“Many of us do not believe that it is truly possible to see the whole world in the same way as we travel and see, say, Italy or Spain. However, if we pretend for a moment that there are no borders separating one country from another, if we actually realize that these borders are nothing but imaginary lines drawn on maps and in historians’ heads, we may easily come to view our planet as one country, one destination – as the moon or Mars were when we first set out to explore them.”
