The late Nadine Gordimer in South Africa, for example, had a wonderful ability to get her country's injustices and contradictions down on paper. Ditto for her countryman the great playwright Athol Fugard.

Some 2,800 Americans went to Spain [during the Spanish Civil War], and it was, by far, the largest number of Americans before or since who've ever joined somebody else's civil war. I think they were primarily people who were deeply alarmed by the menace of fascism. They saw this on the horizon. I quote one volunteer, Maury Colow of New York, who said, "for us it was never Franco, it was always Hitler."

I'm after a snake and please God I'll scotch it.

I think [George] Orwell is right. There are certainly moments when political differences appear minor, and someone can claim to be non-political or to want to stay out of the fray, but today is not one of those moments.

And yet the world we live in-its divisions and conflicts, its widening gap between rich and poor, its seemingly inexplicable outbursts of violence-is shaped far less by what we celebrate and mythologize than by the painful events we try to forget. Leopold's Congo is but one of those silences of history.

Speaking of Germany in 1933, I don't think you can remove yourself from politics when, in so many countries - the United States, Poland, Hungary, and many others - you've got politicians in power or vying for power who are taking tactics and elements of their appeal from the playbook of fascism.

It sure is a rising tide, and we have a particularly nasty exemplar of it in the U.S., in Donald Trump.
