A perfect man would never act from a sense of duty; he’d always want the right thing more than the wrong one. Duty is only a substitute for love (of God and of other people) like a crutch which is a substitute for a leg. Most of us need the crutch at times; but of course it is idiotic to use the crutch when our own legs (our own loves, tastes, habits etc.) can do the journey on their own.
C. S. LewisEducation without values, as useful as it is, seems rather to make man a more clever devil.
C. S. LewisThe great thing is to be found at one's post as a child of God, living each day as though it were our last, but planning as though the world might last a hundred years.
C. S. LewisI have received no assurance that anything we can do will eradicate suffering. I think the best results are obtained by people who work quietly away at limited objectives, such as the abolition of the slave trade, or prison reform, or factory acts, or tuberculosis, not by those who think they can achieve universal justice, or health, or peace. I think the art of life consists in tackling each immediate evil as well as we can.
