Behavioral Evolution and Integrative Levels

First published in 1984. In this collection of essays Schneirla is identified as a scientist and citizen unafraid to hold and present unpopular ideas. Schneirla had always been opposed to the hereditarian views that allowed for the politicalization of psychology and spoke out early against the idea of the genetic basis of behavior. It is fitting that his ideas which still form the nexus of the major theoretical criticism of classical ethology now can be seen to stand in opposition to the hereditarian views of socio-biology.
