In the rationality debate, Gerd Gigerenzer and his colleagues have argued that human’s apparent inability to follow probabilistic principles does not mean our irrationality, because we can do probabilistic reasoning successfully if probability information is given in frequencies, not percentages (the natural frequency hypothesis). They also offered an evolutionary argument to this hypothesis, according to which using frequencies was evolutionarily more advantageous to our hominin ancestors than using percentages, and this is why we can reason correctly about probabilities in the (...) frequency format. This paper offers a critical review of this evolutionary argument. I show that there are reasons to believe using the frequency format was not more adaptive than using the standard (percentage) format. I also argue that there is a plausible alternative explanation (the nested-sets hypothesis) for the improved test performances of experimental subjects—one of Gigerenzer’s key explananda—which undermines the need to postulate mental mechanisms for probabilistic reasoning tuned to the frequency format. The explanatory thrust of the natural frequency hypothesis is much less significant than its advocates assume. (shrink)

The proliferation of dimensions of appraisal is both welcome and worrying. The preoccupation with sorting out causes may be somewhat otiose. And the ubiquity of emotions in levels of processing raises intriguing problems about the role of language in identifying and triggering emotions and appraisals.

The paper connects two central ethical views, both with a rich tradition, sentimentalism and contractualism. From the former, it also borrows the response-dependentist metaphysics. The idea of combining the two has been sketched before, but not systematically and explicitly; for instance, in various comments on classical authors, especially on Kant and elsewhere, most prominently in Habermas. Here is the kernel of the present proposal. Our initial practical intuitions are emotion-based and the values, when detected, are response-dependent. This is the starting (...) point borrowed from sentimentalism. These intuitions get improved by reflection, and by dialogue that crucially involves perspective taking. If all goes well, this results in insights, in particular into principles that all rational parties can agree about in a kind of “contract.” This brings two traditions, the one of David Hume and Adam Smith, and the other of Kant, together. The resulting theory would be a kind of sentimentalist, response-dependentist contractualism. (shrink)

In understanding the degree of choice we have in our emotions, we benefit from the Stoics’ analysis into first and second movements: appraisals and reappraisals. The Stoics were concerned to avoid the harm that emotions can cause, but their idea of working on goals, rather than on emotions as such, generalizes beyond their concerns. For modern people, the problem of taking responsibility for our emotional life becomes less paradoxical when we consider interpersonal issues.

In this paper I argue that semiotic cognition is a distinctive form of cognition, which must have evolved out of earlier forms of non-semiotic cognition. Semiotic cognition depends on the use of signs. Signs are understood in terms of a specific organization, or structure, of the cognitive process. Semiotic cognition is a unique form of cognition. Once this form of cognition was available to humans, the semiotic provided the ground structure for an evolutionary development that was no longer strictly Darwinian, (...) but followed its own — semiotic — logic. In the increasingly abstract ways in which the ubiquitous difference is dealt with, we discover this logic of cultural evolution, which determines the course of long term cultural change. (shrink)
