Epistemic instrumentalism views epistemic norms and epistemic normativity as essentially involving the instrumental relation between means and ends. It construes notions like epistemic normativity, norms, and rationality, as forms of instrumental or means-end normativity, norms, and rationality. I do two main things in this paper. In part 1, I argue that there is an under-appreciated distinction between two independent types of epistemic instrumentalism. These are instrumentalism about epistemic norms and instrumentalism about epistemic normativity. In part 2, I argue that this (...) under-appreciated distinction matters for the debate surrounding the plausibility of EI. Specifically, whether we interpret EI as norm-EI or as source-EI matters for the widely discussed universality or categoricity objection to EI, and for two important motivations for adopting EI, namely naturalism and the practical utility of epistemic norms. I will then conclude by drawing some lessons for epistemic instrumentalism going forward. (shrink) | |
Following David Hitchcock and Stephen Toulmin, this paper takes warrants to be material inference rules. It offers an account of the form such rules should take that is designed (a) to implement the idea that an argument/inference is valid only if it is entitlement preserving and (b) to support a qualitative version of evidence proportionalism. It attempts to capture what gives warrants their normative force by elaborating a concept of reliability tailored to its account of the form such rules should (...) take. (shrink) | |
In The Uses of Argument, Stephen Toulmin proposed a model for the layout of arguments: claim, data, warrant, qualifier, rebuttal, backing. Since then, Toulmin’s model has been appropriated, adapted and extended by researchers in speech communications, philosophy and artificial intelligence. This book assembles the best contemporary reflection in these fields, extending or challenging Toulmin’s ideas in ways that make fresh contributions to the theory of analysing and evaluating arguments.

Critique of instrumental accounts of epistemic rationality. | |
Scientific methods are heuristic in nature. Heuristics are simplifying, incomplete, underdetermined and fallible problem-solving rules that can nevertheless serve certain goals in certain contexts better than truth-preserving algorithms. Because of their goal- and context-dependence, a framework is needed for systematic choosing between them. This is the domain of scientific methodology. Such a methodology, I argue, relies on a form of instrumental rationality. Three challenges to such an instrumentalist account are addressed. First, some authors have argued that the rational choice of (...) at least some methods, namely those supporting belief formation, is not goal-dependent. Second, some authors have observed that some method choices seem intuitively rational, even though relevant goals are lacking. Thirdly, some authors have argued that instrumental rationality itself depends on a goal-independent form of rationality. It is the heuristic nature of scientific methods that affords me the arguments against these challenges. This heuristic-instrumentalist account provides the means-ends analysis needed to evaluate heuristic method choice. The paper thus offers the conceptual basis for a scientific methodology that is both compatible with the heuristic nature of actual scientific practice and also normatively relevant for assessing method choice.

In this paper I reply to Stefaan Cuypers' explication and critique of my views on rationality and critical thinking (Cuypers, 2004). While Cuypers' discussion is praiseworthy in several respects, I argue that it (1) mistakenly attributes to me a Humean view of (practical) reason, and (2) unsuccessfully argues that my position lacks the resources required to defend the basic claim that critical thinking is a fundamental educational ideal. Cuypers' analysis raises deep issues about the motivational character of reasons; I briefly (...) address this matter as well. (shrink) | |
Critical thinking is considered to be a central epistemic aim of education. The claim may be about skills, but also about the state of justified belief. In opposition to this latter view, Alvin Goldman claimed that justification is only a means to true belief and that the only fundamental epistemic aim of education is true belief. Harvey Siegel’s response defended the view that justified belief is in fact a fundamental epistemic aim of education. In a recent article, Alessia Marabini and (...) Luca Moretti analyse Siegel’s arguments, reject all of them, and provide two new ones. I defend one of Siegel’s arguments against their objection, raise some doubts about one of their own arguments, and give an additional argument against Goldman’s view. (shrink) | |
The article presents a critical discussion of Larry Laudan's naturalistic metamethodological theory known as normative naturalism (NN). I examine the strongest extant objection to NN, and, with reference to ideas in Freedman ( Philosophy of Science , 66 (Proceedings), pp. S526-S537, 1999), show how NN survives it. I then go on to outline two problems that really do compromise NN. The first revolves around Laudan's conception of the relationship between scientific values and the history of science. Laudan argues we can (...) make sense of progress in science without seeing great scientists in the past as having held the cognitive values and methodological rules we hold today as important for science. I argue this is extremely implausible, and moreover that Laudan must see our values today as justified by reference to the values of past scientists if he is to avoid a pernicious form of relativism. The second problem with NN is that its conception of methodological rules--as hypothetical imperatives linking cognitive means to ends--is untenable. Such rules would not be needed in a scientific community; moreover it is doubtful whether they should class as rules at all. I conclude by suggesting that the distinction between cognitive means and ends which undergirds Laudan's view is intuitively not well founded, and in any case does not provide sufficient materials for a viable normative naturalized epistemology.

