The world in which we live falls short in terms of justice in many different ways. We have reason to do what we can to remove diagnosable injustice to the extent possible. Subjecting our values to scrutiny by asking probing questions, drawing on many sources, may be a good beginning. Broadening that exercise by considering the perspectives of others – from far as well as near – would make sense here, for reasons that Smith had discussed with much clarity a quarter of a millennium ago.
