account.

It is my goal in this paper to offer a strategy for translating universal statements about utopia into particular statements. This is accomplished by drawing out their implicit, temporally embedded, points of reference. Universal statements of the kind I find troublesome are those of the form ‘Utopia is x’, where ‘x’ can be anything from ‘the receding horizon’ to ‘the nation of the virtuous’. To such statements, I want to put the questions: ‘Which utopias?’; ‘In what sense?’; and ‘When was (...) that, is that, or will that be, the case for utopias?’ Through an exploration of these lines of questioning, I arrive at three archetypes of utopian theorizing which serve to provide the answers: namely, utopian historicism, utopian presentism, and utopian futurism. The employment of these archetypes temporally grounds statements about utopia in the past, present, or future, and thus forces discussion of discrete particulars instead of abstract universals with no meaningful referents.

SYMMETRY IN PHYSICS: FROM PROPORTION AND HARMONY TO THE TERM OF METALENGUAJE -/- Ruth Castillo Universidad Central de Venezuela -/- The revolutionary changes in physics require a careful exploration of the way in which concepts depend on the theoretical structure in which they are immerse. A historical reconstruction allows us to show how the notion of symmetry evolves from the definition as proportion and harmony to its consideration within the language of contemporary physics, as a linguistic meta-theoretical requirement in (...) physical theories. In contemporary terms, symmetry is a fundamental category of research to which the usual categories of the natural sciences can be reduce in: space, time, causality, interaction, matter, strength, etc ... Thus, symmetry is a concept with different meanings: heuristically symmetric models inspire scientists in the search for solutions to different problems. Methodologically, symmetric structures are use to make theories, laws with invariant properties. A description of nature in terms of symmetric structures and symmetry ruptures seems to be the proper way to describe the complexity of reality. (shrink)

Eugenics is an overused, and often mis-used phrase, when applied to the handicap ground for abortion, argues Ruth McNally. Instead, we should be aware of the power of eubionics – the quest for individual, bodily perfection.

In virtue of what is something a reason for action? That is, what makes a consideration a reason to act? This is a metaphysical or meta-normative question about the grounding of reasons for action. The answer to the grounding question has been traditionally given in ‘pure’, univocal terms.

The paper 1) surveys the three leading ‘pure’ answers to the (...) question of a normative ground, 2) examines one or two of the most difficult problems for each, proposing along the way a new objection to one, and 3) argues that a particular hybrid view about normative grounds –‘hybrid voluntarism’ – avoids each of the main problems faced by the three leading ‘pure’ views.

This paper argues for the existence of a fourth positive generic value relation that can hold between two items beyond ‘better than’, ‘worse than’, and ‘equally good’: namely ‘on a par’.

This paper investigates two puzzles in practical reason and proposes a solution to them. First, sometimes, when we are practically certain that neither of two alternatives is better than or as good as the other with respect to what matters in the choice between them, it nevertheless seems perfectly rational to continue to deliberate, and sometimes the result of that deliberation is a conclusion that one alternative is better, where there is no error in one’s previous judgment. Second, there are (...) striking differences between rational agents – some rational agents have most reason to pursue careers on Wall Street while others have most reason to take up a career in teaching, or scuba diving, or working for political causes. These differences aren’t plausibly explained by ‘passive’ facts about our psychology or their causal interaction with our environment; instead, these facts seem in some sense to ‘express who we are’. But what is this sense? These puzzles disappear if we adopt a novel view about the source of the normativity of reasons – some reasons are given to us and others are reasons in virtue of an act of will. We make certain considerations reasons through an act of will and thus sometimes make it true through an act of agency that we have most reason to do one thing rather than another. (shrink)

This paper is the introduction to the volume. It gives an argumentative view of the philosophical landscape concerning incommensurability and incomparability. It argues that incomparability, not incommensurability, is the important phenomenon on which philosophers should be focusing and that the arguments for the existence of incomparability are so far not compelling.
