In modern western culture, we usually think of ourselves as autonomous, self-defined individuals. When multiple individuals create connections between them, community is formed.
A different perspective to try on is to consider that the individual can only occur in the context of community. Who a person 'is' is given by how they are seen and experienced in their community, rather than by how they see themselves. Community is the context in which individuals exist, and it is the community's collective responsibility to support each individual in developing their excellence, their virtue, their arete.
We create community to support one another, to reflect one another, and to create a life greater than any of us could alone. Community is the vehicle we use for greater openness, yet it is an inherently valuable and beautiful thing on its own.
