But if in the process we learn how to achieve it by love rather than by fear, by kindness rather than compulsion; if in the process we learn how to combine the essential with the enjoyable, the expedient with the benevolent, the practical with the beautiful, this will be an extra incentive to embark on this great task. Above all, remember your humanity. -- Sir Joseph Rotblat
