Who said “A large volume of adventures may be grasped within this little span of life, by him who…”?

“Without adventure civilization is in full decay.”

“Man needs difficulties; they are necessary for health.”

“The test of an adventure is that when you're in the middle of it, you say to yourself, "Oh, now I've got myself into an awful mess; I wish I were sitting quietly at home." And the sign that something's wrong with you is when you sit quietly at home wishing you were out having lots of adventure.”

“Adventure is worthwhile.”

“Who dares nothing, need hope for nothing.”

“The history of a soldier's wound beguiles the pain of it.”

“The desire of knowledge, like the thirst of riches, increases ever with the acquisition of it.”

“Of all the cants which are canted in this canting world -- though the cant of hypocrites may be the worst -- the cant of criticism is the most tormenting!”

“I wish either my father or my mother, or indeed both of them, as they were in duty both equally bound to it, had minded what they were about when they begot me.”

“So long as a man rides his Hobby-Horse peaceably and quietly along the King's highway, and neither compels you or me to get up behind him -- pray, Sir, what have either you or I to do with it?”

“Men tire themselves in pursuit of rest.”
