This essay is part of a larger project aimed at making sense of rational thought and agency as part of the natural world. It provides a semantic framework for thinking about the contents of: 1) descriptive thoughts and sentences having a representational or mind-to-world direction of fit, and which manifest our capacity for theoretical rationality; and 2) prescriptive and intentional sentences having an expressive or world-to-mind direction of fit, and which manifest our capacity for practical rationality. I use (...) a modified version of Allan Gibbard’s hyperstate semantics, employing both maximally determinate possible worlds and maximally determinate plans of action, as a basis for providing a unified understanding of moral judgments and expressions of individual and collective intentionality – they one and all give voice to our ability as rational agents to adopt the perspectives of various individuals within a community and consider how we would behave were we in their positions. In the course of spelling out the view I draw on and criticize ideas that Wilfrid Sellars advanced in the middle of the 20th century, while employing the tools of contemporary modal logic and model-theoretic semantics to give perspicuous formulation to his thought that the moral judgment ‘one ought to do A’ should be understood in terms of the collective intention ‘we shall do A’, where the pronoun denotes the unrestricted class of rational agents and the ‘ought’ is in some sense unconditionally binding.

Toulmin is one of the three or four best-known philosophers of science who, beginning in the late 1950’s, attempted a thoroughgoing criticism of logical positivism (the philosophy of science which predominated at that time). The paper argues that Toulmin depends upon the same sort oftheory-observation dichotomy which resulted in many of the difficulties which bedeviled logical positivism. Thus Toulmin’s criticism is neither as radical nor as trouble-free as many suppose.

There seems a potential tension between Hume's naturalistic project and his normative ambitions. Hume adopts what I call a methodological naturalism: that is, the methodology of providing explanations for various phenomena based on natural properties and causes. This methodology takes the form of introducing ‘the experimental method of reasoning into moral subjects’, as stated in the subtitle of the Treatise; this ‘experimental method’ seems a paradigmatically descriptive one, and it remains unclear how Hume derives genuinely normative prescriptions from this (...) methodology. In resolving this problem, I will argue that Hume's naturalistic methodology – that is, his ‘experimental philosophy’, or what has come to be known as his experimental method – consists of the systematization of phenomena pertaining to human nature. In applying his experimental method to normative subjects, Hume systematizes our normative judgements, deriving general principles of normative justification; he then reflexivel... (shrink)

Izard (2010) did not seek a descriptive definition of emotion—one that describes the concept as it is used by ordinary folk. Instead, he surveyed scientists’ prescriptive definitions—ones that prescribe how the concept should be used in theories of emotion. That survey showed a lack of agreement today and thus raised doubts about emotion as a useful scientific concept.

In applying his experimental method to normative subjects, Hume systematises our normative judgments, deriving general principles of normative justification; he then reflexively applies these principles to the pre-philosophical judgments from which they derive, dismissing and/or correcting those that do not accord with his systematised account. I will argue that Hume’s experimental method, far from being wholly descriptive, is in fact thoroughly infused with normativity; furthermore, the very application of this methodology to our normative judgments reveals Hume’s normative ambitions.

This paper distinguishes between five different approaches to social discount rates in climate change economics, criticizes two of these, and explains how the other three are to some degree mutually compatible. It aims to shed some new light on a longstanding debate in climate change economics between so-called “descriptivists” and “prescriptivists” about social discounting. The ultimate goal is to offer a sketch of the conceptual landscape that makes visible some important facets of the debate that very often go unacknowledged.

