AERTSEN, J.A., Natura en Creatura, 1982, p.72, expresses this as follows : "Het zekere weten verlangt een 'fixatie' van de dingen in hun specifieke bestand. Het particuliere valt buiten de eidologische limiet."
Translation : Certain knowledge [that is, knowledge that is certain] demands a fixation of things as to their specific content. The particular falls outside the eidological limit.
