Information
Information is any entity or form that provides the answer to a question of some kind or resolves uncertainty. It is thus related to data and knowledge, as data represents values attributed to parameters, and knowledge signifies understanding of real things or abstract concepts. As it regards data, the information's existence is not necessarily coupled to an observer (it exists beyond an event horizon, for example), while in the case of knowledge, the information requires a cognitive observer.
Information
Knowledge is of two kinds. We know a subject ourselves, or we know where we can find information upon it.
Samuel Johnson, Boswell's Life of Johnson, 18th April 1775.
Information
The functionaries of every government have propensities to command at will the liberty and property of their constituents. There is no safe deposit for these but with the people themselves; nor can they be safe with them without information.
Thomas Jefferson, Letter to Colonel Charles Yancey (6 January 1816) ME 14:384.
Information
When action grows unprofitable, gather information; when information grows unprofitable, sleep.
Ursula K. Le Guin (b. 1929), American Science Fiction author. The Left Hand of Darkness, Ch. 3 (1969).
