At one time there were found certain stones covered with wedge- formed grooves; it was a long time before men discovered that these grooves have a meaning and were in ancient times the writing of a cultured people, the “cuneiformwriting” of the Assyrians. This discovery comprehends two facts: first, that it is possible to add a system of rules to the grooves pn the stones in such a way that they enter into relations with facts of the kind occurring in human history; second, that these rules were used by the Assyrians and that the grooves were produced by them. This second discovery is of great importance to history, but to logic the first discovery is the important one. To confer the name of symbols upon certain physical entities it is sufficient that rules can be added to them in such a way that correspondence to facts arises; it is not necessary that the
