The subject of the present work is noema and its structure in various stages of the objectivating process. Despite its great importance, this issue has never been adequately explained, neither by Husserl nor by his followers. The main objective is to provide the theory that would describe the structure of noema and its function without simplifying the case or appealing to non-phenomenological data. This has been achieved by way of analysis divided into four sections. The first provides an overview of (...) noema. The second section is devoted to analysis of the process of objectivation, i.e., how an active awareness of the object in a logical sense is constituted by a series of passive experiences. The third section refers to a noema as found at different stages of objectivation. It explains how the increasing level of activity, which turns out to be a noetic function, causes changes to the structure of a noema. The last section summarises the results and stresses the advantages of the developed theory in comparison with other interpretations, especially those offered by Drummond, Smith and McIntyre. (shrink)
