Ambition is an excessive Desire for esteem.
Exp.: Ambition is a Desire by which all the affects are encouraged and strengthened (by P27 and P31); so this affect can hardly be overcome. For as long as a man is bound by any Desire, he must at the same time be bound by this one. As Cicero says, Every man is led by love of esteem, and the more so, the better he is. Even the philosophers who write books on how esteem is to be disdained put their names to these works.
