The article reconstructs main topics presented by Husserl in his “D 17” research manuscript entitled Foundational Investigations of the Phenomenological Origin of the Spatiality of Nature. The author claims that in the “D 17” manuscript Husserl introduces a non-idealistic concept of constitution, i.e., he understands constitution as a correlation of the ground (Boden), living body, and a perceived object. A phenomenological analysis of the phenomenon of the ground, however, leads to generative phenomenology which introduces intersubjectivity and history into the process of constitution.
