What exactly is a philosophical intuition? And what makes such an intuition reliable, when it is reliable? This paper provides a terminological framework that is able answer to the first question, and then puts the framework to work developing an answer to the second question. More specifically, the paper argues that we can distinguish between two different "evidential roles" which intuitions can occupy: under certain conditions they can provide information about the representational structure of an intuitor's concept, and under different (...) conditions, they can provide information about whether or not a property is instantiated. The paper describes two principles intended to capture the difference between the two sets of conditions---that is, the paper offers a principle that explains when an intuition will be a reliable source of evidence about the representation structure of an intuitor's concept, and another principle that explains when an intuition will be a reliable source of evidence about whether or not a property is instantiated. The paper concludes by briefly arguing that, insofar as philosophers are interested using intuitions to determine whether or not some philosophically interesting property is instantiated by some scenario (for instance, whether knowledge is instantiated in a Gettier-case), the reliability of the intuition in question does not depend on whether or not the intuition is widely shared.

Evolutionary psychologists often try to “bring together” biology and psychology by making predictions about what specific psychological mechanisms exist from theories about what patterns of behaviour would have been adaptive in the EEA for humans. This paper shows that one of the deepest methodological generalities in evolutionary biology—that proximate explanations and ultimate explanations stand in a many-to-many relation—entails that this inferential strategy is unsound. Ultimate explanations almost never entail the truth of any particular proximate hypothesis. But of course it does (...) not follow that there are no other ways of “bringing together” biology and psychology. Accordingly, this paper explores one other strategy for doing just that, the pursuit of a very specific kind of consilience. However, I argue that inferences reflecting the pursuit of this kind of consilience with the best available theories in contemporary evolutionary biology indicate that psychologists should have a preference for explanations of adaptive behavior in humans that refer to learning and other similarly malleable psychological mechanisms—and not modules or instincts or any other kind of relatively innate and relatively non-malleable psychological mechanism.

We asked college students to make judgments about realistic moral situations presented as dilemmas (which asked for an either/or decision) vs. problems (which did not ask for such a decision) as well as when the situation explicitly included affectively salient language vs. non-affectively salient language. We report two main findings. The first is that there are four different types of cognitive strategy that subjects use in their responses: simple reasoning, intuitive judging, cautious reasoning, and empathic reasoning. We give operational definitions (...) of these types in terms of our observed data. In addition, the four types characterized strategies not only in the whole sample, but also in all of the subsamples in our study. The second finding is that the intuitive judging type comprised approximately 26% of our respondents, while about 74% of our respondents employed one of the three styles of reasoning named above. We think that these findings present an interesting challenge to models of moral cognition which predict that there is either a single, or a single most common, strategy – especially a strategy of relying upon one’s intuitions – that people use to think about moral situations.
