“What is love except another name for the use of positive reinforcement? Or vice versa.”

“We can achieve a sort of control under which the controlled, though they are following a code much more scrupulously than was ever the case under the old system, nevertheless feel free. They are doing what they want to do, not what they are forced to do. That's the source of the tremendous power of positive reinforcement-- there's no restraint and no revolt. By careful cultural design, we control not the final behavior, but the inclination to behave-- the motives, desires, the wishes.”

“...not everyone is willing to defend a position of 'not knowing.' There is no virtue in ignorance for its own sake.”

“Why did colleges make their students take examinations, and why did they give grade? What did a grade really mean? When a student "studied" did he do anything more than read and think-- or was there something special which no one in Walden Two would know about? Why did the professors lecture to the students? Were the students never expected to do anything except answer questions? Was it true that students were made to read books they were not interested in?”

“Promising paradise or threatening hell-fire is, we assumed, generally admitted to be unproductive. It is based upon a fundamental fraud which, when discovered, turns the individual against society and nourishes the very thing it tries to stamp out. What Jesus offered in return of loving one's enemies was heaven on earth, better known as peace of mind.”

“In a world of complete economic equality, you get and keep the affections you deserve. You can’t buy love with gifts or favors, you can’t hold love by raising an inadequate child, and you can’t be secure in love by serving as a good scrub woman or a good provider.”

“Education is what survives when what has been learnt has been forgotten.”
