Thirdly, a particular truth is hated, as being repugnant, inasmuch as it is in the intellect of another man: as, for instance, when a man wishes to remain hidden in his sin, he hates that anyone should know the truth about his sin.

Context

“Secondly, according as truth is in man's knowledge, which hinders him from gaining the object loved: such is the case of those who wish not to know the truth of faith, that they may sin freely; in whose person it is said (Job 21:14) : "We desire not the knowledge of Thy ways." Thirdly, a particular truth is hated, as being repugnant, inasmuch as it is in the intellect of another man: as, for instance, when a man wishes to remain hidden in his sin, he hates that anyone should know the truth about his sin. In this respect, Augustine says (Confess. x, 23) that men "love truth when it enlightens, they hate it when it reproves." This suffices for the Reply to the First Objection.
Reply Obj. 2: The knowledge of truth is lovable in itself: hence Augustine says that men love it when it enlightens.” source
