Judgment is central to engineering, medicine, the sciences and many other practical activities. For example, one who otherwise knows what engineers know but lacks engineering judgment may be an expert of sorts, a handy resource much like a reference book or database, but cannot be a competent engineer. Though often overlooked or at least passed over in silence, the central place of judgment in engineering, the sciences, and the like should be obvious once pointed out. It is important here because (...) it helps to explain where ethics fits into these disciplines. There is no good engineering, no good science, and so on without good judgment and no good judgment in these disciplines without ethics. Doing even a minimally decent job of teaching one of these disciplines necessarily includes teaching its ethics; teaching the ethics is teaching the discipline (or at least a large part of it).

This paper argues that when used judiciously Bayes's law has a role to play in the evaluation of scientific hypotheses. Several examples are presented in which a rational response to evidence requires a judgement whether to apply Bayes's law or whether, for example, to redistribute prior probabilities. The paper concludes that reflection on Bayes's law illustrates how an adequate account of the rational evaluation of hypotheses requires an account of judgement--a point which several philosophers have noted despite few attempts to (...) develop an adequate theory of judgement.

The author's starting point is Bobbio's theoretical approach to the problems of the relations between law and reason. He then appraises the meanings of reason and the concept of theoretical and practical rationality in the application of law. He examines the complex problem of the rationality of legislation and distinguishes five levels of rationality.

Das Thema dieses Bandes ist die Frage, ob die Wissenschaftstheorie eine normative Disziplin ist. Zunächst überrascht die Frage, denn für viele Wissenschaftstheoretiker ist die Antwort ein klares „Ja“; sie halten es für einen Allgemeinplatz, dass die Wissenschaftstheorie ein normatives Unternehmen ist. Bei genauerem Hinsehen stellt sich jedoch heraus, dass die Frage unterschiedliche Interpretationen zulässt, die einzeln diskutiert werden müssen. Dies geschieht im ersten Abschnitt. Im zweiten Abschnitt suchen wir nach möglichen Erklärungen dafür, warum die Wissenschaftstheorie bisher bei dem Projekt, eine (...) allseits akzeptable Methodologie wissenschaftlichen Schließens zu formulieren und zu begründen, so wenig Erfolg hatte. Eine mögliche Erklärung für den ausbleibenden Erfolg ist der Partikularismus, wonach Methoden keine allgemeine, sondern nur eine lokale, bereichsabhängige Gültigkeit haben. Im dritten Abschnitt wollen wir an Hand des Bayesianismus zeigen, dass die Methodologie doch nicht so schlecht da steht, wie es zunächst den Anschein hat. Der Bayesianismus ist für viele Wissenschaftstheoretiker der aussichtsreichste Kandidat für eine allgemeine Theorie induktiven Räsonierens. Wir besprechen seine Vorzüge, stellen aber auch dar, welche Konzessionen er an den Partikularismus machen muss. (shrink)

Religious naturalism encompasses thinkers from Baruch Spinoza, George Santayana, John Dewey, Henry Nelson Wieman, and Ralph Burhoe to recent writers. I offer a generic definition of religious naturalism and then outline my own version, the “minimalist vision of transcendence.” Many standard issues in the science‐and‐religion dialogue are seen to fade in significance for religious naturalism. I make suggestions for our understanding of science, including the importance of transcognitive abilities, the need for a revised notion of rationality as an alternative to (...) extreme versions of postmodernism, the value of rational dissensus, and the education of appreciation. Finally, I suggest ways to interpret the religious traditions of the world by religious naturalism. (shrink)

What is required for one thing to be a reason for another? Must the reason, more precisely, be or involve a principle? In this essay I target the idea that justification via reasons of one's beliefs (e.g., epistemic or moral) requires that the 'justifying reasons' be or involve (substantive and significant) principles. I identify and explore some potential sources of a principles requirement, and conclude that none of them (i.e., the normative function of reasons, the abstract structure of reasons, the (...) universalizability constraint on [moral] reasons, and even the pragmatic considerations that attenuate 'real-world' reason-giving) mandate that reasons be principles. I then explore implications of this conclusion, and note especially the resultant and paradoxical permissibility of justifying reasons that manage to be lawlike (a sine qua non for justifying reasons) even while consisting of highly-detailed and situation-specific proposition sets, e.g., novel-length narratives.

