Life Goals, Evolution and
Mood
Most human goals are social;
emotions
are our means of steering.

Précis
Emotions are processes that manage goals. We are a social species, so human goals are for the most part social. We achieve together many outcomes that we could not possibly accomplish alone. Oatley and Jenkins have recently developed a theory of three major social-goal systems that have evolved in mammals. One system is assertion or dominance. Its goal is to move up in a status hierarchy and to maintain one's position if challenged. Its characteristic emotion is anger. The second system is attachment. Its goal is protection from inter-species predation and intra-species aggression. Its characteristic emotion is anxiety. The third, and most recently evolved is affection. Its goal is interpersonal warmth, and its characteristic emotions are happiness and love. Among humans, most (though not all) emotions relate to these systems. I shall describe how these emotions arise and describe, also, exceptions to this scheme. These systems affect fitness by specific moods setting up scripts for specific kinds of relationships with others. Anger sets up relationships of conflict, anxiety sets up relationships of protectiveness, happiness sets up relationships of cooperation. People navigate the social world largely by way of these emotions, which act as guides to social action. Two different kind of depression are based on (i) loss of status and (ii) loss of a partner in attachment or cooperation. Depression exemplifies the problematics of guidance by social goals. Among modern humans none of the three systems, none of the interactions among them, and none of the repertoires of emotions that each calls into readiness, is without paradoxes. Narrative stories are human universals: they are means of simulating problematic situations in order to gain
insights into their personal and social properties.
