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)

According to the Incommensurability Thesis (IT) superseding scientific theories (paradigms) are incommensurable. Unlike many authors we do not discuss whether there is a relationship of this kind. We take for granted that this may be the case, and see the problem in the endeavour to establish the domain of validity of the IT. The notion incommensurability (Ic) is derivative from the concepts of scientific paradigm (P) and scientific revolution (R). There are several concepts of P, as well as various conceptions (...) of R. The Ic concept also has more than one meaning. The validity of the IT is restricted to a subset of P, R, and Ic. From the viewpoint of P this may be the case with (a) substantially different competing general conceptions not reformulated with a view to make them comparable, as well as with (b) scientific communities dogmatically committed to such conceptions. From the viewpoint of R this takes place when we have to do with big revolutions, i.e. superseding conceptions with prevailing discontinuity. Lastly, from the point of view of Ic proper: when it is meant a weak Ic, i.e. a particular incomparability (incompatibility) between the conceptions in question. (shrink)

Measurement is said to be the basis of exact sciences as the process of assigning numbers to matter (things or their attributes), thus making it possible to apply the mathematically formulated laws of nature to the empirical world. Mathematics and empiria are best accorded to each other in laboratory experiments which function as what Nancy Cartwright calls nomological machine: an arrangement generating (mathematical) regularities. On the basis of accounts of measurement errors and uncertainties, I will argue for two claims: 1) (...) Both fundamental laws of physics, corresponding to ideal nomological machine, and phenomenological laws, corresponding to material nomological machine, lie, being highly idealised relative to the empirical reality; and also laboratory measurement data do not describe properties inherent to the world independently of human understanding of it. 2) Therefore the naive, representational view of measurement and experimentation should be replaced with a more pragmatic or practice-based view.

Epistemic relativism rejects the idea that claims can be assessed from a universally applicable, objective standpoint. It is greatly disdained because it suggests that the real ‘basis’ for our views is something fleeting, such as ‘‘the techniques of mass persuasion’’ (Thomas Kuhn 1970) or the determination of intellectuals to achieve ‘‘solidarity’’ (Rorty 1984) or ‘‘keep the conversation going’’ (Rorty 1979). But epistemic relativism, like skepticism, is far easier to despise than to convincingly refute, for two main reasons. First, its definition (...) is unclear, so we cannot always tell where relativism leaves off and other views, such as skepticism or subjectivism, begin. Consequently, it can be difficult to tell when a criticism has done enough. Second, the grounds for relativism are unclear, which can make it hard to know how to attack it or whether we have dismantled all of the ways of supporting it. (shrink)

The article outlines a general epistemological theory of argument: a theory that regards providingjustified belief as the principal aim of argumentation, and defends it instrumentalistically. After introducing some central terms of such a theory, answers to its central questions are proposed: the primary object and structure of the theory, the function of arguments, which is to lead to justified belief, the way such arguments function, which is to guide the addressee's cognizing, objective versus subjective aspects of argumentation, designing different types (...) of argument. Then the notion of ' valid argument' is defined and criteria for the adequate use of such arguments are introduced. Finally, this conception is justified as, among others, leading to more true beliefs than competing conceptions. (shrink)

This paper develops a version of the self-refutation argument against relativism in the teeth of the prevailing response by relativists: that this argument begs the question against them. It is maintained that although weaker varieties of relativism are not self-refuting, strong varieties are faced by this argument with a choice between making themselves absolute (one thing is absolutely true - relativism); or reflexive (relativism is 'true for' the relativist). These positions are in direct conflict. The commonest response, Reflexive Relativism, is (...) shown to be vulnerable to an iterated version of the self-refutation argument. As a result, Reflexive Relativism possesses only the appearance of content, being either incoherent, or a regressively disguised version of Absolute Relativism. Concluding remarks on Absolute Relativism acknowledge this to be a bare, formal possibility, but claim that in fact it must represent one of a range of weaker varieties of relativism that alone remain tenable.

Since the 80s, educators have supported instruction in critical thinking as “an Educational Ideal.” This should not be a surprise given some of the more common conceptions, e.g., Ennis’s “reasonable reflective thinking on what to believe or do,” or Siegel’s “being appropriately moved by reasons,” as opposed to bias, emotion or wishful thinking. Who would want a doctor, lawyer, or mechanic who could not skillfully evaluate arguments, causes, and cures? So, educators endorsed the dream that, through proper CT instruction, students’ (...) critical skills and “rational passions” could be greatly improved. In spite of the dream’s appeal, the reality is, after 30+ years, there is little reason to think the dream resembles reality. After describing what I take to be an adequate definition of CT, such a depressing conclusion will be supported by CT assessment scores from across academe, the continued widespread disagreement among experts in nearly all fields, including CT, and the abundant psychological research on rationality and decision making. And finally, while the ideal extols the value of objectivity, I shall argue that bias may be unavoidable because personal values play a vital role in the evaluation of many arguments. (shrink)

An ideal of education is to ensure that our children develop into autonomous critical thinkers. The ‘indoctrination objection’, however, calls into question whether education, aimed at cultivating autonomous critical thinkers, is possible. The core of the concern is that since the young child lacks even modest capacities for assessing reasons, the constituent components of critical thinking have to be indoctrinated if there is to be any hope of the child's attaining the ideal. Our primary objective is to defuse this objection. (...) We argue, first, that even if the indoctrination objection can be dealt with at the level of beliefs by an account that distinguishes between beliefs instilled in the child at the non‐rational stage that are indoctrinative and those that are non‐indoctrinative, there can be non‐autonomous ‘proto critical thinkers’ who lack autonomy with respect to the requisite motivational components. We then ask what must be added to the account to ensure that proto critical thinkers develop into autonomous ones. We suggest that motivational elements, even if instilled at a stage at which the child has insufficiently developed cognitive capacities, can be ‘truly the child's own’ only relationally: the autonomous motivational elements are ones with respect to which the future child is self‐governing.

Keywords: W.V.Quine claimed that relativism is paradoxical and unacceptable; nevertheless, his own views concerning truth and the underdetermination of theories by data amount to an interesting and plausible form of relativism.

This is a collection of my essays in the philosophy of science which have been translated into Spanish.

In the present paper, I try to defend a coherent interpretation of Goodman’s relativism by responding to the main objections of the critics. I also discuss the significance of his pluralism by relating it to the notion of construction. This will show the relevance of Goodman’s philosophy for the present days.

The article develops and justifies, on the basis of the epistemological argumentation theory, two central pieces of the theory of evaluative argumentation interpretation: 1. criteria for recognizing argument types and 2. rules for adding reasons to create ideal arguments. Ad 1: The criteria for identifying argument types are a selection of essential elements from the definitions of the respective argument types. Ad 2: After presenting the general principles for adding reasons (benevolence, authenticity, immanence, optimization), heuristics are proposed for finding missing (...) reasons, for deductive arguments, e.g., semantic tableaux are suggested.