The function of concepts must be taken seriously to understand the scientific practices of developing and working with concepts. Despite its significance, little philosophical attention has been paid to the function of concepts. A notable exception is Brigandt (2010), who suggests incorporating the epistemic goal pursued with the concept’s use as an additional semantic property along with the reference and inferential role. The suggestion, however, has at least two limitations. First, his proposal to introduce epistemic goals as the third component (...) of concepts lacks independent grounding, except to account for the rationality of semantic change (the Grounding Problem). Second, it is hardly justified to consider epistemic goals as a semantic property (the Misplacement Problem). To remedy these predicaments, we suggest a new perspective that takes concepts as cognitive entities with a 2-layered structure rather than as merely linguistic entities and develop an account of the function of concepts. We provide empirical evidence showing that functional information affects our cognitive processes. It is claimed that the function of concepts is not a semantic property but a type of meta-information regulating a body of concept-constitutive information. (shrink) | |

“Naturalized epistemology” is a recent attempt to transform the theory of knowledge into a branch of natural science. Traditional epistemologists object to this proposal on the grounds that it eliminates the distinctively philosophical content of epistemology. In this thesis, I argue that traditional philosophers are justified in their reluctance to accept naturalism, but that their ongoing inability to refute it points to deeper problems inherent in traditional epistemology. I establish my thesis first by critiquing three versions of naturalism, showing that (...) each version either fails to implement its objectives consistently or starts from dubious objectives. “Optimistic naturalism” attempts to use naturalistic methods to give positive answers to traditional epistemological questions (such as by affirming that our beliefs can be justified). This fails because the form of traditional questions requires the concept “belief,” a concept that I argue naturalistic methodology cannot countenance (because of the severe constraints of naturalistic semantic theory). “Pessimistic naturalism,” the version advocated by Quine, is more consistent with naturalistic methodology, but fails because hidden behind its conclusions are assumptions (such as the underdetermination thesis) that cannot themselves be naturalized in the full context of scientific evidence. A final attempt to naturalize epistemology, deflationary naturalism, dispenses with traditional questions entirely, urging that the terms “knowledge” and “justification” be taken as mere pragmatic devices whose use can, nevertheless, be studied scientifically. Curiously, this view fails to take account of important facts about the actual use of those terms, as studied by psychologists. In the end, despite problems with each of these versions, traditional philosophers can learn something from their encounter with naturalism. In the course of showing how various naturalistic doctrines cannot themselves be naturalized, I identify the flaws in traditional epistemology (such as its reliance on a priorism, and its resulting inability to articulate a workable empirical foundationalist theory of justification) that make naturalism harder to challenge. These flaws must be corrected if philosophers are to preserve the autonomy of their discipline. (shrink) | |
Este artículo discute varios modos de entender la racionalidad de la ciencia como racionalidad práctica. En primer lugar, rechaza los modelos instrumentalistas de la racionalidad científica, porque no pueden mostrar la independencia y la bondad de fines definidos para la ciencia, en relación con los cuales se establece la fuerza normativa de las razones. La errónea identificación de fines y valores es lo que provoca numerosas confusiones en este terreno. Se critica, en segundo lugar, un modelo de racionalidad práctica basado (...) en el dominio de saberes tácitos y habilidades. Cualquiera de los modelos propuestos ha de acomodarse a tres restricciones sobre lo que puede ser una "buena razón" dentro de la ciencia y que conforman la identidad práctica y el rostro normativo de la ciencia: publicidad, fiabilidad y autoridad reflexiva. This paper discusses some ways of understanding scientific rationality as practical rationality. Firstly, instrumental models of the rationality of science are rejected. The instrumentalist can hardly establish the independence and goodness of certain ends. In the case of science, determinate ends with respect to which the normative force of our reasons is established do not seem to exist. A false identification of ends with values is what causes many of the confusions. Secondly, a model of practical rationality based in the mastery of tacit knowledge and skills is criticized. Any model of scientific rationality should take into account three constraints about what a "good reason" in scientific matters is, constraints that shape the practical identity and the normative face of science: the constraints of publicity, reliability and reflective authority.
