Either the thing is judged impossible, or it is done; and this, according as aversion or appetite triumphs at the last.

Now, the last aversion, followed by omission, or the last appetite, followed by action, is the act of _Willing_.

So-called Will, that has been forborne, was _inclination_ merely; but the last inclination with consequent action (or omission) is Will, or voluntary action.
After mentioning the forms of speech where the several passions and appetites are naturally expressed, and remarking that the truest signs of passion are in the countenance, motions of the body, actions, and ends or aims otherwise known to belong to a man,--he returns to the question of good and evil.

It is _apparent_ good and evil, come at by the best possible foresight of all the consequences of action, that excite the appetites and aversions in deliberation.
