III. The World as Illusion

Mill points out that the thoughts, which in a certain age appear as absolutely certain inner experiences, are nevertheless reversed in a later time. In the Middle Ages it was, for instance, believed that there could not possibly be antipodes and that the stars would have to drop from the sky if they did not cling to fixed spheres. Man will, therefore, only be capable of the right attitude toward his knowledge if he, in spite of his awareness that the logic of the world is expressed in this knowledge, forms in every individual case his judgment through a careful methodical examination of his conceptual connections guided by observation, a judgment that is always in need of correction.
