“The abolition of the evil is not impossible; it ought never therefore to be despaired of. Every plan should be adopted, every experiment tried, which may do something towards the ultimate object.”

Context: Accept the invitation so that the inviter may save you from what is so hard and dangerous to be saved from, so that, saved, you may be with him who is the Savior of all, of innocence also. For even if it were possible that utterly pure innocence was to be found somewhere, why should it not also need a Savior who could keep it safe from evil! –The invitation stands at the crossroad, there where the way of sin turns more deeply into sin. Come here, all you who are lost and gone astray, whatever your error and sin, be it to human eyes more excusable and yet perhaps more terrible, or be it to human eyes more terrible and yet perhaps more excusable, be it disclosed here on earth or be it hidden and yet known in heaven-and even if you found forgiveness on earth but no peace within, or found no forgiveness because you did not seek it, or because you sought it in vain: oh, turn around and come here, here is rest! The invitation stands at the crossroad, there where the way of sin turns off for the last time and disappears from view in-perdition. Oh, turn around, turn around, come here; do not shrink from the difficulty of retreat, no matter how hard it is; do not be afraid of the laborious pace of conversion, however toilsomely it leads to salvation, whereas sin leads onward with winged speed, with mounting haste-or leads downward so easily, so indescribably easily, indeed, as easily as when the horse, completely relieved of pulling, cannot, not even with all its strength, stop the wagon, which runs it into the abyss. Do not despair over every relapse, which the God of patience has the patience to forgive and under which a sinner certainly should have the patience to humble himself. No, fear nothing and do not despair; he who says “Come here” is with you on the way; from him there is help and forgiveness on the way of conversion that leads to him, and with him is rest.

Summa Contra Gentiles, III,126,3

But in 1793 the cotton gin was invented, shortly after the power loom in England. This was the onset of the industrial revolution. Almost overnight, a new industry or rather a series of new industries, proliferating worldwide, was born. It began with the growing of cotton but was followed by its manufacture into a wide variety of products, especially cotton cloth and cotton clothing. Suddenly, slave labor became vastly more profitable. In the decade before the Civil War, the value of slaves doubled. Once again, greed overwhelmed all other motives. From being regarded as a temporary evil, as it was at the founding, slavery came to be regarded as a positive—and permanent—good.

Context: Our strength grows out of our weakness. The indignation which arms itself with secret forces does not awaken until we are pricked and stung and sorely assailed. A great man is always willing to be little. Whilst he sits on the cushion of advantages, he goes to sleep. When he is pushed, tormented, defeated, he has a chance to learn something; he has been put on his wits, on his manhood; he has gained facts; learns his ignorance; is cured of the insanity of conceit; has got moderation and real skill. The wise man throws himself on the side of his assailants. It is more his interest than it is theirs to find his weak point. The wound cicatrizes and falls off from him like a dead skin, and when they would triumph, lo! he has passed on invulnerable. Blame is safer than praise. I hate to be defended in a newspaper. As long as all that is said is said against me, I feel a certain assurance of success. But as soon as honeyed words of praise are spoken for me, I feel as one that lies unprotected before his enemies. In general, every evil to which we do not succumb is a benefactor.
