Man's Search for Meaning is the author's recollection of his days spent in Auschwitz and other Nazi concentration camps during World War II. In the book, Viktor Frankl introduces his theory called logotherapy, which states that humans are driven by what they find meaningful on a personal level. The theory opposes Freud's view that humans are hedonistic creatures and Adler's view that power is the driving force of the human race. In Man's Search for Meaning Frankl tells us about his observations in the camp. He noticed that the longest survivors in the camps were those who managed to have a sense of control over their dismal surroundings. Not the ones who were strong physically. He found that the capability to decide your attitude in a given situation is the greatest strength in a person. The author portrays the true art of living in a profound way, giving you a whole new perspective on life, no matter what your circumstances. The book is a story of hope that has been one of the most influential books in the world.
