'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.'
