Oh Augustine, how did you know:

" If only the weak understanding of the ordinary man did not stub bornly resist the plain evidence of logic and truth! If only it would, in its feeble condition, submit itself to the restorative medicine of sound teaching, until divine assistance, procured by devout faith, effected a cure! In that case, men of sound judgement and adequate powers of exposition would not need to engage in lengthy discussions in order to refute mistakes and fanciful conjectures. But as things are, the intelligent are infected by a gross mental disorder which makes them defend the irrational workings of their minds as if they were logic and truth itself, even when the evidence has been put before them as plainly as is humanly possible. Either they are too blind to see what is put before their face, or they are too perversely obstinate to admit what they see. The result is that we are forced very often to give an extended exposition of the obvious, as if we were not presenting it for people to look at, but for them to touch and handle with their eyes shut(City of God)."
