History
The phrase comes from Pliny the Elder's Naturalis Historia, regarding the discovery of a recipe for an antidote to a poison. In the antidote, one of the ingredients was a grain of salt. Threats involving the poison were thus to be taken "with a grain of salt," and therefore less seriously.
An alternative account says that the Roman general Pompey believed he could make himself immune to poison by ingesting small amounts of various poisons, and he took this treatment with a grain of salt to help him swallow the poison. In this version, the salt is not the antidote. It was taken merely to assist in swallowing the poison.
The Latin word salis means both "salt" and "wit," so that the Latin phrase "cum grano salis" could be translated as both "with a grain of salt" and "with a grain (small amount) of wit."
The phrase cum grano salis is not what Pliny wrote. It is constructed according to the grammar of modern European languages rather than Classical Latin. Pliny's actual words were addito salis grano.

Famous quotes containing the word history:
“Culture, the acquainting ourselves with the best that has been known and said in the world, and thus with the history of the human spirit.”
—Matthew Arnold (1822–1888)
“Philosophy of science without history of science is empty; history of science without philosophy of science is blind.”
—Imre Lakatos (1922–1974)
“No one can understand Paris and its history who does not understand that its fierceness is the balance and justification of its frivolity. It is called a city of pleasure; but it may also very specially be called a city of pain. The crown of roses is also a crown of thorns. Its people are too prone to hurt others, but quite ready also to hurt themselves. They are martyrs for religion, they are martyrs for irreligion; they are even martyrs for immorality.”
—Gilbert Keith Chesterton (1874–1936)
