agonic

By cultivating his own reason, the pupil could stand back from the agonic scenes in Hades and decide the merits of the case after [François] Fénelon's artifice had absorbed him passionately in the dialogue: […]

[I]n some primates, especially chimpanzees, the hedonic mode of social communication predominates group interactions. […] This is marked by much physical contact, stroking, hugging, lip smacking and sharing. The social interactions are more relaxed, as are the individual members of the group, and there is much focus on physical contact. This is in marked contrast to other more primitive primates, where the agonic mode dominates social behaviour.

A study of the conditions under which agonic invagination of the intestine occurs will not be out of place in considering the etiology of intussusception. Agonic invagination is very much more common in children than adults, the proportion being, according to [Hermann] Nothnagel, one to fifty. [Luther Emmett] Holt says that agonic invagination is met with in 80 per cent. of the post mortems on infants.
