ABSTRACT
This chapter states that solidarity is cooperation aimed at achieving the same goals and based on companionship and mutual goodwill. Solidarity does not preclude the existence of different classes within a society, but it assumes their complementarity, autonomy, and cooperation, instead of their struggle. Solidarity is destroyed by selfishness and quarrels, and rebuilt by a sense of common identity. Its opposite is enmity and the mechanization of human-kind based on coercion. Solidarity is based on individuals and institutions joined by bonds of cooperation, the most fundamental institution among these being the family. The widest range of solidarity is global solidarity. It is expressed in the cooperation of people from around the world. The natural tendency of human beings that follows from their social character is to cooperate. Moral corruption and cultural and civilizational differences among people hinder cooperation and change brotherhood into enmity. There is no liberty without solidarity; there is no solidarity without nobility.
