I did my first online interview yesterday in connection with my book. I found it an odd and interesting experience because I was asked not so much about contemporary art museums and how they display art, which is the subject of my book, but about history museums, including the National Portrait Gallery, and how they represent the past, based round the increasingly common view that we can in some way punish people retrospectively for the views that they held, many of which were, in the light of current attitudes, clearly unacceptable and sometimes abhorrent. It’s an issue which is caught up in the current culture wars which are polarised in a way which is incredibly unhelpful. It will be interesting to see what stance the new Mayor’s diversity commission takes and I was pleased to see that it was not about taking statues down, but putting them up, which seems to me to be the right approach, diversifying attitudes to commemoration, rather than trying to abolish attitudes to commemoration in the past.
