Evolutionary debunking arguments and the reliability of moral cognition.Benjamin James Fraser -2014 -Philosophical Studies 168 (2):457-473.detailsRecent debate in metaethics over evolutionary debunking arguments against morality has shown a tendency to abstract away from relevant empirical detail. Here, I engage the debate about Darwinian debunking of morality with relevant empirical issues. I present four conditions that must be met in order for it to be reasonable to expect an evolved cognitive faculty to be reliable: the environment, information, error, and tracking conditions. I then argue that these conditions are not met in the case of our evolved (...) faculty for moral judgement. (shrink)
Adaptation, Exaptation, By-Products, and Spandrels in Evolutionary Explanations of Morality.Benjamin James Fraser -2010 -Biological Theory 5 (3):223-227.detailsAdaptationist accounts of morality attempt to explain the evolution of morality in terms of the selective advantage that judging in moral terms secured for our ancestors (e.g. Ruse 1998; Joyce 2006; Street 2006). So-called by-product explanations of morality have been presented as an alternative to adaptationist accounts (e.g. Prinz 2009; Ayala 2010; cf. Darwin 2004/1871). In assessing the relationship between adaptationist and by-product accounts, care must be taken to distinguish several related but importantly different notions: innateness, adaptation, exaptation, spandrel, and (...) by-product.
