Karl Karnadi

“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 something like that happened in politics or religion.”
― Carl Sagan

“Science is a way of thinking much more than it is a body of knowledge.”
― Carl Sagan

“The nitrogen in our DNA, the calcium in our teeth, the iron in our blood, the carbon in our apple pies were made in the interiors of collapsing stars. We are made of starstuff.”
― Carl Sagan, Cosmos

“If what you seek is Truth, there is one thing you must have above all else.” “I know. An overwhelming passion for it.” “No. An unremitting readiness to admit you may be wrong.”
― Anthony de Mello
