I've started to use PowerPoint to lecture every 2-3 weeks, when I really need to focus on getting through complex or dense bits of the reading. In a week or so, I will be using PowerPoint to give a lecture on Kant's moral philosophy to my Intro students. When we discussed Utilitarianism, I found a very useful and funny clip from the show Louis CK which captured Singer's argument in Famine, Affluence, and Morality perfectly. I've been trying to find a clip from a TV show or movie that I could use to illustrate the Categorical Imperative or the Formula of Humanity, but I haven't been able to come up anything. I looked through the resource section of Teaching Philosophy 101 with no luck. Suggestions are most welcome.
