I was thinking about the last sentence in Middlemarch here;
for the growing good of the world is partly dependent on unhistoric acts; and that things are not so ill with you and me as they might have been, is half owing to the number who lived faithfully a hidden life, and rest in unvisited tombs."
and this sentence in Atlas Shrugged: "I swear by my life and my love it that I will never live for the sake of another man, nor ask another man to live for mine."
these sentences capture the essence of the two themes we see in our class, in my opinion?
Do you agree?
