Kant On The Idea Of ​​metaphysical Reconstruction Explore

Metaphysics is one of the basic philosophic issues disputed endlessly for a long period .At the times of ancient Greece, Parmenide's "existence", Plato's "Idea" and Aristotle's "metaphysics" are all researches on metaphysics, which is stipulated as the pursuit on the last arche. However, during the 2000 years after Aristotle, the issue of metaphysics has not been solved perfectly and its reputation has been slandered by philosophers of modern times. To dogmatists, a series of metaphysics issues such as the world's arche and the argument for the existence of God could be solved by human reason independently and is's not necessary to rely on any experience. But scepticsts doubted about it and decided to cancel metaphysics.The antagonism of dogmatism and skepticism, esp. Hume's crossexamination on dogmatism has inspired Kant's thinking on metaphysics. How metaphysics is possible an a branch of science? Kant criticized human beings could recognize appearance field only and they couldn't recognize thing-in-itself . Human beings have three kinds congenital recognition abilities of perceptual, understanding and reason. The unity of perceptual relays on understanding, the unity of understanding relays on reason and reason arche becomes truth's last standard and eternal tendency of recognition. But reason arche only havethe function of leading understanding and pursuing for the biggest limit's unity of searching for experience knowledge and can not function in experience field. Though it is completely closing in on, it is not the active noumenon to Kant . To Kant, the true active noumenon can not be recognition, but human beings' practical reason, that is morality which differs from scientific knowledge .Then, Kant's thing-in -itself comes into practical reason of ethics from reason arche of epistemology and becomes moral noumenon. To Kant , this is thing-in-itself itself. The theory of thing -it-itself is both the end of Kant's epistemology and the bridge to Kant's ethics .The whole system of critic philosophy transitions to this moral substance and then moral metaphysics ins established . It wants to research life's journey's meaning and end and gets human nature's freedom and perfection.Kant's introspection on metaphysics is novel, we should research it critically and hope , that we can get some voluable guidance .Kant's philosophy has profound and lasting influence on later philosophy. So it is more important to study and criticize Kant's philosophy with militant materialism.
