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.
On the contrary, Macrobius [*In Somno Scip. i, 8] reckons sobriety to be a special part of temperance.
I answer that, As stated above (Q, A), it belongs to moral virtue to safeguard the good of reason against those things which may hinder it. Hence wherever we find a special hindrance to reason, there must needs be a special virtue to remove it. Now intoxicating drink is a special kind of hindrance to the use of reason, inasmuch as it disturbs the brain by its fumes. Wherefore in order to remove this hindrance to reason a special virtue, which is sobriety, is requisite.
Reply to Objection 1: Meat and drink are alike capable of hindering the good of reason, by embroiling the reason with immoderate pleasure: and in this respect abstinence is about both meat and drink alike. But intoxicating drink is a special kind of hindrance, as stated above, wherefore it requires a special virtue.
Reply to Objection 2: The virtue of abstinence is about meat and drink, considered, not as food but as a hindrance to reason. Hence it does not follow that special kinds of virtue correspond to different kinds of food.
Reply to Objection 3: In all intoxicating drinks there is one kind of hindrance to the use of reason: so that the difference of drinks bears an accidental relation to virtue. Hence this difference does not call for a difference of virtue. The same applies to the difference of meats.
