"In this age of mass communication, why do we need to take the time and money to move people across borders to increase understanding? The first and most obvious answer is that communication - visual and verbal - has passed through the filter of the producer. Seeing and hearing through the eyes and ears of another is learning one point of view. It is the difference between looking through a keyhole and walking through an open door for the whole view."
