Subjective values should be sharp

Abstract

Elga (Philos Impr 10(5): 1–10, 2010) has argued that, even when no particular subjective probability is required by one’s evidence, perfectly rational people will have sharp subjective probabilities. Otherwise, they would be rationally permitted to knowingly turn down some sure gains. I argue that it is likewise true that, even when we do not possess enough practical reasons for a sharp evaluation (because of optionality or ignorance), perfectly rational people will have sharp subjective values. Those who would be most inclined to reject this argument are those who claim that we are rationally required by either our beliefs that objective values are unsharp (such as strong incomparability, vague value, or parity) or by our own ‘real’ values to have unsharp subjective values. Regarding the former claim, I show that we need not believe that all objective values are sharp to rationally have unsharp subjective values. Regarding the latter claim, I conclude that sharpened subjective values must be ‘real’ (i.e., practically authoritative) because otherwise perfect rationality would be impossible in principle.

Logical expressivism, logical theory and the critique of inferences

Abstract

The basic idea of logical expressivism in the Brandomian tradition is that logic makes inferential relations explicit and thereby accessible to critical discussion. But expressivists have not given a convincing explanation of what the point of logical theories is. Peregrin provides a starting point by observing a distinction between making explicit and explication in Carnap’s sense of replacing something unclear and vague by something clear and exact. Whereas logical locutions make inferential relations explicit within a language, logical theories use formal languages to explicate inferential roles and meanings of ordinary-language expressions. But Peregrin also holds that the whole point of logical theories is to provide perspicuous models of inferential structures in ordinary language practice. This turns explication into a mere continuation of making explicit by other means, and it leads to a one-sided conception of logic which has no room for evaluating inferential practice in light of logical theories. As a more convincing alternative, I suggest that expressivists rely on the method of reflective equilibrium. This approach is closely related to Carnapian explication, but it has the potential of correcting informal inferential practice without dubious ambitions to replace ordinary languages by logical formalisms.

Mapping the continuum of research strategies

Abstract

Contemporary philosophy of science has seen a growing trend towards a focus on scientific practice over the epistemic outputs that such practices produce. This practice-oriented approach has yielded a clearer understanding of how reductive research strategies play a central role in contemporary scientific inquiry. In parallel, a growing body of work has sought to explore the role of non-reductive, or systems-level, research strategies. As a result, the relationship between reductive and non-reductive scientific practices is becoming of increased importance. In this paper, I provide a framework within which research strategies can be compared. I argue that no strategy is reductive or non-reductive simpliciter, rather strategies are more, or are less, reductive than one another according to a frame of reference. That frame of reference is provided by a continuum of possible ways in which the target system might be conceptualised. I illustrate the utility of the framework by deploying it to analyse a recent debate in cancer research. When set within the framework, a prominent reductive strategy—the somatic mutation theory—and a prominent non-reductive strategy—the tissue organisational field theory—do not stand opposed to one another. Rather, they serve as boundary markers to chart the territory of approaches to carcinogenesis within which most strategies in the field fall.

Constructing reality with models

Abstract

Scientific models are used to predict and understand the target phenomena in the reality. The kind of epistemic relationship between the model and the reality is always regarded by most of the philosophers as a representational one. I argue that, complementary to this representational role, some of the scientific models have a constructive role to play in altering and reconstructing the reality in a physical way. I hold that the idealized model assumptions and elements bestow the constructive force of a model on the reality. By recognizing the physical constructive force of some scientific models, the merit of these models could be judged by how successful they are in the reality construction, rather than by the traditional criterion of model-world representation.

From ‘Intersex’ to ‘DSD’: a case of epistemic injustice

Abstract

The 2005 International Consensus Conference on Intersex resulted in a substantive revision of the lexicon and guidelines for treating intersex conditions. The speed with which the new treatment protocol has been adopted by healthcare practitioners and providers is considered unprecedented. However, a number of intersex people and advocacy groups have complained that the recommended revisions are inadequately informed by the testimony of intersex people. In this paper, I argue that such complaints are valid and that, despite the conference conveners stated intention, the revisions perpetuate the epistemic injustice long endured by intersex people. By analyzing the Consensus Conference and its results as a failed attempt to redress the epistemic marginalization of intersex patients and advocacy groups, I am able to identify lingering institutional hurdles to cultivating the virtue of epistemic justice in biomedical practice.

Infertility, epistemic risk, and disease definitions

Abstract

I explore the role that values and interests, especially ideological interests, play in managing and balancing epistemic risks in medicine. I will focus in particular on how diseases are identified and operationalized. Before we can do biomedical research on a condition, it needs to be identified as a medical condition, and it needs to be operationalized in a way that lets us identify sufferers, measure progress, and so forth. I will argue that each time we do this, we engage in epistemic risk balancing that inevitably draws upon values and interests, often including social and ideological values. My main interest here is in the conceptualization of infertility as a disease. Infertility is a rich test case for exploring the interplay between interests and epistemic risk management. There is no uncontested or standardized definition of infertility. The various definitions of it are internally ambiguous and tension-ridden, and in spectacular contradiction with one another. Many interest groups who are invested in framing infertility as a pressing problem deserving of social and medical redress are quick to insist that it is a legitimate ‘disease,’ but they cannot agree on which disease it is, what its symptoms or diagnostic markers are, or even what its basic ontology is. I suggest that there are political explanations for this epistemic mess. Indeed, I contend that there are good scientific and ethical reasons to reduce away the category of ‘infertility,’ especially understood as a scientific or medical category; I argue that we should excise the concept from our research and clinical practices.

Equivalence: an attempt at a history of the idea

Abstract

This paper proposes a reading of the history of equivalence in mathematics. The paper has two main parts. The first part focuses on a relatively short historical period when the notion of equivalence is about to be decontextualized, but yet, has no commonly agreed-upon name. The method for this part is rather straightforward: following the clues left by the others for the ‘first’ modern use of equivalence. The second part focuses on a relatively long historical period when equivalence is experienced in context. The method for this part is to strip the ideas from their set-theoretic formulations and methodically examine the variations in the ways equivalence appears in some prominent historical texts. The paper reveals several critical differences in the conceptions of equivalence at different points in history that are at variance with the standard account of the mathematical notion of equivalence encompassing the concepts of equivalence relation and equivalence class.

Medical knowledge in a social world: Introduction to the special issue

Abstract

Philosophy of medicine has traditionally examined two issues: the scientific ontology for medicine and the epistemic significance of the types of evidence used in medical research. In answering each question, philosophers have typically brought to bear tools from traditional analytic philosophy. In contrast, this volume explores medical knowledge from the perspective offered by social epistemology. While many of the same issues are addressed, the approach to these issues generates both fresh questions and new insights into old debates. In addition, the broader purview offered by social epistemology opens up opportunities to address new topics such as the role of consensus conferences, epistemic injustice, the value of medical knowledge, continuing medical education, and industry funding. This article situates and summarizes the contributions to this special issue.

A puzzle for epistemic WAMs

Abstract

In recent literature, a very popular position about the normativity of assertion claims that standards for epistemically proper assertion vary with practical context, while standards for knowledge do not. This paper shows this claim is strongly incompatible with the received value-theoretic view regarding the relationship between the axiological and the deontic: one of the two has to go.
