In a recent exchange, John Worrall and Larry Laudan have debated the merits of the model of rational scientific change proposed by Laudan in his book Science and Values. On the model advocated by Laudan, rational change may take place at the level of scientific theory and methodology, as well as at the level of the epistemic aims of science. Moreover, the rationality of a change which occurs at any one of these three levels may be dependent on considerations at (...) the remaining levels. Yet, in spite of the avowedly anti-relativistic motivation of Laudan's model, Worrall criticizes Laudan for irrevocably relativizing scientific rationality to historically variant methodological standards.

Laudan's normative naturalism' claims to account for the success of science by construing theories and other claims as methodological rules interpreted as defeasible hypothetical imperatives for securing cognitive ends. We ask two questions regarding the adequacy for medicine of Laudan's meta- methodology. First, although Laudan denies that general aims can be assigned to a science, we show that this is not the case for medicine. Second, we argue that Laudan's account yields mixed results as a tool for evaluating methodological rules (...) in medicine. These shortcomings call into question the adequacy of normative naturalism as a meta-methodology for science. (shrink)

In this paper I address some shortcomings in Larry Laudan's normative naturalism. I make it clear that Laudan's rejection of the "meta-methodology thesis", or MMT is unnecessary, and that a reformulated version MMT can be sustained. I contend that a major difficulty that attends Laudan's account is his contention that a naturalistic philosophy of science cannot accommodate any a priori justification of methodological rules, and consider what sort of naturalism might best replace Laudan's. To do this, I discuss Michael Friedman's (...) account of a relativised a priori and show that it is consistent with naturalistic philosophy of science and that it can help form the basis of a plausible normative naturalism. In particular, this Discussion shows that Laudan's rejection of any a priori justification of methodological rules is unjustified and inconsistent with scientific practice. Finally, I point the way to a version of normative naturalism that includes MMT and accounts for the role of constitutive a priori principles within science. (shrink)

We argue for a naturalistic account for appraising scientific methods that carries non-trivial normative force. We develop our approach by comparison with Laudan’s (American Philosophical Quarterly 24:19–31, 1987, Philosophy of Science 57:20–33, 1990) “normative naturalism” based on correlating means (various scientific methods) with ends (e.g., reliability). We argue that such a meta-methodology based on means–ends correlations is unreliable and cannot achieve its normative goals. We suggest another approach for meta-methodology based on a conglomeration of tools and strategies (from statistical modeling, (...) experimental design, and related fields) that affords forward looking procedures for learning from error and for controlling error. The resulting “error statistical” appraisal is empirical—methods are appraised by examining their capacities to control error. At the same time, this account is normative, in that the strategies that pass muster are claims about how actually to proceed in given contexts to reach reliable inferences from limited data.

This paper argues that, as all available accounts of how scientific and non-scientific goals might be distinguished rely upon distinctions as much in need of explication as the notion of scientific goals itself, naturalized accounts of science should reject the notion that there are characteristically scientific goals for a given time and place and instead countenance only the goals which happen to be had by individual scientists or their communities. This argument and the recommendation that follows from it are illustrated (...) by reference to Watson and Crick's discovery of the structure of DNA. (shrink)

In previous work, I defended Larry Laudan against the criticism that the axiological component of his normative naturalism lacks a naturalistic justification. I argued that this criticism depends on an equivocation over the term 'naturalism' and that it begs the question against what we are entitled to include in our concept of nature. In this paper, I generalize that argument and explore its implications for Laudan and other proponents of epistemic naturalism. Here, I argue that a commitment to naturalism in (...) the methods and aims of science inevitably entails a kind of epistemic relativism. However, I argue that this should not be interpreted as a reductio of naturalism, since the admission of contextually based standards and aims of science does not result in quietism when it comes to important questions concerning scientific rationality.

Doppelt (1986,1990), Siegel (1990), and Rosenberg (1996) argue that the pivotal feature of Laudan's normative naturalism, namely his axiology, lacks a naturalistic foundation. In this paper I show that this objection turns on a misunderstanding of Laudan's use of the term 'naturalism'. Specifically, I argue that there are two important senses of naturalism running through Laudan's work. Once these two strands are made explicit, the objection raised by Doppelt and others simply disappears.

Social Epistemology, as formulated by Steve Fuller, is based on the suggestion that rational knowledge policy must be held accountable to ‘brute facts’ about the nature of our human cognitive pursuits, whatever these may be. One difficulty for Fuller concerns the conception of the social which underwrites social epistemology. I argue that social epistemology conflates the social with human psychological properties that are available for public scrutiny and, accordingly, that social epistemology is best viewed as a brand of psychologism. Though (...) Fuller's proposal signifies an important step in the ongoing attempt by scholars to eradicate the last traces of Descartes' epistemological device of a disembodiedres cogitans, I conclude that his conception of the social is too weak to serve as the basis for a socially-embedded discipline in anything but name only.
