"In order to elucidate especially and most clearly the origination of this error (...) let us imagine a man who, while standing on the street, would say to himself:

"It is six o'clock in the evening, the working day is over. Now I can go for a walk, or I can go to the club; I can also climb up the tower to see the sunset; I can go to the theater; I can visit this friend or that one; indeed, I also can run out of the gate, into the wide world, and never return. All of this is strictly up to me, in this I have complete freedom. But still I shall do none of these things now , but with just as free a will I shall go home to my wife".

This is exactly as if water spoke to itself: "I can make high waves (yes! in the sea during a storm), I can rush down hill (yes! in the river bed), I can plunge down foaming and gushing (yes! in the waterfall), I can rise freely as a stream of water into the air (yes! in the fountain), I can, finally boil away and disappear (yes! at a certain temperature); but I am doing none of these things now, and am voluntaringly remaining quiet and clear water in the reflecting pond.

As the strata of the earth preserve in succession the living creatures of past epochs, so the shelves of libraries preserve in succession the errors of the past and their expositions, which like the former were very lively and made a great commotion in their own age but now stand petrified and stiff in a place where only the literary palaeontologist regards them.
