    Poor John Field!—I trust he does not read this, unless he will improve by it,—thinking to live by some derivative old-country mode in this primitive new country.... With his horizon all his own, yet he a poor man, born to be poor, with his inherited Irish poverty or poor life, his Adam’s grandmother and boggy ways, not to rise in this world, he nor his posterity, till their wading webbed bog-trotting feet get talaria to their heels.
    Henry David Thoreau (1817–1862)

    Evil can be got very easily and exists in quantity: the road to her is very smooth, and she lives near by. But between us and virtue the gods have placed the sweat of our brows; the road to her is long and steep, and it is rough at first; but when a man has reached the top, then she is easy to attain, although before she was hard.
    Hesiod (c. 8th century B.C.)
