Whether derision is a special sin distinct from those already mentioned?

Objections

Objection 1 : It would seem that derision is not a special sin distinct from those mentioned above. For laughing to scorn is apparently the same as derision. But laughing to scorn pertains to reviling. Therefore derision would seem not to differ from reviling.
Objection 2 : Further, no man is derided except for something reprehensible which puts him to shame. Now such are sins; and if they be imputed to a person publicly, it is a case of reviling, if privately, it amounts to backbiting or tale-bearing. Therefore derision is not distinct from the foregoing vices.
Objection 3 : Further, sins of this kind are distinguished by the injury they inflict on one's neighbor. Now the injury inflicted on a man by derision affects either his honor, or his good name, or is detrimental to his friendship. Therefore derision is not a sin distinct from the foregoing.
