This paper intends to show what it consists and which is the importance of investigating and offering an answer to the problem of the possibility of the virtue duties. Therefore, we will, at first, approach the problem of the possibility of the virtue duties starting from problems that refer to other a priori synthetic judgments in order to, soon after, indicate the requirements that should be accomplished by the virtue duties so that they are considered possible. This investigation is commited with Loparic's semantic interpretation.
