<Shutai-sei> is a vague concept that involves two meanings of "Subjectivity" and "Independence". This concept is concerned with the traditional problem of "determinism and freedom" of human action, and from sociological perspective, offered against social constraint revealed as one of the determinism. <Shutai-sei> as "Subjectivity" is found in A・Schutz's action-theory. It is the autonomous function of "System of Relevance", that constitutes "World of everyday life" which is the cognitive base of action. The other side, <Shutai-sei> as "Independence" found in N・Luhmann's theory depends on "Subjectivity", the function of "System of Relevance". Both of these are given characters of the mechanism of action accomplishment, but on the other hand they may change due to action-theoretical necessity, and present the difference in quality. Therefore we can argue <Shutai-sei> as the given and as the shaped.
