Pluralism is hands-down the sanest view of ontology. In dualism everything is either substance or spiritual this seems to be only true for people who believe in spirits and souls, which I don’t. Behaviorism also contains flaws. In behaviorism, thoughts and mental processes are all explained in terms of behavior. By explaining everything in terms of behavior one could easily misunderstand or misrepresent a situation. With pluralism things can be explained as fitting into multiple categories. This view in my opinion is the most useful because it is a complex world that we live in and a complex world, require complex answers.
