"What would be thought of an instrument, drawn up, legally drawn up, for the purpose of entitling the city of Rochester to a tract of land, in which no mention of land was made?..."
See in text (Text of Douglass's Speech)
To demonstrate his point, Douglass appeals to logos in a manner that likely resonated with Rochesterians. He hypothetically proposes that if lawmakers were to create a law that endowed the city of Rochester with a piece of land, but did not mention the actual piece of land, the law would be null. This concept is analogous to slavery—how can slavery be enforced if is never explicitly mentioned in the Constitution?
