Famous quotes containing the words quantum, mutual and/or information:
“A personality is an indefinite quantum of traits which is subject to constant flux, change, and growth from the birth of the individual in the world to his death. A character, on the other hand, is a fixed and definite quantum of traits which, though it may be interpreted with slight differences from age to age and actor to actor, is nevertheless in its essentials forever fixed.”
—Hubert C. Heffner (1901–1985)
“Whoever takes a view of the life of man ... will find it so beset and hemm’d in with obligations of one kind or other, as to leave little room to suspect, that man can live to himself: and so closely has our creator link’d us together ... that we find this bond of mutual dependence ... is too strong to be broke.”
—Laurence Sterne (1713–1768)
“I believe it has been said that one copy of The Times contains more useful information than the whole of the historical works of Thucydides.”
—Richard Cobden (1804–1865)
