One of the most important books in the legacy of Viktor Frankl, an outstanding psychiatrist and psychologist of the 20th century, the creator of logotherapy (meaning therapy). For this book, Frankl received a doctorate of science, it was accepted as a dissertation. In this book, the author puts forward his theory of the “structure” of man, the levels of his being, including that same spiritual principle. This idea helps to holistically perceive the complex human phenomenon and helps to understand its nature. Frankl calls conscience, irrational and intuitive in nature, “subconscious god.” Conscience and responsibility are inherent in both religious and non-religious people. The difference lies in the different answers to the question of to whom a person is responsible for realizing the meaning of his life. For a religious person, this final authority is God, this is his interlocutor in the internal dialogue, to whom the most innermost thoughts turn in the most difficult times, God is essentially a personalized conscience. At the same time, it is not necessary to belong to any confession and somehow adjust your personal conscience and faith to the requirements of a particular religion. Like all the works of Viktor Frankl, “The Subconscious God” is about the meaning of life, and conscience is the beacon that helps determine the meaning and find the right solution in any specific life situation. For whom the book will be of interest to those who have already read the books of Viktor Frankl, useful to existential psychologists, clergy and students of psychology, will help those who are concerned about issues of religiosity in a philosophical and psychological vein.
