If we restrict ourselves to the pure phenomenology of cognition, then we will be concerned with the essence of cognition as revealed in direct 'seeing," i.e., with a demonstration of it which is carried out by way of 'seeing" in the sphere of phenomenological reduction and self-givenness, and with an analytical distinction between the various sorts of phenomena which are embraced by the very broad term "cognition." Then the question is as to what is essentially contained and grounded in them, from what factors they are built up, what possibilities of combination can be found while remaining purely within their essential natures, and what general interrelations flow from their essences.
