Famous quotes containing the word exception:
“The Jew is neither a newcomer nor an alien in this country or on this continent; his Americanism is as original and ancient as that of any race or people with the exception of the American Indian and other aborigines. He came in the caravels of Columbus, and he knocked at the gates of New Amsterdam only thirty-five years after the Pilgrim Fathers stepped ashore on Plymouth Rock.”
—Oscar Solomon Straus (1850–1926)
“There are those who would build the Temple,
And those who prefer that the Temple should not be built.
In the days of Nehemiah the Prophet
There was no exception to the general rule.”
—T.S. (Thomas Stearns)
“The ways by which you may get money almost without exception lead downward. To have done anything by which you earned money merely is to have been truly idle or worse.”
—Henry David Thoreau (1817–1862)
