Although on opposite sides of the logic of discovery debate, Laudan and Simon share a thesis of divorce between discovery (invention) and justification (appraisal); but unlike some other authors, they do not base their respective versions of the divorce-thesis on the empirical/logical distinction. Laudan argues that, in contemporary science, invention is irrelevant to appraisal, and that this irrelevance renders epistemically pointless the inventionist program. Simon uses his divorce-thesis to defend his account of invention, which he claims to be non-inductive--so evading (...) the problem of induction. Underlying both authors' positions are inadequate conceptions of inductive inference. Laudan here ignores the role in contemporary science of plausibility arguments, which provide a crucial link between invention and appraisal, and thence an epistemic rationale for inventionism. Simon's account of invention does covertly call upon inductive principles from the context of appraisal, and this is what gives his program epistemic import; otherwise he would be vulnerable to Laudan's "no rationale" critique. The tensions in both authors reveal the falsity of the divorce-thesis, and the essential function of induction in both appraisal and invention of hypotheses. (shrink)

Vulnerabilities often characterize the availability of immigrant populations of interest in social behavioral science, public health, and medical research. Refugees, asylum seekers, and undocumented immigrants present unique vulnerabilities relevant to protocol development as well as ethics review procedures and criteria. This paper describes vulnerable populations in relation to the Belmont Report and US federal regulations for the protection of human subjects, both of which are commonly used in international research contexts. It argues for safeguards for immigrants comparable to protections for (...) such populations as pregnant women, prisoners, and children. The paper further presents a two-part model for the review of protocols that involve immigrants. The model is intended to help identify the risks to immigrants associated with participation in research, and to suggest how researchers can responsibly frame studies and access to research participant immigrants through community-based, and/or non-governmental organizations that serve immigrants and immigrant communities.

I argue in this essay that belief/desire explanations are not logically true and not causal, and further that the antecedent of a true belief/desire conditional cannot be strengthened in such a way as to transform it into a true causal statement. I also argue that belief/desire explanations are not dispensable: they are presupposed in our justifications of scientific claims. The proposal is not that psychological determinism is false, but that some at least of our activities are not describable in causal (...) terms. These arguments prepare the ground for a puzzle. If all human intentional behaviour is caused, then all actual linkages between psychological states and behaviour should be expressed in causal statements. But neither the action of asserting a causal statement nor the action of justifying the assertion can be described as the result of a cause. Therefore if one accepts that scientific claims can be justified, not all linkages between psychological states and subsequent action are expressible in causal statements. I do not offer a solution to this puzzle. (shrink)

A formal treatment of the logic of a type of conditional found in natural speech which differs substantially from the material conditional of propositional logic and from the conditionals afforded by theories of possible worlds.
