A very particular dynamic of relationships is often responsible for turning great personalities into social disasters. Socially, success requires specific qualities that have nothing to do with the level of personal development. There are hidden rules, some of which cannot be understood without cynicism, and not observing them can be fatal. Within a group, it is impossible to establish intimate relationships, and sincerity has a relative value. One must always act according to what is convenient, something that, for some individuals, is simply unnatural. Thus, much of what is sometimes shocking in some biographies should not cause much of an impression.
