Science doesn't always go forwards. It's a bit like doing a Rubik's cube. You sometimes have to make more of a mess with a Rubik's cube before you can get it to go right. You build up this picture of what there is and you believe it to be true and you work with this picture and you refine it but sometimes you have to abandon the picture. Sometimes you discover the picture you thought you had, that everybody thought we had, actually turns out to be wrong.

But when you come right down to it the reason that we did this job is because it was an organic necessity. If you are a scientist you cannot stop such a thing. If you are a scientist you believe that it is good to find out how the world works; that it is good to find out what the realities are; that it is good to turn over to mankind at large the greatest possible power to control the world and to deal with it according to its lights and its values.
Robert Oppenheimer
Wanted or unwanted, I believe that human life, even at its earliest stages, has certain rights which must be recognized – the right to be born, the right to love, the right to grow old.... When history looks back to this era it should recognize this generation as one which cared about human beings enough to halt the practice of war, to provide a decent living for every family, and to fulfill its responsibility to its children from the very moment of conception.

Such is the common process of marriage. A youth and maiden meeting by chance, or brought together by artifice, exchange glances, reciprocate civilities, go home, and dream of one another. Having little to divert attention, or diversify thought, they find themselves uneasy when they are apart, and therefore conclude that they shall be happy together. They marry, and discover what nothing but voluntary blindness had before concealed; they wear out life in altercations, and charge nature with cruelty.
Samuel Johnson
In science it often happens that scientists say, 'You know that's a really good argument; my position is mistaken,' and then they would actually change their minds and you never hear that old view from them again. They really do it. It doesn't happen as often as it should, because scientists are human and change is sometimes painful. But it happens every day. I cannot recall the last time someting like that happened in politics or religion.
Carl Sagan
If violence is wrong in America, violence is wrong abroad. If it is wrong to be violent defending black women and black children and black babies and black men, then it is wrong for America to draft us, and make us violent abroad in defense of her. And if it is right for America to draft us, and teach us how to be violent in defense of her, then it is right for you and me to do whatever is necessary to defend our own people right here in this country.
