[The moralist] believes…that nothing but an extension of social intelligence and an increase in moral goodwill can offer society a permanent solution for it social problems. Yet the moralist may be as dangerous a guide as the political realist. He usually fails to recognize the elements of injustice and coercion which as present in any contemporary social peace…A too uncritical glorification of co-operation and mutuality therefore results in the acceptance of traditional injustices and the preference of the subtler types of coercion to the more overt types.
Reinhold Niebuhr, Moral Man and Immoral Society, 233.
