This thesis was devoted to finding out the state of public opinion towards Roosevelt's "Four Freedoms" from 1941 to 1945, since these concepts were an important part of American dialogue during World War II. To solve this question a series of editorials and "letters to the editors" articles from a series of American newspapers in the period from 1941 to 1945 was analyzed, along with a collection of questionnaires from the Gallup Poll conducted during the same period. The analysis of the newspaper articles demonstrated that there existed a diverse spectrum of opinions on Roosevelt's "Four Freedoms" from outright dismissal to cautious skepticism to optimism on the ability of the United States to implement them in the post-war world. While analysis of the Gallup questionnaires showed that they did not directly engage with the issue of the "Four Freedoms," the responses to some of the questions on related issues such as sending U.S. troops abroad implied the existence of varied opinions on the "Four Freedoms." From these findings, the thesis has shown that public opinion as a whole from 1941 to 1945 expressed a diverse group of views towards Roosevelt's "Four Freedoms."
