Whether sobriety is by itself a special virtue?

Objections

Objection 1 : It would seem that sobriety is not by itself a special virtue. For abstinence is concerned with both meat and drink. Now there is no special virtue about meat. Therefore neither is sobriety, which is about drink, a special virtue.
Objection 2 : Further, abstinence and gluttony are about pleasures of touch as sensitive to food. Now meat and drink combine together to make food, since an animal needs a combination of wet and dry nourishment. Therefore sobriety, which is about drink, is not a. special virtue.
Objection 3 : Further, just as in things pertaining to nourishment, drink is distinguished from meat, so are there various kinds of meats and of drinks. Therefore if sobriety is by itself a special virtue, seemingly there will be a special virtue corresponding to each different kind of meat or drink, which is unreasonable. Therefore it would seem that sobriety is not a special virtue.
