We should, I believe, beware of the pitfalls described by Taine: 'Imagine a man who sets out on a voyage equipped with a pair of spectacles that magnify things to an extraordinary degree. A hair on his hand, a spot on the tablecloth, the shifting fold of a coat, all will attract his attention; at this rate, he will not go far, he will spend his day taking six steps and will never get out of his room.' We have to get out of this room.

It is immoral to see evil and not act on it.

It is the essence of responsibility to put the public good ahead of personal gain

Every time we turn our heads the other way when we see the law flouted, when we tolerate what we know to be wrong, when we close our eyes and ears to the corrupt because we are too busy or too frightened, when we fail to speak up and speak out, we strike a blow against freedom and decency and justice.

I believe that, as long as there is plenty, poverty is evil.

Each nation has different obstacles and different goals, shaped by the vagaries of history and of experience. Yet as I talk to young people around the world I am impressed not by the diversity but by the closeness of their goals, their desires and their concerns and their hope for the future.
