Justin Garson has recently argued that proper functions are proximal activities of traits selected by phylogenetic or ontogenetic selection processes, and that traits are dysfunctional only if they cannot perform their proper functions for constitutional reasons. We partially agree with Garson, but reject the view that functions are proximal activities, as well as his account of dysfunctions. Instead, we propose our own theory that biological functions are selected dispositions and that a trait is dysfunctional in virtue of not having the (...) dispositions for which it was selected. This account can explain both defects (or dysfunctions in Garson’s sense) and dysfunctions due to environmental factors. Moreover, it offers a neat way to explain the graduality of dysfunction.

According to Karen Neander’s causal-informational teleosemantics, the contents of perceptual states depend on the etiological response functions of sensory-perceptual systems. In this paper, I argue that this theory is, despite its virtues, unable to explain how humans and other animals are capable of perceiving properties with which no sensory-perceptual system has ever been confronted. After rejecting Neander’s own proposal in terms of second-order similarity and a proposal inspired by Ruth Millikan in terms of simplicity, I offer a solution which equates (...) functions with manifestations of dispositions that made a difference to evolutionary success. My suggestion is able to generate determinate and plausible contents for new perceptual states while still preserving the idea that etiological functions explain evolutionary success. (shrink)

Teleosemantic theories aim to naturalize mental representation through the use of functions, typically based on past selection processes. However, the historical dependence of these theories has faced severe criticism, leading some philosophers to develop ahistorical alternatives. -/- This paper presents a new dilemma for all ahistorical teleosemantic theories, focusing in particular on the theories proposed by Timothy Schroeder and Bence Nanay. These theories require certain dispositions in the producers or consumers of mental representations. But the appeal to dispositions puts the (...) proponents in an undesirable position: mental content is either overly dependent on current circumstances or ultimately dependent on historical factors.

This paper introduces the line-drawing challenge for ability-based accounts of health. What degree of which abilities is required for complete health? I argue that the answers provided by existing theories are flawed and propose the Blueprint View. On this view, an organism is completely healthy if and only if it has the abilities it would have in its design state, where design is determined by the etiology of its traits. This view provides an objective, naturalistic distinction between health and non-health. (...) It strikes a balance between pure physiology and well-being, and distinguishes treatment from enhancement, as well as real pathology from pathologized variation. (shrink)

In dynamic system control, cognitive mechanisms and abilities underlying performance may vary depending on the nature of the task. We therefore investigated the effects of system structure and its interaction with cognitive abilities on system control performance. A sample of 127 university students completed a series of different system control tasks that were manipulated in terms of system size and recurrent feedback, either with or without a cognitive load manipulation. Cognitive abilities assessed included reasoning ability, working memory capacity, and cognitive (...) reflection. System size and recurrent feedback affected overall performance as expected. Overall, the results support that cognitive ability is a good predictor of performance in dynamic system control tasks but predictiveness is reduced when the system structure contains recurrent feedback. We discuss this finding from a cognitive processing perspective as well as its implications for individual differences research in dynamic systems. (shrink)

In this article, we show that historical naturalistic theories of biological function can meet central desiderata, while ahistorical alternatives cannot. To this end, we develop a comprehensive taxonomy of naturalistic theories of function and malfunctioning and argue that all possible ahistorical theories are unable to meet the distinction challenge (i.e. explaining why different traits have different functions) and the futile functioning challenge (i.e. allowing functions and malfunctions even when the fulfilment of the function serves no further purpose). In contrast, the (...) selected effects theory and other historical theories can easily meet these two challenges. We, therefore, have good reason to leave ahistorical theories behind. (shrink)

Perceptual representations are either correct or incorrect. Their correctness depends on their content and on the way the world is. Teleosemantics delivers compelling explanations of why our perceptual representations have contents, whereby it assigns the notion of "function" a central explanatory role. The author of this thesis engages in the search for a theory of function suited for this purpose. After a detailed evaluation of the selected effects​ theory and dispositional theories, the author argues that a synthesis is best suited (...) to be used by teleosemantics. (shrink)

Potentialities are properties that can manifest. Many potentialities are instantiated in virtue of having causal bases that are possible causes for their manifestations. This chapter shows that a closer look at potentialities and their causal bases studied in the life sciences (from cell biology to psychiatry) gives us good reasons to revise our philosophical assumptions about causal bases. The investigation reveals that causal bases are often more dynamic and dependent on interactions with the environment than previously assumed. In particular, we (...) argue that causal bases in the life sciences are regularly extrinsic and processual and that potentialities in the life sciences have causal bases at different levels.

