“In other studies you go as far as other have gone before you, and there is nothing more to know; but in a scientific pursuit there is continual food for discovery and wonder.”

“I do know that for the sympathy of one living being, I would make peace with all. I have love in me the likes of which you can scarcely imagine and rage the likes of which you would not believe. If I cannot satisfy the one, I will indulge the other.”

“Shall each man," cried he, "find a wife for his bosom, and each beast have his mate, and I be alone? I had feelings of affection, and they were requited by detestation and scorn. Man! You may hate, but beware! Your hours will pass in dread and misery, and soon the bolt will fall which must ravish from you your happiness forever. Are you to be happy while I grovel in the intensity of my wretchedness? You can blast my other passions, but revenge remains—revenge, henceforth dearer than light or food!

“Oh! Be men, or be more than men. Be steady to your purposes and firm as a rock. This ice is not made of such stuff as your hearts may be; it is mutable and cannot withstand you if you say that it shall not. Do not return to your families with the stigma of disgrace marked on your brows. Return as heroes who have fought and conquered, and who know not what it is to turn their backs on the foe.”
