The intentional and meaningful activity of a person. Habermas, following the sociologist Max Weber, distinguishes `action' from `behaviour' (Habermas 2001c: 4±6). Behaviour is the involuntary or causally determined activity of the person, such as a re¯ex response to an external stimulus (for example, ¯inching) or the on-going processes of the body (for example, heartbeat), as opposed to the activities that the person intends to perform, and that will have some meaning for them and the people around them.
