After having been shipwrecked, Robinson Crusoe took advantage of the fact that the ship was stranded out a short distance from the island. While he was searching through the ship, he found a heap of coins sitting in the ship.
He recognizes the money is worth nothing to him. He is all alone, and even if there were savages on the island, they would not take gold and silver as payment for their services. If a ship came to pick him up, they would probably expect his gold as payment for delivering him, if they even bothered to do so. But he takes the money anyway. Why?
The love of money is what got Crusoe in that predicament after all. He was sailing to Africa to get slaves and expected to return to his plantation and become rich. Was it old habit setting in? Probably. If I were to find money lying around, I would probably take it for sentimental value and a reminder of the civilization I had been raised in, or since it was coinage, to melt down and turn into something more useful, but it seems that the only reason Crusoe took the money was for the money’s sake.
