Did you ever hear of a man who had striven all his life faithfully and singly towards an object, and in no measure obtained it? If a man constantly aspires, is he not elevated? Did ever a man try heroism, magnanimity, truth, sincerity, and find that there was no advantage in them,--that it was a vain endeavor?
