Sociology is the science of social life, and as such, it is different from the pursuit of social justice and other efforts to evaluate or to reform the social world. Still, the idea of social justice is intimately connected with the idea of sociology. It arises along with scientific understandings of the social world and draws from these understandings to reshape society. The problem is that in practice, social justice activists often draw from only one type of sociological theory, conflict theory, and from a particular form of conflict theory known as critical theory. In doing so, they may ignore potential problems with the theories they are drawing from, and they may overlook many possibilities for effective reform. Conflict theory orients activists toward fighting oppression, but other theoretical approaches could help societies to achieve other possible moral goals, such as promoting understanding, increasing virtue, incentivizing virtue, making virtue easier, and strengthening solidarity.
