"My own state of New York has given men like Theodore Roosevelt, Henry Stimson, Elihu Root, Charles Evan Hughes, and Thomas Dewey. These were men whose credos as 'progressive conservatives,' to use Stimson's own description, were built on their conviction, first, that the primary and overriding requirement of all government is that it should not infringe upon the essential liberties of the individual, and, second, that within this limitation government could and must be made a powerful instrument for the enhancement of individual citizens by group action."
