It is very hard to answer the oft-posed questions about how Abraham Lincoln would respond to some current condition. My favorite story on that count is that the late great Lincoln scholar Don Fehrebacher was asked, during the struggles over bussing for racial balance a few years ago, what Lincoln would say about "bussing" and he thought awhile and then answered : "what Lincoln would say would be: "What's a bus?"

The situation Abraham Lincoln faced was unique. In his view, the United States was threatened with destruction, ruin, overthrow, perishing - all words that he used - which is not the case for any other president, including the current one - Barack Obama.

There was specific constitutional provision for emergency measures in the case that Abraham Lincoln faced - an insurrection - which no other president has faced.

After I published a book called Lincoln's Virtues a wit said that my next book should be Lincoln's Vices. But in my opinion that would be a short book!

I do not think you can fault Abraham Lincoln for picking generals that did not work out, because, as he said to John Hay when he went back to George B. McClellan in the fall of 62, we have to work with what we have.

Abraham Lincoln was not philosopher, exactly. But he did have a strong mind, which sought generalizations as well as particulars. He had a terrific memory.

Yes, the rise in corporate power had roots in the gearing up for the Civil War. Abraham Lincoln was a Whig, a supporter of government aid to expanding industry - to "internal improvements" that supported the growth of business. He was an early capitalist, not one who wanted to preserve some rural paradise.
