The Will to Meaning contains three short lessons in logotherapy, the system of psychotherapy Frankl pioneered that transforms despair into hope.'As logotherapy teaches, even the tragic and negative aspects of life, such as unavoidable suffering, can be turned into a human achievement by the attitude which a man adopts toward his predicament. In contrast to most of the existentialist schools of thought, logotherapy is in no way pessimistic; but it is realistic in that it faces the tragic triad of human existence: pain, death, and guilt. Logotherapy may justly be called optimistic, because it shows the patient how to transform despair into triumph.'
