What is it then that this desire and this inability proclaim to us, but that there was once in man a true happiness of which there now remain to him only the mark and empty trace, which he in vain tries to fill from all his surroundings, seeking from things absent the help he does not obtain in things present? But these are all inadequate, because the infinite abyss can only be filled by an infinite and immutable object, that is to say, only by God Himself.
He only is our true good, and since we have forsaken Him, it is a strange thing that there is nothing in nature which has not been serviceable in taking His place; the stars, the heavens, earth, the elements, plants, cabbages, leeks, animals, insects, calves, serpents, fever, pestilence, war, famine, vices, adultery, incest. And since man has lost the true good, everything can appear equally good to him, even his own destruction, though so opposed to God, to reason, and to the whole course of nature.
Some seek good in authority, others in scientific research, others in pleasure. Others, who are in fact nearer the truth, have considered it necessary that the universal good, which all men desire, should not consist in any of the particular things which can only be possessed by one man, and which, when shared, afflict their possessor more by the want of the part he has not, than they please him by the possession of what he has. They have learned that the true good should be such as all can possess at once, without diminution and without envy, and which no one can lose against his will. And their reason is that this desire being natural to man, since it is necessarily in all, and that it is impossible not to have it, they infer from it ...
426
True nature being lost, everything becomes its own nature; as the true good being lost, everything becomes its own true good.
427
Man does not know in what rank to place himself. He has plainly gone astray, and fallen from his true place without being able to find it again. He seeks it anxiously and unsuccessfully everywhere in impenetrable darkness.
428
If it is a sign of weakness to prove God by nature, do not despise Scripture; if it is a sign of strength to have known these contradictions, esteem Scripture.
