“What was the self-sacrifice?"I jettisoned half of a much-loved and I think irreplaceable pair of shoes."Why was that self-sacrifice?"Because they were mine!" said Ford, crossly.I think we have different value systems."Well mine's better.”

“So this is it," said Arthur, "We are going to die.""Yes," said Ford, "except... no! Wait a minute!" He suddenly lunged across the chamber at something behind Arthur's line of vision. "What's this switch?" he cried."What? Where?" cried Arthur, twisting round."No, I was only fooling," said Ford, "we are going to die after all.”

“Good,” said Arthur.“See?” said Ford.“No,” said Arthur.”

“We are different because our brain is wired differently. This causes us to perceive the world in different ways and have different values and priorities. Not better or worse - different.”