Der These des erweiterten Geistes zufolge befinden sich manche mentalen Repräsentationen außerhalb der körperlichen Grenzen der Wesen, zu denen sie gehören. Einer der stärksten Einwände gegen diese These stellt das Argument der Nichtabgeleitetheit von Frederick Adams, Ken Aizawa und Jerry Fodor dar. Dieses Argument setzt voraus, dass genuine mentale Repräsentationen nichtabgeleitete Gehalte haben – ihre semantischen Eigenschaften sind also nicht durch Absichten, Wünsche oder Konventionen konstituiert. Repräsentationen mit nichtabgeleitetem Gehalt finden sich jedoch, so das Argument weiter, nur innerhalb der körperlichen (...) Grenzen mentaler Wesen. Ich werde dafür argumentieren, dass das Argument der Nichtabgeleitetheit scheitert, da es insbesondere bei Tieren externe Repräsentationen gibt, deren Gehalt nichtabgeleitet ist. Dies folgt jedenfalls aus der aussichtsreichsten Theorie nichtabgeleiteter Repräsentationen, der Teleosemantik, und es gibt gute Gründe anzunehmen, dass auch andere naturalistische Gehaltstheorien dieselbe Implikation haben.

Virtue Reliabilism holds that knowledge is a cognitive achievement—an epistemic success that is creditable to the cognitive abilities of the knowing subject. Beyond this consensus, there is much disagreement amongst proponents of virtue reliabilism about the conditions under which the credit-relation between an epistemic success and a person’s cognitive abilities holds. This paper aims to establish a new and attractive view of this crucial relation in terms of difference-making. We will argue that the resulting theory, Difference-Making Virtue Epistemology, can deal (...) with cases of epistemic luck and testimonial knowledge while revealing the common core of knowledge and other achievements.

The contents of representations in non-human animals, human core cognition, and perception cannot precisely be characterized by sentences of a natural language. However, this fact does not stop us from giving imprecise characterizations of these contents through natural language. In this paper, I develop an account of the precision of content characterizations by appealing to possible-world semantics combined with set and measurement theory.

In this first part of a two-part response, we defend the selected effects (SE) theory of biological function against recent critiques by Dong and Piccinini. Challenging the claim that SE theory cannot accommodate novel mutations or artifacts, the authors argue that selection is inescapable for understanding function. They show that even novel traits often emerge from lineages with established functions and that artifacts can be integrated into SE accounts via intentional design and derived functions. Ultimately, we conclude that no compelling (...) reason has been given to abandon or rethink the selected effects approach. (shrink)

In this first part of a two-part response, we respond to Dong and Piccinini’s goal-contribution account (GCA) by arguing that it fails to adequately capture what makes something a function. As we see it, the core problem is that GCA ignores the role of past selection. Without reference to selection history, GCA struggles to distinguish functions from mere effects, especially in cases involving novel traits, dysfunction, or systemic breakdowns. We show that these challenges can be met by acknowledging the inescapability (...) of past selection—even if we want to remain open to pluralist uses of “function” in science. In the end, we propose a new framework—the blueprint account—which integrates intuitions from causal role, organizational, and selection-based theories. While we may want to rethink how we talk about functions, we argue that any viable account will still need to take selection seriously. (shrink)

In her book “Are Mental Disorders Brain Disorders?” (2022), Anneli Jefferson proposes that brain processes that always realize mental dysfunctions are brain dysfunctions. This paper explores possible interpretations of two underdeveloped aspects of this thesis. First, it argues that “realization” should be interpreted as partial rather than full realization. Second, it argues that the “always” should only quantify over biologically normal situations. Taken together, these changes can account for the fact that some psychological dysfunctions are partially realized by functional mechanisms, (...) for the existence of psychological dysfunctions due to mismatches rather than brain dysfunctions, and for the fact that brain dysfunctions do not cease to be brain dysfunctions just because they can be compensated.

