It's the late show, poncho with Stephen Colbert.

Ladies and gentlemen, my next guest is the New York Times bestselling author, known for his biographies of figures like Leonardo da Vinci, Steve Jobs, and Einstein.

His new book is The Greatest Sentence Ever Written.

Please welcome back to The Late Show, Walter Isaacson.

All right, the latest book right here.

The greatest sentence ever written.

Hey.

Is it the greatest book you've ever written?

It's the shortest by far.

It's a short, exactly.

I was like it must be pretty pithy.

It's only 67 pages.

But, you know, that's the exact same length as Thomas Payne, who wrote the pamphlet that 250 years ago started the revolution. I figured if he could do it in that length, I should be able to. Oh, yes. At least defend the revolution. Aim high. Aim high. It's a sonnet of liberty. Oh, Bight, what's the greatest sentence? We hold these truths to be self-evident that all men are created equal. And doubted by the equator with certain inalienable rights, among them life, liberty, and the pursuit of happiness. You know, we know it by heart, but we've never really parsed it and really thought deeply about it. I figure for our 250th anniversary, we should do so. Okay, well, let me, let me parse a few things there. It's, you know, a lot of people think of it are undoubted by the creator with certain inalienable rights, but it's unalienable rights. Well, you know, Jefferson in the first draft, which is like here, you can see the first draft. Yeah, we've got a larger copy of it. He writes inalienable, There it is. There it is. And John Adams, who's editing it, transcribes it to unalienable. I like inalienable better. That's the way it is on the Jefferson Memorial. Do they mean the same thing? Yeah. So it's a... Yeah. I mean... So it's a typo? It's a typo? trying to figure out what's the difference. And then I realized it's a transcription error.

You know, they made mistakes.

Flammable and flammable. Exactly. Unflamable. Some people, and I don't know why, but there are some people I've heard recently saying, well, no, I mean, the declaration is poetry, but it's not a founding document for us. They look solely to the Constitution for that.

But if that's the case, and I know arguments

have been made about that recently,

as there have been debates about the equality of humans,

if it's not our founding document, then why is this our 250?

It's a mission statement.
