 The descriptive meaning of a sign is a disposition that relates the sign to a range of “cognitive” states, including belief, supposition, presumption, etc. From a hearer or reader’s point of view, cognitive states are the responses, tokens of the sign are the stimuli. From a speaker or writer’s point of view, cognitive states are the stimuli, tokens of the sign are the responses. Cognitive states, like attitudes, are complex dispositions. (1944, 62–71)
