This study traces the development of Lincoln-Douglas debate in Texas. The history of this type of debate from the Great Debate between Abraham Lincoln and Stephen Douglas to the Reagan-Mondale debates is considered. In addition, the merits of this type of oral controversy are explored. The reasons for the creation of L-D debate and its introduction into the forensic curriculum are discussed. In order to measure L-D's growing acceptance in the debate community, the results of a questionnaire of Texas Forensic Association debate coaches is evaluated. This study found that L-D debate is growing in participation in Texas schools. The distinct features of L-D enable it to be an innovative and challenging form of discourse.

This study deals with the Supreme Court decision in the case of Miller v. California, 413 U.S. 15 (1973). The study analyzes the arguments presented in the decision by both the majority and the dissenting justices according to the Toulmin model. This study begins with a review of viewpoints on the First Amendment, and how they will be applied to the question addressed in the thesis. The history of the obscenity controversy is detailed to explain the viewpoints that the Supreme Court has taken dealing with this problem. This study concluded that the arguments presented by the majority were not supported by ample evidence. The arguments presented by Justice Douglas in the dissent were more justified. This study concludes that more study needs to be conducted in the area of obscenity; and that the material should not be suppressed.
