A good example was the challenges that people had back in the 50s when the radio program, "The War of the Worlds" was played. This was a popular novel back in 1938 and on Sunday, October 30, 1938 at 8 p.m. this radio broadcast was done. Because people relied on the radio to give them the "correct" news, they believed that the broadcast was "true". This created a panic across the nation and people called radio and television stations to find out what they should do (Rosenberg 1). This example shows how it is difficult to know what is "real" and what is "not real" when we are talking about knowledge.
Descartes had a lot to say about knowledge and it is difficult for us to truly understand what knowledge is and how it is used in the world. On the one hand, we can say that someone "knows" something but we cannot really say how the individual knows what they know. In thinking about knowledge we have to go deeper and wonder whether knowledge is a belief or it is something that we learn. Descartes tells us that we must look at reality and determine what that is first before we can say what knowledge is and we must understand it without doubt. Descartes ideas seem rational although they are somewhat difficult to explain.(Newman par. 1). He believed that if any thought could be subjected to any doubt then it was false (Skirry par. 2). Although this idea has some validity it is this researchers opinion that his idea does not go far enough. If we were to categorize thoughts it would be difficult to tell which ones were "true" and which ones were "false" because there is always room for doubt. In fact, most people would suggest that their way of thinking was "true" no matter what it was and therefore our thoughts would be different on a variety of issues.
