"we naturally pursue
those things that have the appearance of good, and avoid the contrary

Now where this
strong desire is consistent and founded on prudence, it is by the stoics
called Bulesis and the name which we give it is volition, and this they allow to none but their wise men, and define it thus;

volition is a reasonable
desire; but whatever is incited too violently in opposition to reason,

that is a lust or an unbridled desire which is discoverable in all fools”

Cicero
