Schütz, thus clarifying a system of concepts that seems to be of some relevance for the development of a framework for semiotics. The system of semiotic concepts proposed by A. Schütz, however, is not in a state in which it can be used or studied by nonphenomenologists without problems. We try to remedy this deplorable situation by giving the first steps of a reconstruction of his ideas (a reconstruction as it is understood in analytical philosophy)