People’s beliefs about normality play an important role in many aspects of cognition and life (e.g., causal cognition, linguistic semantics, cooperative behavior). But how do people determine what sorts of things are normal in the first place? Past research has studied both people’s representations of statistical norms (e.g., the average) and their representations of prescriptive norms (e.g., the ideal). Four studies suggest that people’s notion of normality incorporates both of these types of norms. In particular, people’s representations of what (...) is normal were found to be influenced both by what they believed to be descriptively average and by what they believed to be prescriptively ideal. This is shown across three domains: people’s use of the word ‘‘normal” (Study 1), their use of gradable adjectives (Study 2), and their judgments of concept prototypicality (Study 3). A final study investigated the learning of normality for a novel category, showing that people actively combine statistical and prescriptive information they have learned into an undifferentiated notion of what is normal (Study 4). Taken together, these findings may help to explain how moral norms impact the acquisition of normality and, conversely, how normality impacts the acquisition of moral norms. (shrink)

This paper examines critically the current state of affairs in philosophy of science. It focuses on the well-Known puzzle about the relationship between the normative prescriptive methodology of science and positive descriptive history of science. This puzzle has dogged philosophers of science for over a generation and is still controversial. My conclusion is that there is really no escape from it. The best way to characterize it is as follows: "philosophy of science without history of science is empty; (...) history of science without philosophy of science is blind.". (shrink)

IN this note I propose to make some general remarks concerning the analytical forays carried out into moral discourse by some leading figures in the modern ‘linguistic’ tradition. The philosophers I am going to speak of, may all be said to be attempting some sort of ‘descriptive’ analysis, but my thesis is that philosophers such as Toulmin and Baier are attempting something that is significantly different from what a philosopher such as Nowell-Smith is attempting. I will suggest, in the (...) following section, that the expression—‘the logic of moral discourse’—seems to be understood by these two groups of linguistic philosophers in two different ways and that one of these ways involves a more ambitious claim, than does the other, on behalf of the philosopher embarking upon a conceptual analysis of moral discourse. The manner in which, it seems to me, Toulmin and Baier understand this expression is the one that involves the more ambitious claim. In the final section of this paper I suggest that the more ambitious claim involves overloading the so-called Linguistic method to force it do a job that it seems at least not suited to perform.

Barons's target article approaches errors in decision-making by defining three kinds of models: normative, descriptive, and prescriptive. Baron's prescriptive model is at the center of this commentary. From a theoretical perspective, is Baron's prescriptive model a set of rules through which one can move from the descriptive to the normative? Or is it a practical goal one can achieve as opposed to a normative unachievable theoretical ideal? Delineating an efficient prescriptive account for decision making (...) necessarily depends on a very specific normative model. However, Baron's normative consequentialism model is too general to enable adequate prescriptive accounts. (shrink)

Virtually all philosophers of science have construed fundamental theories as descriptions of entities, properties, and/or structures. Call this the “descriptive-ontological” view. I argue that this view is incorrect, at least insofar as physical theories are concerned. I propose a novel construal of theories that I call the “prescriptive-dynamical” view. The central tenet of this view, roughly put, is that the _essential_ content of fundamental physical theories is a _prescription for interfacing with natural systems and translating local data into (...) compact theoretical language_. The descriptive-ontological aspects of theories, if any, are taken as _inessential_ content on this view: they do not contribute to the predictive success of the theory. Rather than describing _what is there_, the essence of a physical theory is to tell us _what to do_ when interfacing with a physical system. (shrink)

This thesis modifies the wording of William Clifford’s 1877 evidence principle (that ‘it is wrong always, everywhere, and for anyone, to believe anything upon insufficient evidence’) to propose an explicitly moral principle, restricted to descriptive beliefs (about what is or is not the case) and excluding prescriptive beliefs (about what ought or ought not to be the case). It considers potential counter-examples, particularly William James’s 1896 defence of religious belief; and concludes that the modified principle survives unscathed. It (...) then searches for suitable criteria for ‘sufficient’ and ‘insufficient’ evidence, first within a Bayesian framework enriched by pragmatic considerations, and finally by returning to Clifford’s conception of our shared responsibilities to our shared epistemic asset. Combined with elements of Edward Craig’s (1990, 1999) ‘state-of-nature’ theory of knowledge this gets us to a minimum threshold to avoid insufficient evidence and an aspirational criterion of sufficient evidence.

