"It is far better to grasp the universe as it really is than to persist in delusion, however satisfying and reassuring."
"One of the saddest lessons of history is this: If we’ve been bamboozled long enough, we tend to reject any evidence of the bamboozle. We’re no longer interested in finding out the truth.

"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."
"Imagination will often carry us to worlds that never were. But without it we go nowhere."
"I don't want to believe. I want to know."
