Among the issues in the field, the outher tries to report and explore these philosophical and logical conflicts: the gap between "is" and "ought" (The problem of Hume) and also some solutions proposed to solve it and some other paradoxes of logic of duty, the moral logical principle that "ought requires the ability" and its logical analysis, naturalistic fallacy (and also reasoning throughe open question),and issues or conflicts concerning the practical and moral deduction (in the context of the role of principles in moral reasoning and also the problem of weakness of moral will).
