"Intelligence without ambition is like a bird without wings." What's your take on the meaning of this saying?

@Crazychick Neither had I, which was what prompted me to ask the question.
I came across the saying a Belgian crime-mystery film.
But I've subsequently discovered that the saying is widely thought to be a quote from Salvador Dali. On hearing that, it suddenly makes sense. Only a provocative surrealist artist could think like that and not see the flaws in the thought.
