Work is hard. Distractions are plentiful. And time is short.

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."

Even [Ernst] Hemingway, perhaps the most intentionally non-political of American writers, became passionately partisan during the Spanish Civil War.

How many really great writers are there who are totally non-political? You can hear the French Revolution in the poetry of [Percy Bysshe] Shelly and [John] Wordsworth; you can sense the vast inequalities of Tsarist Russia in [Anton] Chekhov and [Lev] Tolstoy.

I think one thing writers can do is point out that you don't have to say openly racist things, like [Donald] Trump, to be a racist or a xenophobe.

Someday, I have no doubt, the dead from today's wars will be seen with a similar sense of sorrow at needless loss and folly as those millions of men who lie in the cemeteries of France and Belgium - and tens of millions of Americans will feel a similar revulsion for the politicians and generals who were so spendthrift with others' lives.

Newt Gingrich seldom misses a chance to note that he is a historian.
