For this article, Goethe's Faust will be compared and contrasted with Kant's, the "Foundations of the Metaphysics of Morals" and the relationship between human reason and emotion will be examined. Goethe's Faust is considered one of the greatest dramatic poems and is divided into two parts; in the first half he uses reason and for the second part he uses passion. Even knowing that the story is based on a medieval man or a medieval legend who sold his soul to the devil, we can actually say or treat this text as a kind of alienation of modern man and the need to make part of the world where he lives. At the other end, Kant's “Foundations of the Metaphysics of Morals” discusses reason and emotion. For example, Kant wants people to think for themselves, ask why they think, what they think, and question others before relying on them. Faust represents the “Enlightenment scholar” that Kant says we can be and he is unhappy, claiming that thought is not an actor and believes that nothing can fill his life and that henceforth all his joys will come from the world. In Faust's adventures between light and darkness (light as for example heaven and darkness as hell), in the search for happiness or for Kant the search for morality, man must learn to conquer the little things or elements of your own nature and always live constructively with the challenges and objectives imposed on you. As Kant said, to find moral happiness, people must stand up for their own beliefs and they do not need others to be a good moral person. So, for this article, the following paragraphs will compare and contrast Kant's ideas in the “Foundation of the Metaphysics of Morals” and Goethe's ideas in the poem Faust. For Kant in the “Foundations of the Metaphysics of M.... .. middle of paper ...... makes you cold; Dear children, I am not offended; Remember: the Devil is old, grow old yourself and he will make sense! (Goethe). This proves that the deceptions he had during his adventures made him grow as a person, contrasting with Kant's ideas such as “Have the courage to use your own reason – that is the motto of the 'enlightenment' (Kant). What Kant and Goethe mean with these quotes is that if one uses reason, one will become a better person with better morals. So what both works are trying to tell us about human reason and emotion is that Kant was more direct with his moral ideas and Goethe, showing us with the poem Faust, that even in a dramatic way, we can use this reason and emotion, but it will only depend on you, each of them will be better for you. As Faust already said, “As soon as you have confidence in yourself, you will know how to live”
