Why, then, does truth generate hatred, and why does thy servant who preaches the truth come to be an enemy to them who also love the happy life, which is nothing else than joy in the truth -- unless it be that truth is loved in such a way that those who love something else besides her wish that to be the truth which they do love. Since they are unwilling to be deceived, they are unwilling to be convinced that they have been deceived. Therefore, they hate the truth for the sake of whatever it is that they love in place of the truth. They love truth when she shines on them; and hate her when she rebukes them. And since they are not willing to be deceived, but do wish to deceive, they love truth when she reveals herself and hate her when she reveals them. On this account, she will so repay them that those who are unwilling to be exposed by her she will indeed expose against their will, and yet will not disclose herself to them.
Thus, thus, truly thus: the human mind so blind and sick, so base and ill-mannered, desires to lie hidden, but does not wish that anything should be hidden from it. And yet the opposite is what happens -- the mind itself is not hidden from the truth, but the truth is hidden from it. Yet even so, for all its wretchedness, it still prefers to rejoice in truth rather than in known falsehoods. It will, then, be happy only when without other distractions it comes to rejoice in that single Truth through which all things else are true.
-St. Augustine, Confessions
