No institution uses this rhetorical ploy more effectively than religion. The ancients believed in a three-layered world, but they also included the Four Corners, the four Cardinal Directions. When these are added to the three-tiered system we get a sevenfold system, as seen earlier in the octahedron. This septanary, coupled with the seven "planets", gave us the seven days of the week; and the Six Days Of Creation and the Seventh Day of Rest are held by Jewish mystics to represent this structure.²⁹ Nor is this symbol restricted to Judaism. The pyramids of the Egyptians and the Aztecs, as well as the ziggurats of the Mesopotamians, testify to their belief in an octrahedronal Universe. The table below shows many variations on this same theme, the main point being this: not a single word of this is true—it's all pure rhetoric. Still, the universal acceptance of this septanary model, as demonstrated by these several instances, aptly shows its value for Rhetoric.
