Edward Hoffman's article about Victor Frankl, "A Voice for Life," can be found here
"Much to Freud’s scorn, Adler optimistically taught that kindness is innate in human nature and could be effectively nurtured by good parenting and empathic education.
During the 1920s, Frankl became an ardent Adlerian, and then trained for a specialty in psychiatry-neurology. His patients included many Austrians forced out of work by the Depression and feeling hopeless. When they heeded Frankl’s guidance to initiate volunteer work and focus less on their own woes, their depression usually lifted. Frankl thus became convinced that our sense of daily purpose is a vital trait.
In his final decades, Frankl spoke out authoritatively against physician-assisted suicide."
