The real difficulty about volcanism is not to see how it can start, but how it can stop.
I re-read The History of White People by Nell Irvin Painter. It's a book every one should read, particularly Americans, as the USA is her primary focus. Her book demonstrates that white is not universal, that white is not neutral, that it has a history, which she eloquently delineates. It's not often you finish a book understanding how the world operates better than before you read it.
