'Wilberforce's pursuit of a broad and uplifting vision of society elevates him far above the general rank of politicians. But the fact that he managed to live according to his own principles, and constantly reflect his own beliefs in his own character, is his crowning glory. It may be easier to disdain money and give much of it away if you inherit a large amout of it, but few people born in that position actually do so. It is easy to think that a Member of Parliament can resist all temptations of seeking high office if he has a great cause as an alternative, but it is still a rare event. Wilberforce exercised a genuine and remarkable self-discipline, and managed to do so while maintaining an optimistic and vivacious disposition. His conduct as a husband, father or elected representative is hard to fault. His generosity to those who came to him in need of help became an outstanding example of the virtues he called for in others. He showed how a political career can be conducted differently, pursuing long-term objectives deeply rooted in certain principles, strengthened in his indifference to holding power by his understanding of its transitory nature. As a result, he defied the axiom that political careers necessarily end in failure, going to the grave fulfilled by the knowledge of what he had helped to do, while those politicians to whom power alone is important decline in their old age into bitterness and despair.'