Critique of instrumental accounts of epistemic rationality.

I take pseudoscience to be a pretence at science. Pretences are innumerable, limited only by our imagination and credulity. As Stove points out, ‘numerology is actually quite as different from astrology as astrology is from astronomy’ (Stove 1991, 187). We are sure that ‘something has gone appallingly wrong’ (Stove 1991, 180) and yet ‘thoughts…can go wrong in a multiplicity of ways, none of which anyone yet understands’ (Stove 1991, 190). Often all we can do is give a careful description of (...) a way of pretending, a motivation for pretence, a source of pretension. In this chapter I attempt the latter. We will be concerned with the relation of conviction to rational belief. I shall be suggesting that the question of whether an enquiry is a pretence at science can be, in part, a question over the role of conviction in rational belief, and that the answer is to be found in the philosophical problem of the role of values in rational belief. (shrink)

This paper introduces a model for evidence denial that explains this behavior as a manifestation of rationality and it is based on the contention that social values (measurable as utilities) often underwrite these sorts of responses. Moreover, it is contended that the value associated with group membership in particular can override epistemic reason when the expected utility of a belief or belief system is great. However, it is also true that it appears to be the case that it is still (...) possible for such unreasonable believers to reverse this sort of dogmatism and to change their beliefs in a way that is epistemically rational. The conjecture made here is that we should expect this to happen only when the expected utility of the beliefs in question dips below a threshold where the utility value of continued dogmatism and the associated group membership is no longer sufficient to motivate defusing the counter-evidence that tells against such epistemically irrational beliefs. (shrink)

Following Nancy Cartwright and others, I suggest that most (if not all) theories incorporate, or depend on, one or more idealizing assumptions. I then argue that such theories ought to be regimented as counterfactuals, the antecedents of which are simplifying assumptions. If this account of the logic form of theories is granted, then a serious problem arises for Bayesians concerning the prior probabilities of theories that have counterfactual form. If no such probabilities can be assigned, the the posterior probabilities will (...) be undefined, as the latter are defined in terms of the former. I argue here that the most plausible attempts to address the problem of probabilities of conditionals fail to help Bayesians, and, hence, that Bayesians are faced with a new problem. In so far as these proposed solutions fail, I argue that Bayesians must give up Bayesianism or accept the counterintuitive view that no theories that incorporate any idealizations have ever really been confirmed to any extent whatsoever. Moreover, as it appears that the latter horn of this dilemma is highly implausible, we are left with the conclusion that Bayesianism should be rejected, at least as it stands. (shrink)

The article protests against the usage of ethical codes by business organisations. It asserts that professionals are in a different situation to that of employees; and that with the latter ethical codes are used by management to ensure compliance and are devoid of ethical content. Ethical codes it is argued are part of management's control system in a time of flatter organisational structures with a far wider span of control. It is also asserted that the ambitions of some to utilise (...) ethical codes so that the business organisation is able to engender societal change is dangerous and likely, if successful, to return us to an age which we could not seriously desire to re-visit.

We argue that new meta-theoretically based applications of non-traditional perspectives of knowledge in science, and sport science, that highlights the question of ‘being woman’, and our understanding of woman as a social and biological being through sport, can enrich the general understanding of gender, identity, body and sport by developing and deepening a critical humanistic sport science perspective through athletes’ artistic reflections of their own athletic female body.

The paper presents a realist account of the epistemic objectivity of science. Epistemic objectivity is distinguished from ontological objectivity and the objectivity of truth. As background, T.S. Kuhn’s idea that scientific theory-choice is based on shared scientific values with a role for both objective and subjective factors is discussed. Kuhn’s values are epistemologically ungrounded, hence provide a minimal sense of objectivity. A robust account of epistemic objectivity on which methodological norms are reliable means of arriving at the truth is presented. (...) The problem remains that deliberative judgement is required to determine the relevance and relative significance of a range of methodological norms. A role is sketched for cognitive virtues which may be exercised in the course of the deliberative judgement. (shrink)

