This paper, which is methodologically based on Husserl's legacy and Weber's synthesis of systematic and historical sociology, presents the results of Alfred Schutz's intensive methodological reflex in the field of social sciences over three decades. Although his death in 1959 prevented this work from being completed, the internal unity and transparency of the concept permeated the fragmentary work enabled Thomas Lukmann to prepare the work for publication according to Alfred Schutz's own intentions. The work of Alfred Schutz's whole life is marked by a central desire, namely the desire to justify the possibility that the subjective meaning of human action can be determined objectively, ie scientifically.
