When we do not know the truth of a thing, it is good that there should exist a common error which determines the mind of man, as, for example, the moon, to which is attributed the change of seasons, the progress of diseases, etc. For the chief malady of man is a restless curiosity about things which he cannot understand; and it is not so bad for him to be in error as to be curious to no purpose.

There is a God shaped vacuum in the heart of every man which cannot be filled by any created thing, but only by God, the Creator, made known through Jesus.

There should be in eloquence that which is pleasing and that which is real; but that which is pleasing should itself be real.

No one is offended at not seeing everything; but one does not like to be mistaken, and that perhaps arises from the fact that man naturally cannot see everything, and that naturally he cannot err in the side he looks at, since the perceptions of our senses are always true.

Anyone who does not see the vanity of the world is very vain himself. So who does not see it, apart from young people whose lives are all noise, diversions, and thoughts for the future? But take away their diversion and you will see them bored to extinction. Then they feel their nullity without recognizing it, for nothing could be more wretched than to be intolerably depressed as soon as one is reduced to introspection with no means of diversion.

God has given us evidence sufficiently clear to convince those with an open heart and mind.

Curiosity is only vanity. Most frequently we wish not to know, but to talk. We would not take a sea voyage for the sole pleasure of seeing without hope of ever telling.