Even though the talk of causal bases is commonplace in traditional and contemporary discussions about dispositions, the concept of causal bases has never been systematically investigated. This paper aims to fill this gap by developing the causal-grounding account. This account takes two roles as definitory for causal bases. First, causal bases are possible causes of disposition manifestations. Second, causal bases are metaphysical grounds of disposition instantiations. In this paper, we show that the causal-grounding account (CGA) achieves crucial distinctions (for example (...) between causal bases and manifestation conditions), captures relevant traditional features of causal bases, and can be invoked to support the causal efficacy of disposition instantiations. At the same time, CGA does not require that causal bases have to be categorical or intrinsic. This, in turn, allows us to remain neutral concerning fundamental properties, the existence of dispositional or extrinsic causal bases, multi-track dispositions, and the reducibility of dispositions. This neutrality grants the suitability of our account for different philosophical projects and discussions. (shrink)

In this paper, we explore whether a living being can have a medical disorder purely in virtue of its current structure, or whether its historical origins are also relevant. We do so by presenting two dialogues based on the Swampman thought experiment. These dialogues bring out two key points. First, although evolutionary history plays a central role in theoretical accounts of disorder, its relevance is less obvious in everyday medical practice. Second, there may be an asymmetry between somatic and mental (...) disorders: somatic disorders are typically identified by biological dysfunction, while many paradigmatic mental disorders appear to involve violations of rationality. Nevertheless, we suggest that dysfunctions—and thereby historical considerations—still play a role in distinguishing normal from pathological irrationality. Rather than introducing a new theory, this paper tests existing accounts of function and disorder by applying them to an extreme but instructive case. (shrink)

Ulrich Krohs’ Gehirn und Freiheit entwirft ein Zustandsmodell, das Bewusstsein und Freiheit gemeinsam erklären soll: von mentaler Verursachung über Intentionalität und Selbstbewusstsein bis zu moralischer Verantwortlichkeit. Krohs versteht sein Projekt als einen Beitrag zur materialistischen Lösung des Leib-Seele-Problems. Demnach beruht Psychisches allein auf Physischem. Zugleich vertritt er einen nichtreduktiven Materialismus, da bewusste Gehirnzustände neben physikalischen auch phänomenale und intentionale Eigenschaften besitzen. Als methodologischer Naturalist und Naturphilosoph entwickelt Krohs dieses Modell nicht nur auf Grundlage phänomenologischer Intuitionen und klassischer Probleme der Philosophie (...) des Geistes, sondern vor allem unter Bezugnahme auf psychologische, (neuro-)biologische und physikalische Befunde. In dieser Rezension gebe ich zunächst eine grobe Übersicht über die drei Hauptteile. Anschließend beleuchte ich in zwei Schlaglichtern die Architektur des Zustandsmodells sowie Krohs’ Freiheitsbegriff. (shrink)

Laura Nader is a towering figure as anthropologist, teacher, and public intellectual. Her letters give a glimpse of academic life mostly unseen by academics and by the general public.

Philosophers of quantum mechanics have generally addressed exceedingly simple systems. Laura Ruetsche offers a much-needed study of the interpretation of more complicated systems, and an underexplored family of physical theories, such as quantum field theory and quantum statistical mechanics, showing why they repay philosophical attention. She guides those familiar with the philosophy of ordinary QM into the philosophy of 'QM infinity', by presenting accessible introductions to relevant technical notions and the foundational questions they frame--and then develops and defends answers (...) to some of those questions. Finally, Ruetsche highlights ties between the foundational investigation of QM infinity and philosophy more broadly construed, in particular by using the interpretive problems discussed to motivate new ways to think about the nature of physical possibility and the problem of scientific realism.

In this comprehensive new study of human free agency, Laura Waddell Ekstrom critically surveys contemporary philosophical literature and provides a novel account of the conditions for free action. Ekstrom argues that incompatibilism concerning free will and causal determinism is true and thus the right account of the nature of free action must be indeterminist in nature. She examines a variety of libertarian approaches, ultimately defending an account relying on indeterministic causation among events and appealing to agent causation only in (...) a reducible sense. Written in an engaging style and incorporating recent scholarship, this study is critical reading for scholars and students interested in the topics of motivation, causation, responsibility, and freedom. In broadly covering the important positions of others along with its exposition of the author’s own view, Free Will provides both a significant scholarly contribution and a valuable text for courses in metaphysics and action theory.

