“Perceptions trained in another climate and another landscape have had to be modified. That means we have had to learn to quit depending on perceptual habit. Our first and hardest adaptation was to learn all over again how to see. Our second was to learn to like the new forms and colors and light and scale when we had learned to see them. Our third was to develop new techniques, a new palette, to communicate them. And our fourth, unfortunately out of of our control, was to train an audience that would respond to what we wrote or painted.”

“We learn to endure to the end by learning to finish our current responsibilities, and we simply continue doing it all of our lives. We cannot expect to learn endurance in our later years if we have developed the habit of quitting when things get difficult now.”

“Human beings have always been an unfinished species, a story in the middle, a succession of families, tribes, and societies in transition to new awarenesses. Although we have always prided ourselves on our willingness to adapt to all habitats, and on our skill at prospering and making ourselves comfortable wherever we are -- in a meadow, in a desert, on the tundra, or out on the ocean -- we don't just adapt to places, or modify them in order to ease our burdens. We're the only species that over and over again has deliberately transformed our surroundings in order to stretch our capacity for understanding and provoke new accomplishments. And our growing and enhanced understanding is our most valuable, and our most vulnerable, inheritance.”

“Our part in life is to persevere and learn as quickly as we can, for our victory depends upon our perception of the world".”

“Learning requires a large dose if humility to offset our built-in arrogance, which is usually supported by deafness and massive ignorance. New knowledge can prompt us to modify our beliefs. If we want to stick to our prior convictions, we should avoid new information like the plague and close our minds to everything but the opinions that square with our own. This is the way of censors and bookburners.”

“We are men and our lot in life is to learn and to be hurled into inconceivable new worlds.”
