People like to compare their enemies to Adolf Hilter. But maybe they should compare their clients.

Someone who has given me much to think about in terms of Hitler's use of our tool, rhetoric, to achieve his epic, evil ends is Christan Nicholas Eversbusch, who is a consultant with the Danish speechwriting firm, Rhetor.

Christian is a friend forged in frequent but intense meetings. I've met him three times but we speak as if we've known one another much longer.

So when I told him last week that I wanted to record a bit of wisdom that I saw him deliver at another conference a few years ago—an explanation and demonstration of the elocution of Hitler—he trusted me to present it to my audience in a tasteful way. And in turn I ask you, my trusted audience, to receive it in the instructive way in which it was offered.

What can Hitler teach us about the power of rhetoric to achieve fearsome goals as well as worthy ones? Here's Christian's take on it, which you can put to the test by watching the actual Hitler speech that follows.
