Abstract
Once affirmed that a formal and finalistic theory of action is one of the four pillars of neo‐institutionalism, the author introduces the concept of Freedom of action, which is based on two points: the empirical existence of a scope for action and an information process which determine the choice between alternative actions. He then analyzes different versions of determinism and the distinction between descriptive and practical sentences, and concludes that a theory of action based on the information process has to deal with the structures of teleological thought. In this sense he stresses the practical relevance of the plurality of ends, often conflicting with each other. Finally, he explains how formal teleology is used in his theory of action and how this theory provides methodological achievements for jurisprudence.*
