Interdisciplinarity is widely promulgated as beneficial to science and society. However, there are three quite serious problems which can limit the success of any interdisciplinary research collaboration. The first problem is expertise (it takes years of effort to cultivate a deep knowledge of even one discipline). The second problem is comprehensibility (experts in different disciplines do not reliably understand each other). The third problem is service (in a given interdisciplinary endeavour, it often occurs that one discipline benefits and the other (...) discipline does not benefit). This essay is an elaboration of these three problems. Parallels are drawn between translation between languages and translation between disciplines. (shrink)

The original book chapter does not have an abstract. However, I have written an abstract for this repository: Religious life encompasses a wide diversity of situations for which the emotional tone is on a continuum from extreme euphoria to extreme dysphoria. In this book chapter, we propose the novel hypothesis that euphoria and dysphoria have distinctly separate functional consequences for religious evolution and survivability. This is due to the differential cognitive states that are created in euphoric and dysphoric situations. Based (...) on readings from religious studies and cognitive psychology, we propose that euphoria in religion is conducive to social bonding and situations needing lateral thinking and creativity; whereas dysphoria in religion is conducive to situations where precision and analogical reasoning are necessary.

In his classic Film as Art, Rudolf Arnheim sets out to refute the claim that “Film cannot be art, for it does nothing but reproduce reality mechanically”.1 The usual argument in favor of that claim, he explains, contrasts film with realist painting, and goes something like this: There’s no doubt that what appears on the canvas depends on the way the painter sees the world, on her particular technique, on the colors she’s using, and so on. It is elements like (...) these that justify aesthetic appreciation. What appears on celluloid, on the other hand, is the result of a purely mechanical process of light rays collecting and transforming into an image. In other words, a camera is merely a mechanical recording device, and for this very reason film cannot be art. (shrink)

Direct reciprocity, indirect reciprocity, and reputation are important interrelated topics in the evolution of sociality. This non-mathematical review is a summary of each. Direct reciprocity (the positive kind) has a straightforward structure (e.g., "A rewards B, then rewards A") but the allocation might differ from the process that enabled it (e.g., whether it is true reciprocity or some form of mutualism). Indirect reciprocity (the positive kind) occurs when person (B) is rewarded by a third party (A) after doing a good (...) deed towards somebody else (C) — with the structure "A observes B help C, therefore A helps B." Here too, the allocation differs from the process: if there is underlying cognition, then indirect reciprocity is based on some ability to keep track of the reputations of others (to remember that "B helped C"). Reputation is a kind of social impression based on typicality, derived from three channels of experience (direct encounters, bystander observation, and gossip). Although non-human animals cannot gossip verbally, they can eavesdrop on third parties and learn vicariously. This paper ends with a proposal to investigate the topic of social expertise as a model for understanding how animals understand and utilise observed information within their social groups. (shrink)

The complexity that we observe in nature can often be explained in terms of cooperative behavior. For example, the major transitions of evolution required the emergence of cooperation among the lower-level units of selection, which led to specialization through division-of-labor ultimately resulting in spontaneous order. There are two aspects to address explaining how such cooperation is sustained: how free-riders are prevented from free-riding on the benefits of cooperative tasks, and just as importantly, how those social benefits arise. We review these (...) problems from an economic perspective, and highlight how ideas from economics can help us to better understand how the benefits of social interactions arise, how they are sustained, and how they affect the underlying social dilemmas.

Les récits de fiction comportant une moralité déviante posent parfois problème quant à la détermination de ce qui est « vrai dans l’histoire ». Si par exemple on a aucune difficulté à considérer comme vrai dans le monde imaginaire que « Giselda a tué son bébé », les choses sont différentes lorsqu’il s’agit d’imaginer une situation dans laquelle nos valeurs morales sont remises en question. Confronté à un récit comportant l’énoncé « Giselda a fait la bonne chose en tuant son (...) bébé, après tout, c’était une fille », on aura tendance à questionner l’autorité de l’auteur : celui-ci peut bien penser que l’infanticide féminin est moralement justifié, mais en fait c’est faux, même dans l’histoire. Les conditions qui donnent lieu au phénomène ont été articulées de diverses façons, l’objectif étant habituellement de parvenir à une formulation qui dépasse le cadre plus étroitement moral. On invoque par exemple une distinction plus générale entre l’évaluatif et le descriptif. Après avoir caractérisé plus précisément les notions d’imagination et d’imaginabilité, j’exami- nerai brièvement la littérature sur le sujet et défendrai une solution reposant sur les règles de modification de l’extension et de l’intension des prédicats imaginaires. D’après cette analyse, ce qui se produit dans les récits moraux déviants s’explique par un principe plus général qui s’applique autant à l’évaluatif qu’au descriptif. (shrink)
