Logotherapy was developed by Neurologist and Psychiatrist Viktor Frankl and

is based on the premise that the primary motivational force of an individual is to find meaning in life.​Described as "the Third Viennese School of Psychotherapy"

along with Freud's psychoanalysis and Adler's individual psychology.

​Logotherapy is based on an existential analysis focusing on Kierkegaard's will to meaning as opposed to Alfred Adler's Nietzschean doctrine of will to power or Freud's will to pleasure.Rather than power or pleasure, Logotherapy is founded upon the belief that striving to find meaning in life is the primary, most powerful motivating and driving force in humans.
