Abstract

Whitehead’s process philosophy offers a wide range of speculatively generalized concepts that allow for an application in transdisciplinary research. The notion of projection is an often-overlooked detail of his philosophy that not only appears in his far-reaching theory of perception, but also constitutes an integral part of his theory of extension as the formal foundation of his metaphysical project. His perceptive theory relies on the idea of projection as the fundamental ontological relationship that lifts the past into the present. Projections of sensa describe one side of the ‘double-barreled’ theory of perception and the spatial relations of the contemporary world. The microscopic projection is just as fundamental for perception and for the integrity of a relational theory of becoming, as the perceptual projection is necessary ingredient for symbolic modes of experience. The simple projection in the mode of presentational immediacy is the basis of temporary stability of events and of any perceptual situation in the biological realm. Whitehead was aware of the possible misconceptions that this term might lead to. Discussing his remarks on the hierarchical variety of different modes of projection can resolve those misconceptions and throw a new light on the importance of projection for interdisciplinary inquiries.
