Abstract: To speak is to ascribe a certain intention to an utterance on the basis of affordance. Affordance is the possibilities that enable a human being to take a certain intentional action in context. Affordance is the perceived properties of an entity. It is neither the objective properties a thing possesses, nor is it the subjective qualities an agent has in his mind. It is something that bridges the objective facts and subjective mental experiences. The affordance in context makes it possible to ascribe an intention to an utterance. Like quale, affordance supervenes physical properties on the one hand, and it is independent of them on the other.
