Even in the horrors of a concentration camp, humans retain the freedom to choose their response to suffering, showing how a life oriented by purpose can endure extreme hardship.
The fundamental driving force of human behavior is the search for a unique and specific life purpose, rather than the pursuit of momentary happiness or dominance.
The last true human freedom is the ability to choose one's attitude and internal response regardless of external, unchangeable circumstances.
Meaning can be discovered through engaging in creative work, experiencing love for another person, or adopting a courageous stance in the face of unavoidable suffering.
