A state cannot tax, govern or trade land it cannot see, so it surveys, maps and registers. That delivers secure ownership, credit and markets, but writing land down means deciding what to leave out, often the overlapping rights that protected the powerless. The episode examines the cadastre, the Torrens system and James C. Scott's idea of legibility.
Credit for the Torrens system is split between its champion and its architect. Whether formal title delivers credit, whether a register can hold overlapping rights, and whether Scott is too pessimistic about legibility are all open.
