Even as paleoanthropology becomes increasingly sophisticated in revealing both the broad contours and the details of the deep evolutionary history of Homo sapiens, it continues to be informed by lingering pre-evolutionary residues. Specifically, the goal of prior research was to demonstrate that the influence of the ancient Scala Naturae as an organizing principle significantly contributed to the scientific community’s delayed acceptance of Australopithecus as a plesiomorphic member of the Hominidae. The present study extends this research through a selective examination of (...) non-primary source material reporting on significant early hominid discoveries over the last century, beginning with Australopithecus africanus and ending with Ardipithecus ramidus. It is argued that these accessible sources reify to varying degrees the perception among the non-expert public that human beings are an inevitable culmination of the evolutionary process. This culturally transmitted schema of human exceptionalism continues to impact other life on Earth in profound ways, in some cases with calamitous results. (shrink)

This essay begins by remarking that the broad understanding of atheism is not a position that theism per se commits one to claiming is unreasonable. The essay then, however, proceeds to present an argument against atheism being reasonable. This constitutes a variant of the fine-tuning version of the Design Argument, and contends that both the universe’s fine-tuning to us, and our fine-tuning to the universe, are better explained by the ‘God hypothesis’ than by a range of alternatives. While admitting that (...) there is no single ‘killer argument’ against atheism, the essay argues that a persuasive, cumulative case for the God hypothesis—with cosmic fine-tuning as its strongest suit—can nevertheless be constructed.

In this article, I consider what states of knowledge of the value of outcomes are consistent with a classical theist's praying to God that He bring about those outcomes. I proceed from a consideration of the cases which seem least problematic (the theist knows these outcomes to be ones which would be, at least after they've been prayed for, best or at least good), through a consideration of cases where the outcomes prayed for are ones the goodness and badness of (...) which the theist is agnostic about, to consider finally praying for outcomes that the theist knows would be bad at the time he or she is praying for them. I conclude that even prayers of this last sort should, albeit only on rare occasions, be prayed. (shrink)

Reinforcement learning systems usually assume that a value function is defined over all states that can immediately give the value of a particular state or action. These values are used by a selection mechanism to decide which action to take. In contrast, when humans and animals make decisions, they collect evidence for different alternatives over time and take action only when sufficient evidence has been accumulated. We have previously developed a model of memory processing that includes semantic, episodic and working (...) memory in a comprehensive architecture. Here, we describe how this memory mechanism can support decision making when the alternatives cannot be evaluated based on immediate sensory information alone. Instead we first imagine, and then evaluate a possible future that will result from choosing one of the alternatives. Here we present an extended model that can be used as a model for decision making that depends on accumulating evidence over time, whether that information comes from the sequential attention to different sensory properties or from internal simulation of the consequences of making a particular choice. We show how the new model explains both simple immediate choices, choices that depend on multiple sensory factors and complicated selections between alternatives that require forward looking simulations based on episodic and semantic memory structures. In this framework, vicarious trial and error is explained as an internal simulation that accumulates evidence for a particular choice. We argue that a system like this forms the “missing link” between more traditional ideas of semantic and episodic memory, and the associative nature of reinforcement learning. (shrink)

This paper argues that intelligence can be approximated by the ability to produce accurate predictions. It is further argued that general intelligence can be approximated by context dependent predictive abilities combined with the ability to use working memory to abstract away contextual information. The flexibility associated with general intelligence can be understood as the ability to use selective attention to focus on specific aspects of sensory impressions to identify patterns, which can then be used to predict events in novel situations (...) and environments. The argumentation synthesizes Godfrey-Smith’s environmental complexity theory, adding the notion of niche broadness as well as changes concerning the view of cognition and control, and Hohwy’s predictive mind theory, making explicit the significance of accuracy as a composite of trueness and precision where the nervous system acts as a distributed controller motivating actions that keep the body in homeostasis.

This article explores the issue of girls’ concerns about sexual activity in a liberal Nordic context. Drawing on ethnographic fieldwork among young people in Denmark, the article identifies three types of concerns girls can have about sexual activity: social expectations, relational expectations and dignity. Whilst contemporary research has tended to focus on the influence different sexual morality discourses have in shaping different expectations and concerns about these, little attention seems to be paid to girls’ normative concerns about sex related to (...) well-being. This article sheds light on how these normative concerns are related to girls’ sense of dignity based on Andrew Sayer’s work on dignity and moral sentiments. Finally, the article argues that tension between sexual morality discourses and moral sentiments may be the source of resistance that girls practise with a new ‘fuckboy’ discourse. (shrink)