The definitions and conceptualizations of health, and the management of healthcare have been challenged by the current global scenarios (e.g., new diseases, new geographical distribution of diseases, effects of climate change on health, etc.) and by the ongoing scholarship in humanities and science. In this paper we question the mainstream definition of health adopted by the WHO-'a state of complete physical, mental and social well-being and not merely the absence of disease or infirmity' (WHO in Preamble to the constitution of (...) the World Health Organization as adopted by the international health conference, The World Health Organization, 1948)-and its role in providing tools to understand what health is in the contemporary context. More specifically, we argue that this context requires to take into account the role of the environment both in medical theory and in the healthcare practice. To do so, we analyse WHO documents dated 1984 and 1986 which define health as 'coping with the environment'. We develop the idea of 'coping with the environment', by focusing on two cardinal concepts: adaptation in public health and adaptivity in philosophy of biology. We argue that the notions of adaptation and adaptivity can be of major benefit for the characterization of health, and have practical implications. We explore some of these implications by discussing two recent case studies of adaptivity in public health, which can be valuable to further develop * Laura Menatti. (shrink)

The Victorian period in Britain was an “age of reform.” It is therefore not surprising that two of the era’s most eminent intellects described themselves as reformers. Both William Whewell and John Stuart Mill believed that by reforming philosophy—including the philosophy of science—they could effect social and political change. But their divergent visions of this societal transformation led to a sustained and spirited controversy that covered morality, politics, science, and economics. Situating their debate within the larger context of Victorian society (...) and its concerns, _Reforming Philosophy_ shows how two very different men captured the intellectual spirit of the day and engaged the attention of other scientists and philosophers, including the young Charles Darwin. Mill—philosopher, political economist, and Parliamentarian—remains a canonical author of Anglo-American philosophy, while Whewell—Anglican cleric, scientist, and educator—is now often overlooked, though in his day he was renowned as an authority on science. Placing their teachings in their proper intellectual, cultural, and argumentative spheres, Laura Snyder revises the standard views of these two important Victorian figures, showing that both men’s concerns remain relevant today. A philosophically and historically sensitive account of the engagement of the major protagonists of Victorian British philosophy, _Reforming Philosophy_ is the first book-length examination of the dispute between Mill and Whewell in its entirety. A rich and nuanced understanding of the intellectual spirit of Victorian Britain, it will be welcomed by philosophers and historians of science, scholars of Victorian studies, and students of the history of philosophy and political economy.

Este ensayo analiza los riesgos y encrucijadas a que se enfrentan los distintos discursos feministas de un tiempo a esta parte. Es difícil sustraerse tanto a la tentación del victimismo como a la de una historia monumentalista de grandes heroínas, y también resulta complicado evitar pensar en una esencia femenina constituida y atravesada por unos «patrones de dominación», en palabras de Simone de Beauvoir. Más allá de códigos, prejuicios y dogmas, el libro de Laura Llevadot establece un ilustrador mapa (...) del feminismo contemporáneo, se enfrenta a las trampas de un lenguaje heredado que nos impide pensar por cuenta propia y, finalmente, nos impulsa a «desnaturalizar» cuanto de artificial y construido hay en la diferencia sexual.

Insights into the intelligence throughout the natural and technical environment, in the fabric of our devices and dwellings, in our clothes, and under our skin. Is there a way to understand the materials that surround us not as passive objects, but as other intelligences interacting with our own? In Parallel Minds, expert in materials science and nanotechnology Laura Tripaldi delivers not only detailed insights into the properties and emergent behaviors of matter as revealed by state-of-the-art chemistry, synthetic biology, and (...) nanotech, but also a rich philosophical reflection that crosses the frontier between nature and culture, where the most cutting-edge scientific syntheses resonate with ancient myth. The result is a technomaterial bestiary full of unexpected encounters with “strange minds”—from cobwebs to kevlar and carbon fibre, from centaurs to amoebas to arachnids, from polycephalic slime to resonating plasmons, from viruses to golems. Parallel Minds reveals the intelligence at large throughout the natural and technical environment, in the fabric of our devices and dwellings, in our clothes, and even under our skin. Full of lateral ideas and unexpected images, Tripaldi’s book imbues the study and synthesis of materials with a new urgency. For not only do the materials that surround us participate actively in the construction of the world in which we live, but harnessing their ability to interact intelligently with their environment could be the key to the future of our species.

