Drug misuse is not a disease, it is a decision, like the decision to step out in front of a moving car. You would call that not a disease but an error of judgment.
Vices are simply the errors which a man makes in his search after his own happiness. Unlike crimes, they imply no malice toward others, and no interference with their persons or property.
It is not the critic who counts; not the man who points out how the strong man stumbles, or where the doer of deeds could have done them better. The credit belongs to the man who is actually in the arena, whose face is marred by dust and sweat and blood, who strives valiantly; who errs and comes short again and again; because there is not effort without error and shortcomings; but who does actually strive to do the deed; who knows the great enthusiasm, the great devotion, who spends himself in a worthy cause, who at the best knows in the end the triumph of high achievement and who at the worst, if he fails, at least he fails while daring greatly. So that his place shall never be with those cold and timid souls who know neither victory nor defeat.
Error is only the opportunity to begin again, more intelligently.
Satan's masterpiece of counterfeiting is the doctrine that there are only two choices, and he will show us what they are. It is true that there are only two ways, but by pointing us the way he wants us to take and then showing us a fork in that road, he convinces us that we are making the vital choice, when actually we are choosing between branches in his road. Which one we take makes little difference to him, for both lead to destruction. This is the polarization we find in our world today. Thus we have the choice between Shiz and Coriantumr -- which all Jaredites were obliged to make. We have the choice between the wicked Lamanites (and they were that) and the equally wicked (Mormon says "more wicked") Nephites. Or between the fleshpots of Egypt and the stews of Babylon, or between the land pirates and the sea pirates of World War I, of between white supremacy and black supremacy, or between Vietnam and Cambodia, or between Bushwhackers and Jayhawkers, or between China and Russia, or between Catholic and Protestant, or between fundamentalist and atheist, or between right and left -- all of which are true rivals, who hate each other. A very clever move by Satan! -- a subtlety that escapes most us most of the time.
I feel a strong desire to tell you–and I expect you feel a strong desire to tell me–which of these two errors is the worse. That is the devil getting at us. He always sends errors into the world in pairs–pairs of opposites. And he always encourages us to spend a lot of time thinking which is the worse. You see why, of course? He relies on your extra dislike of the one error to draw you gradually into the opposite one. But do not let us be fooled. We have to keep our eyes on the goal and go straight between both errors. We have no other concern than that with either of them.
Now error and sin both have this property, that the deeper they are the less their victim suspects their existence; they are masked evil. Pain is unmasked, unmistakable evil; every man knows that something is wrong when he is being hurt.
A work that undertakes the refutation of vulgar prejudices cannot have so high an aim. It aspires only to clear the way for the steps of Truth; to prepare the minds of men to receive her; to rectify public opinion, and to snatch from unworthy hands dangerous weapons they misuse.
It is above all in social economy that this hand-to-hand struggle, this ever-reviving combat with popular errors, has as true practical utility.
