Within the three parts of the article, the first one in a elucidation of the concept of "meaning" characteristic of the intersubjective action. With that aim, on the subjective side, the project and the motive of the agent are used; and, on the objective side, the generalised typifications of the meaning are used. In the second part, irreductible features of the intersubjective action and its different modalities are examined. Finally, the mediations which take part in the intersubjective meanings are considered, taking as starting point the original temporality of the consciousness.
