Four maps of how people, in groups, actually behave across history — read not side by side, but as strata.
Watch human beings over three thousand years and the same fractures keep opening. Each one can be peeled downward: the numbers on the surface, the reasons beneath them, the statecraft beneath the reasons, and the myth at the root where the pattern was first told. The four maps are those four depths. Pick a fracture below and fall through it — or enter any single map directly.
