Abstract:

The question of how “the rule” determines the action which is compatible with itself holds a central place in Wittgenstein’s last term studies. There is more than one answer to related topic in Philosophic Investigations. According to first answer, what determines the meaning of rule is grammar. As to the second is what determines the meaning is usage of this rule or word. The rules related to mathematics, logics, language and colors are analytic and there is no gap between the rule and its practice. Logic and grammar exactly determine the act compatible with the rule. Therefore with the question of what action compatible with the rule is not encountered. In this area, probability and suspicion are excluded, there is no place for commend as well. Legal rules do not mostly consist of analytic words and concepts. They, thereby, are open to different practices and commends. This difference prevents the usage of Wittgenstein’s rule concept to include all legal rules.