In this paper the exclusive focus on large firms in the field of business ethics is challenged. Some of the idiosyncrasies of small firms are explained, and links are made between these and potential ethical issues. A review of the existing literature on ethics in small firms demonstrates the lack of appropriate research, so that to date we can draw no firm conclusions in relation to ethics in the small firm. Recommendations are made as to the way forward for small (...) firm business ethics research. Questions for investigation are suggested using micro, meso and macro perspectives. Much exploratory work needs to be done to lay the groundwork for this important area of social and commercial research in the future. (shrink)

This innovative book takes a new look at environmental ethics and the need for ecological and biological integrity. Laura Westra explores the necessity for radical alteration not only of interpersonal ethics, but also of social institutions and public policy. In the process, Westra denies the validity of majority rule in environmentally ethical concerns. Issues discussed in the book include the link between ecological integrity and human health; an environmental evaluation of business and technology; biotechnology and transgenics in agriculture and (...) aquaculture; and the environmental ethics of the ancient Greeks and Kant. Living in Integrity is a valuable book for philosophers and environmentalists alike. (shrink)

Laura Berchielli - Color, Space and Figure in Locke: An Interpretation of the Molyneux Problem - Journal of the History of Philosophy 40:1 Journal of the History of Philosophy 40.1 47-65 Color, Space, and Figure in Locke: An Interpretation of the Molyneux Problem Laura Berchielli THIS IS HOW LOCKE, in the second edition of his Essay Concerning Human Understanding, introduces a question that had been suggested to him in a letter from William Molyneux:... I shall here insert a (...) Problem of that very Ingenious and Studious promoter of Knowledge, the Learned and Worthy Mr. Molineux, which he was pleased to send me in a Letter some Months since; and it is this: Suppose a Man born blind, and now adult, and taught by his touch to distinguish between a Cube, and a Sphere of the same metal, and nighly of the same bigness, so as to tell, when he felt one and t'other, which is the Cube, which the Sphere. Suppose then the Cube and Sphere placed on a Table, and the Blind Man to be made to see. Quaere, Whether by his Sight, before he touch'd them, he could now distinguish, and tell, which is the Globe, which the Cube. In the standard interpretation of the Molyneux problem as presented in Locke, the question is always linked to the general issue of differences in the ideas of figure received by the various senses. This interpretation -- put forward by Berkeley --says that for Locke, the ideas of figure produced by sight are specifically different from.. (shrink)

This paper presents a conception of the self partially in terms of a particular notion of preference.

Deep brain stimulation is a well-accepted treatment for movement disorders and is currently explored as a treatment option for various neurological and psychiatric disorders. Several case studies suggest that DBS may, in some patients, influence mental states critical to personality to such an extent that it affects an individual’s personal identity, i.e. the experience of psychological continuity, of persisting through time as the same person. Without questioning the usefulness of DBS as a treatment option for various serious and treatment refractory (...) conditions, the potential of disruptions of psychological continuity raises a number of ethical and legal questions. An important question is that of legal responsibility if DBS induced changes in a patient’s personality result in damage caused by undesirable or even deviant behavior. Disruptions in psychological continuity can in some cases also have an effect on an individual’s mental competence. This capacity is necessary in order to obtain informed consent to start, continue or stop treatment, and it is therefore not only important from an ethical point of view but also has legal consequences. Taking the existing literature and the Dutch legal system as a starting point, the present paper discusses the implications of DBS induced disruptions in psychological continuity for a patient’s responsibility for action and competence of decision and raises a number of questions that need further research.

Moods have global and profound effects on our thoughts, motivations and behavior. To understand human behavior and cognition fully, we must understand moods. In this paper I critically examine and reject the methodology of conventional ?cognitive theories? of affect. I lay the foundations of a new theory of moods that identifies them with processes of our cognitive functional architecture. Moods differ fundamentally from some of our other affective states and hence require distinct explanatory tools. The computational theory of mood I (...) propose places them within the context of other mental phenomena and is consistent with the empirical data on moods. (shrink)

Over email a few days after the death of Daniel Callahan, cofounder of The Hastings Center and for many years its director and then president, Joseph Fins, a longtime Hastings colleague, offered this comfort: “[H]enceforth every issue of the Report is a living memorial to Dan the writer, editor, and institution builder.” In the Hastings Center Report's first issue, published in June 1971, Dan stated, “To say that [the work of the Report] must be multi‐disciplinary is only to say the (...) issues [it will address] are as complex as human beings themselves.” This July–August 2019 issue continues the tradition Dan began.

