George Bernard Shaw

Progress is impossible without change, and those who cannot change their minds cannot change anything.

It is a curious sensation: the sort of pain that goes mercifully beyond our powers of feeling. When your heart is broken, your boats are burned: nothing matters any more. It is the end of happiness and the beginning of peace.

The reasonable man adapts himself to the world; the unreasonable man persists in trying to adapt the world to himself. Therefore, all progress depends on the unreasonable man.

Some men see things as they are and say, ''Why?'' I of dream things that never were, and say, ''Why not?''

It is all that the young can do for the old, to shock them and keep them up to date.

We are all dependent on one another, every soul of us on earth.

Life is no brief candle to me. It is a sort of splendid torch which I have got a hold of for the moment, and I want to make it burn as brightly as possible before handing it on to future generations.

We are made wise not by the recollection of our past, but by the responsibility for our future.

The only service a friend can really render is to keep up your courage by holding up to you a mirror in which you can see a noble image of yourself.

The liar's punishment is not in the least that he is not believed, but that he cannot believe anyone else.
