"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 (1980).

"Seeing, as philosophers of science are quick to point out, is a theory-laden activity. What this means is that there is much more to vision than the image that falls on the back of your retinas. What you know and believe affects what you see. Your expectations and knowledge don’t just help you to understand and interpret what you see, they in part help you to construct and categorise what you see."
— Nigel Warburton in The Art Question