The paper explores the relativistic implications of the thesis of incommensurability. A semantic form of incommensurability due to semantic variation between theories is distinguished from a methodological form due to variation in methodological standards between theories. Two responses to the thesis of semantic incommensurability are dealt with: the first challenges the idea of untranslatability to which semantic incommensurability gives rise; the second holds that relations of referential continuity eliminate semantic incommensurability. It is then argued that methodological incommensurability poses little risk (...) to the rationality or objectivity of science. For rational theory choice need neither be dictated by an algorithm nor governed by a binding set of rules. The upshot of the discussion is deflationary. There is little prospect for a relativistic conception of science based on inflated claims about the incommensurability of scientific theories. (shrink)

This paper defends two principles of methodological conservatism on the grounds that they help to promote an effective social structure for a knowledge‐seeking community. Conservatism has some prima facie justification because it provides for an effective division of cognitive labor, it promotes the effective use of scientific resources, and it provides for a certain amount of stability. However, the principles I defend in this paper should not be treated as absolute or unconditional criteria of theory‐choice, since they can be overridden (...) by other rules or maxims. Since the decision to override a principle of conservatism depends on various contextual factors, the appropriateness of conservatism can vary from context to context. (shrink)

There is a very plausible principle of the transitivity of justifying reasons. It says that if "p" is better justified than "q" (all things considered) and "q" better than "r", then "p" is better justified than "r" (all things considered). There is a corresponding principle of rational theory choice. Call one theory "a better theory than" another theory if all criteria of theory choice considered (explanatory power, simplicity, empirical adequacy, etc.), the first theory meets the criteria better than the second (...) theory. The corresponding transitivity principle says that if theory A is a better theory than theory B and if theory B is a better theory than theory C, then A is a better theory than theory C. I argue against this principle. It turns out that whenever there are 2 or more relevant and independent criteria of theory evaluation, and whenever at least of one the criteria is "non-linear" in a certain sense, there may be violations of transitivity which do not violate any standards of rationality (of theory choice). This shows, again, that theory choice cannot be seen as merely the application of given rules of rational theory choice. (shrink)

This paper articulates and defends a novel view of the strict distinction that Aristotle makes between human and non-human mental life. We examine two crucially relevant but overlooked arguments that turn on the human capacity for reasoning and inference (syl/logismos) to reconstruct his view of what makes some cognitive processes rational and how they differ from non-rational counterparts. A creature is rational just in case its occurrent cognitive states exhibit a sequential coherence wherein prior cognitive activity constrains subsequent activity for (...) the sake of attaining truth. Processes are rational, then, in virtue of how constituent states relate to each other, not whether any given state involves some peculiar content or grasps some distinct object. This study aids, but does not exhaust, a systematic examination of the rational soul in Aristotle’s writing, based on (a) the human/animal comparisons through which he often elucidates rational cognitive capacities and (b) the distinctions that he draws between elements of rational cognition and non-rational counterparts in terms of what minimally suffices to distinguish between them.

In an Isis 2008 review of research in History and Philosophy of Science (HPS), Galison opened discussion on ten on-going HPS problems. It is however unclear to what extent these problems, and constraints on their solutions, are of HPS’s own making. Recent research provides a basic resolution of these issues. In a recent paper Hooker (Perspect Sci 26(2): 266–291, 2018b) proposed that the discipline(s) of HPS should themselves also be understood to employ paradigms in HPS to understand science, analogously to (...) those employed in science to understand scientific domains. The paper argued for recognising at least two paradigms, one based on logic, and analytic forms more generally, the other based on deliberative judgement making. The present paper aims to use paradigmatic responses to Galison’s problems to explore the differing natures, merits and limitations of these two paradigms. This exploration also reveals the basic inadequacy of the analytic paradigm to illuminate the conduct of science, thereby permitting many of his problems to be dissolved rather than solved. (shrink)

