"Concerning the materials of seditions. It is a thing well to be considered; for the surest way to prevent seditions (if the times do bear it) is to take away the matter of them. For if there be fuel prepared, it is hard to tell, whence the spark shall come, that shall set it on fire. The matter of seditions is of two kinds: much poverty, and much discontentment. It is certain, so many overthrown estates, so many votes for troubles. Lucan noteth well the state of Rome before the Civil War: Hinc usura vorax, rapidumque in tempore foenus, Hinc concussa fides, et multis utile bellum."
