Verbal Behavior: Extended Edition. Chapter 12: The Autoclitic. Quote 31

… considering three examples: (a) Jones is ill, (b) Jones is not well, (c) “Jones is well” is false. Although all three of these responses may be emitted with respect to the same state of affairs so far as Jones is concerned, they are not instances of the same response, and only one of them, (b), contains an autoclitic. They differ in their momentary effects upon the listener (and indirectly upon the speaker) and also in the collateral circumstances which generate them. (p. 324)
