Over the last several decades Ellen Dissanayake has developed an evolutionary theory of art that views all art as having evolved for the function of promoting group cohesion. This theory is not without its critics, yet it has received little empirical attention. In this article I propose a more modest formulation of Dissanayake’s hypothesis and proceed to test it using a cross-cultural analysis. I rely on the ethnographic databases of the electronic Human Relations Area Files as well as the Standard (...) Cross-Cultural Sample to compare proxies for group cohesion with measures of ritual art, a subset of art that I theoretically define. While my results cannot decisively prove or disprove Dissanayake’s hypothesis, they do lend empirical support to her views. This is promising not only for her views but for outlining ways of empirically testing other views in evolutionary aesthetics. (shrink)

Although the theory of memetics appeared highly promising at the beginning, it is no longer considered a scientific theory among contemporary evolutionary scholars. This study aims to compare the genealogy of memetics with the historically more successful gene-culture coevolution theory. This comparison is made in order to determine the constraints that emerged during the internal development of the memetics theory that could bias memeticists to work on the ontology of meme units as opposed to hypotheses testing, which was adopted by (...) the gene-culture scholars. I trace this problem back to the diachronic development of memetics to its origin in the gene-centered anti-group-selectionist argument of George C. Williams and Richard Dawkins. The strict adoption of this argument predisposed memeticists with the a priori idea that there is no evolution without discrete units of selection, which in turn, made them dependent on the principal separation of biological and memetic fitness. This separation thus prevented memeticists from accepting an adaptationist view of culture which, on the contrary, allowed gene-culture theorists to attract more scientists to test the hypotheses, creating the historical success of the gene-culture coevolution theory.

Abstract:Liberal thinkers of the Enlightenment understood that surplus moral constraints, imposed by invalid moral norms, are a serious limitation on liberty. They also recognized that overcoming surplus moral constraints — what we call proper de-moralization — is an important dimension of moral progress. Contemporary philosophical theorists of liberty have largely neglected the threat that surplus moral constraints pose to liberty and the importance of proper de-moralization for human emancipation. This essay examines the phenomena of surplus moral constraints and proper de-moralization, (...) utilizing insights from biological and cultural evolutionary thinking. (shrink)

This is an updated version of my Stanford Encyclopedia entry on Evolutionary Psychology. The 2018 version contains a new section on Human Nature as well as some new material on recent developments in Evolutionary Psychology.
