In Aristotle’s Greek ancient universe it is “a special set of material substances: the ether, the pneuma and the beginning of the transparency and the light, hot or brilliant all of them, all assets and they are not submitted to the qualitative change, which function consists of acting as vehicles and intermediaries across which the immaterial thing relates with all other material things and acts on them. Thereby, the immobile engine acts on the totality of the things by means of the fact of putting in movement the skies consisted of ether, and the soul acts on the body and reports with it by means of the pneuma.” Armstrong noticed that this idea has a great historical importance: it comes from the pre-Socratic thought and constitutes the immediate source of the stoic doctrine of the pneuma, which is one of the essential sources wherefrom there come the ideas of the fire or of the light as the material formative and active principle that we find then in Plotinus, and that for his influence, it will persist in the medieval philosophy. In this occasion we are interested in emphasizing how this current generated in the Greek world will persist in San Augustine's philosophy, although with a difference of emphasis, namely, the way of the self and subjectivity.
