Shepherds don't look after sheep because they love them - although I do think some shepherds like their sheep too much. They look after their sheep so they can, first, fleece them and second, turn them into meat. That's much more like the priesthood as I know it. - Christopher Hitchens

But I don`t have to know an answer. I don`t feel frightened by not knowing things, by being lost in the mysterious universe without having any purpose — which is the way it really is, as far as I can tell, possibly. It doesn`t frighten me. - Richard Feynman
