Whether covetousness is opposed to liberality?

Objections

Objection 1 : It seems that covetousness is not opposed to liberality. For Chrysostom, commenting on Mt. 5:6, "Blessed are they that hunger and thirst after justice," says, (Hom. xv in Matth.) that there are two kinds of justice, one general, and the other special, to which covetousness is opposed: and the Philosopher says the same (Ethic. v, 2). Therefore covetousness is not opposed to liberality.
Objection 2 : Further, the sin of covetousness consists in a man's exceeding the measure in the things he possesses. But this measure is appointed by justice. Therefore covetousness is directly opposed to justice and not to liberality.
Objection 3 : Further, liberality is a virtue that observes the mean between two contrary vices, as the Philosopher states (Ethic. i, 7; iv, 1). But covetousness has no contrary and opposite sin, according to the Philosopher (Ethic. v, 1,2). Therefore covetousness is not opposed to liberality.