The point of this paper is to provide a principled framework for a naturalistic, interactivist-constructivist model of rational capacity and a sketch of the model itself, indicating its merits. Being naturalistic, it takes its orientation from scientific understanding. In particular, it adopts the developing interactivist-constructivist understanding of the functional capacities of biological organisms as a useful naturalistic platform for constructing such higher order capacities as reason and cognition. Further, both the framework and model are marked by the finitude and fallibility (...) that science attributes to organisms, with their radical consequences, and also by the individual and collective capacities to improve their performances that learning organisms display. Part A prepares the ground for the exposition through a critique of the dominant Western analytic tradition in rationalising science, followed by a brief exposition of the naturalist framework that will be employed to frame the construction. This results in two sets of guidelines for constructing an alternative. Part B provides the new conception of reason as a rich complex of processes of improvement against epistemic values, and argues its merits. It closes with an account of normativity and our similarly developing rational knowledge of it, including (reflexively) of reason itself. (shrink)

In his bookMinimal Rationality (1986), Christopher Cherniak draws deep and widespread conclusions from our finitude, and not only for philosophy but also for a wide range of science as well. Cherniak's basic idea is that traditional philosophical theories of rationality represent idealisations that are inaccessible to finite rational agents. It is the purpose of this paper to apply a theory of idealisation in science to Cherniak's arguments. The heart of the theory is a distinction between idealisations that represent reversible, solely (...) quantitative simplifications and those that represent irreversible, degenerate idealisations which collapse out essential theoretical structure. I argue that Cherniak's position is best understood as assigning the latter status to traditional rationality theories and that, so understood, his arguments may be illuminated, expanded, and certain common criticisms of them rebutted. The result, however, is a departure from traditional, formalist theories of rationality of a more radical kind than Cherniak contemplates, with widespread ramifications for philosophical theory, especially philosophy of science itself.

This paper takes as its starting point the observation of quasi-religious, ‘cultural’ characteristics in the dominant discourse of Western liberal democracy, and of ‘ideological’ characteristics in the discourse of Islamism – noting that both discourses rely, to some extent, upon the notion of rationality. Having provided working definitions of rationality, ideology, and culture, it goes on to argue that culture and ideology may be viewed as discursive macro-strategies which are related to the degree of power enjoyed by a given social (...) system at particular historical moments in time: the former being associated with the consolidation of established power and the latter with a bid to acquire power. It suggests that the general function of cultural and ideological strategies is to mask the underlying irrationalities of free-market democracy and Islamism, respectively, and concludes by considering some of the implications of this view in the context of globalization and the ‘war on terror’.

Although typically implicit, clinicians face an inherent conflict between their roles as medical healers and as providers of technical biomedicine (Scott et al. in Philos Ethics Humanit Med 4:11, 2009). This conflict arises from the tension between the physicalist model which still predominates in medical training and practice and the extra-physicalist dimensions of medical practice as epitomised in the concept of patient-centred care. More specifically, the problem is that, as grounded in a "borrowed" physicalist philosophy, the dominant "applied scientist" model (...) exhibits a number of limitations which severely restrict its ability to underwrite the effective practice of care. Moreover, being structural in character, these problems cannot be resolved by piecemeal modifications of the existing model, nor by an appeal to evidence-based medicine (Miles in J Eval Clin Pract 15(6):887-890, 2009; Miles in Folia Med 55(1):5-24, 2013; Miles et al. in J Eval Clin Pract 14(5):621-649, 2008). Hence, the need for medical theorists to "partner with experts in the humanities to build a sui generis philosophy of medicine" (Whatley in J Eval Clin Pract 20(6):961-964, 2014, p. 961). In response, the present paper seeks to vindicate the merits of hermeneutically-informed template in providing the requisite grounding. While capable of correcting for the limitations of the applied scientist model, a hermeneutically-informed template is a "both/and" approach, which seeks to complement rather than exclude the physicalist dimension, and thereby aspires to reconcile technical mastery with patient-centred care, rather than eschew one in favour of the other. As such, it can provide a cogent philosophical template for current best practice, which does justice to the art as well as the science of medical care. (shrink)

