“In religion and politics people’s beliefs and convictions are in almost every case gotten at second-hand, and without examination, from authorities who have not themselves examined the questions at issue but have taken them at second-hand from other non-examiners, whose opinions about them were not worth a brass farthing.”

“Just remember: other people’s opinions are simply that—other people’s opinions. They are not fact, and they are certainly not “the truth.” It is your responsibility to question the authority you give others, to question opinions they want you to adopt as your own, and to question how it is they are observing the world themselves that has them seeing things as they do. Sometimes you need to take back the authority you are giving to the opinions of others and place a bit more trust in yourself.”

He imagined that the clock’s second hand possessed awareness and knew that it was a second hand and that its job was to go around and around inside a circle of numbers forever at the same slow, unvarying machinelike rate, going no place it hadn’t already been a million times before, and imagining the second hand was so awful it made his breath catch in his throat, and he looked quickly around to see if any of the examiners near him had heard it or were looking at him.”
