We do not want to destroy unnecessarily what men spent so much time and care and skill in making… [for] these examples of craftsmanship tell us so much about our ancestors.… If these things are lost or broken or destroyed, we lose a valuable part of our knowledge about our forefathers. No age lives entirely alone; every civilisation is formed not merely by its own achievements but by what it has inherited from the past. If these things are destroyed, we have lost a part of our past, and we shall be the poorer for it. —British Monuments Man Ronald Balfour, draft lecture for soldiers, 1944
