84. Moses adds, "from his youth," because this evil is concealed during the first period of life and sleeps, as it were. Our early childhood so passes that reason and will are dormant and we are carried along by animal impulses, which pass away like a dream. Hardly have we passed our fifth year when we affect idleness, play, unchastity, and evil lust. But we try to escape discipline, we endeavor to get away from obedience, and hate all virtues, especially of a higher order as truth and justice. Then reason awakes out of a deep sleep, as it were, and sees certain kinds of pleasure, but not yet the true ones, and certain kinds of evils, but not yet the most powerful ones, by which it is held captive.
85. Where, then, the understanding has attained to maturity, not only the other vices are found to have grown strong, but there are joined to them now sexual desire and unclean passion, gluttony, gambling, strife, rape, murder, theft, and what not? And as the parents had to apply the rod, so now the government must needs use prison and chains in order to restrain man's evil nature.
86. And who does not know the vices of a more advanced age? They march along in unbroken file—love of money, ambition, pride, perfidy, envy, and others. These vices are so much the more harmful as at this age we are more crafty in concealing and masking them. Hence, the sword of government is not sufficient in this respect; there is need of hell fire for the punishment of crimes so manifold and great. Justly, then, did Moses say above (ch 6) that the human heart, or the imagination of the heart, is only evil each day—or at all times—and here again, that it is evil from youth.
87. The Latin version, it is true, makes use of a weaker term; yet it says enough by stating that it is inclined toward evil, just as the comic dramatist says that the minds of all men are inclined to turn from labor to lust, Ter Andr 1, 1, 51. But those who try to misuse this expression for the purpose of making light of original sin, are shown to be in the wrong by the common experience of mankind; chiefly, however, that of the heathen, or ungodly men. For if spiritual men, who surely enjoy divine help from heaven, can hardly hold their ground against vices and be kept within the bounds of discipline, what can any man do without this help? If divine aid contends against the captivity of the law of the flesh only with fierce struggles (Rom 7, 22-23), how insane is it to dream that, without this divine help, human nature can withstand corruption?
88. Hence reason of itself does not decide upon the right, nor does the will, of itself, strive after the same, as a blind philosophy declares which does not know whence these fearful impulses to sin arise in children, youths, and old men. Therefore it defends them, calls them emotions or passions only, and does not call them natural corruption.
89. Furthermore, in noble men, who check and control these impulses, it calls them virtues; in others who give the reins to their desires, it calls them vices. This is nothing less than ignorance of the fact that human nature is evil. The Scriptures, on the contrary agree with our experience and declare that the human heart is evil from youth. For we learn by experience that even holy men can scarcely stand firm; yea that even they are often entangled by gross sins, being overwhelmed by such natural corruptions.
90. The term ne-urim denotes the age when man begins to use his reason; this usually occurs in the sixth year. Similarly, the term ne-arim is used to denote boys and youths who need the guidance of parents and teachers up to the age of manhood. It will be profitable for each of us to glance backward to that period of life and consider how willingly we obeyed the commands of our parents and teachers, how diligent we were in studying, how persevering we were, how often our parents punished our sauciness. Who can say for himself that he was not much more pleased to go out for a walk, to play games, and to gossip, than to go to Church in obedience to his parents?
