Famous quotes containing the word function:

    “The intension of a proposition comprises whatever the proposition entails: and it includes nothing else.... The connotation or intension of a function comprises all that attribution of this predicate to anything entails as also predicable to that thing.”
    —Clarence Lewis (1883–1964)
