Unselfconscious self-assurance. As Richard Logan found in his study of individuals who survived severe physical ordeals—polar explorers wandering alone in the Arctic, concentration camp inmates—one common attitude shared by such people was the implicit belief that their destiny was in their hands. They did not doubt their own resources would be sufficient to allow them to determine their fate. In that sense one would call them self-assured, yet at the same time, their egos seem curiously absent: they are not self-centered; their energy is typically not bent on dominating their environment as much as on finding a way to function within it harmoniously.
