The species problem is often described as the abundance of conflicting definitions of _species_, such as the biological species concept and phylogenetic species concepts. But biologists understand the notion of species in a non-definitional as well as a definitional way. In this article I argue that when they understand _species_ without a definition in their mind, their understanding is often mediated by the notion of _good species_, or prototypical species, as the idea of ``prototype'' is explicated in cognitive psychology. This (...) distinction helps us make sense of several puzzling phenomena regarding biologists' dealing with species, such as the fact that in everyday research biologists often behave as if the species problem is solved, while they should be fully aware that it is not. I also briefly discuss implications of this finding, including that some extant attempts to answer what the nature of species is have an inadequate assumption about how the notion of species is represented in biologists' minds.

Recently several prominent biologists and philosophers, including Feinberg and Mallatt, and Godfrey-Smith, have proposed evolutionary accounts of consciousness. Despite disagreements regarding the specifics, they all focused on the “primitive” form of consciousness and argued that its origin is much more ancient than previously believed. In this study, we examine these accounts based on their methodological grounds. Specifically, we examine whether one methodological criticism leveled against evolutionary psychology on the completeness of its explanations can be applied to Feinberg and Mallatt’s adaptation (...) explanations. We conclude that their explanations fall short of being complete, but fare better than those advanced by evolutionary psychologists. (shrink)

Advocates of moral enhancement through pharmacological, genetic, or other direct interventions sometimes explicitly argue, or assume without argument, that traditional moral education and development is insufficient to bring about moral enhancement. Traditional moral education grounded in a Kohlbergian theory of moral development is indeed unsuitable for that task; however, the psychology of moral development and education has come a long way since then. Recent studies support the view that moral cognition is a higher-order process, unified at a functional level, and (...) that a specific moral faculty does not exist. It is more likely that moral cognition involves a number of different mechanisms, each connected to other cognitive and affective processes. Taking this evidence into account, we propose a novel, empirically informed approach to moral development and education, in children and adults, which is based on a cognitive-affective approach to moral dispositions. This is an interpretative approach that derives from the cognitive-affective personality system (Mischel and Shoda, 1995). This conception individuates moral dispositions by reference to the cognitive and affective processes that realise them. Conceived of in this way, moral dispositions influence an agent's behaviour when they interact with situational factors, such as mood or social context. Understanding moral dispositions in this way lays the groundwork for proposing a range of indirect methods of moral enhancement, techniques that promise similar results as direct interventions whilst posing fewer risks.

V rámci filosofie věd panuje široká shoda na tom, že druhá polovina 20. století složila „labutí píseň" pozitivismu. Milton Friedman a Paul Samuelson, dva klíčoví autoři k metodologii ekonomie v daném časovém období, přitom tento vývoj ve filosofii vědy prý nikdy nereflektovali. Pozitivistická východiska - v prvé řadě v podobě redukcioni- stického přístupu - jsou tudíž stále přítomna ve vlivných teoretických konceptech rozvinutých ekonomy hlavního proudu. Značný počet autorů však v současnosti sdílí náhled, že tyto koncepty v nezanedbatelné míře (...) přispěly k vývoji, jenž ústil ve finanční krizi, vrcholící v letech 2008 a 2009. Předkládaný článek se proto táže, zda to byla právě krize - v níž mnozí spatřují empirické zamítnutí řady pozitivistických konceptů - která napsala „labutí píseň" pozitivismu v ekonomii hlavního proudu.
