The author discussed about the psychological effects of being completely dehumanized; of losing even your name, and becoming simply a number. Also he disscusses the effects of not being able to contact loved ones, or even know is they are still living. Another issue that Dr. Frankl talks about in this book is the idea that none of the prisoners of the concentration camp had an idea as to when there imprissonment would end (if ever). Thus, they lived without any "hopes". Dr. Frankl discusses how people can find meaning to life in these conditions. He also describes how finding meaning in life, or a reason to live, was extraordinarilly important to surviving the camp.
Too difficult to read because of heavy technical terms.May be professional psychologists and psychiatrists can appreciate it better but a person not from a different background will find this book uninspiring.
