Nauheim, June 19, 1910.
P. S. Another illustration of my meaning: The clock of the universe is running down, and by so doing makes the hands move. The energy absorbed by the hands and the mechanical work they do is the same day after day, no matter how far the weights have descended from the position they were originally wound up to. The history which the hands perpetrate has nothing to do with the quantity of this work, but follows the significance of the figures which they cover on the dial. If they move from O to XII, there is "progress," if from XII to O, there is "decay," etc. etc.

Constance, June 26, [1910].
Yours of the 20th, just arriving, pleases me by its docility of spirit and passive subjection to philosophic opinion. Never, never pretend to an opinion of your own! that way lies every annoyance and madness! You tempt me to offer you another illustration—that of the hydraulic ram (thrown back to me in an exam, as a "hydraulic goat" by an insufficiently intelligent student). Let this arrangement of metal, placed in the course of a brook, symbolize the machine of human life. It works, clap, clap, clap, day and night, so long as the brook runs at all, and no matter how full the brook (which symbolizes the descending cosmic energy) may be, it works always to the same effect, of raising so many kilogrammeters of water. What the value of this work as history may be, depends on the uses to which the water is put in the house which the ram serves.