What does it take to count as competent with the meaning of a thin evaluative predicate like 'is the right thing to do'? According to minimalists like Allan Gibbard and Ralph Wedgwood, competent speakers must simply use the predicate to express their own motivational states. According to analytic descriptivists like Frank Jackson, Philip Pettit and Christopher Peacocke, competent speakers must grasp a particular criterion for identifying the property picked out by the term. Both approaches face serious difficulties. We suggest that (...) these difficulties derive from a shared background assumption that competence conditions must be explained in terms of a determinate conceptual role. We propose a new way of characterizing competence with evaluative terms: what's required for competence is participation in a shared epistemic practice with a term. Our approach, we argue, better explains the nature of evaluative inquiry and the extent of disagreement about evaluative questions. (shrink)

Anti-individualists claim that concepts are individuated with an eye to purely external facts about a subject's environment about which she may be ignorant or mistaken. This paper offers a novel reason for thinking that anti-individualistic concepts are an ineliminable part of commonsense psychology. Our commitment to anti-individualism, I argue, is ultimately grounded in a rational epistemic agent's commitment to refining her own representational practices in the light of new and surprising information about her environment. Since anti-individualism is an implicit part (...) of responsible epistemic practices, we cannot abandon it without compromising our own epistemic agency. The story I tell about the regulation of one's own representational practices yields a new account of the identity conditions for anti-individualistic concepts. (shrink)

Molecular biologists and biochemists often use diagrams to present hypotheses. Analysis of diagrams shows that their content can be expressed with linguistic representations. Why do biologists use visual representations instead? One reason is simple comprehensibility: some diagrams present information which is readily understood from the diagram format, but which would not be comprehensible if the same information was expressed linguistically. But often diagrams are used even when concise, comprehensible linguistic alternatives are available. I explain this phenomenon by showing why diagrammatic (...) representation is especially well suited for a particular kind of explanation common in molecular biology and biochemistry: namely, functional analysis, in which a capacity of the system is explained in terms of capacities of its component parts.

It's generally agreed that, for a certain a class of cases, a rational subject cannot be wrong in treating two elements of thought as co-referential.

: Although "brain death" and the dead donor rule—i.e., patients must not be killed by organ retrieval—have been clinically and legally accepted in the U.S. as prerequisites to organ removal, there is little data about public attitudes and beliefs concerning these matters. To examine the public attitudes and beliefs about the determination of death and its relationship to organ transplantation, 1351 Ohio residents ≥18 years were randomly selected and surveyed using random digit dialing (RDD) sample frames. The RDD telephone survey (...) was conducted using computer-assisted telephone interviews. The survey instrument was developed from information provided by 12 focus groups and a pilot study of the questionnaire. Three scenarios based on hypothetical patients were presented: "brain dead," in a coma, or in a persistent vegetative state (PVS). Respondents provided personal assessments of whether the patient in each scenario was dead and their willingness to donate that patient's organs in these circumstances. More than 98 percent of respondents had heard of the term "brain death," but only one-third (33.7%) believed that someone who was "brain dead" was legally dead. The majority of respondents (86.2%) identified the "brain-dead" patient in the first scenario as dead, 57.2 percent identified the patient in a coma as dead (Scenario 2), and 34.1 percent identified the patient in a PVS as dead (Scenario 3). Nearly one-third (33.5%) were willing to donate the organs of patients they classified as alive for at least one scenario, in seeming violation of the dead donor rule. Most respondents were not willing to violate the dead donor rule, although a substantial minority was. However, the majority of respondents were unaware, misinformed, or held beliefs that were not congruent with current definitions of "brain death." This study highlights the need for more public dialogue and education about "brain death" and organ donation. (shrink)

Scientists typically use a variety of representations, including different kinds of figures, to present and defend hypotheses. In order to understand the justification of scientific hypotheses, it is essential to understand how visual representations contribute to scientific arguments. Since the logical understanding of arguments involves the truth or falsity of the representations involved, visual representations must have the capacity to bear truth in order to be genuine components of arguments. By drawing on Goodman's analysis of symbol systems, and on Tarski's (...) work on truth, I show that the figures used in science meet this criterion. (shrink)
