Quite a few political economists advocate the thesis that a Robinson Crusoe — or what amounts to the same thing, a controlled economy — calculates in terms of profits and losses. Otto Neurath (1935)
We are like sailors who on the open sea must reconstruct their ship but are never able to start afresh from the bottom. Where a beam is taken away a new one must at once be put there, and for this the rest of the ship is used as support. In this way, by using the old beams and driftwood the ship can be shaped entirely anew, but only by gradual reconstruction. Otto Neurath (1921)
Finally it should be noted that the picture education, especially the pictorial statistics, are of international importance. Words carry more emotional elements than set pictures, which can be observed by people of different countries, different parties without any protest; Words divide, pictures unite. Otto Neurath (1931)
