Here there exists a direct ignorance, where the parameters of a problem are clearly delineated. Thus, the mind-body problem seems to be able to transform itself into an ensemble of questions which may be solved by attributing a cerebral mechanism to each cognitive act. But we have no idea of the way in which the cognitive act might be separated from personal experience. This inevitable mind-mind problem represents an oblique ignorance which is at once more subtle and extraordinary. Phenomenology is a particular type of study that concerns our conscious being.
All phenomenological reflection reveals a variety of mental content as well as intentional content.
Phenomenological reduction is a method which, unlike introspection, draws on ordinary reality and permits the structure of our conscience to be described.
