This thesis discusses about Religious Ethic Concept by comparing the thought Ibn Miskawaih and Immanuel Kant. Both of them were ethic figures whose thoughts still influenced until nowadays. Ibn Miskwaih was famous as the father of Islamic ethic, because he was the first Muslim figure who discussing about ethic philosophically in which Muslim thinkers previously never discuss about ethic in philosophical field. According to them, it was sufficient referred to the Qur’an and Hadits as ethic foundation source. However, Ibn Miskawaih was bravely to arrange Islamic ethic concept that was based on Greek philosophers thinking, yet still stayed on Islamic law sources, namely the Qur’an and Hadits.
Meanwhile, Immanuel Kant was western philosopher in the 18th century whose thought is being discussed up to now. As a western philosopher who used rationality as basic thinking, he also used religious values in his thinking formation, especially in studying about ethic. According to him,ethic came from God, while human as God’s creature whose mind had autonomy right to have ethic in line with the law he made. It did not mean that human was free to do everything he wanted, but here was actually placed the sacred of moral action itself.
In this thesis, the researcher has limited the theme on the thoughts of the two thinkers about religious ethic, although Ibn Miskawaih for example discussing also about other themes in his opuses, such as the soul healthy, love, friendship, and etc. and so does Immanuel Kant who discusses about state, religion, and etc. However, the researcher only focuses on religious ethic. Afterwards, the researcher tries to compare their thought and later will be discussed about its similarities and differences.
After comparing their thoughts, apparently there are similarities in concept, although it is delivered in different thinking method. For example, in the ethic concept, both of them agree that the deed which including in ethic category is the deed done without any consideration, motives, and certain purposes except for good values itself. So does in the other topics, both figures has many similairty except in God’s existence topic. For Ibn Miskawaih everything in this world comes from the emanation of God. So, God is the sources of everything in this world. But, for Immanuel Kant, God is not the prime cause of everything in this world because if God become the prime cause, it means God include the part of this world. So for Kant God is positioned on the intellectual experience.
