Only the misfortune of exile can provide the in-depth understanding and the overview into the realities of the world.
Human life is so strangely constituted that even perfected intellectual understanding combined with the richest experience is incapable of conquering innate weaknesses. Even if it thoroughly analyzes itself, psychology (and this is one of the dubious aspects of psychoanalysis) can, to be sure, recognize its flawed native characteristics, but it cannot eliminate them. Understanding (them) is not the same as overcoming (them) and, again and again, we see the wisest of human beings helpless in the fact of their small follies which everyone else observes with a smile.
In some mysterious way, once one has gained an insight into human nature, that insight grows from day to day, and he to whom it has given to experience vicariously even one single form of earthly suffering acquires, by reason of this tragic lesson, an understanding of all its forms, even those most foreign to him, and apparently abnormal.
