III. The World as Illusion

It is Lange's conviction that all scientific endeavor that does not limit itself to the evidence of the senses and the logical intellect that combines these elements of evidence must remain fruitless. That the senses and the intellect together, however, do not supply us with anything but a result of our own organization, he accepts as evidently following from his analysis of the origin of knowledge. The world is for him fundamentally a product of the fiction of our senses and of our intellects. Because of this opinion, he never asks the question of truth with regard to the ideas. A truth that could enlighten us about the essence of the world is not recognized by Lange. He believes he has obtained an open road for the ideas and ideals that are formed by the human mind and that he has accomplished this through the very fact that he no longer feels the need of attributing any truth to the knowledge of the senses and the intellect. Without hesitation he considered everything that went beyond sensual observation and rational combination to be mere fiction. No matter what the idealistic philosophers had thought concerning the nature of facts, for him it belonged to the realm of poetic fiction.
