Paradoxes are not only quip puns (see examples in the Introduction). They often come from philosophy and are present in the academic literature (see Chapter 1). However, they can also serve as action-drivers. Elaborating on the concept of possibilitivity (i.e., perceiving insurmountable challenges as doable; see Chapter 7), Chapter 15 presented various examples of transcending the impossible in the field of social activities. Chapter 16 provided an overview of applications of paradoxical interventions in psychotherapy. Chapter 17 demonstrated paradoxes in life, including the astounding paradox that chaos may play a positive role in various settings.
