Double Negative Confusion

While reading Greg Mortenson's Stones into Schools yesterday, I came across a sentence with a problem. Before I share that example, please let me say that Greg Mortenson is an incredible writer. It is amazing to me that he can be the unique humanitarian and educator he is and also create fascinating descriptions of some of the starkest places in the world.

Here is the sentence:

Nothing takes place inside the Corridor that does not escape the knowledge of these three "big men."

I read this sentence two or three times, trying to decide why it bothered me. Greg means to say that nothing escapes the knowledge of these three men. By adding NOT to the sentence, he creates a double negative that makes the meaning the opposite of what he intended. Also, THAT is misplaced in this sentence. It should be written as follows:

Nothing that takes place inside the Corridor escapes the knowledge of these three "big men."

Having pointed that out and clarified it, I want to suggest that, if you have not read Three Cups of Tea, which is on the reading lists of several branches of the U.S. military as well as numerous universities and community libraries throughout the country, you have missed a powerful message about "last-place-first" opportunities in our world. You have also missed an enjoyable read and an incredible true story. Stones into Schools is the sequel. http://www.gregmortenson.com
