Viktor Frankl, a Holocaust survivor and founder of logotherapy, emphasized the importance of finding meaning in life as the primary motivator for humans, contrasting his views with those of Freud and Adler. Logotherapy seeks to help individuals discover meaning through creative deeds, experiences, and attitudes, even amidst suffering. Frankl's key message is that life can hold meaning even in the most painful circumstances, encouraging individuals to cope with suffering and seek a purposeful existence.
