Famous quotes containing the words large and/or systems:
“It is hard living down the tempers we are born with. We
all begin well, for in our youth there is nothing we
are more intolerant of than our own sins writ large in
others and we fight them fiercely in ourselves; but we
grow old and we see that these our sins are of all sins
the really harmless ones to own, nay that they give a
charm to any character, and so our struggle with them
dies away.”
—Gertrude Stein (1874–1946)
“What avails it that you are a Christian, if you are not purer than the heathen, if you deny yourself no more, if you are not more religious? I know of many systems of religion esteemed heathenish whose precepts fill the reader with shame, and provoke him to new endeavors, though it be to the performance of rites merely.”
—Henry David Thoreau (1817–1862)
