By allowing the group of people whom we call “our loved ones” to continually expand, we realize that this group is actually limitless. It is only narrow-mindedness and a superficial convention that makes us divide people into friends and strangers. The world-traveler soon learns to see in every person he interacts with a potential friend .

There is no real conflict between nationalism and globalism. On the contrary: It is to the extent that a nation becomes more global in its achievements that it becomes admirable.

The culmination of every supreme nationalism is a consummate universalism.

The world-traveler must, on the one hand, be ready (and actually seek) to visit a tribe in the Solomon Islands or stay with Tibetan nomads; on the other hand, he has to be prepared, when it is required, to wear his suit to attend a classical music concert in a big metropolis. Just as an important part of exploring Brazil is to visit its shantytowns, it is an indispensable part of understanding the French culture to eat at a gourmet restaurant in Paris.
