historical usage of prove

The idiom “The exception proves the rule” comes direct from the Roman statesman, lawyer, orator, and man of letters Marcus Tullius Cicero (106-43 b.c.) in a speech he wrote and delivered, Pro Balbo, in 56 b.c., as defense counsel for Lucius Cornelius Balbo Major (“Senior”). The full Latin sentence is exceptiō probat rēgulam in cāsibus non exceptīs “The exception tests the rule in cases that are not excepted,” which makes clear the implied existence of a general rule: for example, “No parking on Saturdays and Sundays” implies that parking is allowed the other five days of the week. Most often, however, the amputated sentence “The exception proves the rule” allows the meaning to be “The exception validates the rule.”