Ethical guidelines for psychologists are meant to stimulate and help psychologists to act appropriately with respect to clients, colleagues, and other individuals involved in their professional relations. This paper focuses on the similarity of codes of ethics of psychologists in European countries in general, and on specific ethical dilemmas in the area of work and organizations in particular. First, an overview is given of the development of ethical guidelines in Europe and the USA. Second, the results are presented of a (...) survey by E-mail amongst members of the European Federation of Psychologists’ Associations (EFPA) to identify the differences and similarities between ethical guidelines of the affiliate members. Third, the potential dilemmas of stakeholders in work and organizational assessment are addressed. Finally, the results of a survey among Dutch selection psychologists are presented. The purpose of this study was to examine a possible tension between normative behavior and attitudes about normal behavior. It was concluded that ethical guidelines of European countries cover comparable (sub-)principles and that there are indications that individual psychologists agree with the written principles. In addition, suggestions for future research are given. (shrink)

Koriat & Goldsmith's abstract correspondence metaphor is unlikely to prove useful to memory science. It aims to motivate and inform the investigation of everyday memory, but that movement has prospered without it. The irrelevance of its competitor – the more concrete storehouse metaphor – as a guiding force in memory research presages a similar fate for the correspondence perspective.

Simple heuristics and regression models make different assumptions about behaviour. Both the environment and judgment can be described as fast and frugal. We do not know whether humans are successful when being fast and frugal. We must assess both global accuracy and the costs of Type I and II errors. These may be “smart heuristics that make researchers look simple.”.

In an engaging and provocative paper, Linda Trevino and Gary Weaver spell out the differences between the methodological approach characteristic of the natural sciences on the one hand and that of normative inquiry on the other (Trevino and Weaver, 1991). Near the end of their paper they raise a haunting question that will have increasing significance as the management literature in ethics evolves: namely, “Can the two approaches be integrated?”As C. P. Snow (1962) noted, no one can deny either the (...) stark differences between the two worlds of normative and empirical inquiry, or the mutual suspicion shown by their inhabitants. The methodology of natural science implies a non-normative, thoroughly descriptive vision of the world in which reality awaits discovery by the scientist prepared to use increasingly sophisticated techniques. In contrast, the methodology of normative inquiry, i.e., that of traditional moral philosophy, implies a world-vision in which most important issues are allocated to ethics, where empirical pursuits are frequently trivial and always require ethical guidance, and where empirical theories contain normative presuppositions unrecognized as normative even by their scientific adherents.

For Knobe, observers evaluate mental states by comparing agents' statements with the attitudes they are expected to hold. In our analysis, Knobe's model relies primarily on what agents should think, and little on expectancies of what they would think. We show the importance and complexity of including descriptive and prescriptive norms if one is to take expectancies seriously.

This article discusses the relationship between the origins of the concept of post-normal science, its potential as a heuristic and the phenomenon of complex science entailed policy problems in late industrial societies. Drawing on arguments presented in the early works of Funtowicz and Ravetz, it is proposed that there is a fundamentally empirical character to the post-normal science call for democratizing expertise, which serves as an antidote to late industrial poisoning of the fairy tale ideal of a clean divide between (...) science and politics. Post-normal science extended-peer-review methodology is interpreted as a response to a crisis in the governance of science. Rather than viewing extended-peer-review processes as products of the post-normal science discourse, here the post-normal science discourse is understood to provide a heuristic lens through which existing complex science/society collaborations and conflicts can be better understood. Two different post-normal science situations—management of mega-contamination in Bitterfeld, Germany, and eviction of the Parakuiyo Maasai from the eastern wetlands of the Usangu plains of Tanzania—are presented and the implications of their de facto extended-peer-review structures are discussed, to illustrate this heuristic potential.

To cut a convincing figure again in jurisprudence — which is my present field of concern— natural law theory, by which I mean and shall mean throughout, traditional natural law theory, basically the theory of St.Thomas, must be made convincing again in ethics.

