Abstract
The problem of epistemological reflection has many aspects. Epistemology and logic are not the only disciplines in which it is studied. The life sciences, social sciences, and certain of the theoretical technological disciplines - all have a direct bearing upon it. In studying this complex problem it is desirable once again to seek a clarification of the fundamental features of the basic "unit" of reflection, employing the data of these sciences to this end. This is desirable not only with respect to specialized studies of the reflection problem, but also because of the trend toward combining them, as, for example, in efforts to model mental functions in cybernetics
