Art is memory. It is the excavation of so many memories we have had — of our mothers, our best and worst moments, of glorious experiences we have had with friends or films or music or dance or a lovely afternoon on a sloping, green hill. All of this enters us and, if we are artists, must be shared, handed over to others. This is why it is so important to know what came before you. It is also important to understand that things will follow you, and they may come along and make your work look pedestrian and silly. This is fine; this is progress. We have to work with what life presents to us, and we have to work as well as we can while we can.
