The main characteristic of human reason is questionable. It is unable to provide the answers to the questions asked. Even though human reason is based on logic and evidence rather than emotion, its ability to explain certain phenomena is incomplete. It has come with various principles to explain this experience. The questions cannot cease to exist; it employs principles that human consciousness cannot resist. Kant’s criticism is that human reason has numerous errors. In the efforts to conceal those errors, the principles are limited and no longer subject to logic or empirical test.
There was a time when metaphysics has crowned the queen of science. Metaphysics explains the first principle of things, concepts, and other abstracts. It was taken over by human understanding and reason since it allows people to explain concepts through the evidence gathered and logic. Human reason planted doubt on the origin of metaphysics which led to the depreciation of the latter. Metaphysics is now considered ancient and was rendered dark, confused, and unserviceable.
However, this conflict between metaphysics and human reason brought about indifference in science. Kant explains that this knowledge, if attainable, should be used to explain a phenomenon that needs attention and reflection. He says that this knowledge of human reason can be used to explain the origin of metaphysics, its extent, and limits reflecting on his principles. Kant clearly states that the problem with metaphysics, as with any other science, ‘is to explains how things happen.’
Kant says that he does not avoid the question directed to reason due to the insufficiency of human reason. On the contrary, it answers them with satisfaction. Even though human reason conflicts with itself, Kant answers all questions according to principles without dogmatism or theoretical knowledge. His main aim is to answer the questions in completeness. Therefore, to fully explain the principle, all questions must be answered. If a principal has one question which cannot be answered, they have no choice but to reject the Principal.
For certainty, he rejects the idea of opinions in his investigations; therefore, everything resembling a hypothesis should be treated as counterfeit. The reader has the right to demand logical and aesthetic clearness and other concrete illustrations which should be provided. He opts to develop principles to explain the metaphysics of nature, which would be richer content than the critique of human reason with reliable conditions and sources. Human reason has the peculiar fate of being burdened with questions that it cannot ignore because they are problems that human reason has given it, but also questions that it cannot address because they are beyond the its scope.
