"The possible's slow fuse is lit by the imagination" ~ Emily Dickinson
"You can't depend on your eyes when your imagination is out of focus" ~ Mark Twain
"The eyes are not responsible when the mind does the seeing" ~ Publilius Syrus
"When patterns are broken, new worlds emerge" ~ Tuli Kupferberg
"It's not what you look at that matters, it's what you see" ~ Henry David Thoreau
"They who dream by day are cognizant of many things which escape those who dream only by night" ~ Edgar Allan Poe, "Eleonora"
Lastly, and somewhat more modestly amongst such great company:
"You perceive what you wish to perceive, there is no truth, perhaps no reality, it is for you to decide. Let your imagination be the key to your interpretation of realism. That is imaginism" ~ Thomas Hodges
