Final answer:
John Adams supported a bicameral legislature to ensure a balance of power and protect against tyranny by reflecting a mixed government with a natural aristocracy.
Step-by-step explanation:
John Adams believed that a legislature should have two houses, which is known as bicameralism, to provide a system of checks and balances and prevent any one group from gaining too much power. He feared the hazards of too much democracy and potential tyranny, which led him to advocate for a mixed government reminiscent of the colonial system but adapted to an independent republic. The two houses, ideally, would consist of different classes of men; an upper house with wealth and property requirements would act as a counterbalance to a more democratic lower house. Adams’s ideas were influenced by his desire to see the government reflect a natural aristocracy, with the ablest men serving and balancing the interests of the people.
