“And what, O Queen, are those things that are dear to a man? Are they not bubbles? Is not ambition but an endless ladder by which no height is ever climbed till the last unreachable rung is mounted? For height leads on to height, and there is not resting-place among them, and rung doth grow upon rung, and there is no limit to the number.”

“However, for the man who studies to gain insight, books and studies are merely rungs of the ladder on which he climbs to the summit of knowledge. As soon as a rung has raised him up one step, he leaves it behind. On the other hand, the many who study in order to fill their memory do not use the rungs of the ladder for climbing, but take them off and load themselves with them to take away, rejoicing at the increasing weight of the burden. They remain below forever, because they bear what should have bourne them.”

“Fate is a ladder on which you cannot afford to miss a single rung. To skip out on even one step would mean you'll never make it to the top.”

“Cruelty to animals is an enormous injustice; so is expecting those on the lowest rung of the economic ladder to do the dangerous, soul-numbing work of slaughtering sentient beings on our behalf.”

“Every author really wants to have letters printed in the paper. Unable to make the grade, he drops down a rung of the ladder and writes novels.”
