Thor Heyerdahl

A civilized nation can have no enemies, and one cannot draw a line across a map, a line that doesn't even exist in nature and say that the ugly enemy lives on the one side, and good friends live on the other.

Civilization grew in the beginning from the minute that we had communication - particularly communication by sea that enabled people to get inspiration and ideas from each other and to exchange basic raw materials.
