ABSTRACT
The present author has long argued that the concept of joint commitment at issue in this article is central to human life in society. More precisely I have argued that central everyday concepts of at least the following phenomena incorporate this concept: agreements, promises, social groups, group languages, social rules and conventions, doing something with another person, shared or collective plans, collective belief and other collective attitudes, collective emotions, and an important kind of mutual recognition (Gilbert 1989, 2006, 2014 and elsewhere).
