Often misattributed to Mozart as:
"Neither a lofty degree of intelligence nor imagination nor both together go to the making of genius. Love, love, love, that is the soul of genius."
-- Wolfgang Amadeus Mozart
"True genius without heart is a thing of nought - for not great understanding alone, not intelligence alone, nor both together, make genius. Love! Love! Love! that is the soul of genius."
-- Nikolaus Joseph von Jacquin, entry in Mozart's souvenir album (1787-04-11) from Mozart: A Life by Maynard Solomon [Harper-Collins, 1966, ISBN 0-060-92692-9], p.312
