Sigmund Freud and William Bullitt (who worked closely with Woodrow WIlson at the Versailles conference) wrote a book titled Woodrow Wilson: A Psychological Study. Excerpt:
Throughout his life he took intense interest only in subjects which could somehow be connected with speech…He took no interest in mathematics, science, art or music–except in singing himself, a form of speaking. His method of thinking about a subject seems to have been to imagine himself making a speech about it…He seems to have thought about political or economic problems only when he was preparing to make a speech about them either on paper or from the rostrum. His memory was undoubtedly of the vaso-motor type. The use of his vocal chords was to him inseparable from thinking.
