Abstract: | This paper reviews the evidence that social disaggregation is a major cause of destructive violence in non-human animal societies. The multifactorial theory of agonistic behavior is modified into a polysystemic theory which relates factors on each level to each other in an integrated model. As a result, it is suggested that disaggregation of systems on any level may lead to maladaptive violence. On theoretical grounds it is concluded that disaggregations of ecosystems and social systems are more probable and hence more dangerous than those of physiological and genetic systems. Applications of these findings to human affairs are discussed, both as explanations and as guides to positive action. |
