One forms provisional theories and waits for time or fuller knowledge to explode them. A bad habit, Mr. Ferguson, but human nature is weak. Sherlock Holmes speaking with Dr. Watson.

The mystic chords of memory, stretching from every battle-field, and patriot grave, to every living heart and hearth-stone, all over this broad land, will yet swell the chorus of the Union, when again touched, as surely they will be, by the better angels of our nature. --as quoted in THE RIVER OF WINGED DREAMS

The result of his error was the French Revolution. It was an admirable result.
