What important contributions did Jefferson make to press freedom? On the influence and significance of these contributions. A: Jefferson, a modern American bourgeois politician, made the following major contributions to the freedom of the press: (1) He took the lead in proposing and actively trying to legislate for freedom of the press. It was with the efforts of him and the bourgeois democrats that the US Congress passed the constitutional amendment, which stipulated the provisions to protect citizens' freedom of speech and publication. (2) It points out the role of freedom of the press in democratic supervision of the government. (3) Expound the significance of freedom of the press to the exploration of truth, and think that it is the best way to open the road to truth. Jefferson's above viewpoint, at that time, was an important supplement and development to Milton's thought of freedom of the press, and directly promoted the establishment of bourgeois democracy in the United States. As far as today is concerned, it still has reference significance for all countries in the world. In the process of modernization, all countries should adopt legislation to protect citizens' right to freedom of the press. We should give full play to the role of press freedom in democratic supervision; We should create a good environment for people to explore the truth by implementing freedom of the press. Hope to adopt, thank you.