While often dubbed “the bible of contemporary psychiatry” and widely hailed as providing “a benchmark” for the profession, on closer inspection the DSM is seen to be shot through with philosophical assumptions that restrict its theoretical cogency and limit it clinical efficacy. Hence, in the interests of enhanced patient-care it is important to think critically about the DSM, with a view to maximising its diagnostic strengths while minimising its weaknesses. The critical analysis undertaken in the present paper underscores the importance (...) of not construing the DSM as a self-contained diagnostic tool but of viewing it, rather, as an indispensable component in a more comprehensive, multidimensional diagnostic process. More specifically, the contention is that the DSM’s diagnostic limitations evoke a biopsychosocial framework of application as their necessary corrective, notwithstanding the entrenched tendency to construe these approaches as oppositional. Further, it is contended that a hermeneutically informed biopsychosocial template has particular advantages as an integrating framework. (shrink)

Philosophical/epistemic theories of rationality differ over the role of judgment in rational argumentation. According to the “classical model” of rationality, rational justification is a matter of conformity with explicit rules or principles. Critics of the classical model, such as Harold Brown and Trudy Govier, argue that the model is subject to insuperable difficulties. They propose, instead, that rationality be understood, ultimately, in terms of judgment rather than rules. In this article I respond to Brown's and Govier's criticisms of the classical (...) model, and to the “judgment model” they propose in its place. I argue that that model is unable both to distinguish between rational and irrational judgment and to avoid recourse to rules, and is therefore inadequate as an account of rationality, critical thinking, or argument appraisal. More positively, I argue that an adequate account of rationality must include a place for both rules and judgment. (shrink)

: This paper is a response to Siegel 2004. I take Siegel's remarks as a basis for clarifying, defending, and further developing my account of the role of judgment in a theory of rationality.

In the literature on dynamical models in cognitive science, two issues have recently caused controversy. First, what is the relation between dynamical and mechanistic models? I will argue that dynamical models can be upgraded to be mechanistic as well, and that there are mechanistic and non-mechanistic dynamical models. Second, there is the issue of explanatory power. Since it is uncontested the mechanistic models can explain, I will focus on the non-mechanistic variety of dynamical models. It is often claimed by proponents (...) of mechanistic explanations that such models do not really explain cognitive phenomena . I will argue against this view. Although I agree that the three arguments usually offered to vindicate the explanatory power of non-mechanistic dynamical models are not enough, I consider a fourth argument, namely that such models provide understanding. The Voss strong anticipation model is used to illustrate this. (shrink)

I examine Thomas Kuhn’s work regarding the role played by the concept of practice in the development of his theory of scientific rationality. I outline the epistemological implications of his theory of incommensurability. I then show how the original intuition of a practice-based and social conception of incommensurability is replaced by a more conventional linguistic interpretation. I then examine Kuhn’s solution to the problem of incommensurability and explain its inadequacy. I then show that, ultimately, his failure to grasp the epistemological (...) dimension of practice prevents him from providing a fully satisfactory solution to the epistemological problem raised in The Structure of Scientific Revolutions.

Discerning the motives that lead businesspeople to make ethical decisions in economic contexts is important, for it aids the moral evaluation of such decisions. But conventional economic theory has for too long assumed an egoist model of motivation, to which many contrast an altruist view of ethical choices. The result is to see business decision making as implying dilemmas. On the other hand, we argue, if one assumes multiple motives, economic and ethical, in ordinary business decisions, a more fruitful model (...) of ethical motivation in such decisions emerges. In this paper multiple motives are assumed to be the norm in a world of large organizations, complex decisions and stakeholder management. An example of a technology acquisition decision, with environmental overtones is presented in illustration of this approach. A method for discerning motives, primarily in terms of behavioural efficacy is presented. On this basis a two step approach to morally evaluating mixed motives in business decisions is proposed. First, the fit of motives with substantive ethical values should be ascertained, and then the efficacy of moral motives in yielding ethical behaviour and outcomes should be determined. This approach, we conclude, offers a much more concrete model of the actual role of moral motives in business decision making. It also signals the importance of moral learning in organizations.

