Recently, I visited Ai Weiwei’s exhibition at the Royal Academy of Arts in London. The galleries were full, with visitors of all ages and many nationalities engaging with the profound and thought-provoking displays. It was heartening to find the RA confronting the issues raised by Ai Weiwei through his work in a measured, sensitive and deeply thoughtful way. Visitors are encouraged to take photographs and share them through social media. Ai Weiwei’s work speaks for itself and testifies to the power of art to make us think about other people’s lives, the problems they face when they do not live in a democratic society where freedom of expression is taken for granted, and what we can do to help bring about change for the better.
