One of the most important debates in anthropology is the relation between emotional and cognitional aspect of human. In this article, in the first part, I try to explain the concept of the "reason" and the "heart"-as two central concept in Islamic developmental anthropology- Focusing on "correlation" and "unity". In the second part, I try to illuminate relations between the "reason" and the "heart" as reviewing the "receptacle", the "equivalent" and the "activity". In The end, focusing on "Heart states", I present a model in which "Live heart" and "Dead heart" is explained based on "reasoning" and "ignorance" in order to explain that how the higher levels of the heart require the higher levels of the reason and the inverse. Therefore, the intensity of reasoning as establishing a "more relevant" relationship between beliefs and reality, and the subjection of emotions and action in cognition, on the other hand, will lead to the improvement of the degree of the heart. In addition, the correlation between the states of heart and the degree of rationality in the Islamic approach suggests that knowledge and practice of knowledge are in the subordination of human emotional states.
