Introduction to Ethics - Occam's Razor - rational principles explained

This is a video explaining Occams's Razor, which is a normative, rational pattern of thought. It also explains how this principle differs from Inference to the Best Explanation and some other similar principles. There is also an explanation of an individual's ontology. To illustrate all of this, several examples are used involving the germ theory of disease and plate tectonics. This video was originally developed for use in an introductory level philosophy course, Introduction to Ethics, but it can be used for any philosophy course.
