" not because the moral law enjoins unselfishness, but because, given the society in which they live, it is the way in which their impulses and desires prompt them to act. It is clear that better institutions, better education of the emotions, and a better apportioning of praise and blame, would increase the already considerable extent to which people’s actions further the well-being of their community. It is to such causes, rather than to a revived belief in supernatural sanctions, that we must look for ethical progress. "

― Bertrand Russell , Human Society in Ethics and Politics
