"The way to find out about our place in the universe is by examining the universe and by examining ourselves - without preconceptions, with as unbiased a mind as we can muster."
"The nuclear arms race is like two sworn enemies standing waist deep in gasoline, one with three matches, the other with five."
"We've arranged a civilization in which most crucial elements profoundly depend on science and technology. We have also arranged things so that almost no one understands science and technology. This is a prescription for disaster."
"The cosmos is within us. We are made of star-stuff. We are a way for the universe to know itself."
