Marc Quinn’s statue of the disabled artist Alison Lapper naked and eight months pregnant, was installed in Trafalgar Square in September 2005. It exemplifies what’s wrong in modern Britain, writes Brendan O’Neill. “It shows that we value people for what they are rather than what they achieve. In our era of the politics of identity we seem more interested in celebrating individuals’ fixed and quite accidental attributes – their ethnicity, cultural heritage or in Lapper’s case, her disability – rather than what they have discovered or done in the world outside of their bodies. We prefer victims to heroes.”
