Just finished reading a non-Lincoln book titled "Man's Search For Meaning" by Victor Frankl
Victor Frankl was a Jewish psychologist and he writes about his experiences inside the Nazi concentration camps of WW 2
It is a very powerful and moving book. My review can't do it justice, so if you are interested read some of the online reviews. http://www.amazon.com/Mans-Search-Meanin...or+meaning
It does have some psychology theory in it near the end, but the majority of the book is his personal witness to the events around him.
Dr. Frankl gives reasons and examples why some people survived the holocaust, while other did not. It's an affordable book, your library may even have a copy.
I highly recommend it.
So when is this "Old Enough To Know Better" supposed to kick in?
