Society needs both justice and compassion, a head and a heart, if it is to be civilised.

No genuine choice is ever simply a matter of the arbitrary exercise of will. Take your choice of lunch today. You can't decide to want anything, but what you want will at least in part be a result of a series of other choices and judgments you've made in your life to date.

Constructive complaint requires only two things: that what you are complaining about should be different, and that it can be different. It sounds simple, but too often our protests fail this test.

This is the deal: we are happy to single out people as superior just as long as they don't accept the description themselves. We want heroes and idols but we also want egalitarianism and that requires proclamations of humility from our Gods.

Rules matter, and to be rules they need to be universal in form: always do this, never do that. But it is foolish to rule out in advance the possibility that an occasion might arise when normal rules just don't apply. Rules are not there to be broken, but sometimes break them we must.

I maintain the importance of an absolute prohibition against torture, while acknowledging that even absolute prohibitions can sometimes be broken. If that is a contradiction, it is a contradiction that ethics has to embrace, or else it becomes like glass: hard, clear, but fatally inflexible.

Being virtuous is wonderful thing, but feeling virtuous is a shortcut to vice.
