Things seen are mightier than things heard.

Our sight is the most perfect and most delightful of all our senses. It fills the mind with the largest variety of ideas, converses with its objects at the greatest distance, and continues the longest in action without being tired or satiated with its proper enjoyments.

The hunger of the eye is not to be despised; and they are to be pitied who have starvation of the eye.

When I walk with a camera, I walk from shot to shot, reading the light on a calibrated meter. When I walk without a camera, my own shutter opens, and the moment's light prints on my own silver gut. When I see this second way I am above all an unscrupulous observer.

The eye obeys exactly the action of the mind.

Eyes are more accurate witnesses than ears.

New ways of seeing can disclose new things: the radio telescope revealed quasars and pulsars, and the scanning electron microscope showed the whiskers of the dust mite. But turn the question around: Do new things make for new ways of seeing?
