This is a video lecture on chapter 17, titled "Values in a Scientific World", of Russ Shafer-Landau's book, 'Whatever Happened to Good and Evil?' The argument that this chapter considers is one that claims that if one follow's Occam's Razor, then one ought to reject the reality of objective moral facts or laws. This is an argument for moral skepticism, and Shafer-Landau offers several responses to it and in defense of moral objectivism. In the end, he claims that this use of occam's razor defeats itself. This lecture is part of an introductory level philosophy course, Introduction to Ethics.
