John Rawls said this quote

Many of our most serious conflicts are conflicts within ourselves. Those who suppose their judgements are always consistent are unreflective or dogmatic.

~ John Rawls

Justice is the first virtue of social institutions, as truth is of systems of thought. A theory however elegant and economical must be rejected or revised if it is untrue; likewise laws and institutions no matter how efficient and well-arranged must be reformed or abolished if they are unjust. Each person possesses an inviolability founded on justice that even the welfare of society as a whole cannot override. For this reason justice denies that the loss of freedom for some is made right by a greater good shared by others. It does not allow that the sacrifices imposed on a few are outweighed by the larger sum of advantages enjoyed by many. Therefore in a just society the liberties of equal citizenship are taken as settled; the rights secured by justice are not subject to political bargaining or to the calculus of social interests.

~ John Rawls

Thus I assume that to each according to his threat advantage is not a conception of justice.

~ John Rawls

The refusal to take part in all war under any conditions is an unworldly view bound to remain a sectarian doctrine. It no more challenges the state's authority than the celibacy of priests challenges the sanctity of marriage.
