they perfectly understood the meaning of the language they used, and how it would be understood by others; and they knew that it would not in any part of the civilized world be supposed to embrace the negro race, which, by common consent, had been excluded from civilized governments and the family of nations, and doomed to slavery. -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 genetic fallacy hasty generalization
Answer
Brief Explanations:
The passage assumes as a given that the negro race is excluded from civilized governments and doomed to slavery without proper proof, which is begging the claim - assuming the conclusion in the premise. Ad populum appeals to popularity, genetic fallacy judges something based on its origin, and hasty generalization makes a broad conclusion from insufficient evidence. None of those fit as well as begging the claim here.
