“An action, to have moral worth, must be done from duty.”

“Moral conduct,or duty,is defined as the obligation to select that action which will achieve more good than any alternative action....”

“But you're the hardest thing I've ever done, and you're also the best. So... I think that's the moral of the story here. Anything worth having is worth fighting for.”

“If throughout your life you abstain from murder, theft, fornication, perjury, blasphemy, and disrespect toward your parents, church, and your king, you are conventionally held to deserve moral admiration even if you have never done a single kind, generous or useful action. This very inadequate notion of virtue is an outcome of taboo morality, and has done untold harm.”

“Realism maintains that universal moral principles cannot be applied to the actions of states in their abstract universal formulation, but that they must be filtered through the concrete circumstances of time and place. The individual may say for himself: "Fiat justitia, pereat mundus (Let justice be done, even if the world perish)," but the state has no right to say so in the name of those who are in its care. Both individual and state must judge political action by universal moral principles, such as that of liberty. Yet while the individual has a moral right to sacrifice himself in defense of such a moral principle, the state has no right to let its moral disapprobation of the infringement of liberty get in the way of successful political action, itself inspired by the moral principle of national survival.”

“The commitment to morality, or non-harming, is a source of tremendous strength, because it helps free the mind from the remorse of having done unwholesome actions. Freedom from remorse leads to happiness. Happiness leads to concentration. Concentration brings wisdom. And wisdom is the source of peace and freedom in our lives.”
