One of the fundamental questions in the book is how would Dr. King view our progress after 40 years. Sadly I think he would give us a "D"at best. Many of the social and political ills he was fighting in the '60s are still prevalent in the 00's they are just dressed differently.
The other painful reality of the book is that Dr. King was able to function despite being under the CONSTANT threat of death. The man couldn't get up in the morning without thinking it might have been his last. How many of us could handle that type of pressure!
As I said I am only half way through but I would already recommend it to all if you don't mind Brother Dyson's verbosity every now and then.
