President Kennedy addressed Rice University on September 12, 1962. The topic was the space effort.

Kennedy's speech is extremely persuasive. In terms of evidence, Kennedy provides several concrete reasons why the space effort is worth carrying out. He mentions how the United States has often been at the forefront of technology and innovation, citing, for example, the 45 satellites that had recently orbited the Earth. He also explains that nowadays, discoveries are happening at a great speed and more scientists are alive than ever before. He also believes in the possibility of science developing and people using it not for evil but for good. All these are good reasons to invest on science.

In terms of rhetoric, Kennedy's speech is even stronger. He uses very persuasive imagery, such as putting 50,000 years of human history in a 50-year timeline. He also brings up motivational events, such as reaching the moon or George Mallory's views on climibing Everest.

Overall, Kennedy's statement is persuasive in providing reasons to continue the space effort.