ABSTRACT:The purpose of this paper is to formulate and defend a set of moral principles applicable to management. Our motivation is twofold: 1) to increase the coherence and utility of Integrative Social Contracts Theory (ISCT); and 2) to initiate an alternative stream of business ethics research. To those ends, we specify what counts as adequate guidance in navigating the ethical terrain of business. In doing so, a key element of ISCT, Substantive Hypernorms, is found to be flawed beyond repair. So (...) we propose and defend a remedy:prima faciemoral principles. After delineating the appropriate criteria and format for such principles, we formulate, explain, and defend five of them. We conclude with a brief comment on future research possibilities. (shrink)

Some think that issues to do with scientific method are last century's stale debate; Popper was an advocate of methodology, but Kuhn, Feyerabend, and others are alleged to have brought the debate about its status to an end. The papers in this volume show that issues in methodology are still very much alive. Some of the papers reinvestigate issues in the debate over methodology, while others set out new ways in which the debate has developed in the last decade. The (...) book will be of interest to philosophers and scientists alike in the reassessment it provides of earlier debates about method and current directions of research. (shrink)

Scientific realism is the position that the aim of science is to advance on truth and increase knowledge about observable and unobservable aspects of the mind-independent world which we inhabit. This book articulates and defends that position. In presenting a clear formulation and addressing the major arguments for scientific realism Sankey appeals to philosophers beyond the community of, typically Anglo-American, analytic philosophers of science to appreciate and understand the doctrine. The book emphasizes the epistemological aspects of scientific realism and contains (...) an original solution to the problem of induction that rests on an appeal to the principle of uniformity of nature.

Heuristics are often invoked in the philosophical, psychological, and cognitive science literatures to describe or explain methodological techniques or "shortcut" mental operations that help in inference, decision-making, and problem-solving. Yet there has been surprisingly little philosophical work done on the nature of heuristics and heuristic reasoning, and a close inspection of the way(s) in which "heuristic" is used throughout the literature reveals a vagueness and uncertainty with respect to what heuristics are and their role in cognition. This dissertation seeks to (...) remedy this situation by motivating philosophical inquiry into heuristics and heuristic reasoning, and then advancing a theory of how heuristics operate in cognition. I develop a positive working characterization of heuristics that is coherent and robust enough to account for a broad range of phenomena in reasoning and inference, and makes sense of empirical data in a systematic way. I then illustrate the work this characterization does by considering the sorts of problems that many philosophers believe heuristics solve, namely those resulting from the so-called frame problem. Considering the frame problem motivates the need to gain a better understanding of how heuristics work and the cognitive structures over which they operate. I develop a general theory of cognition which I argue underwrites the heuristic operations that concern this dissertation. I argue that heuristics operate over highly organized systems of knowledge, and I offer a cognitive architecture to accommodate this view. I then provide an account of the systems of knowledge that heuristics are supposed to operate over, in which I suggest that such systems of knowledge are concepts. The upshot, then, is that heuristics operate over concepts. I argue, however, that heuristics do not operate over conceptual content, but over metainformational relations between activated and primed concepts and their contents. Finally, to show that my thesis is empirically adequate, I consider empirical evidence on heuristic reasoning and argue that my account of heuristics explains the data. (shrink)

One of the central tasks of a theory of argumentation is to supply a theory of appraisal: a set of standards and norms according to which argumentation, and the reasoning involved in it, is properly evaluated. In their most general form, these can be understood as rational norms, where the core idea of rationality is that we rightly respond to reasons by according the credence we attach to our doxastic and conversational commitments with the probative strength of the reasons we (...) have for them. Certain kinds of rational failings are so because they are manifestly illogical – for example, maintaining overtly contradictory commitments, violating deductive closure by refusing to accept the logical consequences of one’s present commitments, or failing to track basing relations by not updating one’s commitments in view of new, defeating information. Yet, according to the internal and empirical critiques, logic and probability theory fail to supply a fit set of norms for human reasoning and argument. Particularly, theories of bounded rationality have put pressure on argumentation theory to lower the normative standards of rationality for reasoners and arguers on the grounds that we are bounded, finite, and fallible agents incapable of meeting idealized standards. This paper explores the idea that argumentation, as a set of practices, together with the procedures and technologies of argumentation theory, is able to extend cognition such that we are better able to meet these idealized logical standards, thereby extending our responsibilities to adhere to idealized rational norms.

