I have proposed a theory of "self" that is comprised of four components: personal identity, personal (self) esteem, collective identity, and collective esteem. The theory proposes first that cultural identity is a person's most important collective identity, and second that a clear collective identity is the necessary psychological basis upon which personal identity and esteem are built. The theory is being applied to the challenges confronting Aboriginal people, street kids, refugees, and visible minority groups.
