The third dimension would be that of philosophical reﬂection, which develops as a thought of the Same; it forms a common plane with the dimension of linguistics, biology, and economics: it is here that we may meet, and indeed have met, the various philosophies of life, of alienated man, of symbolical forms (when concepts and problems that first arose in different empiricaldomains are transposed into the philosophical dimension); but we have also encountered here, if we question the foundation of these empiricities from a radically philosophical point of view, those regional ontologies which attempt to define what life, labour, and language are in their own being; lastly, the philosophical the human sciences dimension and that of the mathematical disciplines combine to define another common plane: that of the formalization of thought.
