It is something previously deliberated upon, and is formed with reason or thought. People don't deliberate about matters over which they have no control, but rather about things which they themselves can do. We deliberate about things which are possible, which have an unclear outcome and in which there is something indeterminate. Thus not all inquiry is deliberation, but all deliberation is a type of inquiry. The object of deliberation is the same as that of intention, but the object of intention is the specific reason for which a person acts.
Intention is a deliberate desire of things which are in our power to bring about.
The object of a wish is, in the unqualified sense, the good, but for each person it is the apparent good. For a virtuous man the object of the wish is the truly good, but for a bad man it may not be. A virtuous man judges things rightly. But the majority of people are deceived in their judgment of the good because of pleasure they consider the pleasant as equivalent to the good and the painful as equivalent to the bad. Therefore virtue is also in our power, as is vice.
