How can we justify partiality to those near to us, such as our own families, friends, neighbours and colleagues, when we could act in much more morally valuable ways by helping others who are merely distant from us? In 1972 Peter Singer used two now-famous examples, Pond and Overseas, to challenge our complacent partiality. The charge of neglect of an obvious moral duty to meet distant grave needs is refined and developed by Peter Unger(1996).
Although Singer is a consequentialist, he intends the problem of distance to challenge all moral thinkers irrespective of their theoretical commitments. Singer's challenge has somehow to be met, and this is what discussions of the problem of distance in contemporary analytic philosophy attempt to do. To solve the problem, we have to reject
or modify impartialism or partialism.
