III. MAN'S NATURAL DEPRAVITY AND HIS NATURAL POWERS.

V. 21d. For that the imagination of man's heart is evil from his youth.

56. This is a powerful passage, relating to original sin. Whoever weakens its force, goes straying like the blind man in the sunlight, failing to see his own acts and experiences. Look at the days of our swaddling clothes; in how many ways sin manifests itself in our earlier years. What an amount of switching it requires until we are taught order, as it were, and attention to duty!

57. Then youth succeeds. There a stronger rebellion becomes noticeable, and in addition that untamable evil, the rage of lust and desire. If one take a wife, the result is weariness of his own and a passion for others. If the government of a State is entrusted to him, an exceptionally fruitful harvest of vice will follow—as jealousy, rivalry, haughtiness, hope of gain, avarice, wrath, anger, and other evils.

58. It is true, as the German proverb has it, that sins grow with the years: Je laenger, je aerger; je aelter, je kaerger (worse with time, stingier with age). All such vices are so blatant and gross as to become objects of observation and intelligence. What, then shall we say of the inward vices when unbelief, presumption, neglect of the Word, and wicked views grow up?

59. There are those who are and desire to be considered powerful theologians, though they extenuate original sin by sophistry. But vices so numerous and great cannot be extenuated. Original sin is not a slight disorder or infirmity, but complete lawlessness, the like of which is not found in other creatures, except in evil spirits.
