The son of a slave, Benjamin Banneker, who was a farmer, astronomer, mathematician, surveyor, in his letter to Thomas Jefferson, he analyzes ways to use rhetorical strategies to argue against slavery. Banneker's purpose is to make Jefferson realize the damages that are taken by the cruelty of slavery itself and the inequality. He adopts a remorseful tone towards Jefferson in order to point across how all men should be treated equally, and not having people superior from others based on the color of their skin. Banneker achieves his purpose by using diction and syntax in his letter.
