Abstract: | The concept of identity is ubiquitous in public discourse even though its meaning is often imprecise or nebulous – it is maybe because of this that its contents can be taken for granted. One speaks of individual, personal, group, social, collective and political identity; of identity formation, crisis, diffusion, conflict and politics; a multiple identity may be pathological or a component of an integrated identity; culture and ideology but also knowledge and experience supposedly enrich identity; identity may be rigid or open to development and growth – and so on. Against this background the present paper explores the argumentative uses of the concept of identity in psychoanalysis and in social psychology and sociology. |
