What never fails to impress is that an extraordinary nature emerges from a barren cradle, rising as if without stimulus and starting from itself, completely overcoming all circumstances. In early cases, the phenomenon borders on the inexplicable. The most frequent occurrence, however, does not fail to impress. In this one, a careful analysis always shows the action of a centripetal force, which with greater or lesser intensity directs, not to say impels, the vocation and the resolution to externalize it. In this way, the process always seems to culminate at a point from which the past becomes strange but justified, although the origin of such a decisive motivation remains a mystery.
