Mercier & Sperber (M&S) claim that the phenomenon of belief bias provides fundamental support for their argumentative theory and its basis in intuitive judgement. We propose that chronometric evidence necessitates a more nuanced account of belief bias that is not readily captured by argumentative theory.

Short abstract (98 words). Reasoning is generally seen as a means to improve knowledge and make better decisions. However, much evidence shows that reasoning often leads to epistemic distortions and poor decisions. This suggests that the function of reasoning should be rethought. Our hypothesis is that the function of reasoning is argumentative. It is to devise and evaluate arguments intended to persuade. Reasoning so conceived is adaptive given humans’ exceptional dependence on communication and vulnerability to misinformation. A wide range of (...) evidence in the psychology of reasoning and decision making can be reinterpreted and better explained in the light of this hypothesis. (shrink)

Expert reasoning is responsible for some of the most stunning human achievements, but also for some of the most disastrous decisions ever made. The argumentative theory of reasoning has proven very effective at explaining the pattern of reasoning’s successes and failures. In the present article, it is expanded to account for expert reasoning. The argumentative theory predicts that reasoning should display a strong confirmation bias. If argument quality is not sufficiently high in a domain, the confirmation bias will make experts (...) tap into their vast knowledge to defend whatever opinion they hold, with polarization and overconfidence as expected results. By contrast, experts should benefit even more from the power of group discussion to make the best of the confirmation bias—when they genuinely disagree that is, otherwise polarization is again likely to ensue. When experts interact with laymen other mechanisms can take the lead, in particular trust calibration and consistency checking. They can yield poor outcomes if experts do not have a sustained interaction with laymen, or if the laymen have strong opinions when they witness a debate between experts. Seeing reasoning as a mechanism of epistemic vigilance aimed at finding and evaluating arguments helps make better sense of expert reasoning performance, be it in individual ratiocination, in debates with other experts, or in interactions with laymen.

This article considers the imago Dei from the perspective of paleoanthropology. We identify structural, functional, and relational elements of the imago Dei that emerged mosaically during human evolution. Humans are unique in their ability to relate to each other and to God, and in their membership of cultural communities where shared attention, the transmission of moral norms, and symbolic behavior are important elements. We discuss similarities between our approach and the concept of theosis adopted in the Eastern Orthodox Church.

Controlled fire use by early humans could have facilitated the evolution of human cooperation. Individuals with regular access to the benefits of domestic fire would have been at an advantage over those with limited or no access. However, a campfire would have been relatively costly for an individual to maintain and open to free riders. By cooperating, individuals could have reduced maintenance costs, minimized free riding and lessened the risk of being without fire. Cooperators were more likely to survive and (...) reproduce than uncooperative individuals because the former would have been better able to maximize a fire’s returns and enjoy regular access to its benefits. This is how the emergence of controlled fire use in Pleistocene human populations could have facilitated the evolution of cooperation. (shrink)

Dubreuil (Biol Phil 25:53–73, 2010b , this journal) argues that modern-like cognitive abilities for inhibitory control and goal maintenance most likely evolved in Homo heidelbergensis , much before the evolution of oft-cited modern traits, such as symbolism and art. Dubreuil’s argument proceeds in two steps. First, he identifies two behavioral traits that are supposed to be indicative of the presence of a capacity for inhibition and goal maintenance: cooperative feeding and cooperative breeding. Next, he tries to show that these behavioral (...) traits most likely emerged in Homo heidelbergensis . In this paper, I show that neither of these steps are warranted in light of current scientific evidence, and thus, that the evolutionary background of human executive functions, such as inhibition and goal maintenance, remains obscure. Nonetheless, I suggest that cooperative breeding might mark a crucial step in the evolution of our species: its early emergence in Homo erectus might have favored a social intelligence that was required to get modernity really off the ground in Homo sapiens.

V nasledujúcom príspevku sa snažíme zdôvodniť vyčlenenie troch typov procesov v pozorovanom vesmíre - procesov slabo, stredne a silne usmernených, a to na základe rôznej miery autonómnosti ich štruktúrnych prvkov a rôznej miery či intenzity zákonov, ktorými sú usmerňované alebo riadené. Individuálne a konkrétne procesy sú tak v podstate totožné s individuálnymi a konkrétnymi systémami, cez ktoré, v ktorých a prostredníctvom ktorých sa úplne realizujú, disponujúc tak vždy a všade vlastným substanciálnym obsahom. Na tomto základe potom vyčleňujeme slabo usmernené procesy (...) v neživej prírode s málo vyčlenenými alebo autonómnymi štruktúrnymi prvkami, stredne usmernené procesy živej prírody s oveľa väčšími, vyčlenenejšími a autonómnejšími štruktúrnymi prvkami vo forme živých buniek a postupne rastúcich a zdokonaľujúcich sa organizmov a tried organizmov a nakoniec silne usmernené procesy tzv. sociálnej prírody alebo ľudskej spoločnosti, pozostávajúcej z ľudí ako svojich základných alebo štruktúrnych prvkov a tiež z nimi generovaného technického a/lebo civilizačného "obalu", ktoré sú podobne ako živé procesy a systémy usmerňované a riadené čoraz väčším počtom pre nich špecifických vedeckých zákonov, princípov alebo "pravidiel".

Mercier & Sperber (M&S) argue for their argumentative theory in terms of communicative abilities. Insights can be gained by extending the discussion beyond human reasoning to rodent and robot navigation. The selection of arguments and conclusions that are mutually reinforcing can be cast as a form of abductive reasoning that I argue underlies the construction of cognitive maps in navigation tasks.

There has been much debate regarding when modern human cognition arose. It was previously thought that the technocomplexes and artifacts associated with a particular timeframe during the Upper Paleolithic could provide a proxy for identifying the signature of modern cognition. It now appears that this approach has underestimated the complexity of human behavior on a number of different levels. As the artifacts, once thought to be confined to Europe 40,000 years ago onwards, can now be found in other parts of (...) the world well before this date, especially in South Africa, this suggests that modern cognition arose well before this period. Moreover, the variability of the archaeological record from the time when anatomically modern humans appeared 200,000 years ago suggests cognitive factors alone are unable to explain the obvious unevenness. In this article, it will be demonstrated how neuro-cognition can be assimilated with population dynamics and the transmission of information between individuals and groups that can provide important insights as to the nature and origins of modern human cognition.
