The Meaning of It All
Richard Feynman
 In the first lecture, "The Uncertainty of Science" Feynman explains the nature of science, that it is a "method for finding things out", and that it is "based on the principle that observation is the judge of whether something is so or not". He says that uncertainty and doubt in science is a good thing, because it always keeps the door open for further investigation. The second lecture, "The Uncertainty of Values" deals with his views on the relationship between science, religion and politics. Feynman acknowledges science's limitations and says that it does not have the "value system" that religions have, but adds that it can be used to help in making decisions. He also stresses the importance of having the freedom to question and explore, and criticizes the (then) Soviet Union by saying that no government has the right to decide which scientific principles are correct and which are not. In the third lecture, "This Unscientific Age", the longest of the three, Feynman discusses his views on modern society and how unscientific it is. Using a number of anecdotes as examples, he covers a range of topics, including "faith healing, flying saucers, politics, psychic phenomena, TV commercials, and desert real estate".
