Raillery (ironia) as an act of justice

"Mock these things in a merciful way in order to show them that they should mock and shun these ideas."

"haec tu misericorditer inride, ut eis inridenda et fugienda commendes".

     St. Augustine, contra Faustum 15.4, trans. Teske (WSA 20, 187; CSEL 25/1, 422 ll. 11-12).  Pascal, Provincial letters, no. 11:  "haec tu misericorditer irride, ut eis ridenda ac fugienda commendes."  Trans. Stothert & Newman in NPNF 4, 214:

"Laugh at these things, while pitying them, to show their falsehood and absurdity."

According to p. 311n6 of tom. 5 of the Bruncschvig edition of the Œuvres of Pascal, the heading is from Hugh of St. Victor's On Genesis.
