“Look here”, said the old seafarer and rolled out a map. “This here is the Island of the Blissful.” His grandson regarded it attentively while the man stood up and took another map from the shelf. “And this here”, he continued while he unrolled this second map, “is the Island of the Ill-Fated.” “But that’s exactly the same island!” exclaimed the young man. “Perhaps it is the same, and perhaps it is not”, said the old man in a mysterious tone. “But I can tell you this much: The maps were drawn by two different cartographers. Both have visited the island. One went to all the bleak and desolate mountains on the island and measured all the spaces. The other went to all the beautiful, fertile places, and measured the island from there. Look here: they have also drawn in the paths along which they wandered. Whoever makes his way with the first map, looks from one beautiful peak to the next, and the dreary areas are hidden by the beautiful mountains. However, whoever makes his way with the second map, looks from one desolate peak to the next, and the beautiful scenery landscape remains hidden behind them.”
