In The 3D Mind trilogy Jacques Chevalier explores the links between brain science, studies of symbolism, and debates in ancient, modern, and postmodern philosophy to shed light on how the brain and signs in language actually interface. He pursues this dialogue across disciplines through an elegantly simple plan that mirrors the three-dimensional structure of the brain, proceeding from the sagittal (right-left) to the axial (top-down) and the coronal (front-rear) dimensions of neuropsychology. Half-Brain Fabled and Figs in Paradise starts the trilogy on the lateral plane and explores the tendency of each hemisphere to specialize but also to complement or supplement the other hemispheres.