Research on ethical norms has grown in recent years, but imprecise language has made it unclear when these norms prescribe “what ought to be” and when they merely describe behaviors or perceptions (“what is”). Studies of ethical norms, moreover, tend not to investigate whether participants were influenced by the prescriptive aspect of the norm; the studies primarily demonstrate, rather, that people will mimic the behaviors or perceptions of others, which provides evidence for the already well-substantiated social proof theory. In (...) this review article, we delineate three streams of norms research in business ethics: behavioral, perceptual, and prescriptive. We argue that by properly categorizing norms, and designing studies to investigate when prescriptions, more than mere mimicry, improve ethical outcomes in organizations, researchers can enhance managers’ efforts to promote ethical outcomes in organizations.

The aim of this paper is to show that descriptive statements can be action-Guiding; that oughts and imperatives, If they are to be justified at all, Must be derived from statements of fact; that factual-Prudential moral reasoning is logically universalizable; and that the demand for universalizability, And thus ultimately for moral reasoning, Is itself only prudentially justifiable. These points are argued by way of an examination and criticism of hare's discussion of prescription and universalizability in moral reasoning.

Statements about a person's good slip into and out of our ordinary discourse about the world with nary a ripple. Such statements are objects of belief and assertion, they obey the rules of logic, and they are often defended by evidence and argument. They even participate in common-sense explanations, as when we say of some person that he has been less subject to wild swings of enthusiasm and disappointment now that, with experience, he has gained a clearer idea of what (...) is good for him. Statements about a person's good present themselves as being about something with respect to which our beliefs can be true or false, warranted or unwarranted. Let us speak of these features as the descriptive side of discourse about a person's good. (shrink)

Empirical ethics research is increasingly valued in bioethics and healthcare more generally, but there remain as yet under-researched areas such as pharmacy, despite the increasingly visible attempts by the profession to embrace additional roles beyond the supply of medicines. A descriptive and critical review of the extant empirical pharmacy ethics literature is provided here. A chronological change from quantitative to qualitative approaches is highlighted in this review, as well as differing theoretical approaches such as cognitive moral development and the (...) four principles of biomedical ethics. Research with pharmacy student cohorts is common, as is representation from American pharmacists. Many examples of ethical problems are identified, as well as commercial and legal influences on ethical understanding and decision making. In this paper, it is argued that as pharmacy seeks to develop additional roles with concomitant ethical responsibilities, a new prescription is needed for empirical ethics research in pharmacy—one that embraces an agenda of systematic research using a plurality of methodological and theoretical approaches to better explore this under-researched discipline.

While the theory of relative plausibility is presented by Allen and Pardo as a descriptive theory of the proof process, this commentary discusses their theory as a possible starting point for a prescriptive theory of evidence assessment. Generally, naturalness and simplicity are necessary for the success of such a theory. The theory of relative plausibility is very promising in this respect, as its key concept is the straightforward and intuitive notion of explanation, according to which an explanation is (...) an answer to a “why” question. Still, both the explanatory and the comparative dimensions of relative plausibility are in need of elaboration if one wants to give advice on evidence assessment in terms of Allen and Pardo’s framework. For one thing, it is necessary to examine the epistemological status of the various explanatory criteria regarding their potential as guides to truth or likelihood. Only epistemic criteria should be included in recommendations to fact-finders. Moreover, given the author’s interpretation of the ‘beyond any reasonable doubt’ standard, it is unclear what the comparative dimension amounts to in criminal trials. At least a comparison of the kind involved in the author's account of civil trials standards is absent in their interpretation of BARD. If the comparative dimension of relative plausibility is relevant at all in criminal trials, it must be clarified what is to be compared. (shrink)

ABSTRACT In “Race, Multiculturalism, and Democracy,” Robert Gooding-Williams offers an insight. He writes: “Our sense of ourselves and of the possibilities existing for us is, to a significant degree, a function of the descriptions we have available to us to conceptualize our intended actions and prospective lives…. ‘Hence if new modes of description come into being, new possibilities of action come into being in consequence.’” In this article, I discuss the philosopher's role in the articulation of new descriptions and thus (...) new possibilities. I argue that potential modes of bold and assertive comportment are conjured when new insurrectionist descriptions are articulated within oppressed populations. To bring this to a higher resolution, I discuss the pervasiveness of dialectical conflict, the need to creatively reorient the descriptions of oppressed groups toward liberation, and the need for more than one prescriptive mode of social amelioration.

