The initial task is, I think, to eliminate imprecise thought processes which conceptually deceive us into handling people as we handle money or goods once we commence the process of aggregation. In order to illustrate this I would like to relate an experience which can hardly be unique. When I was three or four years old my father tried to teach me the principles of banking and we trotted along to the local establishment to deposit what I had accumulated in my savings box, including a very shiny silver crown. The next day I insisted on walking back to the bank to make sure that the people had really guarded my money. The clerk was very understanding and showed me the correct mix of coins. But the shiny crown was not among them and it could not be produced. I decided that savings banks did not really save money (Hägerstrand, 1970: 9).
