What does 'perspectivity' mean? A discussion with a view on Leibniz

The philosophical idea of perspective draws on two different cultural techniques of representation: on the one hand, the central perspective painting technique of a fictitious three-dimensionality that works with geometric projection from the perspective of the viewer in front of the picture. On the other hand, the cartographic principle of knowledge visualizations in the form of maps, diagrams, and schemas, which shows two-dimensional structural images without fictitious three-dimensionality from a bird's eye perspective. The central perspective representation embodies the first-person perspective, while the cartographic representation embodies the third-person perspective. It is well known that Leibniz introduced perspective as a philosophical concept - concentrated in his theory of monads: the monads incessantly generate local representations of the entire universe. Less well known, however, is how Leibniz, in the development of his concept of perspectivity, refers to the interplay of both forms of perspective in order to show why perspectivity and universality not exclude but rather include each other. This has far-reaching implications for the understanding of Leibniz's metaphysics and epistemology.
