Damien Hirst's Mother and Child Divided (1993) is a work which can at first glance be read as nothing more than two brutally severed carcasses. "A freak show" was how the art critic of the Sunday Telegraph responded to its presentation in the Turner Prize in 1995. For me, the undoubted shock, even disgust provoked by the work is part of its appeal. Art should be transgressive. Life is not all sweet.
