Final answer:
The disagreement between George Mason and Mr. Heath on slavery highlights profound sectional divisions in the United States, rooted in differing views on political and economic liberties and the legacy of the American Revolution.
Step-by-step explanation:
The critical point of disagreement between George Mason of Virginia and persons like Mr. Heath of Massachusetts centered on the question of slavery in the United States. Mason, a delegate to the Constitutional Convention from Virginia, wanted to immediately end slavery and was unpleased with the Constitution's lack of a bill of rights.
Northerners like Mr. Heath, on the other hand, saw the question of slavery through a different lens, often concerned with broader political and economic liberties. The debate over whether territories acquired through the Louisiana Purchase would be free or slave added fuel to these disagreements, and the Missouri Compromise only temporarily mitigated the growing sectional tension.
In such a climate, the divergent perspectives of northerners and southerners, reflected in the opposition of figures like Mason and Heath, showed the deepening national division over the institution of slavery.
