Carl Jung said, in one of his interviews from 1959, 'Man Cannot Stand a Meaningless Life'. Victor Frankl, in his book, 'Man's Search for Meaning', says that when people have a why, they can endure any how. He also says that every age has its own mass neurosis, and the neurosis of our age is the neurosis of meaning. He developed his own school of psychotherapy, and his approach towards psychoanalysis, which he called 'Logotherapy'.He proposed that the primary motivation behind all human actions is a desire to meaning. He has written over 20 books in German on the same. This is me just trying to scratch the surface.
