the argument to give some answer, so I began:--

"But if you don't like the life of a mill-horse, why do you lead it?"

"Why? because I have to!" he replied; "you don't suppose I would do it
if I could help it?"

"No," I said, "but why can't you help it?"

"Because," he said, "I have to earn my living."

"Then is it a good thing to earn your living?"

"No, but it's a necessary thing."

"Necessary, why?"

"Because one must live."

"Then it is a good thing to live?"

"No, it's a very bad one."

"Why do you live, then?"

"Because I can't help it."

"But it is always possible to stop living."

"No, it isn't"
