Is it possible to measure a people’s capacity for containing the ambitions of any regime at its helm—its ability to resist the power of a tyrant? We begin here from the premise that this power has to be in proportion to individuals’ capacity (both individually and in groups) for communicating, at least among themselves, dissatisfaction with the regime. As the paper subsequently shows, by articulating an ontology of information diffusion on a communication network structure, it is possible to take some (...) stock of the features of a communications network that facilitate resistance to tyranny (among other things), and so to begin answering questions about the sort of power that people living within them might be able to mobilize, while not yet answering outright the question of how to measure the power to resist.
