The issue of the practical mind is a clear landmark as it formed a common element in both philosophy, theology and the principles of jurisprudence, and this issue is the cognitive field that relates to human actions and behavior, what should be done and what should not. Within the folds of the research that dealt with the recognition of the sovereignty of the mind and its ability to rule in isolation from the law, two paths appeared in the fundamentalist thought. The independent objective of these perceptions, and that their existence is not a consideration of the mind and this is what the mental school adopts. It should be noted that the two paths are based on rationality and ugliness, noting that they are a branch of the rule of reason and its independence in ruling apart from Sharia, and thus the size of the distance between the two paths becomes clear. Keywords: the nature of the mind, divisions of the mind, perceptions of the practical mind.
