homo natura

HOMO NATURA; to bring it about that man shall henceforth stand before man as he now, hardened by the discipline of science, stands before the OTHER forms of nature, with fearless Oedipus-eyes, and stopped Ulysses-ears, deaf to the enticements of old metaphysical bird-catchers, who have piped to him far too long: “Thou art more! thou art higher! thou hast a different origin!” — FN, beyond good and evil, 7, 233.

Religious, ethnic, and racial favoritism is natural, scientists say.

From: Bates and Lewis, 2010. Genetic Evidence for Multiple Biological Mechanisms Underlying In-Group Favoritism:

Abstract: In-group favoritism is ubiquitous and associated with intergroup conflict, yet is little understood from a biological perspective. A fundamental question regarding the structure of favoritism is whether it is inflexibly directed toward distinct, “essentialist” categories, such as ethnicity and race, or is deployed in a context-sensitive manner. In this article, we report the first study (to our knowledge) of the genetic and environmental structure of in-group favoritism in the religious, ethnic, and racial domains. We contrasted a model of favoritism based on a single domain-general central affiliation mechanism (CAM) with a model in which each domain was influencedby specific mechanisms. In a series of multivariate analyses, utilizing a large, representative sample of twins, models containing only the CAM or essentialist domains fit the data poorly. The best-fitting model revealed that a biological mechanism facilitates affiliation with arbitrary groups and exists alongside essentialist systems that evolved to process salient cues, such as shared beliefs and ancestry.
