Try to summarise this passage in one or two sentences:
Identity is about belonging, about what you have in common with some people and what differentiates you from others. At its most basic it gives you a sense of personal location, the stable core to your individuality. But it is also about your social relationships, your complex involvement with others, and in the modern world these have become ever more complex and confusing. Each of us live with a variety of potentially contradictory identities, which battle within us for allegiance: as men or women, black or white, straight or gay, able-bodied or disabled, ‘British’ or ‘European’ … The list is potentially infinite, and so therefore are our possible belongings. Which of them we focus on, bring to the fore, ‘identify’ with, depends on a host of factors. At the centre, however, are the values we share or wish to share with others (Weeks 1990, 88).
