For Luhmann, the last elements in social systems are not men who act in them, but the communications that take place there. A social system is self-directed, consistently producing interconnected communications. Only social systems (interaction, organization, society) can communicate in contrast to the psychic systems (consciousness), who only think. Thus, the author advocates a radical concept of communication as a triple array of information, communication and understanding for which, he says, "has every blasphemy of the rowers in the galleys."
