Huck Finn wrestles with conscience

 

A classic case of comic (but thematically serious) dramatic irony is Huck Finn's decision at the end of Mark Twain's The Adventures of Huckleberry Finn to free the runaway slave Jim, who has been sold back into captivity by two con men they have met along the way, the "King" and the "Duke."  Huck agonizes over what to do

     I went to the raft, and set down in the wigwam to think. But I couldn't come to nothing. I thought, till I wore my head sore, but I couldn't see no way out of the trouble. After all this long journey, and after all we'd done for them scoundrels, here was it all come to nothing, everything all busted up and ruined, because they could have the heart to serve Jim such a trick as that, and make him a slave again all his life, and amongst strangers, too, for forty dirty dollars.
     Once I said to myself it would be a thousand times better for Jim to be a slave at home where his family was, as long as he'd got to be a slave, and so I'd better write a letter to Tom Sawyer and tell him to tell Miss Watson were he was. But I soon give up that notion, for two things:  she'd be mad and disgusted at his rascality and ungratefulness for leaving her, and so she'd sell him straight down the river again; and if she didn't, everybody naturally despises an ungrateful nigger, and they'd make Jim feel it all the time, and so he'd feel ornery and disgraced. And then think of me!  It would get all around, that Huck Finn helped a nigger to get his freedom; and if I was to ever see anybody from that town again, I'd be ready to get down and lick his boots for shame. That's just the way: a person does a low-down thing, and then he don't want to take no consequences of it. Thinks as long as he can hide it, it ain't no disgrace. That was my fix exactly. The more I studied about this, the more down and ornery I got to feeling. And at last, when it hit me all of a sudden that here was the plain hand of Providence slapping me in the face and letting me know my wickedness was being watchd all the time from up there in heaven, whilst I was stealing a poor old woman's nigger that hadn't ever done me no harm, and now was showing me there's One that's always on the lookout, and In't agoing to allow no such miserable doings to go only just so fur and no further, I most dropped in my tracks I was so scared. Well, I tried the best I could to kinder soften it up somehow for myself, by saying I was brung up wicked, and so I warn't so much to blam; but something inside of me kept saying, "There was the Sunday School, you could a gone to it; and if you'd a done it they'd a learnt you, there, that people that acts as I'd been acting about that niggert goes to everlasting fire."
     It made me shiver. And I about made up my mind to pray; and see if I couldn't try to quit being the kind of a boy I was, and be better. So I kneeled down. But the words wouldn't come. Why wouldn't they? It warn't no use to try and hid it from Him. Nor from me, neither. I knowed very well why they wouldn't come. It was because my heart warn't right; it was because I warn't square; it was because I was playing double. I was letting on to give up sin, but away inside of me I was holding on to the biggest on of all. I was trying to make my mouth say I would do the right thing and the clean thing, and go and write to that nigger's owner and tell where he was; but deep down in me I knowed it was a lie -- and He knowed it. You can't pray a lie -- I found that out.
     So I was full of trouble, full as I could be; and didn't know what to do. At last I had an idea; and I says, I'll go and write the letter -- and then see if I can pray. Why it was astonishing, the way I felt as light as a feather, right stratight off, and my troubles all gone. So I got a piece of papter and a pencil, all glad and excited, and set down and wrote:
Miss Watson your runaway nigger Jim is down here two mile below Pikesville and Mr. Phelps has got him and he will give him up for the reward if you send. HUCK FINN.
     I felt good and washed clean of sin for the first time I had ever felt so in my life, and I knowed I could pray now. But I didn't do it straight off, but laid the paper down and set there thinking; thinking of how good it was all this happened so, and how near I come to being lost and going to hell. And went on thinking. And got to thinking over our trip down the river; and I see Jim before me, all the time, in the day, and in the night-time, sometimes moonlight, sometimes storms, and we a floating along, talking, and singing, and laughing. But somehow I couldn't seem to strike no places to harden me against him, but only the other kind. I'd see him standing my watch on top of hisn, stead of calling me -- so I could go on sleeping; and see him how glad he was when I come back out of the fog; and when I come to him in the swamp, up there where the feud was; and would always call me honey, and pet me, and do everything he could think of for me, and how good he always was; and at last I struck the time I saved him by telling the men we had small-pox aboard, and he was so grateful, and said I was the best friend old Jim ever had in the world, and the only one he's got now; and then I happend to look around, and see that paper.
     It was a close place.  I took it [the letter] up, and held it in my hand.  I was a trembling, because I'd got to decide, forever, between two things.  I studied a minute, holding my breath, and then says to my self:
     "All right, then, I'll go to hell" -- and tore it up.
     It was awful thoughts, and awful words, but they was said.  And I let them stay said; and never thought no more about reforming.  I shoved the whole thing out of my head; and I said I would take up wickedness again, which was in my line, being brung up to it, and the other warn't.  And for a starter, I would go to work and steal Jim out of slavery again; and if I could think up anything worse, I would do that, too; because as long as I was in, and in for good, I might as well go the whole hog.

On the basis of this passage, would you say that Twain believes that moral conscience is "natural" (innate) or "conventional" (a matter of one's particular upbringing, a social formation)? For Twain, is "conscience" the same as "the promptings of the heart" -- or something different?
