I added a link to Jung’s concept of “persona” to the sidebar of this community: For Jung, “the danger is that [people] become identical with their personas—the professor with his textbook, the tenor with his voice.” The result could be “the shallow, brittle, conformist kind of personality which is ‘all persona’, with its excessive concern for ‘what people think’”—an unreflecting state of mind “in which people are utterly unconscious of any distinction between themselves and the world in which they live. They have little or no concept of themselves as beings distinct from what society expects of them.”
