“To recognize our bias toward error should teach us modesty and reflection, and to forgive it should help us avoid the inhumanity of thinking we ourselves are not as fallible as those who, in any instance, seem most at fault. Science can give us knowledge, but it cannot give us wisdom. Nor can religion, until it puts aside nonsense and distraction and becomes itself again.”

“History cannot give us a program for the future, but it can give us a fuller understanding of ourselves, and of our common humanity, so that we can better face the future.”

“Each one of us here today will at one time in our lives look upon a loved one who is in need and ask the same question: We are willing to help, Lord, but what, if anything, is needed? For it is true we can seldom help those closest to us. Either we don't know what part of ourselves to give or, more often than not, the part we have to give is not wanted. And so it is those we live with and should know who elude us. But we can still love them - we can love completely without complete understanding.”

“We should never wait for science to give us permission to do the uncommon; if we do, then we are turning science into another religion.”

“No, our science is no illusion. But an illusion it would be to suppose that what science cannot give us we can get elsewhere.”

“The history of philosophy, and perhaps especially of moral, social and political philosophy, is there to prevent us from becoming too readily bewitched. The intellectual historian can help us to appreciate how far the values embodied in our present way of life, and our present ways of thinking about those values, reflect a series of choices made at different times between different possible worlds. This awareness can help to liberate us from the grip of any one hegemonal account of those values and how they should be interpreted and understood. Equipped with a broader sense of possibility, we can stand back from the intellectual commitments we have inherited and ask ourselves in a new spirit of enquiry what we should think of them.”
