Diogenes of Sinope
What we owe one another in the global context is one of the questions the global justice concept seeks to answer. There are positive and negative duties which may be in conflict with ones moral rules. Cosmopolitans, reportedly including the ancient Greek Diogenes of Sinope, have described themselves as "citizens of the world". William Godwin ( Utilitarian thinker and anarchist) argued that everyone has an impartial duty to do the most good he or she can, without preference for any one human being over another.
