In future urban communities, a new paradigm is needed in which all citizens can participate in community formation as active members and practical beings of the community. This paper discusses an active humanistic approach to multiculturalism as a way to increase social capacity. To overcome disasters and crises, this paper conducts discussions on the foundation of Humanities and the literacy capabilities to change the paradigm of creating a local community based on solidarity across nationalities and races. In order to enter an era in which all community members fulfill their roles and responsibilities as citizens, literacy skills are required as a communicator of humanities and community connection. This thesis attempts a more comprehensive and objective reflection on our society as a prerequisite for developing literacy capabilities in a post-multicultural society. This thesis discusses the dangers of discrimination and exclusion inherent in advanced technology development and convenience. Instead of sympathy and tolerance toward strangers, discrimination and exclusion, that is, humanistic foundations such as the ethics of hospitality, are important factors for enhancing the literacy capacity of the community. We propose a ‘Communicator’ who can learn the humanities aimed by the community and lead a complete fusion between community and community, and between individual and individual. Communicators are universal citizens who can form and operate communities, and communicators with humanistic literacy capabilities are necessary citizens in a post-multicultural society.
