To reciprocate is to return good in proportion to the good one has received, or to retaliate proportionately for harms. The central, contested philosophical issues surrounding reciprocity are whether reciprocity is a fundamental moral principle or a subsidiary one; how we are to measure fittingness and proportionality; and whether the norm of reciprocity requires that we reciprocate for all the goods we receive, or only for the ones we invite. While most philosophers believe that reciprocity is a subsidiary principle which is unproblematic only in the context of fully voluntary transactions, there are significant minority views on this matter.
