Good thought is the core problem of Kant ’s moral philosophy and an important idea to understand Kant’ s moral philosophy.On the basis of combing and analyzing previous research,this paper will reflect the importance of the highest moral importance.Then this paper is divided into three parts.The first is the exposition of Kant’s free will,the certain free will is the basis of goodness.Thus we should first realize that freedom,that is,people are perceptual beings,and rational beings,establish free will and lead to the unconditional moral law,so we should determine that people are free,have the ability to pursue happiness and interests,but we cannot do what we want,so formulated the moral law,follow the moral law to achieve the hope of good.Secondly,for the best,virtue is the supreme good,which cannot meet the perfect needs of people.However,the pursuit of people’s will also has factors of happiness.Only by happiness into the good can constitute the full good is the best good.However,the consistency of virtue and happiness cannot be realized in reality,which is the two-legal opposite of practical rationality.So leading to the supreme goodness requires the presupposition of God and soul immortality,but these two presets will be valid under the premise of free will.So it was true in the other world.Finally,the possibility of goodness leads to religion for the reason that people are limited rational beings who cannot realize the limit of morality in a finite life.Therefore,the premise of God.Then here mainly discusses the relationship between morality and religion,whether morality necessarily leads to religion. |
