Impulse and Novelty

Whitehead's observation that "imaginative zest is tinged with impulse" is perhaps an illusion to Dewey's concept of Impulse as the origin of Novelty.  But, regardless, there is a significant difference between the two concepts of Impulse.  Now, according to Dewey, Impulse initiates Action, whereas, in Whitehead's system, Impulse initiates a Teleological Mental event.  In other words, for Dewey, Novelty consists in changing the world, while for Whitehead, Novelty consists in re-interpreting the world.  Whitehead thus seems committed to the position that one can read a new book, but one cannot write a new book, or improvise musically.
