… is from No. 62 of Cato’s Letters – this one by Thomas Gordon and first published on January 20th, 1722:
It is a mistaken notion in government, that the interest of the majority is only to be consulted, since in society every man has a right to every man’s assistance in the enjoyment and defence of his private property; otherwise the greater number may sell the lesser, and divide their estates amongst themselves; and so, instead of a society, where all peaceable men are protected, become a conspiracy of the many against the minority. With as much equity may one man wantonly dispose of all, and violence may be sanctified by mere power.
