Domestic scholars often think that Hamilton and Jefferson's press freedom ideas are opposite. In order to revise this dualistic thinking, this paper examines the three historical events that Hamilton had experienced. In terms of the debate on the Bill of Rights, Hamilton thought that they didn't need to write the Bill of Rights into the constitution, but he didn't deny the freedom of press. The reason why Hamilton supported the Sedition Act is that this act contained two principles which the law allowed truth as a defense and the jury had the power to judge both the facts and legal doctrines, and these two principles were fully embodied in Croswell case defense.On this basis the paper analyzes the historical connection of above-mentioned three events in terms of press freedom ideas. Finally, this paper further explores the absence of Hamilton and the construction of dualistic thinking framework in the domestic studies.
