Solidarity and Prosocial Behavior

The topic of prosocial behavior (e.g. fairness, solidarity, and altruism) has recently shifted back into the center of attention in a variety of disciplines, ranging from economics across sociology and psychology towards biology. It is now a well-accepted fact in all human sciences that human behavior is not always governed by egotism and selfish motives. Unfortunately, this does not explain why human also act blatantly selfish and are blind to the suffering of others.
