As early as 1929 I had developed the concept of three groups of values, or three possible ways to find meaning in life - even up to the last moment, the last breath. The three possibilities are
1) A deed we do, a work we create
2) An experience, a human encounter, a love
3) When confrontonted with an unchangeable fate (such as an incurable disease), a change of attitude toward that fate. In shich cases we can still wrest meaning from life by giving testimony to the most human of all human capacities: the ability to turn suffering into human triumph.
