“Knowing, then, begins with the shattering of illusions, with disillusionment (Ent-täuschung). Knowing means to penetrate through the surface, in order to arrive at the roots, and hence the causes; knowing means to “see” reality in its nakedness. Knowing does not mean to be in possession of the truth; it means to penetrate the surface and to strive critically and actively in order to approach truth ever more closely.”
