Question

how is verisimilitude used in Mark Twain's Huck Finn to argue again slavery?

I understand what verisimilitude is but i don't see how that would help argue against the idea of slavery

Answer 1

anyone?

Answer 2

At one point Huck decides he'll turn over a new leaf and attempts to pray and promise he'll be a good boy according to the rules of the antebellum south, including upholding slavery and all that went with it. He fails in his attempt to pray because he knows he can't do it.
He concludes that "You can't pray a lie."
Most Sunday School teachers would agree with that conclusion. The verisimilitude, or appearance of being true, is evident to praying people.
Twain uses that verisimilitude as an ironic play. The lie is that good boys uphold slavery. Huck had grown to love Jim. Jim was more of a father than Pap had been. Huck knew that he couldn't return to a way of thinking that classified Jim as less human than anyone else.
So the appearance of truth in slavery society is shown a lie on closer examination. The truth is closer to what Huck knew from life experience.