Exactly how do the sign/symbol/token systems of endo- and exo-biosemiosis differ from those of cognitive semiosis? Do the biological messages that integrate metabolism have conceptual meaning? Semantic information has two subsets: Descriptive and Prescriptive. Prescriptive information instructs or directly produces nontrivial function. In cognitive semiosis, prescriptive information requires anticipation and “choice with intent” at bona fide decision nodes. Prescriptive information either tells us what choices to make, or it is a recordation of wise choices already (...) made. Symbol systems allow recordation of deliberate choices and the transmission of linear digital prescriptive information. Formal symbol selection can be instantiated into physicality using physical symbol vehicles (tokens). Material symbol systems (MSS) formally assign representational meaning to physical objects. Even verbal semiosis instantiates meaning into physical sound waves using an MSS. Formal function can also be incorporated into physicality through the use of dynamically-inert (dynamically-incoherent or -decoupled) configurable switch-settings in conceptual circuits. This paper examines the degree to which biosemiosis conforms to the essential formal criteria of prescriptive semiosis and cybernetic management. (shrink)

I use a distinction between single-minded and indifferent choice attitudes, modeled across maximally determinate plans of action, as a basis for interpreting deontic claims – about what ought, ought not, and may be done – as expressing a mode of relation between mind and world that gives voice to the exercise of practical rationality. At the same time, I use maximally determinate possible worlds to model descriptive claims in order to understand them as involving a mode of relation between (...) mind and world that manifests our theoretical rationality. The result is of interest to both linguists looking for a formal treatment of deontic modality that captures the role prescriptive mental states play in our lives, and philosophers interested in substantive questions about action-guiding and representational mental states as exercises of practical and theoretical rationality.

This response agrees with Stanovich's emphasis on the need for decentering, and, in response to Beyth-Marom, attempts to clarify the normative-prescriptive-descriptive distinction and point in the direction of prescriptive models. It takes issue with Cabanac and with Lindsay & Gorayska.

When do descriptive regularities become prescriptive norms? We examined children's and adults' use of group regularities to make prescriptive judgments, employing novel groups that engaged in morally neutral behaviors. Participants were introduced to conforming or non-conforming individuals. Children negatively evaluated non-conformity, with negative evaluations declining with age. These effects were replicable across competitive and cooperative intergroup contexts and stemmed from reasoning about group regularities rather than reasoning about individual regularities. These data provide new insights into children's group (...) concepts and have important implications for understanding the development of stereotyping and norm enforcement. (shrink)

Increasing attention is being paid to spirituality in nursing practice. Much of the literature on spiritual care uses the nursing process to describe this aspect of care. However, the use of the nursing process in the area of spirituality may be problematic, depending upon the understandings of the nature and intent of this process. Is it primarily a descriptive process meant to make visible the nursing actions to provide spiritual support, or is it a prescriptive process meant to (...) guide nursing actions for intervening in the spirituality of patients? A prescriptive nursing process approach implies influencing, and in some cases reframing, the spirituality of patients and thereby extends beyond general notions of spiritual support. In this paper we discuss four problematic assumptions that form the basis for a prescriptive approach to spiritual care. We conclude that this approach extends the nursing role beyond appropriate professional boundaries, making it ethically problematic. (shrink)

The contemporary sociology of morality is a form of descriptive ethics that shrinks away from any sort of prescriptive ethics. Building on the moral philosophies of John Dewey, and also of Alasdair MacIntyre and Paul Ricoeur, and in dialogue with recent work by Stefan Bargheer, this article proposes a more ambitious program of critical social ethics that connects concerns with character and the common good but tempers them with attention to alienation and oppression.
