"...nobody knows what art is or God or all the other abstractions, particularly those who make claims to such knowledge.  There are a few, however, who do know what photography is... they have some idea whether a thing is genuine and alive or false or dead.

"In closing, I will say this to you as students of photography.  Don't think when I say students that I am trying to talk down.  We are all students.  Some a little longer at it than the others, a little more experienced.  When you cease to be a student you might as well be dead as far as the significance of your work is concerned... if this camera machine with its materials fascinates you, compels your energy and respect, learn to photograph.  Find out first what this machine and these materials can do without any interference except your own vision." ~ Paul Strand from The Art Motive in Photography 1923
