“The whole modern world has divided itself into Conservatives and Progressives. The business of Progressives is to go on making mistakes. The business of Conservatives is to prevent mistakes from being corrected. Even when the revolutionist might himself repent of his revolution, the traditionalist is already defending it as part of his tradition. Thus we have two great types -- the advanced person who rushes us into ruin, and the retrospective person who admires the ruins. He admires them especially by moonlight, not to say moonshine. Each new blunder of the progressive or prig becomes instantly a legend of immemorial antiquity for the snob. This is called the balance, or mutual check, in our Constitution.”

“A person who makes few mistakes makes little progress.”

“There’s this thing called progress. But it doesn’t progress, it doesn’t go anywhere. Because as progress progresses the world can slip away. It’s progress if you can stop the world slipping away. My humble model for progress is the reclamation of land. Which is repeatedly, never-endingly retrieving what is lost. A dogged, vigilant business. A dull yet valuable business. A hard, inglorious business. But you shouldn’t go mistaking the reclamation of land for the building of empires.”

“We all want progress. But progress means getting nearer to the place where you want to be. And if you have taken a wrong turning then to go forward does not get you any nearer. If you are on the wrong road progress means doing an about-turn and walking back to the right road and in that case the man who turns back soonest is the most progressive man. There is nothing progressive about being pig-headed and refusing to admit a mistake. And I think if you look at the present state of the world it's pretty plain that humanity has been making some big mistake. We're on the wrong road. And if that is so we must go back. Going back is the quickest way on.”

“It is true that a man (a silly man) might make change itself his object or ideal. But as an ideal, change itself becomes unchangeable. If the change-worshipper wishes to estimate his own progress, he must be sternly loyal to the ideal of change; he must not begin to flirt gaily with the ideal of monotony. Progress itself cannot progress”

“People who make no mistakes lack boldness and the spirit of adventure. They are the brakes on the wheels of progress.”
