Abstract

Here I briefly discuss some comparative data on social play behaviour in hope of broadening the array of species in which researchers attempt to study animal morality. I am specifically concerned with the notion of ‘behaving fairly'. In the term ‘behaving fairly’ I use as a working guide the notion that animals often have social expectations when they engage in various sorts of social encounters the violation of which constitutes being treated unfairly because of a lapse in social etiquette. I will cash this out below in my discussion of social play behaviour
