 Solidarity rules out the aggregative view. Starting with an appropriate view of her own interests, solidarity requires each citizen to give certain interests of her fellow citizens a status in her reasoning that is similar to the status that she gives to her own interests. This way of thinking does not allow citizens to abandon the interests of any of their fellow citizens for the sake of aggregate gains. For instance, solidarity would not allow citizens to subject some of their fellow citizens to slavery, even if this might produce substantial benefits for others, because enslavement would involve a failure on the part of each citizen to give the interests of each of her enslaved comrades the right status in her reasoning.
