The Unexpected is not the Inevitable. The world of the events is the world in the three dimen-sions of the Uncertain, of the Unexpected and of the Inevitable. What we consider inevitable can sometimes be nothing more than a lack of "mastery" of the unexpected. Cultivating capacity of reflection and imagination is therefore indispensable for being able to think about the world of events with a wide field and clear eyes, with clear vision. Knowing how to think, as a training aim, , means not only "clear mind", but also "solid psyche" and "peaceful spirit". The solid psyche requires deeper knowledge of the feelings that inhabit and animate us (it is "sentimental education"). The serene spirit requires wise practice of the ethical foundation that guides the path in the life: that is, in the world of what "happens" in the three forms of the Uncertain, of the Unexpected and of the Inevitable.
