Making sense involves three kinds of action: representing, communicating and interpreting. These are not merely things of the mind or sign systems. They are kinds of social participation. They also require work. They use material tools and media for their work, as is the habit of our species, otherwise known as homo faber. They are things you do to mean, and the things you need to use in that meaning, in the context of shared social conditions. Participation is the making of meaning in the context of the social relations of its sharing—whether it is representation (making meanings for oneself); communication (making meanings that are accessible to others); or interpretation (making sense of meanings in the found objects of multimodal communication).
