In speaking of the human experience of finitude and the need for an ordering towards absolute infinitude, understood as the locus where the nature and identity of man can be truly restored, that is, in speaking of the understanding of the place of the human soul in the hierarchy of the world, recognising its dynamic nature and the need for an ordering towards God, we seek here to present Augustinian cosmology. As well as dealing with the problem of recognising human weakness and dependence, the emptying of oneself through a movement of rupture and distancing oneself from the pursuit of happiness and the inability to overcome the limits of one's finitude, we present Augustinian psychology. Both point, as it were, to a moral philosophy. In this agenda, the theme of spiritual stillness, the horizon of human trajectory, explores, at the same time, Rational Philosophy, Logical Philosophy and Physical Philosophy, according to the classical Stoic tripartition, which was used by various schools and doctrines in Antiquity, subordinating various areas of knowledge to the theme of interiority, elaborating a specific moral philosophy to understand it.
