Status: This quotation has not been found in any of the writings of Thomas Jefferson. It is also frequently attributed to W. W. Ziege, and while Ziege did write an article that appeared in Rosicrucian Digest in December 1945, "The Magic Word," in which he essentially makes the same point, he did not use these exact words. No other writings of his in which this quotation may have appeared have yet been located.
