“When all is said, a man's final judgment of his fellows must be based upon his knowledge of himself”

“A man must sometimes laugh at himself or go mad,’ said he. ‘Few realize it. That is why there are so many madmen in the world.”

“Peter Blood judged her- as we are all prone to do- upon insufficient knowledge.”

“If Mr. Blood had condescended to debate the matter with these ladies, he might have urged that having had his fill of wandering and adventuring, he was now embarked upon the career for which he had been originally intended and for which his studies had equipped him; that he was a man of medicine and not of war; a healer, not a slayer.”

“He vowed that the thought of her should continue ever before him to help him keep his hands as clean as a man might in this desperate trade upon which he was embarking. And so, although he might entertain no delusive hope of ever winning her for his own, of ever seeing her again, yet the memory of her was to abide in his soul as a bitter-sweet, purifying influence. The love that is never to be realized will often remain a man’s guiding ideal.”

“In endeavor itself there is a certain dynamic entertainment, affording an illusion of useful purpose. With achievement the illusion is dispelled. Man's greatest accomplishment is to produce change. The only good in life is study, because study is an endeavor that never reaches fulfillment. It busies a man to the end of his days, and it aims at the only true reality in all this world of shams and deceits.”
