There are a wide variety of approaches to Artificial Intelligence. Yet interestingly we find that these can all be grouped into four broad categories: Silver Bullets, Core Values, Emergence, and Emulation. We will explain the methodological underpinnings of these categories and give examples of the type of work being pursued in each. Understanding this spectrum of approaches can help defuse arguments between practitioners as well as elucidate common themes. Keywords. Emergence, Animal Models, Consciousness, Language Understanding
