Observing human life and the quest for meaning from a humanistic, existentialist perspective, the present book endeavours to formulate an answer to the question: "What is Perpetuum Mobile?" How do we use our individual unique awareness and experiences in the service of a global quest for meaning and purpose? As therapists with unique life experiences and professional practice experience with Viktor Frankl's Logotherapy, we employ a phenomenological hermeneutic inquiry, looking critically at texts we previously compiled and more recently presented, and discerning, inferring, and concluding our observations and their implications.
