 Derision or scorn is a sort of joy mingled with hatred, which proceeds from our perceiving some small evil in a person whom we consider to be deserving of it; we have hatred for this evil, we have joy in seeing it in him who is deserving of it; and when that comes upon us unexpectedly, the surprise of wonder is the cause of our bursting into laughter… And we notice that people with very obvious defects such as those who are lame, blind of an eye, hunched-backed, or who have received some public insult, are specially given to mockery; for, desiring to see all others held in as low estimation as themselves, they are truly rejoiced at the evils that befall them, and they hold them deserving of these (art. 178–179).
