This book explores the concept of Objective Mental Reality (OMR)--a fundamental, intersubjectively formed symbolic layer of consciousness. In Part I, it delves into foundational psychological constructions such as the soul, mind, consciousness, and intelligence, as well as the nuanced roles of personality, beliefs, and cultural codes. These entities are examined not only as subjective experiences but as components of a shared mental reality that can be studied objectively. The section further investigates the processes through which the entities of the psyche are constituted and reveals their role in shaping OMR. Parts II and III address specialized domains of OMR -- including religious faith, mathematics, art, and media -- as well as OMR's relationship to time, language, and artificial intelligence. The book proposes a new scientific paradigm in which the anthropomorphic world is understood as a product of collective mental creativity constituted within the OMR of society. Through and by means of OMR, humanity comprehends the universe and becomes aware of its own nature, while the psyche transforms from a passive mirror of being into its active co-creator.
