Clearly self 1 is the self of self-identity, whereas self 2 recognises the changing human being over time and self 3 is the social identity. Self 1 is, I think, the self which Mead described as emerging within the mind. Self 2 emerges over time as we develop and become self-aware, whereas self 3 is experienced from babyhood and as such may help determine the other two elements. This is akin to 'Me'. The person is, for him, a combination of all three senses of self and these can be seen through the distinctness, continuity and autonomy of the person, following Apter (1989: 75). This unified self is a product of social processes. Harre (1998: 3) writes:
... the self as the singularity we each feel ourselves to be, is not an entity. Rather it is a site, a site from which a person perceives the world and a place from which to act.
