  Quotations
  We should so organize our rank and mobilize our forces that our influence may not be dissipated before the advancing hosts of quackery and ignorance. This we can do effectively if only the wise and successful ones among our leaders can be induced to forgo the dolce far niente of the noontime of their lives.
