Whether drunkenness is a sin?

Objections

Objection 1 : It would seem that drunkenness is not a sin. For every sin has a corresponding contrary sin, thus timidity is opposed to daring, and presumption to pusillanimity. But no sin is opposed to drunkenness. Therefore drunkenness is not a sin.
Objection 2 : Further, every sin is voluntary [*Augustine, De Vera Relig. xiv]. But no man wishes to be drunk, since no man wishes to be deprived of the use of reason. Therefore drunkenness is not a sin.
Objection 3 : Further, whoever causes another to sin, sins himself. Therefore, if drunkenness were a sin, it would follow that it is a sin to ask a man to drink that which makes him drunk, which would seem very hard.
Objection 4 : Further, every sin calls for correction. But correction is not applied to drunkards: for Gregory [*Cf. Canon Denique, dist. 4 where Gratian refers to a letter of St. Gregory to St. Augustine of Canterbury] says that "we must forbear with their ways, lest they become worse if they be compelled to give up the habit." Therefore drunkenness is not a sin.