The thesis proposes an account of the means of scientific representation focused on similarity, or more specifically, on the notion of “creative similarity”. I first distinguish between two different questions regarding the problem of representation: the question about the constituents and the question about the means of representation (following Suárez 2003; van Fraassen 2008). I argue that, although similarity is not a good candidate for constituent of representation, it can satisfactorily answer the question about the means of representation if adequately (...) characterized. To motivate this position, I dispute the main arguments offered against similarity as means of representation, namely the arguments from variety, vagueness, and misrepresentation, and contend that similarity plays a central epistemic role in practices of representing in science. The study of the role of similarity in scientific practice, I argue, requires the analysis of the uses of judgments of similarity in the construction of scientific models. I examine the cases of the Mississippi Basin Model and the San Francisco Bay Model to illustrate how judgments of similarity are directly involved in the production of epistemically fruitful models. Informed by the practical investigation developed throughout the thesis, I finally outline what I call the creative similarity account of the means of representation. The notion of “creative similarity” helps to capture the way in which similarity, as means of representation, intervenes in actual practices of representing, namely, in the form of a productive interplay of judgments of similarity and distortions (i.e. idealizations, abstractions, simplifications), which is employed by resourceful agents with the aim of understanding aspects of the natural world.

Perelman’s discussion about the distinction and relation between the rational and the reason-able could be seen as an attempt to bring forward a new understanding of rationality. In light of the concep-tion of situated reason, this paper argues that Perelman’s explication of the dialectic of the rational and the reasonable highlights the balance of universality and contexuality, and could contribute a fuller conception of rationality to establishing a solid philosophical foundation for Johnson’s informal logic.

There are two chief tasks which confront the philosophy of scientific method. The first task is to specify the methodology which serves as the objective ground for scientific theory appraisal and acceptance. The second task is to explain how application of this methodology leads to advance toward the aim(s) of science. In other words, the goal of the theory of method is to provide an integrated explanation of both rational scientific theory choice and scientific progress.

The topic of this study is to what extent standards of rational inquiry can be rationally criticized and revised. It is argued that it is rational to treat all such standards as open to criticism and revision. Arguments to the effect that we are fallible with regard to all standards of rational inquiry are presented. Standards cannot be ultimately justified and with certainty established either as adequate or as inescapable presuppositions. Apel's attempt to give ultimate justifications of certain moral and (...) logical rules is examined and criticized. Special attention is given to our fallibility with regard to logical inference rules. The idea that certain logical rules cannot be put into question because any critical argument presupposes them is criticized. It has been claimed that there must be some basic standards which are such that they cannot be rationally evaluated and hence are rationally unrevisable. This is called "the unrevisability thesis". Related to this thesis is the normative policy according to which rationality requires that some standards be treated as unrevisable, the unrevisability policy. Two arguments that have been used to defend the unrevisability thesis and policy are examined and criticized. The conclusion is that we are not forced to accept either the thesis or the policy. The negation of the unrevisability policy is the revisability policy, according to which it is rational to treat all standards as open to rational criticism and revision. Objections that have been directed against the revisability policy are discussed and criticized. According to the objections, the revisability policy leads to rationality relativism. These objections are refuted, and it is argued that it is, on the contrary, rational to adopt the revisability policy and treat all standards of rational inquiry as criticizable and revisable. It is proposed that the rational change of standards should be viewed as a bootstrap process. General features of a bootstrap view of rational change of standards are presented, and it is argued that it is impossible to formulate a real theory of bootstrapping. Two models of standard change are presented and discussed: Laudan's reticulated model of scientific rationality and Briskman's bootstrap theory. It is claimed that in spite of defects and limitations, these models contribute to a richer understanding of bootstrapping. The fallibility and revisability of standards of rational inquiry have consequences for how the normativity of rationality should be understood. The book ends with an account of how the rationality of cognitive actions is related to the idea of the adequacy of standards. A distinction between absolute and standard-relative rationality is made, and it is argued that what an inquiring agent rationally ought to do coincides with what it is standard-relatively rational for him to do. It is shown that this view of rationality of inquiry is nevertheless inconsistent with rationality relativism, and that it is compatible with an objectivistic view of rationality. (shrink)
