Question

analyzing a seminal us document
identifying a fallacy
yet the men who framed this declaration were great men—high in literary acquirements—high in their sense of honor, and incapable of asserting principles inconsistent with those on which they were acting.
—dred scott v. sandford,
supreme court of the united states
what type of fallacy or faulty reasoning is used in this passage?
ad populum
begging the claim
hasty generalization
genetic fallacy

Explanation:

Begging the claim is a fallacy where the conclusion is assumed in the premise. Here, stating that the framers were "great men" (premise) and then using that to support the idea that their principles are consistent (conclusion) assumes the very thing it should prove - that being "great" equates to having consistent principles. Ad populum is about popularity, hasty generalization is a broad conclusion from limited data, and genetic fallacy is about judging based on origin. None of these fit as well as begging the claim.

Answer:

begging the claim
