The Noon Universe was described by the authors as the world in which they would like to live and work. It became highly influential for at least a generation of Soviet people, e.g., a person could quote the Strugatsky books and be sure of being understood. At first the authors thought the Noon Universe would become reality "by itself", but then they realized that the only way to achieve it was by inventing the High Theory of Upbringing, making the upbringing of each person a unique deed.
