The authors develop new perspectives on the image and word as an articulated dense system, presenting them in the form of the instructive model of the diagram. Diagrams are amalgams hybrid constructions of knowledge. To be intelligible as a means of understanding, diagrams must also be seen as pre-existing elements of the inner world. Diagrammatic thinking reveals cross-references that enable relational, active decision-making.
