“We have a social responsibility, a constitutional opportunity and a moral obligation to help others.”

“We can't have moral obligations to every single person in this world. We have moral obligations to those who we come up against, who enter into our moral space, so to speak. That means neighbors, people we deal with, and so on.”

“I believe that every right implies a responsibility; every opportunity, an obligation; every possession, a duty.”

“We have no government armed with power capable of contending with human passions unbridled by morality and religion. Avarice, ambition, revenge or gallantry would break the strongest cords of our Constitution as a whale goes through a net. Our Constitution is designed only for a moral and religious people. It is wholly inadequate for any other.”

“Even as rigorous a determinist as Karl Marx, who at times described the social behaviour of the bourgeoisie in terms which suggested a problem in social physics, could subject it at other times to a withering scorn which only the presupposition of moral responsibility could justify.”

“We know too much, and what might have been excused in other times can no longer stand up to reason. ... with that understanding comes moral responsibility.”
