John Philpot Curran (17501817)
It is the common fate of the indolent to see their rights become a prey to the active. The condition upon which God hath given liberty to man is eternal vigilance; which condition if he break, servitude is at once the consequence of his crime and the punishment of his guilt.

An early use of the words eternal vigilance. Bartletts Familiar Quotations, at least, lists this as the source of eternal vigilance is the price of liberty (15th ed., p. 397, footnote 8, 1980). But see also No. 1073.
