The present paper consists of two parts, in which dealing with the functions of institutions we are mainly looking for the answer to the question, at a highly abstract level of analysis, how the institutions determine the actions of individuals and thereby phenomena which can be interpreted as summaries, systems and consequences of actions. In the first part of the paper, published in the previous issue of this periodical, the author made a distinction between the elementary functions of institutions, and outlined the main features of the functions of institutions concerning actions. Then he made a distinction between the normative and positive functions of institutions, and emphasized that to the certain institutions the prevalence of normative functions and to the social institutions which are prevalent in the so-called sphere of social life the prevalence of positive functions theoretically correspond. In the second part of the paper, published in the current issue, the author first points out that the distinction between the normative and positive functions is essential particularly because the positive functions of institutions correspond to the institutional norms only contingently, thus they may be functions corresponding to the institutional norms, or differing from the institutional norms. After that a distinction is made between the functions of institutions corresponding to explicit intentions, those corresponding to hidden intentions, and non-intended ones. Finally, he deals with the issue that on the one hand the distinction between the normative and positive functions of institutions, and on the other hand, the intended and non-intended functions of institutions do not correspond to each other, but there are certain connections between these typical functions.
