Against the total and ultimate meaninglessness of life
Viktor E. Frankl on his Man’s Search for Meaning repeats this quote a few times.
On how prisoners need a aim in order to strengthen them to bear the terrible how of their existence:
He who has a why to live for can bear with almost any how.
The challenge we all face in our existence (to find a why) is the challenge of every protagonist of every story.
If a book is a hopeless prison for its hero, what is the ultimate goal that will give the hero the strength to pull through al the adversities.
