A groundbreaking exploration delves into the intricate process by which a baby's chaotic sensory world evolves into a structured reality, differentiating inner experience from outer objects. This transformation, starting at infancy and continuing through childhood, involves learning to discern the objective world, distinguishing one's own perceptions from those of others, and mastering language and communication. The result is an intricate duality between the inner realm of subjective experience and the outer world of physical objects, with both realms interconnected and complementary. This fascinating investigation raises philosophical questions about the nature of consciousness and its relationship to matter, suggesting that they may be two sides of the same existence. The study's findings are likened to a mirror reflecting reality, with experience serving as the boundary between the inner and outer worlds, encompassing the entirety of reality within it while occupying only a small fraction of it by its own account.
