Viktor Emil Frankl M.D., Ph.D. was an Austrian neurologist and psychiatrist as well as a Holocaust survivor. Frankl was the founder of logotherapy, which is a form of Existential Analysis, the "Third Viennese School of Psychotherapy". His best-selling book, Man's Search for Meaning (published under a different title in 1959: From Death-Camp to Existentialism, and originally published in 1946 as trotzdem Ja zum Leben sagen: Ein Psychologe erlebt das Konzentrationslager), chronicles his experiences as a concentration camp inmate and describes his psychotherapeutic method of finding meaning in all forms of existence, even the most sordid ones, and thus a reason to continue living. Frankl was one of the key figures in existential therapy.
"What man actually needs is not a tensionless state but rather the striving and struggling for some goal worthy of him. What he needs is not the discharge of tension at any cost, but the call of a potential meaning waiting to be fulfilled by him."
"If architects want to strengthen a decrepit arch, they increase the load that is laid upon it, for thereby the parts are joined more firmly together. So, if therapists wish to foster their patients' mental health, they should not be afraid to increase that load through a reorientation toward the meaning of one's life."
