In this article, “We-mode theory” is discussed from the viewpoint of social cognition. Furthermore, the mental conditions that should be observed in the relationship between We-mode and non-humans, not humans, will also be examined. Ideas of how a deep understanding of others should be created will be introduced, based on the theory of interactionism seen in social cognition. The possibility of human and non-human coexistence should also be illustrated; i.e., the possibility of coexistence between the human-like robot “Astro Boy” and the disc-shaped vacuum cleaner robot “Roomba”.
